I like this video! So thank you for that! However, I see a train wreck happening if people “set it and forget it”. Here are some tips to avoid problems.
Lets say you set the NIMH settings to charge @ 3.0 amps, discharge @ 1.0 amps, discharge cutoff 6.0 volts, CAPA 7500 mAh, wait time 5 minutes, 3 cycles, safety timer 720 minutes (12 hours) (which is what Gregg suggests). The charger will discharge a module @ 1.0 amps down to 6.0 volts. It will wait 5 minutes, and then charge @ 3.0 amps until it has charged 7500 mAh or Deta V is triggered (aka “delta peak charging”), which occurs when the module is fully charged. Many chargers (such as the SkyRC charger) do not detect Delta V, but it appears this quad charger does detect Delta V. But some modules are old, and they will no longer trigger Delta V, so you will rely on CAPA of 7500 mAh to save you (or max charge time of 12 hours)? The problem here is that many older modules will be at their max potential voltage of 8.60 volts after applying just 4000 mAh.
A new hybrid pack will run over $2,000 and a rebuilt pack will run $750. An old module on Ebay runs $30. Here are some things you can do to avoid needlessly damaging your modules:
1) Set CAPA to 3300 mAh (for older modules), 4300 mAh (for good modules), 5300 mAh (for great modules). Watch max voltage reached and adjust.
2) Set charge to 3.0 amps. After two cycles, you can set charge to 3.2 amps.
3) Buy a SkyRC temperature probe ($10). Set max temperature to 83 F (for a single module), or set to 110 F (if left in the pack).
4) Set wait time between charge and discharge to 60 minutes (to allow module to cool).
5) Set discharge to 1.0 or 2.0 amps down to 6.50 volts. 6.0 volts is too low.
6) To refresh a module, you can discharge @ 0.1 amps from 6.5 volts down to 6.0 volts (once or twice). Following discharge, allow 20 minutes for voltage to drift back up to 7.20 volts. If the voltage does not rise on its own, apply a trickle charge of 0.1 amps up to 7.20 volts. Once a module is at 7.20 volts, you can apply a charge of 3.0 or 3.2 amps up to 8.60 volts.
7) When charging a module, the voltage may show 8.72 volts (or so). After stopping the charge process, the actual module voltage may be 8.55 volts or less (the max voltage for Prius modules is 8.60 volts). Delta V may be triggered around 8.72 volts. This quad charger appears to detect Delta V, but this is not guaranteed. Some modules are worn out, and will no longer trigger Delta V. If you have overcharged your modules, they may no longer trigger Delta V. If a module no longer triggers Delta V, this could be dangerous because the car’s BMS (battery management system) will not know when that module has reached it’s max charge.
8) When pairing modules for a pack rebuild, pair them based on similar resistance and mAh capacity. Do NOT pair weak modules with strong modules as an attempt to fool the BMS. It is better and safer to pair modules with similar capabilities. Pairing modules with similar characteristics will reduce the number of failures of a hybrid battery pack. If you have a super strong module, and you don’t have a good match, it may be best to leave that module out of the pack.
Excellent tips. Can you tell me how to best position the SkyRC temp probe to monitor external temperature? Just set it on top?
Great clarification, Thank you! What do you mean in step 1) watch max volts reached and adjust?
Another excellent video from Gregg. I watched your first video and followed your steps exactly and my results were excellent. As was shown in your video, use decent cables rather than the cheapies found online. I did notice that some of my modules required 5 cycles of discharge/charge while others required only 3. The torque values on the bus bar nuts are 48 in-lbs when reassembling the battery pack. Thanks again Gregg for sharing your valuable knowledge.
Gregg, I want to thank you for both of your excellent prius battery videos, Your help was invaluable in taking on my battery rebuild project, setting up the charger, balancing, assembly and disassembly of the pack.
A couple of things that might help others. I had to coax a number of modules thru 5-7 cycles to get them to 5000 mah, In the end I did not trust those cells or thought they would be the problems of the future so I opted to only use modules that got to 5000 mah in 3 cycles. also, I choose to lower the charge rate to 2.5 or even 2 amps on modules that tended to swell excessively, though It really extended the overall charge/cycle time.
Thank you for watching and writing in with the feedback.
One of the best videos I've watched on this subject thanks.
thanks for the DIY right to repair help - lets keep things working
Already looked at your other videos, this ones completes information, thanks
One of the best videos I have ever watched ,you're a boss thanks for sharing
Thank you for the detailed video! Great information that’ll help me refurbish my battery.
Greg job on the video. Very clear on the steps to complete the job.
Thank you for watching and leaving a great comment.
Excellent demonstration. I took your advice and bought 2 chargers and have discovered that I need 10 'new' blades, I am just testing them now, and some are not getting to 5 amp hours capacity. The ebay vendor claimed that they were all above 5 amp hours, so I am still cycling them but no joy yet....
Thanks for watching. I have had some batteries come in that took a few cycles to get back to good numbers. This may be from the batteries sitting on a shelf for a while before they are sold to us and shipped out? Not sure. Please write back and let us know how your pack turns out.
@@GreggFestoI think you are right, some have taken 7 cycles but they are all getting above 5 amp hours
I have the charsoon antimatter. Basically the same in operation and function.
When i started in 2018 it seems there was a lot less info.
Thankful for the recap on numbers for set up and what we want.
I can only charge at 7.2 or 8.4, it goes past 9v and upwards of 10v on 8.4. I dont like that, but unsure if its too much on the module
Hey greg i have 13 plug-in with 280,000 miles im in NJ averaging 50 mi to the gallon in the winter and somewhere between 60 and 80 in the summer when i first bought the car i got as Hi as 118mpg now I can't plug in as much so im down on mpg in the spring i might pull the pack and as i have RC chargers like what u use great videos 😊
Fantastic video Gregg! I learned so much from this and I thoroughly enjoyed learning your step-by-step process. I can't wait to start my 2006 Prius hybrid battery project soon!!
Thank you for watching and leaving a great comment.
Process completed.... changed out 8 bad modules. Dr Prius app says I got 97% capacity left and battery is in new condition! 😊 Will see how long this lasts before I get the orange triangle of death again 😂
Thank you for watching and providing awesome feedback.

All my modules all seems to be good on discharging but needed help getting up to full capacity.
Great video, the best one is come across for this topic.
Wow great video. Ordering charger right now....
Love seeing people diving into these subjects. Thank you!
I just got my hands on a 22 Venza from Hertz rental with 48k on the odometer and this gives me hope. I’m trying to find out how long my Lithium cells will last. Thinking if it would be a good idea to get a battery replacement to have while the inventory is available even though it’s still only 50k on the meter. Does this make sense to get something this early?
Thank you for watching. The more you drive the better battery will perform. Sitting for long periods is not good for them. For this reason I would not get a replacement pack and have it sitting around on a shelf - You may find out that it has gone bad on the shelf and you never got to use it.
great video - Gregg!! Thank You!
Thank you for watching
Damn man that’s badass. I love this
Thank you for the video Gregg, in the process of reconditioning. Do you load test these modules?
Thank you for watching. If the discharge capacity is 5000mah then they should be good to go. I put back in car, drive for a bit, then look at dr prius app for health.
Helpful video Gregg! I bought a new charger the same as your red one. I have been using it and charged half the pack and today when I began charging more cells I noticed the sound of the fan has weakened and the back of the charger is hotter than it was when I started using it. Do you know what could be causing this and how to fix this problem? I believe it is the larger fan in the back not blowing as strongly as before, the smaller fan in the front seems fine. Please give any tips or advice you have.
Thank you for watching. I have not had any problems with the fans so far. May be good to contact service at EV-Peak and ask for a replacement.
Thank you for the excellent video. I wish you could post a link to the exact make & model of the charger you talk about so I know I am buying the right one. I currently have a SkyRC but I am stupified over how the menu settings work. It all seems so confusing.
Thank you for watching. The charger I use is the CQ3 from EV-PEAK Corporation. They are available and many hobby shops and Amazon. There are 2 different colors (silver and red) that both work the same.
Thanks for the hands on instructional video. Would you use same voltage/amperage parameters for refurbishing 1st generation Honda Insight (2000-2006) and 1st gen Honda Civic Hybrid (long pipe 1.5v x 6 = 9v D type stacked) batteries? If not, which values (charge, discharge, volts, amps) would you recommend, or the same parameters used for Prius Gen 2 and 3 can be applied to 1st Gen Honda hybrid batteries? Thanks.
Thank you for watching. I am not familiar with the Honda batteries enough to provide setting details. I suggest visiting a Honda forum and getting that info from someone with more experience than myself.
@GreggFesto just fyi findings: Forum and CZcams users apply various similar setups, usually setting upper amperage capacity limit (charge) to 6500mV, that is the stock battery specs, but the later aftermarket batteries that came with 8Amp capacity (Bumblebee, Greentec, etc) seems to be handling your 7500mV charge capacity limit pretty well.
Thank you for the video, it was very informative....
Thank you for watching and leaving a comment.
Hi Greg,
I'm getting ready to do this process on 2008 Prius and thanks to your videos I feel confident about doing it myself. However i do have a couple questions I'm hoping you could answer for me!
First question, when i find bad cells and order replacements do i need to discharge and charge them, or is there a way I can check to make sure im getting a good cell?
Second, when i balance the pack im simply connecting all the positive/negative terminals in a row and letting it sit like that for 48 hours? I don't need to discharge and charge it all together?
Thank you for your time putting these great videos together!
Thank you for watching. I always run at least 1 cycle on the replacement batteries so I know what I received. This lets me know how it compares to my others and lets me know where to place it in the pack after balancing. During the balancing step you do not need to charge or discharge, just let them equalize. I hope you will write back in and let me know how your pack refurbishment comes out. How many miles are on your car and what year? Why are you refurbishing your pack? Did you get red triangle or are you experiencing reduction in mileage?
@@GreggFesto The Prius has 134,000 miles and I got the red triangle confirmed by a mechanic to be a hybrid battery failure, he also told me it was specifically cell block ten. However I plan on going through each cell as you do to see if there's any other performing poorly.
Thank you.
thqnk you very much for teach❤❤❤
Thank you very much for watching and leaving a great comment.
Good Job Gregg,
Very thorough, that's rare.
I have a Prius, watched your video, bought both cahrgers.
programmed them as instructed, 3 cycles, discharge/charge, ran into something that you didn't mention.
About 2 hours into my time from start. all but 2 modules read FULL. I pressed the mode button as you stated if End was displayed, the screen didn't indicate and cycle information, discharge/charge... nothing, just battery type selection screen like from the beginning.
all of the 8 modules read Full but 2. Number 4 and number 28, they were still running the cycles.
Not sure what to do now. Start again? Not sure what full means pertaining to a discharged and charged module just a couple of hours into the process.
When I pulled the battery and tested each module, all tested at just over 8V but 2 at 7V. Figured that they may be the culprit
Thanks, Have a Great Evening
Thanks for watching. You are correct, FULL is the same as END. Not sure why you would not see results when pressing the same button I did. On both of my chargers it is the far left button even though they are labeled differently. You can see this at 8:55 in the video. I suggest try a different button on the next finished battery and see if you can get results. If you find that it is a different one, please let us know as someone else will have this issue too. The voltage reading is not going to tell you much about the health, remember it is the capacity that counts.
Gregg, thank you for this video. I was able to purchase a “new” Dorman refurbed battery for $100 but it’s been sitting unused in a box since 2018. All of the cells I’ve tried read at over 6v but less than 7. When I try to do this, the most I’ve seen in the discharge mah is around 600. Are these modules all dead? I’m 0/8 right now.
Thank you for watching Aaron. You may have to run a couple of cycles on a battery that has been sitting for a long time. If the battery is able to be recovered then this process will do it. Usually I experience CAPA message with low discharge mah for the first couple cycles.
hello, my friend. Is it necessary to level a high-voltage battery according to voltage? if I want to change 1 pair? I’m just thinking of recharging the new element, up to the voltage of the neighboring elements.. for example, the new element will be 7.5 volts, and the batteries will be 8.0 volts.. just charge up to 8.0 and put everything together so as not to wait for a long time) 48 hours
Thank you for watching. I have always done the procedure as demonstrated in the video. I believe that you could change out some batteries based on voltage but you have no way of knowing what the capacity is and that is what matters when it comes to overall pack health.
Excellent video. How do you dispose of modules that have been determined bad? What is the charge voltage at 3amps?
Thanks for watching. We have recycle area at the dump in my city for batteries so I take them there. I do not know the answer to your volt/amp question.
Still waiting of cables and battery will follow to start refurbishing some batteries. I wanted to make a power bank out of a whole pack and connect it to a 3000 watt inverter to be used in black out. After asking around nobody could answer me. So went on Ai from Edge. If I run at 90% load so 2700 watt with fridge computer some stuff and let's say air conditioning, the final answer verified at 2 AI chats is 31 minutes so first that will kill the bank very quickly, and this makes this part of the project non feasible. Just wanted to let you know in case somebody ever wondered lol. Very dispointed, saved me couple of hours putting it together lol live and learn.
are U saying it doesn't work for your back-up
Hi Greg another question. Saw couple of videos going on safe side and charging at 3 amps. One guy said at 3 cycles would take average 9 hours per cycle ??? means 27 hours per 3 cycle discharge / charge ?? He said he was charging at 5 amps to go faster lol how much of a difference would it make at 3.5 amps ?? worth the risk ?? I know off of your experience you said 3 amps. I have 2 sq2 will be getting wires tomorrow to start charging recycling cells. Again thanks from Quebec, Canada
Thanks for watching. I usually stick to the 3a as you mentioned this is safe. I have gone to 3.2a but did not see much of a difference. I have not tried 3.5a or 5a myself. My understanding is that a slower discharge/charge cycle will provide a better result than a fast discharge/charge cycle due to the way chemicals in the battery respond to temperature (low amps = less heat). If you do try 5a could you please share your results?
@@GreggFesto lol Don't intend to, will stay with safe and sure results.
I have tried 4 amps and 5 amps, but I think I get the best results with 3 amps. When driving, I have seen the car charge as much as 90 amps. (90 amps / 28 modules = 3.2 amps). But this is not all the time, but it appears 3.2 amps is okay. In practice, I usually charge @ 3 amps. It is strong enough to reduce memory effect. Also, if you charge @ 4 amps up to 8.60v, it may apply less of a charge than if you charge @ 3 amps. I noticed that the total mah when discharging a module is more when you charge @ 3 amps compared to charging @ 4 amps. Doing so gives the module a little more time to take on the charge.
You are awesome!🎉
I got the cq3 charger (red one), I did the set up you have, already pass 10 hours but still making cycles. How long does it take for a cell to finish the cycles ?
Thanks for watching. The whole process takes me 2-3 weeks depending on the health of batteries. I usually check the charger every 12 hours or so.
Hey Gregg, thank you fornyou video. I've been following your tutorial but the capacities I'm getting on all the modules are all bellow 1,000. Except for #19 that just says 0 across the board. The battery was working great during the summer with great mileage but then i got the red triangle of death. Voltages were all really close to each other except for #19. Not sure where to go from here.
Thank you for watching. Double verify you have settings correct as I show. Be sure you are in mode discharge then charge. You should see the mah values rise within 3-5 cycles.
Thanks to your videos, I'm attempting to refurb my wife's Prius battery with the same charger you use. The process is taking much longer than i thought due to work schedule. I got most of the modules to acceptable discharge/charge numbers. I've gone back and rechecked some of the first ones and now the discharge isn't reaching the 5000 threshold before the charge is at 7500 capacity. Is it safe to say these are okay if I've gotten them to acceptable levels previously? I've already been at this for a few weeks and don't think i can go through them all again without running into the same issue due to time constraints.
If you have reached 5000mah on the discharge cycle and 7500mah on the charge cycle the battery is refurbished. It will equalize to the same voltage as the other batteries when you balance them together. I believe you are just about to get your Prius back on the road, woohoo!
@@GreggFesto Thanks, Gregg. Your tutorials have been invaluable!
Thanks
Hey Gregg, quick question for ya... I have the exact same BGUAC CQ3 Charger and in the User Settings, you didn't cover one section which says "Input Power Low Cut-Off"?? Mine seems to be set by default to 11V, but wondering if that's what you use as well since you didn't mention it in the video? Thanks. :)
Ps. Also in User Settings, there is another section for "Battery end volt" and then has options for LiPo, LiIo, LiFe, LiHv, and Pb but no NiMH... So just curious what you have that section set to as well or if it even matters? Thanks again. :)
Thanks for watching. All settings that I did not mention were left as factory. Please write back and let us know how your pack turns out.
Thank you sir
THANKS MY FELLOW PRIUS BRO.
Gregg, after you recondition the cells (cycling between discharge and charge) how much time do you let the pack rest, before unbolting the pack? I'm a little worried about the cells expanding if I unbolt the pack too early. Thanks for your help! Kevin
Thank you for watching. I forgot to mention that in the video. I feel the batteries with my hand, if do not feel any hot spots then I take apart, flip the batteries and balance. Please let me know how your pack does after you reinstall in car.
Hey Gregg. I was wondering if you can use this charger as a grid charger to charge the whole battery up to capacity similar to using a Maxx Volts grid charger?
Thank you for watching and commenting. I am not sure how that would work.
Great Video!!! will this process work on a Chevy Volt? I actually have a Hybrid Cadillac CT6 and I have had problems finding reliable service for it, including the dealership. I know a lot about the vehicle, but lack the battery discharger that GM recommends. Could I use the one that you used in this video perhaps?
Thank you for watching. This charger and process should work on most any hybrid battery but the settings may change based on the battery type, voltage, and capacity. I suggest finding a forum for the Volt and see if someone there knows the specifics for battery and refurbish charging.
Hey there Gregg, so after watching your video I decided to go after the charger as well. While I am happy that your battery pack was in much better shape, unfortunately I can't say the same for mine. On avg all my modules end up below 1000 mah. I did find a guy who sells batteries with a range of 3500-4500 mah & so far one of his has passed the test. However, because of how many modules the pack has in general, I'm gonna have to make multiple orders to ensure that I can take care of bills at the same time. Just for reference, I do have an 09 Prius with 254k miles. So I did learn the hard way to give the battery pack at minimum 10 years before taking care of it each time in the future.
Thanks for watching. How many cycles did you give your batteries before deciding they were not recoverable? I have had to run some 15-20 times before getting to the 5000mah value. I recently purchased some very good replacements from seller aloyhybrid on ebay for around $33 each. Each one was over 5500mah discharge. Sorry to hear you are having issues and hope you get your Prius back on the road soon.
So I've only run each battery once with the exception of the one that I purchased through eBay. There's only one from the original pack that seems to show some promise, so I'll give it another go. However I just don't have time to go wasting my electricity bill on cycling cells that just aren't showing any immediate promise. The downside of my situation is that I don't really have a nearby place where I can safely dispose of the bad batteries, especially since I've read that these nimh batteries aren't exactly healthy for the environment.
You should for sure run at least 3 cycles on each battery. Many times the first cycle will show low values or even CAPA with low discharge value.
You may wish to buy a used pack from a junk yard for $750 ($26 per module), or even $450 ($16 per module). I wish I did this instead of buying modules off of Ebay for $330.
Hi Gregg what is the weight of one prius pack around 50 lbs ??? Starting tomorrow to test and rebuild cells. I have a small table but won't take 100 lbs lol maybe 50. Also how many amp hour is a pack or how many is one cell? If I want to make a power bank at 16v or 24V. How does it compare to a 12v lead acid battery with 700 amp cold? thanks
Hello and thank you for watching. Prius pack weighs about 80 pounds. Each of the batteries (28) in there are 6500mah. I am not sure how to answer your power bank question as I use AC input power. Good luck on your refurbishment process, please write back when complete and let me know how it turns out.
What should the input power low cut-off voltage be set too on the charger?
Thank you for watching. I left mine at the default setting. I think that setting might make a difference if you were using DC input power from car battery or such.
Hello Gregg thanks for the video
quick question though, each cycle discharge and charge the battery 3 times or 5?
also how long does 1 cycle take ?
Thank you for watching. Yes, I usually set the charger up for 3 cycles to get a feel of how the battery does. If I see it will need a while to recover or I do not want to check on it as often, then I change to 5 cycles. The time it takes to go through the cycles will depend on how the battery responds to the charging and discharging.
Thanks for sharing
Thanks for watching!
Thank you for sharing your knowledge. I'm currently about half way through reconditioning my 2007 battery pack.
Quick question, if you don't mind: Is the number of cycles required to hit the 5000/7500 values an indication of the remaining life in a module, or is that number irrelevant as long as those values are reached? Asked another way, does a module that required 10 cycles to reach 5000/7500 have less life remaining than one that required only 2 cycles? Thank you for your time.
Thank you for watching. That is a good question, unfortunately I do not know the answer. I suspect that the battery which took 10 cycles to recover is not as healthy as the one that took only 2 cycles but just don't know. This would be a good question for a forum such as PriusChat. I have had some take over 15 cycles to come back around and they seem to work just fine. If you do get an answer to this from someone that knows, please write back in and share with us.
@@GreggFesto Thanks for getting back to me. If I do find an answer I'll be back to share.
I hsve some batteries I bought from a guy on FB. Is there a way to charge/discharge them without having them into compression at the battery pack? I ballooned one by trying without the compression yikes.
Thanks for watching. You should always put the battery under compression when performing this procedure. If you are not able to put them in the pack you can try putting the battery between 2 pieces of wood in a vice or clamp.
Would this work for a 2013 FORD C-MAX hybrid SEL VIN A hybrid battery? What would be the settings?
Thank you for watching. Yes, this charger will work on all hybrid batteries. The settings may be different as well as the removal/installation. I am not familiar with the C-Max, I suggest you check on some forums for your car and see if someone there knows the settings for the charger. I wish you best luck and happy motoring.
Will same process and settings work on a gen 1?
Mine is '03, 182k, p3030 code, garage report says 5 cells are 0
Have an odb2 on order for Dr. Prius.
Have blue driver
Why are the best cells grouped in the middle and not on one end?
Thanks
Thanks for watching. This charger should work on any of the batteries. I have not done a 1st gen Prius pack before so I am not sure if the settings may be different. I suggest you visit forum called PriusChat and ask there what the battery settings should be. When finished with the refurbishment of batteries it is best to put the strongest ones in the center of the pack as they see the most heat stress.
The Gen1 batteries are very similar to Gen2, so you can use the same settings.
great video, very helpful. i have a 2009 gs450h do you happen to know if these batteries have the same capacity and should i use the same charge and discharge amps when testing these⁉️
Thank you for watching. Your batteries are the same as these and can use the same settings. You will have 40 of them instead of 28.
Gold, currently doing a 2007 GS450h. I'll post on www.youtube.com/@HouseOnRoosevelt
Great demonstration, what does the mpg looks like before and after the reconditioning?
Thank you for watching. Before reconditioning the car system reported lower 30's MPG average - after reconditioning it was back to upper 40's MPG average.
I started my hybrid battery project today. Is it ok to leave the modules in the casing when doing the dishcarge and charge? Second, if my initial voltage reading before the cycle was 6.8, should I replace that one and not waste time with discharge/charge? Thank you so much!
Nice!!
Yes, you can leave the modules in the case.
I would run every battery no matter the volt reading.
Good luck, Please let us know how how it goes. I am interested to learn many bad batteries you find and what kind of mah readings you get.
I wouldn't waste time doing cycles on any module with a resting voltage of 6.8V. The resting voltage (i.e. the voltage you measure after letting the module rest unconnected for a while) you measure on a module should bounce back to around 7.2V even in a discharged state. This is because the resting voltage is more dependent on the underlying chemistry rather than how much charge is stored in the battery. This underlying chemistry ensures that NiMH cells come back to 1.2V/cell. Since you have 6 cells per module, that would be 7.2V. Anything lower than that strongly implies that the underlying chemistry of one of the cells is not allowing it to return to 1.2V/cell, hence your module reading 6.8V.
Greg after the last charge before you balance do you leave fully charged at capacity? I seen a Prius chat forum said that it could cause a high voltage error code…what do you think is best?
Thank you for watching. I leave them in the charged state. Never had any issue with doing it this way.
Awesome thanks, I started the process….already recovered a whooping 6 modules in 24 hrs. using 1 cq3 charger is not fun 😢
Hi I have followed your steps with the same charger. All batteries I have tried which is 6 now have not went over 500 mah. I did one battery 8 cycles. Some batteries went up a little and back down. Since the numbers are so low should I keep trying or mark bad?
Thank you for watching. I have had batteries that read low to start but they usually go above 500mah after a couple of cycles. I suggest check all settings again to be sure they are correct. If still these batteries are low after several cycles then they should be replaced.
Thanks Gregg for that amazing video, i have my Prius has been sitting for year cause the battery pack after watching your video i decided to refurbish all , i respect all your instructions. The voltage test before i started on each module are 7.94V on each only the first one i fund 6.69V . My worries is i fund CAPA message for every single module i restored at the first or second or third cycle i add one more cycle Example Discharge 3416 Charge: 7201 the second one is D-Ch 4952, C-7500mh two or three cycles on each module i tried to restore. If after 5 cycles the battery never reach 5000mh or 7500mh. do i have to replace all modules?
Thank you for watching. It looks to me as if your discharge value is increasing with each cycle and your charge value has reached CAPA of 7500mah. This is perfect results. Run cycles until you reach at least 5000mah discharge and you will be good. If you also have 7500mah on charge at same time then this is a great battery.
Thanks for the video Mr Gregg! Could you give me a link for the banana plug to alligator clip cables, please? From where did you get them? Thanks.
Thank you for watching. I added link in the description for the wires I purchased from Amazon.
Which type of welding wire did you use in the video?
I think was stainless steel. Anything metal will work. If you are installing new bus bars then you will have enough to do the task when combined with the old bus bars.
Greg!!
You do not cover settings fully!!!
Myself and others are having trouble with the "END" and Miliamps reading process...
If your using this newer charger (the red one!). It does not read out the cycles when I hit " mode esc"!!
PLEASE HELP!!!
DID I NOT DO INITIAL SETTING CORRECTLY??
DID I NOT START FROM THE RIGHT SCREEN DISPLAY??
Thank you for watching. I believe the settings that matter to this process are covered. There are some settings that are factory unchanged and some that do not matter for this process. When doing this refurbish you should run the discharge then charge cycle. Once you get to end of cycle(s) then use the far left button to scroll through results. This is the same button to hit on silver charger and red charger although they are not marked the same.
Did you ever figure out why you were having that issue? I seem to be experiencing it at times.
Will this exact procedure work on the 2012-2017 camry hybrid batteries? Thank you in advance for your response.
Thank you for watching. I do believe Camry has the same batteries so everything should work just fine.
Hi Gregg, using the same Cq2 or Cq3, is it possible to recondition a li-ion battery like the one used in Ford Fusion or other models. I am looking but find people selling used packs with mentioning 50% capacity but don't see video like your's where they recondition them. I see there is a li-ion mode in the menu, but is the procedure the same ? Thanks
Thanks for watching That is a great question which I do not know how to answer. At this time I have only used my CQ3 on the Toyota batteries. I would think that there would be a similar procedure but do not know the settings. Have you searched for Ford Hybrid forums?
@@GreggFesto Did not look into Ford Hybrid forums yet, was looking on google and youtube and find nothing other then dismantle. Will try in forums.
When I went to the website for the charger is says it shouldn't be used with hybrid car batteries or it'll cause damage to the charger. Have you had any issues?
Thanks for watching. Have been using this silver CQ3 for years with no issues except noisy cooling fan.
Hi greg my question is do ı need to change dead modules or can I fix the dead modules with your methot
Thanks for watching. This method will show you which batteries are able to be saved and which need to be replaced. It will bring back batteries that are getting weak. You will need to replace any batteries that cannot be brought back. The goal overall is to have no battery with a discharge value of less than 5000mah.
Is this battery pack feasible for solar back-up? does it have enough Ah ? I want to set-up (4) 50.1V
Thanks for watching. I am not sure if this battery is good for solar back-up. Hopefully someone here will read comments and they may have done this before? I wish you best luck.
Are you able to provide a guarantee after all that presider if you are doing that for someone? If all of them will be above 5k when D-churched how long would it usually last? Even tho I understand you never know I just want to have an rough idea. Thank you!
Thank you for watching. I do not provide a guarantee when doing this job. If someone did demand a guarantee, I would feel safe stating that it would be fine for at least a year. I have been doing this method of refurbishing for around 4 years at this time and have not had to redo a pack yet.
Hi Greg, I'm working on a 2001 Gen 1 pack. The Modules are rated at 6500 mah. So, two questions, my Capacity cutoff should be set to 6500 mah?... and Second... should I be looking to reach 4000 mah on my discharge reading. Thanks
Thank you for watching. I am not sure of the difference between Gen1 and Gen2 batteries. I suggest checking PriusChat forums. Gen2 batteries are also rated at 6500mah, the reason the charger is set to CAPA at 7500mah has to do with the way it reads voltage while the battery charges, you can learn more on this by researching "delta peak charging". I see you have more batteries than a Gen2 to refurbish. Hope you will write back and let us know how your pack turns out.
What if full is flashing after starting the cycles. Does that mean it is good and charged up. It did not give me any readings of discharge or charge when I hit mode.
Thank you for watching. After you get FULL message it means cycles are done. You should be able to see values when hitting mode button. I suggest trying again so you can confirm the discharge value is at least 5000mah.
Thank you so much. You have a gift for good direct instructions.
Hi can I use this charger to charge my Prius 12v battery?.I heard it's an AGM battery and we cannot use a normal charger so was wondering whether CQ3 has any settings to charge that
Thank you for watching. I suggest a charger such as Battery Tender or Genius that has a specific AGM charge mode.
Thanks for the response and appreciate all your efforts
Another great video Gregg! On average how long did it take for 1 cycle per module to discharge and charge? Thank you!
Thank you for watching. I am not sure how long a single cycle takes on average. It depends greatly on the health of the battery of course. I setup for multiple cycles and check on charger a few times a day. Some batteries like that the really good one in video are finished in 24 hours, some like the one that had to be cycled multiple times take days. This pack took 21 days with 2 chargers which includes refurbishing the 14 replacement batteries.
I have just gone thru this with two packs. Many of the modules take 8 hours per cycle, so that can total 24 hours for 3 cycles. It takes longer to charge the better the module, also they reach "capa" or capacity of 7500 mah that you've set to protect the battery from overcharging. if that happens as Gregg shows, the charge "times out" and you have to manually restart the next cycle.
Question Gregg, I’ve had a set of 4 cells that have said ended and full, but when I press the “Mode” button, it doesn’t show me the charge/discharge cycle periods. It just goes to the presets of the charge/discharge rates. Any help would be nice thank you and thank you for the helpful video👌🏽
Thank you for watching. If you got the END message the charger should have run all cycles that you selected without achieving the capacity setpoint. Is it possible that you are selecting the wrong button to view results? I believe it should be the one on far left. If you press the wrong button the results will be lost. Please let me know what you find out.
@@GreggFesto hey thanks for the response, the first time when I read Full, I made sure to press the far left button but the results were lost, I tried again when the modules read End and then I was able to see the results, I don’t know why I didn’t see the results the first time.
Another question if you don’t mind, how long did it take to “refurbish” the 28 cells with your 2x4 chargers before starting the balance?
The time it takes to do this job will vary based on the health of the batteries. Some could take 2 cycles to bring back to 5000mah while others could take 15 cycles to achieve the same results. I estimate 2-3 weeks is average for me to get the job done.
HEY Greg, love your videos. Just bought a 2007 lexus hybrid, battery problem. 40 cells, 7.2 volts and 6500mah capacity. I believe 2,3 gen prius cells are the same just fewer? Ive watched your settings and you are going to 7500mah when charging. Is this not too much juice for the capacity? Can you educate me ? Thanks man!
Thank you very much for watching and writing in. I am not a battery expert but rather just using the settings I was taught. I hope someone reading this will write in and drop some education on us both.
When discharging a module, it is safe to discharge @ 3 amps down to 6.40 volts. Once discharged, you could consider doing a slower discharge of about 0.1 amps down to 6.0 volts (but I would do this just once or twice). I have seen strange behavior after discharging a module down to 6.0 volts. I think this is because, the battery chemistry supports a nominal charge of 7.20 volts. Following discharge down to 6.40 volts, a good module will drift back up to about 7.20 volts (within 30 minutes). When you discharge down to 6.0 volts, the module may not drift back up on its own. If this happens, I would slowly charge the module @ 0.1 amps up to 7.20 volts. Once at 7.20 volts, you could charge it @ 3 amps to the max voltage (which is 8.60 volts). When the charger is charging, the charger may show the voltage is near 8.80 volts. But when the charger stops, the voltage likely will be 8.60 volts or less. I think this charging technique may damage decent, but older modules. It would be nicer if the charger could keep the range between 6.40 volts and 8.60 volts. If you are not careful, you could be needlessly damaging half the pack. Good modules will cause a delta V to occur (at max charge), telling the charger to stop. However, the Delta V feature can wear out in a module, and you could be overcharging a module by applying 7500 mah. If anything, I would change this to 6500 mah, and pay close attention to the current charge voltage. If the voltage slows down around 8.40 volts, that module may not be accepting any more charge, and I would stop at that point. It seems you are aiming for a perfect (like new) pack, which could be expensive at $33 per module. For me, I have two SkyRC B6AC v2 chargers. They do not have a fan, and I can charge and discharge modules without them getting hot. I am very impressed with this video. My chargers rarely detect DeltaV, so I was interested in seeing this video where the charger can detect Delta v (at max charge). After further testing with my chargers, I think charging the modules in the range 6.40 up to 8.60 volts is a safer and better approach. My modules do not even get warm, and I can see that my cycling them pays off.
So what if it capa out 7500 charge and 6497 for discharge is that a good number or to high for the discharge?
That is a great result. If only they could all turn out that well. Thank you for watching.
@@GreggFesto I have a few that’s in the 6000 range so see how the rest goes thanks for the info I watched your video like 10 times to understand it the correct way
Hi Gregg...thanks for this video!! Running my 1st (4) cells and (1) went from 3458/6982 on Discharge/Charge 5 to 2190/4921 on Discharge/Charge 6. I'm assuming I need to Discharge/Charge another 3x? Discharge/Charge mah was consistently increasing until 6th cycle. Also...is it typical for 3 cycles of Discharge/Charge to take 12-16 hours? Thanks again for the help!
Thanks for watching. Your assumptions are correct,,, try to run the battery that went from 3458 on 5th cycle to 2190 on 6th cycle some more. Sometimes they will fluctuate up/down in value and still come back to good health. Now it is very possible that is a failing battery that will need to be replaced and you will know this for sure if your numbers continue to fall or stay low. I have seen this many times. Regarding the time to cycle battery 3 times taking 12-16 hours, Yes this is normal from my experience. I hope this helps and I hope you will write back in with update when you have finished your pack refurbishment.
@@GreggFesto12 hours to cycle 3 times. Using a 4 channel charger like in the video would mean 4 days and nights. Any way to speed this up without buying a 2nd charger?
Thanks for watching. I do not know of any way to speed up the process. The better cells will reach the goal faster. I have had the process take up to 3 weeks. I just stick with it and think of what I will do with the $$$ I am saving.
@@GreggFesto Oh right I was hoping this would be a Friday Saturday Sunday weekend job, as will need the car to drive to work. If it take 2-3 weeks then that's too long.
@@ahmadmohamad6384I am assuming if you have more chargers to do each module at the same time it can be done over a weekend
Would this charger also work for a Gen 1 battery pack. 2003 prius?
Thank you for watching. Yes this charger will work for Gen1 batteries. The settings may differ though. The PriusChat forum may be a good place to check for settings info? So far I have only worked on Gen2 and Gen3 batteries.
So I just started doing this process thank you so much for making it so easy to follow by the way. Am on day 3 now have already done the process on about 11 modules and the low numbers don't go higher than two digits. Should I continue trying to bring them back or just buy new modules?
Thank you for watching and commenting. It is acceptable to have low values on discharge mah for a few cycles particularly if the batteries have been sitting for a bit. Have you double checked charger settings? If you have run more than 12 cycles on a battery and still are getting only double digits on the discharge mah values then that battery may not be salvageable.
I have it exactly as you instructed on video one other thing it's only showing me results for one cycle.
Are you getting display of CAPA or END or FULL at completion of cycles - before you look at the result(s)? There should be a reason your charger will only run 1 cycle instead of the 3 it is set for.
Capa at the end
From your description and the CAPA message it appears you are meeting the charge set point of 7500mah on first cycle. This is fine but you will need to run the cycles again until your discharge value is at least 5000mah.
Hi Greg, great video thanks for sharing, however I’m interested in purchasing the same battery chargers but I’m curious how long it takes to discharge and recharge each battery module normally? I’ll be using the chargers for business so it’s not for personal use, thanks in advance
Thanks for watching. The time it takes to cycle each battery module will vary based on health of the battery. Some batteries you can run 3 cycles and it is good while others may require 15 or more cycles. I start the charger then check it a couple times throughout the day so I am not usually around when a cycle ends. In my experience it takes around 16-20 days to do the whole pack.
Thank you, I just received my CQ3 charger today so I’m currently testing it on one module, I followed your settings to set up mines 👍🏼
Hey buddy.after my cycles are finished. I'm getting 000 on the low side on these on all of them. The high sides are shutting off at 75 hundred.i'm running these 3 cycles just as you described. What am I doing wrong or are these batteries just no good?
Thanks for watching and writing in. I suggest running another 3 cycles. If you have run 6 cycles and still get below 1000mah on discharge I would say that is a bad battery that cannot be recovered.
Keep in mind that what you are reading for numbers is the amount that has been discharged. That means the first time you run any of these, you will get a very low number most of the time because it was not perfectly charged already.
You've got to run them through at least two cycles in order to get a reliable number.
Did my 1st cycle and the numbers are super low - 00596mAh and 00864mAh. I am using the settings in the video, any suggestions?
I get low readings on first cycle many times, especially if the car has been sitting a while, this is nothing to worry about. The next cycles you can start to tell if the battery is coming back or not. You may need to run many cycles for results. I wish you best of luck and hope you will write back and let us know how your refurbishment turns out.
When process is done and wnat instal batery on car do we instal it fully charged?
Yes, When using the charger to run the cycles you select discharge then charge. This way the batteries are left in charged state for balancing and installing in the car. Prius uses HV battery to start car so if you try to install discharged batteries the car will not start.
Can it charge a few cells in a row? I have RX 30 cells*9.6V. I want to connect it permanently to 7,8,8,7 cells and charge it while parking
Thank you for watching. I do not know if that is possible. Sorry. Maybe someone reading comments will know? Maybe you can check online forums for answer. If you find answer, please write back in and let us know.
By 30 cells, I'm guessing you mean 30 modules. If each module is 9.6V, then you have 8 cells per module. Why would you connect a CQ3 charger permanently to a battery pack or any number of modules while it's still in the car? Also, what do you mean by 7,8,8,7 cells?
Hey Gregg, So my question now is, does it matter what gauge wire is used to balance the battery? I currently have 24 gauge galvanized steel wire wrapped around cell twice. Ordering bus bars and nuts.
And does it matter if Ieave wire attached for more than 48 hours?
Thanks for watching. I have not tried 24awg but it should work. I am not sure if the galvanizing will affect connection. I suggest checking each post with a muti-meter to make sure there is good connection from one battery to the next. Leaving battery connected in balance mode longer than 48 hours is not a problem.
Roger that. Thanks!
Hello Greg how long it takes to discharge and charge these modules three times?
Thanks for watching. The time it takes to run a cycle will depend on the health of the battery and how it responds to the process.
I cannot detect any heating on the batteries. If I program 10 cycles and 720 minutes, does each cycle last for 72 minutes? Of the 72 minutes, will it discharge for only 36 minutes? Why wait 5 minutes from charge to discharge? Is there any limit to the charge voltage? Where can I get a manual that answers these questions?
Thank you for watching. The batteries will get warm when using this process and will expand. The 720 minutes is a safety timer. The cycle time will depend on the health of battery and how long it takes to reach Delta Peak based on the settings. Waiting time between cycles is to let the battery cool down. Setting the charge voltage over 6.3V could cause damage to the battery so I stay around 6.0V-6.3V. There should have been a manual shipped with your charger. If your charger is the same as mine then EV-Peak is the place to contact.
Can this be used to charge inside the car? With orange plug pulled.
Thank you for watching. You need to remove all of the buss bars for charging and then put the batteries in parallel to balance them. Is much easier to do this on a bench.
Hello my friend, do you have experience with Honda Civic cell rehabilitation from 2006 to 2011 and can you tell me your advice? Thanks
I do not have any experience with hybrid civic. My advice would be to find a forum or online group for the civic and see if there are some settings that people there have used. The process for those batteries should be very similar if not the same.
@@GreggFesto Thank you for your interest and reply, thank you.
HI Gregg, awesome video! I have a question about reaching 5amps. Do you consider it good once it hits 5amp or do you run another cycle to be sure? I have a module that I ran with 3 cycles where in the first run it CAPA at 2245mAh. Then I ran again for 5 cycles but it CAPA again at 4th cycle but it was 5054mAh. The order for the 4 cycles in that 5 cycle run before CAPA was: 3064, 5319, 4575, 5054. Thanks!
I see low discharge number and CAPA on first runs many times after battery has been sitting for a while. This is normal. On your last 5 cycle run that reached CAPA on cycle 4 - this battery I would consider good however would not hurt to come back to it later and run it another cycle or two after running the rest of your batteries to be sure. I hope you will follow up once you have the pack back in your car and let us know how it goes.
@@GreggFesto after you balance for 48 hours, do you also change or just balance? If you charge, do you still charge at the 3.0A rate by just adding the leads to the welding wire?
The batteries will already be charged when you balance them so no additional charging is required. Once you remove the welding wire or buss bars you can put the batteries back into proper orientation and reassemble the pack. Let me know how your pack does once you got it back in the car.
@@GreggFesto Thanks Gregg for that amazing video, i have my Prius has been sitting for year cause the battery pack after watching your video i decided to refurbish all , i respect all your instructions. The voltage test before i started on each module are 7.94V on each only the first one i fund 6.69V . My worries is i fund CAPA message for every single module i restored at the first or second or third cycle i add one more cycle Example Discharge 3416 Charge: 7201 the second one is D-Ch 4952, C-7500mh two or three cycles on each module i tried to restore. If after 5 cycles the battery never reach 5000mh or 7500mh
Great resource! Any parameters for ford escape batteries?
You should also measure from positive post to bottom mounting lug. I had a battery pack that was leaking through the boss and causing a high voltage leak to ground fault.
Thank you for watching and commenting with a great suggestion.
What relationship does the 7500mAh upper limit have to the stated capacity of the cell? I’m trying to figure out what the parameters would be be for my escape.
The Toyota gen2 mAh is 6500, but I believe you set an upper limit of 7500.
The escape cells are rated 6V @ 5500mAh.
Is the 1000 over an arbitrary amount?
I’m not criticizing, I just want to approach the escape batteries with some reasonable test scheme.
I’ve been charging cells and subjecting them to a load test.
I’m using the ebc-a10h unit.
Btw the escape batteries are a real headache to get to. My daughters 08 Prius had the ground fault and I could probably tear down 10 Prius packs in the time it took me to do one escape.
I am not a charger expert by any means and do not know what the settings for Escape would be. I am using settings that were acquired from forum called PriusChat where there are many discussions about refurbishing the battery packs. Perhaps you can find the settings you need at a forum for Escape or join the PriusChat forum where one the people there who have better knowledge than I do about this subject could help. I appreciate you watching my video and hope you get the Escape going. A video of how you do it could be very helpful to others if you have time to produce one.
@@irritantno9 It sounds like there are 5 cells in a module (1.2v x 5 = 6v). Personally, I think a better mah for Prius is 6500 mah. For the Prius, the max voltage of a module is (6 cells x 1.433333v = 8.60v). For the Escape, it sounds like you have 5 cells (which are likely 1.2v each). Max voltage for Escape may be (1.4333v x 5 cells = 7.16666v. This is just extrapolating the data you provided here (of 6V @ 5500 mah).
Do we necessarily have to load test and plug the cells into the CQ3? Wouldn’t I be able to just balance the cells by connecting all the cells together with the wire? The code usually pops up only because the voltage difference is high. Good work as always! Keep it up!
Thank you for watching and commenting. The code will return due to the low capacity of the failing cells.
Check your scan tool, you can determine the lower capacity cell by watching the charge and discharge rate, the cell block that has the lowest voltage when discharging would show you which block has the loss capacity.
Thanks for the good video, I have a question. With the same mode (Ni-Mh/C=3.0A D=1.0A 3 cycle D>C) when I turned on the batteries on test, none of them passed, but the battery pack was disassembled, it was on a separate table. The elements get fat and none of them could complete the test, I really know that these elements are good, I just bought this device and wanted to test and learn how to use, please hlep me to trooblshoting this process
Thank you for watching. I can try to help. When you report that the battery pack was on a separate table are you stating that the pack of 28 batteries was on a separate table or are you stating that an individual battery, 1 of the 28, was on a separate table?
@@GreggFesto More precisely, I have 8 batteries separately, and I took 4 of them and connected them to this charger, they did not pass the test, they got fat. That is, it is necessary to battery pack was in it's frame? that they can't get fat ? is this correct ?
For example, I have 1 battery, but how can I test/restore it correctly?
I really want to study the operation of this device fully, I have charged the batteries separately with my custom own charger but not with 3A ( used 0.65A -1A in this range)
When the battery swells if there is nothing to contain the growth damage can be done. You should charge the battery in the assembled pack or under compression like between 2 pieces of wood in a vice. If you follow the steps in my video it will work properly.
@@GreggFesto Thank you very much, I will definitely try and let you know the results
Why you using mode ni-mh/c 3.0a not 5.0a?
i have a 2012 Prius C which i bought a replacement battery from a refurbisher that has a 1 yr warranty. I installed the battery myself which was easy. After getting it completely hooked up the hybrid warning comes back on just like before. Does this mean that there are bad cells in the replacement battery or is there somethung else I should be looking at?
Thank you for watching. You may need to clear the codes more than once and/or unplug the 12V battery for a few minutes after replacing the pack. Confirm the orange plug is properly installed with the locking tab pressed down all the way. Be sure all wires and plugs are connected. Did the reconditioned battery come with computer and electronics or did you reuse you old ones?
@@GreggFesto it can complete! even with the fan connected. I gave an obd2 code reader from Oreilly that i have plugged in several times and i did disconnect the small battery and put a small trickle charge on overnight. it’s puts out 1.2 volts and the dash lights up good. So do l need to take this to toyota and reprogram the computer or what?
If you have checked all connections, confirmed orange plug is properly inserted/locked, disconnected 12V battery for a few minutes, then cleared codes a few times it is possible you got a failed battery or have another issue. What did the company you purchased battery from suggest? If they are of no help and you have no specific code for what is the issue then you indeed may require diagnosis by a professional.
@@GreggFesto i will get ahold of them monday and see what they will say. i’m sure i did everything right BUT there is a possibility that maybe something is not plugged in good but i will double check. would my obd2 show the codes or does it have to be a different type of scanner that toyota uses
You may need a better reader such as Techstream or Autel to get more specific codes but you might be able to tell what the issue is with your current OBD2 reader. Please do let me know what you find out, I am interested to know what the resolution is.
will this process work for a system upgraded with lithium blades
Thank you for watching. Yes this process will work for Lithium Ion batteries as well. Be surer charger is setup for lithium instead on NiMh.
How long does it take to charge the batteries in the 5 cycles you did?
Also how many cells can the EV PEAK CQ3 can charge?
Also, does it take 48 hours to balance the cells or can I do it faster?
Thanks
The time it takes to run cycles will depend on the health of the battery. It usually takes me 16-21 days to do a whole pack with a CQ3 charger. This charger has 4 channels. Usually 24 hours to balance the batteries is enough however 48 hours will leave no questions that it is equalized.
@@GreggFesto what charger I should use to do 4 battery cells? And how long does it take to refurbish the 4 batteries? Also can I refurbish 12v car batteries too?
Can you comment on the gauge of the wires? Or even better, do you have a link to a 4mm banana plug to alligator? Thanks in advance!

The cq3 charger comes with 14 gauge cables (states right on those cables' insulation. Get yourself a thick cable from some goodwill store or a junk yard and the proper ends from the harbor freight tools and yoy will have excellent quality cables. Just make sure they are all identical length.
Thanks for the great prius battery videos.
I watched this video and purchased the same charger that was in the first video, only it's a red model. It says "BGUAD" instead of "EV-PEAK" and the buttons are labeled differently.
I made sure the settings were exactly what was in the video. I ran my discharge & charge cycle (3x) and when the cycle was completed, I pressed the left button as Gregg did in the video, except I didn't get the same result. When he pressed "Batt. Type" he was able to see the low & high mAh. When I pressed the button located in the same location but labeled "Mode Esc", it took me back to the menu. I ran the scan again thinking I needed to hold it down, but it did the same thing. The other buttons do not take me to the desired menu.
Any thoughts?
Thanks in advance.
thanks for watching. I hit the same button location on both chargers even though they have different labels.
did you figure this out @andyaeschbacher7822? I just did the same thing, finished the scan and when i hit the Mode/Esc, it did not show my cycles at all, just went back to main menu. I also have the BGUAD, but it's EV-Peak on load screen when you turn it on.
i figured it out. the problem is not all chargers that come from amazon are always on 110. i bought two, one was 110 and the other was set to 220. when the 220 got done with the discharge, it would try to charge before failing with INPUT VOL ERR and quit. so what we thought was done was never done so there were no values to show when you clicked MODE/Esc.
@andyaeschbacher7822 and @leakingimplants - @GreggFesto, did you find a solution. I have the same thing, I hit the far left button and it goes to home on 1,3&4, but on 2 it works as Gregg showed. Since #2 works as shown, I think I must not have exactly the same settings, but I can't see where I went wrong.
Thought I would reply just in case it helps others along the way. After checking and even triple-checking to make sure my settings matched Gregg's instructions, I did a factory reset on all 4 QC3 modules and reentered Gregg's settings. 'Bingo', it seems to be working as planned. However, since the first 4 battery modules charged showed a flashing CAPA, therefore I could only see 1 cycle, and 2 of those modules had less than the desired D - 5000.
On the bad modules, why didn't you go lower voltage on cycles? With a lower current
Thanks for watching and commenting. I have been told that it could be detrimental to discharge under 6.0V but have done it before and did not see much difference. Lowering the current does seem to help some but adds considerable time. I may try the lower current settings on some of the batteries I replaced from this pack and see whats happens. If good results, I will make a video.
so at 16:39, just hook it up with solder wire in parallel and and let it sits for 48 to balancing (without connect the solder wire to charger right?) Thanks
Thank you for watching. I used TIG wire which is stronger than solder wire but I think solder wire should work. The important thing is to connect all positives lugs to each other and connect all negative lugs together with good connection. Do not connect to charger. When they sit for 24-48 hours, the batteries will all become the same voltage as each other.
Got all reconditioned and battery looks good but still “ check hybrid system “ message pop up and car wont start. Can it be blown fuses somewhere or any other issues? Thanks for your input in advance.
Code saying Check Hybrid System could be something other than battery. Is this the same error you had before reconditioning the pack? If yes, Then certainly you could have blown fuse or a failed part. I would first check that the orange plug for battery is completely installed and the latch for it is locked properly. If problem still exists, check that all of the plugs were reconnected correctly to the pack and the pack modules. If this does not solve issue, re-scan for codes and see if there are more clues to what could be issue.
@@GreggFesto yes it happed before battery conditioning too, i checked the voltage today on the output port wire back into the vehicle it doesn’t have any voltage which it should shown high voltage.
Perhaps you have wire or connection that has failed. I would trace back that wire until you find where is no connection point to battery. another alternative would be to post on forum PriusChat for help. That is a great resource for Prius information. Please if you can keep us updated on what you find is the issue.
If there is any mode to know the capacity of the batteries soon? let's allow already has sufficient capacity for the element and does not require additional training. So that we don't have to wait for additional hours
Thank you for watching and commenting. The easiest way to simply determine capacity is to use dr prius app. This will narrow low capacity to blocks of 2 batteries each.
Another simple way to determine capacity is a load test on each battery to determine which are failing and which are good but this method does not have the accuracy of the charger and will not refurbish the battery like the charger. The load test is performed by connecting an automotive lamp to each battery and letting it run for a fixed amount of time. The time of test will depend on the type of lamp you use. When doing this to each battery you will see that some still hold bright light at end of test time while others dim. The batteries in which the light dims quickly have less capacity. There are many videos on CZcams of this.
@@GreggFesto Yes, I also know a lot about those methods, I just thought that this device could perform a quick test to determine the capacity of a specific 1 battery
Today I received the panlong obd scanner and I will test the dr.prius soon
