- So I've made a video in the past of symptoms your bad hybrid battery might show, but it left out a lot of symptoms that I'm now experiencing with my battery pack that is going bad, yet again.
So here is an updated list of some more subtle signs that your hybrid battery may be going bad, that you can use to diagnose your own hybrid battery on your 2nd generation Prius.
Oh - Also one more symptom I forgot to mention is reduced MPG's. When my battery pack was in better condition, I was getting 36ish MPG in town and 45ish MPG on the highway. Now I'm getting about 30 MPG in town and 38 MPG on the highway.
Torque Pro is the app I was using

Good video! I have a 2004 Prius that had the hybrid battery Christmas tree come up. I replaced two of the cells for 45$ off eBay. I replaced them at 192,000 a year ago. The car now has over 220,000 on it and still running strong. I would gladly drop a new battery in it when the time comes. I have never owned a car that is so reliable and that hasn’t cost me tons of $$ to maintain. Riding it until it’s wheels fall off. Love the car.
Kurtis Lane hey how did u do that and where are you located? Lol
That's pretty impressive. I have 284k on my 2006 BUT I bought it from a friend who had the whole battery replaced at 99k just before his warranty expired. It was technically fine, but he had some light coming on and when the dealer was like ah no it's ok he was just fuck that replace it now!! So they did :D
How can i find someone in my area to install my modules
@@benjmiester you poor saps I have a volt that's at 430k and nothing but regular maintenance. My gf drives that now and I have a 2019 bolt. Yes volt to bolt thing should last till climate change is dealt with or we die lol.
Good to know! Mine has just over 200000 on it too. Runs like new as well.
Best explanation of Prius Hybrid Battery Pack Deterioration signs, symptoms, and solutions. Thank you for sharing!
I liked this so much I subscribed. Thank you for the Link to the app. Thank you for the tips on were to buy the batteries as well.
Thank you for a most useful and well focused presentation.
Excellent video. Unfortunately, I have all of these issues in my 2004 Prius, including the battery cooling fan turning on when parked. In 16 years I never noticed that vent before. I thought I was missing a piece of the back seat when I heard the fan!
Great presentation on troubleshooting. My nephew owns a 2007 Prius with similar issues. Your video has given me a better understanding on what to look for...Thanks!
Thanks so much. Very informative... great job!
Excellent presentation.
Thanks so much👍
Good video. Firstly As an engineer this is first video I have heard people talk about battery problems relating to keeping the battery cool.
You are an absolute hero - I bought my 2007 Prius as a wrecker off a towing guy for 1500 with simple cosmetic damage. The battery has been giving me hell recently and I'm guessing it's because the poor car sat in the dude's lot for a few months without any TLC. Everything that you described; the loud fan, the sluggish movement, the check lights -- IT'S ALL HAPPENING. My grandad is not at all aware of how hybrid cars work, so I'm doing what I can to learn how to fix it myself. I love this video, and I hope maybe I can ask questions later on? Thank you so much for your work!
My 05 crapped out after 11yrs.... 155k.....Dealer quoted me 6k for new pack (said it with a straight face)....Prius forums told me to call Toyota of america.....they took all my info....called me back and said they can help me with cost by slashing the price in 1/2 twice....ending up paying 1600 for new pack. God bless Toyota.
bradley shefmire calling Toyota of America. Good call!
I had a similar deal with an HID headlamp. Dealer wanted $400 (claimed they had to pull off the entire front end of the car). Toyota of America said, "Pay it and send us the bill." Got a check, pronto. Next time it happened (don't flash lights on and off, and some bad ballasts are out there) I got a bulb from eBay for $50 (it's $125 for same Philips bulb at the dealer) and followed a CZcams video on how to do it in 2 minutes.
That sounds pretty good I will definitely pay $1600 for a new battery pack specially if it has warranty.
Toyota replace my seat belt on my 2002 Tacoma at 180,000 mile even if it was out of warranty.. I just added a 2013 Toyota Prius and never have I driven such a fantastic car, thanks Toyota...
bradley shefmire
My hybrid battery failed yesterday. I called Toyota of America this morning. They took all my info and said that they didn't sell any parts at their headquarter and referred me to contact Toyota dealer directly. I did speak to the dealer b4 calling them and wad told 5k for a new pack. Do you happen to still have the phone number when they called you back? Thank you.
My 2008 130 K he’s doing good and garage kept battery is so far great just hope I can get another five years out of it. Thanks for all the useful information I’ll keep an eye on everything
This video was great, super informative, well made and really helpful! Thank you so much!
It's extremely important for any Prius owner to understand the battery vent, and particularly so for those that own a Prius C. The Prius C doesn't have the vent intake located up high like the regular Prius. The Prius C battery vent intake is located in the forward side of the rear seat bottom on the driver's side. See your owner's manual. It's not in an ideal location as packages and so forth can block the vent. Also, being located near the floor they will pull up dust from dirty carpeting and dog hair. They do vacuum easily without disassembly if the car is kept clean and the vent is vacuumed each time along with the interior. Anyone receiving a battery hot message (or suspect that the car interior was not always kept clean) needs to remove the cover panel along the front side of the seat (just push-in the center of the round pop tabs) and remove just the panel on the driver's side. (there's two panels that at the bottom seat front) Behind the panel is a fiber vent filter and this needs to vacuumed clean to restore proper air flow to cool the battery. To reinstall the round pop tabs, push the center pin outward on the side you see when installed, insert the pop tab into the panel holes , then lock the tab in place by pushing in the pin so it's flush with the pop tab.
Thanks
Which one is the Prius c
@@bobbobby2978 The Prius C is the smallest Prius, when Toyota used to have three sizes of Prius. They were discontinued a couple/few years back. Interestingly, after the first few years of production, Toyota changed them to use more gas. I felt that was a move because the C version was becoming too popular and cutting into the market of the regular size Prius. Our Prius C has been a wonderful car.
That's some great advice. Recently I have been hearing a gurgling sound by the passenger side under the dash i know this has nothing to do with the battery but I have air bubbles coming from the radiator, Holes or reservoir i checked yesterday and the reservoir looks empty! I opened the radiator and it's full i checked the cap and it looks good. Im not a mechanic but I want to try and make it bleed. The engine wasn't overheating no coolant came out of the car when it made this noise also the person I bought it from installed a new water pump! So What is going on here? I dont trust mechanics in my opinion i think most mechanics are scumbags just like used car salesman.
I know this is off topic but The Government needs to crack down on these people selling duds especially to a single mother with 2 kids who saved up money for years to get a 8,000- 10,000 Dollar car for it to break down after a month. Im not saying all used car salesman are bad but most are. If they won't give me a warranty i will not buy.
Thanks for the awareness bro really helpful
Nice, thanks a lot for making this video!👍
Got 290K on my O6' Prius and runs like a new car, I use Amsoil Full synthetic Signature series fluids in this vehicle, Engine & Transmission I occasionally once every year or two will get a bad cell, I have no problem fessing up a few bucks for this car, Best car ever!! Going to run this car till it blows up!! No leaks in this vehicle its super clean in and out looks like new. Run it!!
I agree 👍. 🎉
Thank you so much for this. Your video was extremely easy to follow for me (i dont know much at all about vehicles). You did a fantastic job presenting this information. Awesome video! Subscribed!😊
I have 193k on my Prius, and it still charges up to green status in the Texas summer heat. It's not as often as when it cools back down, but it seems to be still charging and discharging as normal. I love this little car. Never thought I would own one. I'm not a tree hugger, and don't like the smell of my own farts. But I do like the way this little car works, Smooth and quick in everyday traffic. I romp on mine and it gets over 40mpg. I also stealth camp in it when traveling across country.
what year?
🤣
So wait if you don't like the smell of your own farts you're definitely a tree hugging snowflake 🤣

Best video out of all of them.
I think you're right about the speed of the charge and discharge. I experienced this on the old HV battery in my Prius. I had a 3rd generation battery installed on my 2nd generation prius, and this battery charges and discharges much more gradually.
AM Interested to know this if it is possible to replace second generation battery with third gen
@@tanzaniacarschannel6975 how can i get the soft
Great Video! Thanks Dude!
Thanks for posting. I replaced two of my modules two years ago, and then follow up every year with a grid charger/reconditioner treatment in the springtime. Still running very strong, fingers crossed. One thing I found was important, and it caused me to have to disassemble and reassemble my battery the first time I rebuilt it because it still acted like it was failing with the replacement modules installed, was it is real important to clean and recondition your battery bus bars and their terminals, and also to properly torque them down to the recommended specifications. Perfect modules, etc, will still act bad if the bus bars are not torqued and conducting properly.
What is the torque value of the bus bar nuts?
Good job, man. Thanks
Thank you thank you! This helped me a lot. My partner’s 05 just had a reconditioned pack put in 8 months ago and that stupid Christmas tree came on. I nearly had a heart attack. It ran down quickly the night before but was holding a solid charge up until then. It only goes down to purple when we sit with the AC or loud music on for 15+ minutes. But when he normally drives it’s almost always at green and when accelerating, it maybe loses one or two bars. Never more than that. I had detailed the car and added some small interior lights and my guess is that since I let it sit with the ignition on and the ac on that I drained it so low that it tripped the system. Cleared the codes and it hasn’t done it since. I’m going to have a pro look at the cells and see if there are any failing ones and just have him install the ones I bought.
Thanks for sharing. Let us know how it goes. I'd be interested to see how the install goes on the new mods. And if you do the load test, that would be cool too.
I made a brief video overview of the replacement here - czcams.com/video/xMaKwNlEwuU/video.html
It drives alright know, kind of still hit or miss. I think I have more faulty modules in the pack but I just don't have the equipment to properly load test every single one and then power balance the whole pack so they all match.
Great info, thank you.
Very good and instructive video. Thank you
Good video friend thanks for the information.
Hi its relay very important to know more and more of the Priuses veiicle how they fails . keep ur head up 👍
Awesome and helpful....thanks!
Great work
Thank you for sharing. This is great. Now I need to find a decent obd 2 Bluetooth scanner. This is great.
Wonderful presentation
Your signs sound exactly like the problems I'm having on my Prius. I ordered a OBD tester and I'll get the software for the phone. Then I'll be able to see what's going on with the hybrid battery.
I’ve had a Prius for 10 years. Before I purchased a used Prius, I was skeptical and asked several taxi drivers. They all said their old Prius ran over 400,000 miles and never had an issue with the NiMH battery. As a matter of fact, they all swear you could transfer the battery to another car and run it another 400k miles. They only had to retired the vehicle because all the mechanical and structural parts warn out. Needless to say for the time I had it, no issues at all. Thing to keep in mind is the auxiliary battery is small and needs a bit more monitoring. IE, disconnect auxiliary battery if you’re going to store the Prius for months. Battery naturally drains in non use mode and since it’s a tiny battery, it drains faster. I understand they’ve gone to Lithium for the Prius Prime but I can say I have 100% confidence in the NiMH.
My grandfather's hybrid Camry battery died around 150,000 miles because his was unfiltered. He installed an aftermarket filter when he replaced the battery, and it's still going strong 200,000 miles after the replacement. Around 350,000 miles the regenerative braking system failed so he finally upgraded to a newer model Camry hybrid.
@@Will-wb6nk Camry Hybrid battery could be Lithium. The old Prius uses NiMH
@@josephlim8941 it's an OEM replacement of the exact same battery. I know a little more about this than you hun, he's my grandfather not yours lol
@@Will-wb6nk I understand it’s OEM. Question is OEM bat LiMh or NiMH hun.
@@Will-wb6nk I understand it’s OEM. Question is OEM bat LiMh or NiMH hun.
As batteries age, their internal resistance goes up, so more heat generated for a given current flow.
NEW SUB HERE! Thank you so much, man!
Great video, what is the App/Module that you used for checking the voltage of the Cells of the Hybrid battery?
Hello CtrlAltDefeatTV. What obd 2 scanner did you used to check the hybrid battery with torque pro app? Thanks
Prius from 04-09 are the best car for work good on gas which can't beat it... I had toyota prius 04 at 171k hybrid just goes out i luckly i can still drive to a local shop at 24mile they replace 3 module battery pack and work great thank for your video very helpfull thank..!
Great video
Hi, what is the app you use to monitor batteries?
You usually just want to replace the whole battery pack when a module OR cell goes out. You can replace one, but the others are not far off. That's if you don't see any corrosion, which you can just clean and be good.
Thanks, bro!
You are so knowledgeable! Even after listening to you I know I can’t do those things. I just bought a 2008 Prius and want to take it to a dealer to check out EVERYTHING. Could you give me a list of wording to say to them so I can get it checked? I have learned just saying everything doesn’t work, to them it means minimal and I get charged the hourly fee. (That’s my Dodge dealer) BTW, I’m 72 and a lady. Usually get taken advantage of. I don’t mind paying for what I really need. I believe in maintenance .
Informative presentation well presented. How many miles on the vehicle I wonder?
I just had the red triangle with the exclamation point come up with check engine light and other yellow warning lights last Sunday and the AC went out along with the cruise control. Since it was Sunday many Toyota dealerships were closed. I drove two counties south to get to an open dealership and they said my Hybrid Water Pump was bad. I had them replace it and it cost me an arm and leg! They have a new building and I guess they have to recoup their investment plus it was Sunday too! This just motivates me more to invest in a scan tool and learn more about how to fix these myself! This is the first time I've had this problem so I had no idea what it was? I just bought a slow charger for my 12v battery since I've gone through 4 of them in 11 years. I just put in a replacement of a 4 year battery that lasted only 23 months. My Prius seems to eat these 12v batteries! I also invested into some new spark plugs and two torque wrenches so that when I get to 150,000 miles I'll change them out myself. The quote I got to get the plugs changed at my local Tires Plus was $150. Too rich for me!
Super video thanks for sharing 👍👍👍
oh my god. I know this is 5 years old but i hope i can still monitor my hybrid this way, i've been searching everywhere.
The old cells are still partially good so can they be repurposed for mabye a power wall
Thanks for this video
I just bought a 08 Prius about 2 wks ago and so far I absolutely love it...I do believe I made a wise choice
dorothy edwards how’s it running now
Hows It been treating you
Thank you so much for your vidy
Good video, any Bluetooth adapter would work? Even with AP200 Autel but just to have the app you mentioned? Thank you.
Thanks Alot ..
I have been learning how these nimh batteries work when they are at low capacity, its best to put the cells on a trickle charger for a straight week at 100 miliamp charge at 3 volts above cell voltage. This will de-sulfate the battery cell and then when its charged you will take a battery load tester for lead acids and load the cell down for a full minute and check the amps as it trickles down, you should see with a good cell do 100 amps and slowly fall if it does not do 100amps or base capacity put it back on the trickle charger at 200ma and redo the load test. Once the battery is fully restored it will not off gas or heat when discharging like it was before but it will only give back 80 percent of capacity. The problem faced with hybrid batteries is that they charge the center of the battery capacity and they never get a full absorption charge. So from time to time take your hybrid on a 100 mile road trip on the interstate and do some really hard driving it will refresh the cells.
NiMH batteries don't work the same way as a Lead Acid but they are recovered in the same way - they don't "sulfate" per se but they do have what's known as "memory". In other words, if not used enough they'll wear out more quickly.
Mine frequently reach full around my city (lots of hills). I guess I could run them down too if it mattered by driving around in EV mode
How many miles did your Prius have when this video was made and at what mileage do the Prius batteries tend to fail?
My battery voltages all show up as 16+ volts but have code p0a80. What do I do next?
Hello again ... greetings when changing the inverter, do you have to program? It has to be the same part number ... example my car is 2007 do I fit a 2008 Prius?
Thanks for the video very informative, what BLUETOOTH WIRELESS ADAPTER works best for the Torque pro app? Do you have a link? TY
Thank you
May I know please which car scanner did you use for testing the 14 batteries voltage block modules (the health of the batteries) for Toyota Prius 2010.and which app is for iPhone, please.
if it were in california, 10 years or 150K miles on hybrid battery - it's the California law!
PZEV sold in California have a mandated battery warranty period of 10 years/150,000 miles. ... **Original owners; secondary owners receive 10 year/100,000 mile warranty.Feb 22, 2016
Corroded bus bars prove that resistance is not futile. Now I know. Thank you.
Be nice to see you join our" I love my prius " group on Facebook.
Which odb2 you used I have onniva it not connecting with torque pro app.
Note at 7:36 that the ICE stopped running yet the battery bar kept going up until 7:55, which is also a sign that the battery is failing as some of the modules voltage go up even when they are not being charged.
have the app and a blue tooth obd 2 scanner but how do I get it to show the batteries like your? Thank you
Thanks a lot, you may have solved my recent list of weird events, like sudden triangle, power loss, etc. ! Golden video what can I say. Is it at all possible to continue to drive with a bad battery, I wonder.
Marc Van Gastel I believe the car can “run” by using the regular battery. Not sure how it’s bypassed or disconnected.
I couldn't get Torque-Pro to grab the PIDs ("Press ENTER" (Where is Enter?) so I used Dr. Prius. Most important is Internal Resistance. That's where the blockage is. Most Prius owners don't know that if you take all 28 modules to your Toyota dealer parts dept, you can exchange for 28 New Panasonic modules for $1950. For some, this is better than playing "Whack-A-Mole".
Thank you that’s helped 😊
I’m thinking of getting a 2010 with 110,000 miles or a corolla the only thing that concerns me with the prius is if the battery or maintenance is expensive to fix. Do you think it’s worth it?
Please answer my question if you can. I have a 2011 Chevy Silverado 1500 hybrid I want to change 2 modules. What modules do you recommend?. I hear some shops are using new generation modules. Can I use any module?
So, I sprung $5 for Torque Pro app, added dials for my traction battery cells. There are 14 readouts, all within 1/10 volt of each other. I'm pleased as punch. '05 Prius, 110,000 miles. Original brake linings, too.

how to get TORQUE Pro display battery voltages by module? which version of torque pro are you using? Mine does not have this information....
I Installed window vents to keep the heat out in summer just leave each window down 3/8 of an inch to keep interior temperatures from reaching 120 degrees in summer!
I went through most of the indicators mentioned in this video and recently bought a remanufactured battery.
How much and do you like it? Notice a difference?
which scanner is that? i have one which does not show blocks on my 2005 Prius. please help me to find the right wireless scanner which can work with torque app. Thank you
Can you please explain how to use that app? I am about to buy a 2006 Prius with 184,000 miles. Is it worth it? How can I check the batteries before I buy it?
Did you end up finding out how to test it? I'm test driving an 08 gs450h lexus. Hope to bring it home. Just need to test the hybrid battery
@@modess0128 Unfortunately no, I am not well versed in the mechanic area, and I never received a message back from the creator so i just bargained it down to a lower price
Ms. Kim 195,000 07 I think my battery is going bad
@Ms. Kim Hi Ms. Kim can you tell me know where you replaced your battery?
@@MilesSpearman and what had happened ever since? I'm genuinely curious to hear/know your story :)
How long can u drive after all dash lights come on? Does hybrid battery need replacing right away or can we drive a few thousand miles?
Why, didn't mention the Year and Mileage, at what milage did this first indicate a problem. Otherwise, a great vid.
Hello, sir thank you very much for educating us, I have a question I am bought iPhone now and want to download Troque Pro but can not find it in the apple store any suggestions, please?
Hi, Could you please send the link to the battery check app? and would it still work on Lexus 400H
@CtrlAltDefeatTV I too have Torque Pro, how did you get it to read the individual modules voltage?
You need to either install a set of custom PIDs, or add certain PIDs manually. Google for "Toyota Prius Custom PIDs OBD2"
I think that Torque-Pro needs to be redesigned to grab the PIDs. No way I could figure it out with all the PIDs to choose from so I installed Dr. Prius instead. It says "Press Enter" to grab the PID but I could not find "Enter" on my Samsung phone or my Samsung Tab A. Frustrating.
@@amazoidal did Dr PIDS work?
Yes, Dr. Prius PIDs are easy to use. Never could get Torque Pro to PID.
is there a way to trigger the HV battery fan to run at all times and not when the battery temps reach around 100 degrees.
OBD2 apps: There is no "Apple equivalent" - Apple's devices don't support the Bluetooth profile that is required. Can't use an iPhone for this (unless you have a WiFi-OBD2 dongle, but those are expensive).
As for the error codes: A very low (less than 10V measured without load) 12V battery can also cause the red triangle, VSC light and other errors. Check that before you go buying HV-battery modules or have it replaced entirely (the latter is probably better in the long run).
Thanks Bro
..What can be done...to keep maintaining the battery?
I actually had my HV battery kick off where it was just the engine running revving up to 5000 rpms. I had to pull over like 30 times to not be stranded 5 hours from home. My kept running and i cracked the back window. Temps were 55-43 as the evening came. Which i think helped alot😳. Very weird you dont get the triangle of death. This must be limp mode for a Prius😆
Hey I really enjoyed the video and took your recommendation to get Torque Pro and a working OBDII adapter. My issue is I can't find the meter your using to check the module battery levels. Can you describe to me how to find this meter? I really need to get this battery repaired. I know its failing just need to know what modules.
You need the prius extended pids for torque to work. Search on internet or juts download Dr. Prius app
but what should the Voltage of a normal cell be during that AC on and the engine off test ? what is considered low voltage for this king of test ?
Helpful content, thanks! I'm going to test a 2017 Prius C with 117K miles tomorrow and I wish I had that app and the reader, but at least I know to listen for the vent and to watch the voltage animation while accelerating. If you have any other quick indicators I could look for in a test drive, please share! Lastly, I'm new to this whole Prius world, is it a fairly safe bet to buy one over 110K miles (one owner, clean carfax)? Thanks again!
110k is the perfect time to buy one and drive till 300k!
This is waaay after you posted the video, but I'll give it a try... I just test drove a 2006 Prius, and the battery on the SOC screen is gray. No purple, blue, or green. And although it shows power going to/from the battery the level does not change. What is this about and how is it fixed? Is it an expensive repair? I've seen this on another car I test drove, too. TIA
At what sort of stage of use do these batteries start not performing so well ? I have just bought a 2014 Toyota Harrier Hybrid 2.5 litre with 65000kms on the clock , as Toyota covers the battery for 100,000kms im not too worried but would like to see that its still running optimally , what is the app called you use ?
Thank you for the video, I have a 2002, every once in a while the engine revs up and the transmission will not pull and I have to pull to the side of the road and restart it, could this be a possible battery problem? I do have the triangle on.
Is it normal for the charge to deplete overnight? When I start mine up after letting it sit even for a few hours, it is kind of sluggish and the battery bar shows half full and depletes to one bar by the time I get to the end of my street. It charges back up as I drive after that though.
Really great video, btw. Didn't realize you could monitor the batteries like that. Will have to give it a try.
That is becuase it is a cold start. It uses less power from the engine and takes all from the battery. When you start it and still in park hit the gas pedal and the engine will start. Give it half a minute and you are good to go.
2012 Hyundai sonata with hybrid battery issues I check the voltage on the battery cell and the bolt is right but I'ma still wonder is the battery that is damaged or is something else? Thank you
