If you rebuild a battery pack, and the battery gauge does not work properly or at all, with no power output, then you can usually correct the problem by disconnecting the NEG and/or POS tabbing for at least 1 minute. That usually corrects the issue. Thanks for watching!
I just referred this video to a CZcamsr in response to his comment. He left his electric mower battery in for 7 months and now it won't charge. The cells may have discharged so low that forcing a charge, like as done in the video he asked his question in, could make it explode. Maybe you'll get another subscriber.
Superb video. To the point and yet thorough.
Thanks for this video. i feel confident that i can do this correctly now.
and like others have said...that spot welder is super cool.
I watched this all the way through because I've seen others fail horribly trying to do this. A calm hand and a plan gets the job done 👍
Id been repairing these for years. Usually 1 or 2 cells will go out. Ive had good luck with capacity testing the others and replacing the bad cell with a like capacity. Great video!
*_Any recommendation(s) on a test tool for these 18650 (and other sizes) cells?_*
@@andyroid5028 Rolls Royce tester-charger : SkyRC MC3000 / better price lower perfs : Opus BT-C3100
Internal resistance (impedance) tester : YR1030, to compare with values on cells manufacturer's datasheets.
I'll bet you developed your interests and began asking questions at a very young age. Thanks for sharing your various discoveries.
Great how to video! I've got several battery packs that need repaired. Thanks again!
Glad you enjoyed the video! Looking forward to your next video
That little spot welder is very cool.
so cool
*_This is great information. Thanks brother!_*
Thanks
I’ve used old Dyson cells not large capacity but quality with a good draw capability . Ps Dyson boards give out long before their cells. 🏴🇺🇸🏴
I opened up a Dyson battery pack and tried to replace the cells, however the cells did not want to fit in the same space theirs were. Too tight. Should I try and remove the plastic jacket from the battery to get just that tiny bit more of space to wiggle in the batteries? (I expect the board is just fine, the motor runs a few seconds on the current batteries, and if I add an external power source I can let it run very long as the power is not drawn from the batteries anymore). I really like the Dyson cleaner and want to fox it, they are so robust!
@@deslomeslager some Dyson are 2170 some are 18650 . The from memory, second and third one in are “ glued “ in because of the temp sensor sitting in a v shaped recess ( below the board) potted in, some care and effort is needed to remove them , but can be done . In my opinion Dyson battery’s are only good for cells once they won’t work in Dyson 🥴
@@pollywollydo Thanks for telling me. As said, I managed to get them out just fine (18650), but the new ones I have got seem to be a very tiny bit thicker though they are original 18650 Samsungs. But I do can try and use a file to take away some of the plastic, and make the batteries fit.
@@deslomeslager removing the cells that are temp’ monitored will destroy the sensor which has 2 wires back into the board so if either of those are shot I wouldn’t bother otherwise give it a go 🌝🏴🇺🇸🏴
Great video to start off with. I am doing a ryobi but not the hp model and it doesn't have the same reset. I have the flash and can't reaet
Great video!
Glad you enjoyed it!
Does the order of resoldering the balancing wires matter? The pack doesn't seem to be working after replacing the cells. I have replaced cells in other brands without having any issues. I wonder if ryobi has some kind of minimum voltage protection.
great video,,i have lots of ryobi tools
Thanks for watching!
Nicely presented. What necessitates shorting those those two points to reset the battery pack? Wouldn't replacing the original cells already do that?
How did you discover the need to do that?
I hope my questions are not too confusing.
Regards and kudos to making the Earth a greener place by reducing throw away items and helping to save money.
When the battery voltage drops, or if the cells are removed, you usually need to reset the circuit. Thanks for watching
I’m curious do you know how to produce terra hertz frequency’s ??
0:50 Before replacing the cells, especially if it's not old, you should charge and discharge them individually, then recharge them all back to full. Then put it in the tool and run it for a while, then put it back on the charger till full. Do this 3 times.
Also, a lot of modern battery packs cannot be refurbished. They have custom chips on the board and will not function if the batteries are changed.
There's a way around those battery packs. All you have to do is apply voltage using a power supply unit to the battery positive and negative terminals before removing the cells. Then charge the new cells to match closely to the voltage of the PSU and install them. Once the new cells are installed, you remove the power supply and there should not be any issue with the battery pack.
That *_is_* a very nice battery pack design. The individual cell holders makes replacing cells much easier. Your battery spot welder link has a few selections. Which one do you use and do you recommend that one or another one, please? I've wanted a battery spot welder for a while. And do you have a link for the metal tabbing? I don't see it listed in the Description area. I see 0.1mm x 8.0mm in the video, but no other info. I think I'd spot weld a T instead of folding over, but that's me. It will use less tabbing. Another great one, Scott. Thanks
Look for the one that you saw in the video, it's in black on that page. I use the highest setting which is number four. You can also find the tabbing on that web page link.
@@electronicsNmore Thanks, Scott. I noticed the metal tabbing on the page and that yours comes with some. That should be plenty for the little I'll need it.
Interesting video, I always thought these batteries were sealed and not really serviceable. It just goes to show that if there's a will, there's a way. 👍👍👍 Someone would have to figure out how much work and investment they want to put into repairing these batteries if they're in good enough shape to repair. I like the spot welder. Do you use the spot welder for other things?
Spot welder is only used for creating battery packs. Thanks for watching!
Thank you for answering my question, and I really enjoy your channel. @@electronicsNmore
I was hoping you’d measure the old cells so we could see if it’s only a portion of them that went bad.
It's not worth changing only a couple of cells, so I didn't bother. Usually one or two are faulty.
@@electronicsNmore Yeah, but it’s good to know the usual failure mode and how many might be good cells to use in other things, like flashlights. Thanks!
u need to showe the new battery packs..they r different they ur 5 to 10 yr old pack.
also Ryobi uses high quality cells too
My battery pack was only 3 years old.
*_It's really annoying to know Ryobi (and other brands) could easily make these cells easier to access/swap but I understand the reason it's designed this way... but it doesnt mean I have to like the design. 😮😊👍🏼_*
They don't want anyone doing this operation. There are incredibly stupid people who will do incredibly stupid things and then blame and sue the company.
That must have taken you at lest an hour for everything.
Any thoughts on how to put a 18v ac adaptor instead of batteries? since I tried it on a dyson and didnt work. LOL
Only about 45 minutes
Tamper proof fasteners make me laugh. Tamper resistant would be a mildly better description or easy to remove if you have even the crap Iest of driver sets.
Tamper*
@@shawnd567 that’s the problem with dictation on the phone. I certainly know it’s tamper, but didn’t realize the phone took it as temper. 🤷
Ya... requiring a spot welder is where it fell apart for me. (Whose gonna buy all that stuff to rebuild one battery pack?) I don't have 10 cordless power tools that need the packs rebuilt.
The spot welders aren't that much money if you plan on rebuilding your battery packs well into the future
@@electronicsNmorewhat brand is this spot welder?
I hope you realize that there are different types of 18650 batteries, you can not only go by the current capacity! Power tools use high discharge current type batteries. Standard discharge batteries are used for lower current devices like laptops and typically have larger capacities. Standard batteries should not be used in power tools because the higher currents will shorten their service life.
Of course I realize
Really, most people don’t have time or tools to complete the battery pack. Just buy another OEM battery pack.
If you don’t have anything nice to say…
