Tried jump-start method first, didn't work. Just did this and it worked perfectly. Thanks

tried the jump-start, fail☹ took apart the battery pack and w/out de-soldering, prying up the small spot welds on (2) of the batteries(not a pretty sight) then using a small flat head screwdriver, pushed caps... "pop" success! my 11month old 20v-battery in now charging again! Thank you!, Thank you!

Knowledge is the key. Much appreciated

You are a genius! just subscribed. I got jump start to work a couple of times

Had the same problem and I was able to reset it without de soldering. I used a very small flat head and yeah it worked. Thanks man. Saved me $100

GREAT!!! Just fixed 8 Batteries without taking the cells out! Life saver!

Glad the algorithm made your video pop up in my feed. Tried jumpstarting a dead dewalt battery and it didn't do anything. Figured I'd have to buy and replace cells but I'm going to check for this first. Thanks!

Great film thank you for the information, much appreciated. 👍👍👍

Awesome job. Thanks, real informative and a way to help the ppl🇺🇸🇺🇸👍🏼

Thank you for this video. Jumpstart did not work. Was able to reset it as well and now it charges just fine. Two cells I heard a "pop" noise when pushing down on the cap. Did not have to de solder. Thanks again!

This trick worked for me one time. The 2Ah packs are forced to work too hard and that's why they get so hot. I replaced my 2Ah packs with the 4 Ah packs and haven't had any problems since. I thought about repairing my 2Ah packs but (decent) cells would cost more than buying a new 2 Ah pack. Marketing. 🙂

Great fix thank you

You're ingenious thank you I have often wondered if there's a way of doing this as RC car batteries do the same thing but there's no reset button on those you have to changed the cell

I tried the "jump-start" and all it did was make my Makita battery pack hot. Luckily I haven't thrown it out yet so I'll give this a shot and see if it'll fix the problem. Thanks for the tip.

Great clip, and i dont say that often

This worked for me. My issue seemed to be that I added the DCB094 USB charger to a brand new Dewalt 6mAh battery for my wife to use a USB LED light. I believe it discharged so slowly that it snuck past any electronic stop and made a cell "pop." Be careful about very long-term low level power drains! I was surprised that I didn't need to remove all the cell connections to test voltage on each cell. I tested each of the eight cells. Each gave 3.66V then two gave over 4.5V - I did the manual reset on one and it started charging again. The charger stops at two of three lights, but hopefully all the voltages settle and I can get to a full charge after using and charging the battery over time. SUPER HELPFUL!!

Great Hack Sir. I will try that on a 12V dewalt post battery no longer available. Jump start did not work. Likely not used for years perhaps decade. NiCad. I thought those connections had to be done with spot welder. Becareful when soldering. Minimum heat. Battery inside a pipe.

Man you saved me !!

Wow super ill look into this I did run my pack down I bet it did pop

I love this and I especially enjoyed the suspense of knowing if it was going to work along with you 😅. My question is, if the cell popped once before, is it likely that it pops again in the future? I have a 2a dewalt battery that only worked a couple times, I’ll have to try this and post my results. I’m curious as to how it works out for you.

So far it has worked fine ever since. I was working the battery hard (it was quite warm) when it popped. I suspect I pulled too many amps from it. It has been worked normally since without issue.

Thanks for video.I have a bunch of dead cells . I think dewalt are junk but I am stuck with them

I wonder if that would work for Craftsman batteries. Thanks for taking the time to do this video though.

@@Tree-ations Yeah, it's a Craftsman V60. Two of the 20 volt packs seem to be fine, but one them, if I checked it right, appears to be dead. I tried to jump it with two other fully charged batteries, one 18 volt "Warrior" brand and the other a Craftsman V20. It didn't seem to work though. I'll probably try your method next. If I do, I'll post my results.

never heard of the CID most if not all flat cell 18650 are unproctected, so i assume those are more expensive because they have those features. Most button tops have protection

How to unsolder battery from assembly?

be careful doing this. if your insulation on the side of the battery is damaged, you can short the battery and it will vent. I learned this the hard way working with these types of cells in another capacity.

@Richard Conrad that would indeed be a vent. You are correct, that battery is toast.

Gotta try this with a 60v that I have that will only jump start to 14v. Will not charge beyond that. I'm assuming only 4 cells are functioning.

cool!

I'll try,still feedback u soon

So, if one of the cells is bad but unable to be reset or "fixed" is it possible to purchase a replacement cell so the whole battery doesn't go to waste?

yep, i was given a WORTH 80v battery pack. i took it apart and it had one bad cell. I used one of them to replace a garbage cell in my BAUER 1/4in impact 18v battery. Its back up and running. Nice thing about the giant battery packs is i took mine apart in a way that kept most cells attached together at one end. " i dont have a spot welder" so made it easier to build 2S battery packs for rc cars as well.

When I did the video I didn’t know what was wrong so took the batter out. Now that I know about that safety reset cap I wouldn’t remove the battery. You can just reach in with the cell still in the pack. Give it a try, you’ll see what I mean. If you read the other comments, other people have found this works well.

ρяσмσѕм ?

vslusble video.

While this "works" it essentially disables the safety mechanism. If whatever caused the cell to vent the first time happens again it can catch fire or explode (right next to 4 other cells). If you battery pack catches fire while in your garage and burns your house down your insurance company will use this video evidence to deny coverage. Replacing the bad cell with a new one would have cost you a few bucks.

Cool….is it possible to push that cap down without desoldering the end ?
