Fix Dewalt Battery that won't charge (Try this after you try the 'jumpstart' fix)

If you've tried the jumpstart method and still have a dead battery, give this a try! It brought a totally dead battery back to life for me!

My issue was a popped CID (Current Interrupt Device) safety device. Manually resetting it allowed the battery to return to service.

Now that I know about this fix I wouldn't remove the cell which would turn this into a 2 min fix. You can check & reset the CIDs without removing the cells - you just have to open up the plastic case.

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

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!

Watched three videos that showed this method, you’re the only one that explained what it was and why, and that it might not work again after. Thanks and will give this a try!

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. 🙂

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!

Worked great…was able to reset without taking out individual cells using a small pick. Thank you! 🙌

This I fix about 10 old battery of Milwaukee's DeWalt Cobalt Craftsman's and several other batteries that worked on too

Knowledge is the key. Much appreciated

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!!

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!

The final fix attempt. Ty. For sharing this. It worked.

[cristimz]

This help me a lot.. thank you very very very... i search about each piece size price and its a bit expensive i tried this method and kaboooom its works

[dannyschacht]

I should've read the other post first...thanks again.

[dannyschacht]

excellent!! Can you reset the battery without un-solding it?

[alanhart]

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

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.

[gordbaker]

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.

[MrAngerthis]

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
