In this video I'll show you how to bring to life dead NiCd battery from cordless power tools.
Nicd batteries often die in such a way that they won't take a charge and have zero voltage. This usually means they're shorted out by crystal dendrite growth inside Nicd cells.
There's a method of bringing them back to life by zapping those shorted crystal dendrites away with too much current and voltage.

what is the cutoff voltage of a ni cd battery with 12V?
Thank you, this helped!
Will these batteries have a long life after such "restoration"?
could i do this with linked 9v batteries? or a ac to dc converter wall plug?
can you use ion lithium batteries in the older power tools that just use the regular nicads and I suspect you need a new charger as well? Hard to do if your battery case only fits a charger for the regular nicad. I suppose you would ned to charge with a different mean such as an alligator clip to the tool.
what if all the batteries are dead. Can you use anything else
make sure to upload the video of your house on fire after that thing blows up
any way to revive li ions?
I am confused. What powers the lipo balance charger? Sorry slow here.
I've been researching into fixing a car battery and found an awesome website at Jons Mender Guide (google it if you are interested)
That was pretty dag gone smart!!!
You can not be repair in the same way the old batteries. In most cases the battery is worn out and has a high internal resistance.
Zapping crystals eh? lol with such knowledge there's no need to buy anything new ever again! 😉
Yess! Finally someone with actual knowledge about to do the NiCd to lithium conversion. I have a cordless 18V drill sitting on shelf with no battery. Can't wait see how to do it properly 🙂
Great video. I just bought a drill on eBay that comes with NiCd battery, so it would be great to see the lithium conversion 🙂
Nice! I have a makita at home that has these batteries and is slowly loosing becoming unusable. Thanks for this, am going to give it a try!
