DIY: Revive Dead NiCd Battery From Cordless Power Tools

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.

    the only trick with li-ion - is to take a part and check cell by cell to find witch one is bad and replace it. Some times some electronics components are failing too..
