Easiest Way to revive a totally dead rechargeable power tool drill battery. Forget the other methods of bringing old batteries back. All you need is a charger, the battery and a few seconds. Works with most batteries. I gave this suggestion years ago on an older video where the guy used some wires to get the battery to charge. I noticed every time I put the battery in the charger the little charging led light would light up for a split second. So I thought it might be slightly charging the battery every time I did that. I was right and it's worked every time since on numerous batteries and battery packs. Thanks for checking it out.
