ELB,

Thanks for the tip.

I have been walking away when my lithium batteries for my cordless drills need recharging in my garage.

I won't do that anymore...

Depends on what they're used for. This link is mostly about NiCd and NiMH batteries, but has some info on lithium batteries. Zapping doesn't work on lithiums. There is some useful information on the NiCd "memory" issue

Very good information in the link. Thanks for posting. :thumbs2:

While shopping for a new drill kit at Lowe's, I told a Lowe's employee that my old Craftsman drill batteries would no longer hold a charge and one battery was less than one year old, plus those batteries were very expensive. He said that not keeping the battery attached to the drill when stored would solve that problem. I have a DeWalt drill now, and I'm following his advice.

I have noticed that they sell fireproof bags/sacks for charging and storing Lithium batteries.
Maybe I will buy one. They have several brands on Amazon.
In one of the reviews the person says he puts his bag inside of a metal ammo can.
I have a couple of those. :lol:

I think you may be incorrect about NiMH batteries. NiMH batteries, as you can see by the chart maintain nearly the same voltage from 80% charge to 20% charge before they dramatically fall off. But I guess it's all in how one thinks about rolling down a hill :mrgreen:
