RE: battery problems

If you run them down too much they become trash. Don't know any revival tricks once they are below 3v per cell.

Putting a battery in the refrigirator won't revive a battery. That technique is used to lengthen the shelf life of a battery, not revive them. And it's only about 5%, so it's really not worth the effort.

If the battery you're speaking of is a Lipo battery, you could put it on a Nicad charger for a few minutes, under supervision. Then put it on the lipo charger. (As long as the voltage ratings are the same for both chargers.)
