Revive your dead laptop battery for free: this works

My Fujitsu's battery had no charge and would not take a charge, and I was thinking about how to recycle it when I had a brainstorm. A long time ago, you had to completely kill the battery, then recharge it, in order to make it last. Why not stick the battery in the deep freeze (not the refrigerator's freezer, which is not as cold) for a while, then see if it will start taking a charge? So I did, and guess what: the battery started charging again, and works again. It only charges up to 95%, but that is still a significant life. It doesn't last that many days before you have to repeat the deep freeze process, but it works each time. I don't know yet how many times the battery life can be extended this way, but I was surprised that it worked once, let alone several times. Wrap the battery in a towel and put the whole thing inside a plastic bag, let it sit in the deep freeze for a couple of days, and when you take it out of the deep freeze, let it warm up to room temperature inside the towel just to make sure that moisture doesn't start messing anything up.
