Basically, I have a dead laptop battery that I tried charging by plugging it in for 3 weeks and would only get recognized and stay at 0%. I have it in my freezer in a bag, and if that won't work, can I microwave it for a few 2 second bursts? I heard that works, but I want to know if I can do it on a Ni-Cad ot Ni-Mh battery.
