Is it possible to recharge old, long-dead, camcorder batteries?
I am wondering of there is a method for revitalizing old camcorder batteries which refuse to charge.
I know that certain camcorder battery chargers used to come with a "refresh" button. However, the chargers that came with my batteries lack this feature.
I believe that most of the batteries are Ni-Cd's. However, one of them is lead-acid.
The lead-acid battery is from a VERY old camera, one in which you placed the camera on your shoulder, and slung a VHS VCR from the other. When you were done recording, you would then take the VCR and plug it into the a matching TV tuner. This would charge the battery.
Any ideas that would help me get some charge into these batteries would be appreciated.
