    Reviving old NiMh Batteries?

    I have about 6 packs from 2005-2008 of NiMh quality battery packs. Are there any procedures for resurrecting these? I realize they won't be as good as they were, just looking to maximize what I have. I have a Superbrain 959 charger BTW. Thanks.

    i wouldnt bother with trying to mess with them as if you dont charge them excatly as there suppose to they are very dangerous. i just left my old nimh pack alone now, i tried to trickle charge it for like 10hrs but didnt work only made the battery slighty warm which it shouldnt have been charging at only .2amps.

    you gotta cycle the packs meaning charge them at a low rate then discharge them and repeat this bumping up your charge rate little by little till your just a few amps bellow 1c (a 5000 shouldnt be charged over 4.5 amps... for example)
