Problem with old battery packs
Ive got a few old battery packs here that im trying to get back into good working condition so I can use them for bahsing.
Ive been woring on them for a while now and have made some progress, the packs started out holding about 300mah and now they are holding closer to 1000mah, their rated capacities are 1900mah, 1700mah, and 2400mah.
The problem im having is voltage wise the packs are getting a full charge (all peak out at around 8.3 volts) so my charger apperently thinks the packs are done and shuts them off. Its like the packs are charging up fine but arent holding their capacity.
Any way to get them to hold their full capacity again? Ive tried slow charging but that seems to work worse than fast charging. Ive tried overcharging them on a timed charger but that doesnt seem to be helping, ive tried overdisharging them but that doesnt seem to be helping either.
Also how low (voltage wise) should I disharge them to? my good charger stops them at about 5 volts which I guess is about right, but I dont know....
If I cant fix them then its no big deal, ill just buy some new packs.
