I have more than a few of these batteries laying around that haven't been used in about 6 months and I was more than a little disappointed that most wont even hold a charge now The only ones that work are the two original Canon batteries (the others are from Opteka, SterlingTek and e-bay). Now I know why Canon batteries cost more (they are well worth it in my book now).
Anyway, I've been putting a few of these batteries on my Canon HV30, playing a tape until it auto-shuts off then putting them on the charger. Repeated this about 10 times and nada. They still only last about 5 minutes on the camcorder while the Canon batteries last about 35 minutes. Anyone know any tips, tricks or methods? Or am I just SOL?
