Comments about Lenmar� Camera Battery; 3.7V, Fits Canon PowerShot SD1100 IS, SD1000, SD970 IS, SD960 IS, SD780 IS:
I bought two of the Lenmar batteries, charged them, and ran each through a full charge-to-discharge cycle before recharging them. Per the instructions, the initial charge didn't last as long as one might expect. Now that they've been through the first cycle, it will be interesting to see how well they perform.
Bottom Line Yes, I would recommend this to a friend
