I own a Sharp v le750 that is 3-4 years old. About a year ago I noticed the battery just wasn't holding a charge. It would last maybe 20 minutes and never show a full charge on the meter. I bought a new battery and noticed the same thing even with it. So I bought a new charger - same trouble. I've followed all of the instructions and charged the battery fully before using. The new charger even has a 'drain' feature to avoid battry 'memory'. Is the camera ready for thejunk heap, are my expectations too high, or can it be fixed?
