Query: Great camera, very poor battery life

I have had my Dimage for about a year now. I used to use it often with the marine case while I was out kayaking. The image quality, features, and responsiveness of the camera are outstanding. However, the battery life on this camera is horrible! I think I have spent more in batteries then I did for the camera itself. Even with the flash suppressed and a new, charged battery, 20-30 shoots is all I can get. As another reviewer mentioned, it seems to be getting worse with age, making me suspect it is something in the camera circuits.
