My digital camera is a Canon Powershot A530. I use Duracell’s batteries for it, but after I take about 20 pictures, it starts to act up and says to change the batteries, and will take maybe one picture, then shut off on its own. I’ve gathered that maybe the batteries I use are not compatible with my camera, but I don’t know which batteries are. If you happen to know which battery works well with this kind of camera, well please answer. :) Thanks.

Are you using rechargeables? I have a Powershot A540 and I use the Sanyo eneloop AAs. They come charged and stay charged out of the camera, and seem to last a long time in the camera, too. Regular batteries do not have enough power for a digital camera. Buy some rechargeables and a charger. I think you will have better luck. Just don’t spend a lot of time looking at the pictures you have already taken. That will run the batteries down fast.
