Hi, I have a Sony Cybershot

Hi,

I have a Sony Cybershot 3MP camera. it has been working fine for just over a year. However, when i try to turn it on it says he battery is low and then switches off. Or it will work for about to minutes before blinking out without even closing the aperture and zoom lens. I have tried charging the existing batteries and i've bought new ones and madesure they a fully charged. I get the same problem...

Can anyone help me, or can you tell me what's wrong with it???
