Canon 300D and Battery Problem

[greekspy2001]

Hi

Wondered if anyone else is getting the same....

Whilst operating the camera after a while the stops with a flat battery. No problem change the battery and carry on. However when I get home and start to charge tha battery it is not flat by a long way. If I put the battery back in the camera with out further charge the camera reports there is a lot of charge left.

Have a 30D aswell and will check with that over next few outings.

But anyone have any ideas?

Thanks

Graham
