I have Canon D20 after 3-4 shots it shuts down. It shows that the battery is discharged. If I turn it off and take the battery out and replace it it will again take 3-4 shots.
I have used three different batteries that I know are good and charged.
I have the identical problem and cannot find the answer to this. I had the camera serviced and it didn't correct the problem.
wish I could find out the answer as this camera is not reliable to use....I have to keep a back up that is not nearly as good as quality but at least it will make an exposure. So disappointed in the Canon D20.
