I had functionality issues with certain buttons on the camera. A new battery fixed this and I have not had an issue since.
Wow.
That's an interesting effect!
Unfortunately the camera is already with the Canon people. I showed them it malfunctioning and they saw it fail. They then gave me the battery back and took the camera away.
If it comes back with a "could not reproduce" note then I will try another battery.
Thanks for the fun fact.
