I contacted Canon about this problem, and didn't find the answer very useful, so I'm posting it here to see if anyone else has encountered this problem:
I have two batteries, one of which is a Canon, the other a Merkury - neither are more than a year old. I also have two chargers manufactured by Canon. The problem is with both chargers/batteries - ie I can switch which battery is in which charger and encounter the same problem. Essentially, when I plug a battery in to charge, the light will eventually turn green, but if I remove the battery and then immediatly re-insert it into the charger, the light on the charger will become red. Also, when I insert both batteries into the camera, the camera usually immediatly tells me to charge the battery pack. However, sometimes I can fix this problem (temporarily - enough time to take one picture) by opening the battery compartment and then closing it again. Canon suggested I clean the terminals (which I did) and said outside of that it was likely a camera problem. Are they correct, or has anyone fixed this problem by getting a new charger or battery? I am (obviously) not very camera savvy so any help would be appreciated. Thanks!
