Query: Good, when it works correctly

I needed a new battery for my 5-year-old Canon ELPH camera that I was looking to replace, so I didn't want to spend too much. This worked about as long as the original battery did after being fully charged. My main complaint is that I get intermittent warnings to replace the battery even when it has just been charged ... or I get a message telling me to insert a battery when one is already in the camera. So there is some sort of miscommunication but the battery does hold a charge - it is just very annoying to receive an error message while trying to capture a shot.
