Title: Loses voltage quickly
Review: Bought this to have a spare battery for my V550 on vacation and it does not work as well as the OEM battery. Specifically, when trying to take multiple photos a few seconds apart, the battery quickly drains and needs to rest between shots. The low battery warning comes on, and if you keep using the camera, it will shut down due to insufficient battery power. Let it rest for a few minutes and you're ready to take pictures again. The total number of pictures I could take with this battery was similar to the OEM, but the lag and the frustration of the camera shutting off was not worth the savings (~$5) when I bought this battery.
