I bought this after market replacement battery for my Canon S200 as a back up to the orignal battery I got with the camera. I had hoped that I could use it in the field to swap out batteries when I took lots of shots and used up the battery charge.It worked for a while, but now the battery won't hold a charge, whereas the original Canon manufactured battery is still going strong. It holds a charge just fine. Pay the price and buy the original, and stay away from these knock offs.
