Summary: Can't Beat The Real Thing

Comment: I bought this battery after 3 of the cheaper (generic) batteries ran down after only a few pictures, one of those batteries swelled up and wouldn't come out of my camera. I'll not buy another generic battery for anything.

Summary: camera battery

Comment: Although I have not had this battery for a long time yet, I find using the canon batteries do last longer than those that are just compatible with my camera. I haven't given it 5 stars because the real test will come with time.

Summary: Nothing like OEM batteries

Comment: Don't skimp when getting new batteries for your Powershot.
You will end up paying more for aftermarket batteries because you will have to buy twice as many because they only have half (maybe less) the life of these.

Summary: New battery for the camera

Comment: I purchased a new battery pack right before our trip to Alaska. We did not have any problems and even forgot to charge it one night and it still performed all the next day. This is the second battery I have bought for my S300. The first Canon battery pack lasted 5 years (it came with the camera), the second battery (first replacement) - a Maxwell - lasted only one year. I will only buy a Canon battery pack from now on. The life span is much longer. The Canon Battery Pack cost a little more but it is worth it in the long run.

Summary: Exact replacement

Comment: This is a perfect replacement for the original battery that came with my Canon S410 digital camera. After 3 years of heavy use (we have two lovely grand daughters, do I need to say more?) the original battery was not holding its charge as long, so we needed a replacement. New battery charged right up and is working as long as original used to. Very fast shipping from Amazon and good order notifications and tracking. Although this cost more than knock offs, for the fit, function and peace of mind this is a good purchase.
