The original Canon batteries perform noticably better than the DigiPower battery, and they also stay fairly cool, as opposed to the DigiPower battery that gets dangerously hot during operation.

I've had no problems running my Canon batteries, but the capacity is not all that impressive - hence the 3 batteries. An absolute minimum here would be two batteries for your camera.

On my S200 with the LCS screen on, I can get somewhere between 75 and 150 pictures out of one fully charged battery. With the LCD screen off (only a 2 second preview after each picture), I can get around 200 (sometimes a few more) pictures out of one fully charged battery.

I've been using my newest battery for about 10 months, and so far I haven't noticed any decrease in capacity. It appears to hold its charge very well for weeks at a time.

I would probably have given it a 2 star rating if I took the general battery capacity into consideration, but since you don't have any real options to this general battery type, I'll give it an overall 5 star rating. It performs better than other brands for my camera, and I've been very happy with it in all aspects.

I would also recommend that you to buy this battery and not a Canon equivalent from another manufacturer. This battery's worth the extra money!!!

Excellent Price!!! (Rating: 5.00)
Review : Excellent price!!! I have used this battery as my "Main" battery and saved the original as a spare. THIS battery has had ZERO defects, as I have used my new camera quite a bit since recieving it and have charged it twice since recieving it. (It takes FULL charge and lasts the expected amount before recharge.)Not bad for the price!!!

Great Battery -- But DON'T buy generic!! (Rating: 5.00)
Review : We have had our Canon S400 for about 4 months & it has been wonderful -- as well as the Canon battery. The charge lasts for a pretty long time. We bought a generic battery (from an individual seller off this site) for a backup. It died in a little over a month. Don't bother trying to save money - just get the real thing (which this is).
