Query: Great Value!

The battery that came with my Canon SX230 HS was an 1120mAh. These are rated 1400mAh. Based on that they should last even longer without recharging. I have not bothered to do a comparison between how long the Canon battery lasts versus this one, but this one definitely lasts a long time. Unhreal price. I'm very happy with this battery!
