Your camera uses standard alkaline AA batteries or rechargable NiMH batteries.

There are a number of companies that sell NiMH AA batteries and chargers. Including all of the big battery companies.

I have had good luck with several different brands.

Cannon does not make batteries so they also buy them from someone else.

What is mah?:

mAh stands for Milliamp Hour, a technical term for how much power a particular battery will hold. Digital camera batteries with higher mAh values last longer without requiring a recharge, allowing you to take more photographs before you have to recharge your batteries.

It is recommended when placing batteries in a digital camera that their mAh values match. i.e. don't mix an 1800 with 2300s. Have them all the same.
