Actually, Amazon do give the mAh spec,
This review is from: Canon NB-4L Battery Pack (Accessory)
A couple of reviewers have marked this product down on the basis that Amazon don't provide the mAh specification. They do, they just needed to click on 'see more technical details'. Also, its on the product image so if you enlarge it you can see its 760mAh. Felt I should point this out in case it was off-putting to potential purchasers.
There are so many non-Canon batteries available on so many internet sites, I feel it is better to spend a bit more and buy one carrying the Canon name from a trusted seller, otherwise you have the hassle of returning, like I did recently with a memory card that didn't match the image shown.
