Casio battery problems?

I need to buy a new rechargeable battery for my Casio Exilim EX-Z8 camera as my current one has died. I have found a number that i could buy but they don’t have the same mAh number as my current battery. My current battery says it has 700mAh and others i have found range from 630mAh to 800mAh. I was wondering is it going to be compatible with my camera, it says on the sites it will but i just thought i would double check.

the higher the number
the longer it will hold a charge
