What does it mean on a rechargeable battery for a digital camera when it says "1050mAh" or "800Ah"?
Posted on Jan 28, 2010 under Digital news and reports |Does the higher number on a rechargeable (Li-ion) battery mean it will last longer that one with a lower number? Please explain, as I want to buy a generic rechargeable battery for my Canon G10 digital camera that’s a lot cheaper that the Canon version.
The trouble is that the more expensive Canon battery has "1050Ah" printed on it, while the generic has "800Ah" (or something like that).

mAh mean milliamp hour and Ah means amp hour. This rating of a battery which indicates the current battery can supply in hour. So the higher the rating longer the battery life before recharging.
Think of this is the fuel cell of the battery. Higher the number, more fuel it can store and longer it will last.

All the batteries you mention read mAh, milliamp hour. The generic does not have the capacity of the Canon model, so all else being equal, it would only last about 80% as long as the Canon battery.
An 800 amp hour battery would be as big as a van.

You are correct, higher maH lasts longer. They take longer to charge too and yes, they cost more too.

Higher ratings means more photos per charge.
Generic batteries come in different ratings. You just happened to find one at a low rating.
Below is a link to another generic replacement fot your Canon NB-7L battery. This one is rated 1500mah (higher than your Canon battery) and at $12 still costs less than the Canon battery. User reviews are very good for this generic.
Higher ratings wont harm your camera they will just give more shots per charge.
