A unit for measuring electric power over time. mAh is commonly used to describe the total amount of energy a battery can store.
A higher mAh rating means the battery can power a device that consumes more power and/or for a longer amount of time. For example, a battery rated at 1500 mAh can power a device drawing 100 milliamps for 15 hours, or a device drawing 150 milliamps for 10 hours.
Yeah, pretty much. Basically, it'll deliver a total of x milliAmps for 1 hour, or twice that for half an hour, etc etc. It's not really that simple, since the mAh rating is usually for a fairly low draw; if you're using the device at its highest power draw, you may be using twice the amperage and get closer to 1/3 the time.
