What is 4800mAh?

Answer 1

A battery rating of 4400 mAh means that the battery can nominally produce 550 mA for 8 hours.

Even though it would seem that the battery will produce 4400 mA for 1 hour, it will not actually last that long. By convention, current-time ratings on batteries are normalized to an 8 hour rating.

Answer 2

4800 Milli Amps an Hour / 4.8 Amps/hour - means that your electronic device will spend that amount of electricity.

Answer 3

it means the laptop battery can produce 4400 milliampere per hour, so if your laptop 1 milliampere per hour so the battery will last for 4400 hours.
