What Does mAh Stand For

The letters “mAh” stand for milliampere hours – it is how a battery’s energy storage capacity is measured. This also tells us how many electrical currents are released in an hour.

m = milli = 1/1000
A = ampere, a unit of electrical current (usually shortened to “amp”)
h = hour
Therefore mAh means 1/1000 of an ampere for an hour. It is equal to 3.6 coulombs.
