The mAh stands for milli Ampere hour or milli Amp hour. It’s the measure of a battery’s energy storage capacity. Imagine your battery as a fuel tank in a car, the mAh is the measure of how much fuel the battery can hold. The higher mAh rating the more fuel the battery can store inside. A higher number means that the battery can store more energy, so it has a higher capacity. Of course, this also means longer battery life for a given usage.
