What does the capacity rating mAh mean?
A. The capacity or energy storage of a battery is measured in milli Amp hour designated as mAh. For example, a 2300 mAh battery will last for one hour at a 2300 mA discharge rate. It is not a measure of battery strength. The higher the mAh rating the more energy it can store and the longer the battery can supply power to an electrical device at a given discharge rate.
