Full Form of mAh in battery

In the context of batteries, "mAh" stands for milliampere-hour. It is a unit of measurement used to describe the capacity of a battery to store electric charge. Specifically, it indicates how much electrical charge a battery can deliver over one hour of continuous use, assuming a constant current flow of one milliampere (1 mA). The higher the mAh rating of a battery, the longer it can power a device before needing to be recharged or replaced.
