Understanding Watt-Hours: A Guide to Energy Storage Capacity

A watt-hour (Wh) is a unit of energy, equivalent to 1 watt of power over a period of 1 hour. It is often used to express the capacity of batteries and other energy storage devices. For example, a battery with a capacity of 5000 mAh (milliampere-hours) at 5 volts would have an energy capacity of 25 Wh (5 x 5000 = 25,000 milliwatt-hours).
