watt-hour

The power utilization for one hour measured in watts. Abbreviated "Wh," it is widely used to rate how long it takes for a battery to discharge. For smaller batteries, a milliwatt-hour (mWh) rating is used. For example, a 500 mWh battery means it will release 500 watts at a specific voltage for one hour before it is discharged. See ampere-hour and watt.
