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. |

The BA-8180/U is a 12/24 Volt, 800 watt-hour, 56ah primary (non rechargeable) zinc-air battery pack. But to measure much smaller electricity use, such as a light bulb or hair dryer, it's more practical to use the unit watt-hour. Analysis of meters by type- watt-hour meters: electromechanical/solid state, gas flowmeters: mechanical/turbine/orifice/ultrasonic, water flowmeters mechanical (volumetric/velocimetric)/electromagnetic/ultrasonic |
