The correct unit for measuring energy capacity of a battery product is called watt-hours. Watt-hours signifies that a battery can supply an amount of watts for an hour. For example, a 60 watt-hour battery can power a 60 watt light bulb for an hour. The same battery would run a 5W phone for 12 hours and power a 1W LED light bulb for 60 hours.
An electrical watt is a measure of power. A 40 watt light bulb uses  40 watts of electrical power. It has a relative measure of twice  the light output of a 20 watt bulb and â¦ one half the output of an 80  watt bulb.   A 40 watt bulb uses 40 Joules of energy each second, or 40  watt-hours of energy each hour.In 1000 hours it uses 40  kilowatt-hours or Units of electrical energy.t has a relative measure of twice  the light output of a 20 watt bulb and â¦ one half the output of an 80  watt bulb.
