Default How do you calculate the WHr of a battery?

Say I have a battery which is 10.8V and 4.0 AHr, how would I determine the WHr?

Not that simple, as the battery voltage is not linear with time as it discharges.

Well if you know how many watts a device uses... you could figure out how many hours the batteries would last.
