A battery''s energy capacity can be calculated by multiplying its voltage (V) by its nominal capacity (Ah) and the result will be in Wh/kWh. If you have a 100Ah 12V battery, then the Wh it has can be calculated as 100Ah x 12V = 1200Wh or 1.2kWh. Note that Watt-hours (Wh) = energy capacity, while ampere-hours (Ah) = charge capacity.
