How to calculate energy stored in battery

In summary, the energy stored in a battery is measured in watt-hours (Wh) or joules (J), and can be calculated by multiplying its voltage by its capacity in ampere-hours (Ah). Other factors that can affect the energy stored in a battery include temperature, age, and usage patterns, and the energy stored can also be converted to other units such as kilowatt-hours (kWh) or kilojoules (kJ). It is important to refer to the specific battery's specifications for accurate calculations.

If you know the battery voltage V, and the battery capacity AH in amp-hours, the energy stored by the battery in Joules is just E = V*AH*3600, where the 3600 is the number of seconds in an hour.May 18, 2014
