If we want to calculate how much energy – in other words, how many watt-hours – is stored in a battery, we need information about the electric charge in the battery. This value is commonly expressed in amp-hours – amps (units of electric current) multiplied by hours (units of time) – see the hours calculator.
As you might remember from our article on Ohm''s law, the power P of an electrical device is equal to voltage V multiplied by current I: As energy E is power P multiplied by time T, all we have to do to find the energy stored in a battery is to multiply both sides of the equation by time:
