So we calculate the power capacity as Volts times Amps times hours equals capacity in Watt-Hours. You can use the numbers printed on a battery to calculate a number for its capacity in Wh if its not already there. Most of the time the Amp and the hour have already been multiplied so the equation is just Volts times Amp hour equals Watt hour.

A battery with a capacity of 1 amp-hour should be able to continuously supply current of 1 amp to a load for exactly 1 hour, or 2 amps for 1/2 hour, or 1/3 amp for 3 hours, etc., before becoming completely discharged. In an ideal battery, this relationship between continuous current and ...
Amp-Hours (Ah): Capacity of a Battery. Amp-hours (Ah) is a measure of a battery''s capacity, indicating how much charge it can hold. A higher Ah rating means a battery can provide power for a longer duration. For example, a 200Ah lithium battery can supply a certain amount of current for a longer time compared to a battery with a lower Ah rating.
Ohm expressed his discovery in the form of a simple equation, describing how voltage, current, and resistance interrelate: In this algebraic expression, voltage (E) is equal to current (I) multiplied by resistance (R). Using algebra techniques, we can manipulate this equation into two variations, solving for I and R, respectively:
The battery capacity can be calculated by multiplying the total battery current and the discharge time. For example, if a lithium-ion battery battery discharged at a voltage of 12V can provide a current of 100A for 1 hour, the battery capacity is 100A x 1 h = 100 Ah, which may also be called 12 volt 100ah lithium battery or 12v 100ah deep cycle battery, a …
