Ampere Hour (AH) for Battery

An ampere hour (abbreviated Ah, or sometimes amp hour) is the amount of energy charge in a battery that will allow one ampere of current to flow for one hour.

An ampere is a unit of measure of the rate of electron flow or current in an electrical conductor.

How to calculate the AH of a battery?

The formula to calculate AH is:

Amp Hours (AH) = Watt Hours/Volts

For Example:

The battery capacity of a 12 Watt Solar Street Light is 9.6 V and 57.6 Watt Hours.

Amp Hours(AH) = 57.6/9.6 = 6 AH
