How do you calculate a battery Ah?

To calculate amp hours, you need to know the voltage of the battery and the amount of energy stored in the battery. Multiply the energy in watt-hours by voltage in volts, and you will obtain amp hours. Alternatively, if you have the capacity in mAh and you want to make a battery Ah calculation, simply use the equation: Ah = (capacity in mAh)/1000.

What is the relationship between voltage and current in a battery?

The voltage of a battery depends on the internal resistance of the battery and the current flowing through it. The relationship between these parameters is described by Ohm’s law. Battery voltage, V b (V) in volts equals the product of current, I b (A) in amperes and internal resistance, R b (Ω) in ohms. Battery voltage, V b (V) = I b (A) * R b (Ω)
