What Does mAh Mean?

mAh is a unit that measures (electrical) power over a period of time. It is widely used to measure a battery’s energy capacity.

What does watt-hour mean?

The watt-hour, represented by the symbol Wh, is a unit of energy equal to one watt of power used for one hour.

Q = 1000 x E / V

The above formula indicates that the amount of electric charge, expressed in milliamps, can be determined by first multiplying the energy, expressed in watt hours, by 1000, and then dividing the resulting number by the voltage, expressed in volts.

The energy should be entered in watt-hours (Wh), and the voltage should be entered in volts (V) below:
