Wh: Watt-hour
V: Battery voltage
mAh: milliampere-hour
Calculation formula: Wh/V*1000= mAh
For example: battery capacity is 37Wh and battery voltage is 7.7V. Converted to mAh: 37Wh/7.7V*1000≈4805mAh
The milliampere-hour (mAh) is the main unit. of ampere-hour (Ah) Small unit. 1Ah = 1000mAh Generally, the power of cell phone batteries and rechargeable batteries is mAh. It is defined as the current generated by a complete discharge under a certain discharge time. that the battery discharges in 1 hour. The internal full discharge current is 1300 mA hour is the unit of electricity 1 mA hour is equal to 3.6 coulombs.
