If it is 4.2V, it can be said that the relationship between the discharge time of 26Wh and the current is 26wh/4.2V = 26vah/4, 2v = 6, 19Ah = 6 190 mAh at 4.2v, that is to say, it takes 6/kloc-to discharge at a current of100ma.
Wh is the electric quantity, which is directly proportional to voltage, current and time. MAh is usually used as an indicator of battery charging and discharging, which is directly proportional to the charging (discharging) current and time of the battery. To make it comparable or convertible with Wh, it is necessary to know the battery voltage.
According to the definition of current: I=Q/t, we can know that Q=It, the unit of current I is mA (milliampere), and T stands for time, and the unit is hours, so the unit of battery capacity is mAh. If the capacity of a battery represents 1000mAh and the current at work is 1000 ma, it can theoretically supply power for10 hour.
Conversion relationship between degrees and kilowatt hours
Calculation formula: electricity consumption (kW) = power (kW) × service time (hours), and watt is unit of power. If you multiply power by another time, the result is work. The unit of work is Joule and kWh, and the conversion relationship is as follows.
1 joule = 1 watt-second, 1 kwh = 1 kwh = 10003600 watt-second = 36000000 joules, that is, 1J = 65438. Therefore, the relationship between degree and kilowatt-hour and joule is: 1 degree = 1 kilowatt-hour = 36000000 J, that is, 1 kilowatt-hour equals 3,600,000 joules.
