Formula and Equations for Battery Capacity Calculator. Battery Capacity in mAh = (Battery life in hours x Load Current in Amp) / 0.7. Battery Capacity = (Hours x Amp) / Run Time % Where;
Now that you have determined the total power requirement, you are ready to move on to the next step: selecting the battery capacity for your UPS system. Step 3: Selecting the Battery Capacity. Once you have calculated the total power requirement for your UPS battery backup, it is time to select the appropriate battery capacity.
For example, if a battery has a capacity of 5000mAh and the device has a power consumption of 100mA, the battery runtime can be calculated as follows: Battery Runtime = 5000mAh / 100mA = 50 hours It is important to ensure that the units are consistent when using this formula.
Total battery capacity needed, Ah – the calculated battery capacity you need what as a result of the above data entered. The total energy that could be stored in the solar battery /E/ in Wh or kWh could be calculated as follows: E[Wh]=Battery Voltage[V]x Total battery capacity needed[Ah].
