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 %
Battery Capacity = in mAH (milli Ampere hours)

Battery life = in Hours
Load Current = Consumption of device in Amperes
0.7 = Battery Cycle life considerations (Run Time)
Note: In ideal case, the battery capacity formula would be;
Battery Capacity = Battery Life in Hours x Battery Amp
