Battery Capacity Calculator

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 an ideal case, the battery capacity formula would be;

Battery Capacity = Battery Life in Hours x Battery Amp
