    Conversion using the Battery Capacity Calculation Formula

    formula estimates the battery capacity in milliampere-hours (mAh) while accounting for efficiency losses (typically around 70%, or 0.7 efficiency factor):

    Battery Capacity (mAh) = Battery Life (hours) × Load Current (A)0.7

      Where:

    • Battery Life (hours): = Expected operating time before depletion.
    • Load Current (A): = The current drawn by the device.
    • 0.7 Factor: = Accounts for energy losses due to inefficiencies in battery discharge.
