Battery Life Calculator

How to use the calculator?

  • For this calculator, enter the battery capacity in mAh.
  • Know the device consumption and enter the value in mA.
  • Enter the consumption rate. If you do not know the consumption rate, enter the value as ‘0.7’.
  • The calculator would show automatically the calculated value.

How to calculate Battery Life?

You can calculate the battery runtime with help of the following formula:

Formula to Calculate Battery Life

Battery runtime = (Battery capacity in mAh / Load current consumption in mA) X Consumption rate

Example: Let us say you have a 10000 mAh battery. The load is drawing 500 mA current. The battery life would be 14 hours considering the consumption rate as 0.7.
