Battery Life Calculator

This battery life calculator estimates the battery life based on the nominal capacity and average current consumed by the load.

Unit Explanation

  • Battery capacity is usually measured in ampere hours (Ah) or milliampere hours (mAh)
  • 1 ampere hour (Ah) = 1000 milliampere hours (mAh)
  • Watt-hour (Wh) conversion formula: Ah = Wh / V (V is the nominal voltage of the battery)
Calculation Formula
Battery Life =
Battery Capacity (mAh) Load Current (mA)
0 weeks 0 days 0 hours 0 minutes
Estimated Battery Life:
0.00 weeks
* Results based on ideal conditions

Important Notes

Calculation Result Explanation

The above result is a theoretical estimate based on ideal conditions. Actual usage time may be affected by the following factors:

  • Battery condition and usage years
  • Environment temperature
  • Discharge rate
  • Other external factors

Best Usage Conditions

Under these conditions, the calculation result is closest to the actual value:

  • Using a new high-quality battery
  • Working in a room temperature environment
  • Working time between 1 hour and 1 year
