What is Battery life Calculator?

An electric battery is one or more electrochemical cells that convert stored chemical energy into electrical energy. There are two types of batteries. Primary batteries or disposable batteries, which are designed to be used and disposed of once, and secondary batteries or rechargeable batteries, which are designed to be recharged and used multiple times. Battery life depends on the rated capacity of the battery and the device used. Battery capacity is expressed in terms of ampere hours.

It is used to calculate battery life by applying the latest online battery life calculator formula.


Calculate battery life for the details provided.
Enter battery capacity rating: 25 mAh
Enter device consumption: 15 mm amps

Apply Formula:
BLT= Capacity of battery / Consumption of the device * 0.70 BLT = 25/15*0.70

BLT = 1.1666 Hours
