Battery Life Calculator

Battery Life Calculator is used to calculate the expected life of a battery under specific conditions of use. 

What is the battery life?

Battery life is the amount of time a battery can power a device before needing to be replaced. The battery life is determined by the battery capacity, the power consumption of the device, and the usage time of the device.

battery life

The formula for calculating the battery life is:

Battery life = Capacity of battery/Consumption of the device x 0.70

How to calculate battery life?

Try our Battery life calculator above to calculate the life of a battery in no time. Here is an example to calculate the battery life manually.


Calculate the life of a battery if the battery capacity is 5000 and the consumption of the device is 500.


Step 1: Write the given information.

Battery capacity = 5000

Consumption of the device = 500

Step 2: Take the formula for calculating battery life.

Battery life = Capacity of battery/Consumption of the device x 0.70

Step 3: Substitute the values in the formula and simplify them in the correct order of operations.

Battery life = 5000 / 500 x 0.70

Battery life = 10 x 0.70

Battery life = 7
