Battery Life Calculator Overview:

The Battery Life Calculator is a handy tool for estimating the runtime of a battery. It allows you to calculate how long a battery is expected to last based on its capacity and the amount of current consumed by the circuit. The formula for this calculation is:
Battery Life= Capacity/Consumption

Capacity: This refers to the storage capacity of the battery and is typically measured in milliampere-hours (mAh). You can usually find this information printed on the battery.
Consumption: This is the average current draw of your electronic device and is measured in amperes (A) or milliamperes (mA).

Let’s consider an example to illustrate how the battery life is calculated:.

Capacity (mAh): 2000 mAh
Consumption (mA): 50 mA

Using the formula:
Battery Life=2000mAh/50mA

Battery Life=40hours

In this example, with a battery capacity of 2000 mAh and a consumption of 50 mA, the estimated battery life is 40 hours. This means the battery is expected to last for approximately 40 hours under the given conditions.
