Battery Life Calculator

This calculator is used in electrical engineering to precisely calculate battery life. Generally, battery life is calculated based on the current rating in mAh(milli Amps per hour) and it is abbreviated as mAh. Ampere is an electrical unit used to measure the current flow towards the load. The battery life or capacity can be calculated from the input current rating of the battery and the load current of the circuit. Battery life will be high when the load current is less and vice versa. The calculation to find out the capacity of battery can be mathematically derived from the following formula:
