What is the Battery Life Calculator?

The Battery Life Calculator helps users, engineers, and electronics enthusiasts estimate how long a battery can power a load based on its capacity and the current drawn by the device. By entering the battery capacity in ampere-hours and the load current, the tool calculates the expected battery life in hours. This is useful for planning usage, selecting the right battery, and ensuring uninterrupted operation of electrical devices.

How to Use:

1. Enter Battery Capacity (Ah): Input the battery’s rated capacity in ampere-hours.
2. Enter Load Current (A): Input the current drawn by the device connected to the battery.
3. Click “Calculate”: The calculator computes the estimated battery life using the formula: Battery Life = Capacity ÷ Load Current.
4. Review Result: The output displays the battery capacity, load current, and the estimated battery life in hours, highlighted for easy reference.
