Every battery operated product is designed to use one of the battery sizes everyone is so familiar with. How to Calculate Battery Life. The capacity of the battery can be numerically gotten from the following equation.
The RSL10 Power Consumption and Battery Estimator is an easy-to-use accurate tool that allows you to calculate and verify the exact power measurements for your IoT device and specific use-cases.
C-rate is used to describe how fast a battery charges and discharges. Battery capacity is typically measured in Amp-hours Ah or milliamp-hours mAh although Watt-hours Wh is. For example a 1C battery needs one hour at 100 A to load 100 Ah. Calculating battery life begins with the battery.
