Estimate how long a battery will last based on its capacity and the current draw of a load. Enter battery capacity in Amp-hours or milliamp-hours and device consumption in mA to get the estimated battery life in hours.
Calculate the expected battery life time for any battery with this online tool or the formula. Enter the battery capacity, device consumption, discharge safety, awake and sleep time, and get the average consumption and battery life in hours or other units.
Estimate battery lifetime for microcontroller, IoT, and edge systems with different operating modes and power consumption rates. Choose from basic, intermediate, or advanced calculators and input battery capacity, current, and time parameters.
Battery Life Calculator. You just input the battery capacity that’s written on your battery (in Ah) and the calculated amp draw (load current), and the calculator will tell you how many hours the battery will last.
Calculate the runtime of a battery based on its capacity, consumption and discharge safety. Enter the values and get the battery life in hours and minutes using simple equations.
Calculate the battery life of your device based on capacity, consumption, efficiency, degradation, and temperature. Learn the formula, real-world scenarios, and expert tips to maximize battery life.
Estimate the number of hours a battery will last in clocks, microcontrollers, and gadgets powered by AA/AAA batteries. Input two out of three variables: battery capacity, device consumption, and estimated hours, and get the third one automatically.
