Battery Runtime Calculator
Estimate how long a battery can run a device based on battery capacity, voltage, power consumption, and system efficiency.
Runtime = Battery Energy (Wh) × Efficiency ÷ Device Power (W)
This calculator provides an estimate. Actual runtime can vary depending on battery age, temperature, discharge rate, device efficiency, battery condition, voltage conversion losses, and other operating conditions.
