Battery Run Time Calculator

This is the Battery Run Time Calculator. By providing the battery capacity and device consumption, the calculator will estimate how long the battery will last, and the time can be converted between hours, days, weeks, months, and years. However it's for estimates only because the battery condition, lifespan, temperature, discharge rate, and other factors may cause the difference. The estimated results from a run time between 1 hour and 1 year are the most representative of actual results when using the new and high-quality batteries at room temperature.
