To estimate battery run time, multiply the battery’s ampere-hour rating by 10, then divide by the device’s wattage.
The Battery Run Time Calculator is a handy tool for gauging how long a battery will last when powering a specific device. Knowing battery runtime helps you plan power usage, whether for gadgets, vehicles, or backup systems.
By inputting the battery’s ampere-hour rating and the device’s power consumption in watts, this calculator gives a quick estimate of battery life, helping substantially in power management and planning.
Formula
T = (10 ∗ a) / w
| Variable | Description |
|---|---|
| T | Run Time (hours) |
| a | Battery capacity (ampere-hours) |
| w | Device power consumption (watts) |
