Battery Life Calculator
This calculator estimates the operating runtime of a battery-powered device by comparing total energy capacity against steady-state current draw.
Use this tool to:
- Estimate total runtime in both hours and days to determine the maintenance or recharge cycle for your project.
- Account for efficiency losses caused by self-discharge, voltage regulation overhead, and temperature fluctuations (typically 70%–90%).
- Visualize the discharge profile to see how remaining capacity diminishes over time under a constant load.
