Battery Runtime & Charge Calc

HTTPS

O aplikaciji

Estimate battery runtime, charging time and energy from the capacity, current and voltage you enter. Work backwards to find capacity for a target duration or current for a given runtime.

Pack mode combines cells in series and parallel to show voltage, capacity and energy in Wh. Save custom battery presets and revisit previous calculations in history.

Try different inputs to compare your assumptions. Results are estimates and depend on the actual load and operating conditions.

Adjust efficiency, reserve, battery voltage and load voltage for your scenario. Displayed, copied and saved results account for these inputs.

The app does not measure your phone’s battery health or assess whether a real battery assembly is safe.

Calculations account for efficiency, reserve, battery voltage and load voltage. Displayed, copied and saved results consistently reflect these inputs. French labels have been clarified.
