1. What is Battery Run Time Calculation?

Battery run time calculation estimates how long a battery will last under a specific load. It helps determine the duration a battery can power a device before needing recharging or replacement.

2. How Does the Calculator Work?

The calculator uses the battery run time formula:

Where:

• \( Voltage \) — Battery voltage in volts (V)
• \( Ah \) — Battery capacity in ampere-hours (Ah)
• \( Load \) — Power consumption of the device in watts (W)

Explanation: The formula calculates the theoretical run time by dividing the total energy capacity (voltage × Ah) by the power consumption rate (load).

3. Importance of Battery Run Time Calculation

Details: Accurate battery run time estimation is crucial for planning power requirements, selecting appropriate batteries for applications, and ensuring uninterrupted operation of electronic devices and systems.

4. Using the Calculator

Tips: Enter battery voltage in volts, battery capacity in ampere-hours, and load power in watts. All values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: Is this calculation accurate for all battery types?
A: This provides a theoretical estimate. Actual run time may vary based on battery chemistry, age, temperature, and discharge characteristics.

Q2: What factors affect actual battery run time?
A: Battery age, temperature, discharge rate, efficiency losses, and voltage drop under load can all affect actual performance.

Q3: How do I convert Wh to Ah?
A: Ah = Wh ÷ Voltage. This calculator uses Ah directly for convenience.

Q4: Does this work for series/parallel battery configurations?
A: For series: voltage adds, Ah stays same. For parallel: voltage stays same, Ah adds. Adjust inputs accordingly.

Q5: Should I include efficiency losses?
A: For more accurate results, consider multiplying the result by 0.8-0.9 to account for typical efficiency losses.
