1. What is the Battery Life Calculator?

The Battery Life Calculator estimates how long a battery will last when powering a 1000-watt device, based on the battery's watt-hour (Wh) capacity.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Time \) — Battery life in hours
• \( Wh \) — Battery capacity in watt-hours
• \( 1000 \) — Device power consumption in watts

Explanation: This formula divides the total energy capacity of the battery by the power consumption rate of the device to determine runtime.

3. Importance of Battery Life Calculation

Details: Accurate battery life estimation is crucial for planning power requirements, selecting appropriate battery sizes, and ensuring uninterrupted operation of electrical devices.

4. Using the Calculator

Tips: Enter the battery capacity in watt-hours (Wh). The value must be greater than zero. The calculator assumes a constant 1000-watt load.

5. Frequently Asked Questions (FAQ)

Q1: What is a watt-hour (Wh)?
A: A watt-hour is a unit of energy equal to one watt of power expended for one hour of time.

Q2: Is this calculation accurate for all battery types?
A: This provides a theoretical maximum. Actual runtime may vary based on battery chemistry, age, temperature, and discharge rate.

Q3: How do I find my battery's Wh rating?
A: Many batteries list Wh directly. If not, you can calculate it by multiplying the voltage (V) by the amp-hour (Ah) rating.

Q4: What if my device uses less than 1000 watts?
A: The battery will last longer. Divide your battery's Wh rating by your actual device wattage to calculate runtime.

Q5: Does this account for power conversion losses?
A: No, this calculation assumes 100% efficiency. Real-world systems typically have 10-20% conversion losses.
