1. What is Run Time Calculation?

Run time calculation determines how long a battery will last when powering a device. It's calculated by dividing the battery's capacity (in watt-hours) by the power consumption of the device (in watts).

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• Capacity — Battery capacity in watt-hours (Wh)
• Power — Device power consumption in watts (W)

Explanation: This formula gives the estimated time a battery can power a device before needing recharge or replacement.

3. Importance of Run Time Calculation

Details: Calculating run time is essential for selecting appropriate batteries for devices, planning power requirements, and ensuring uninterrupted operation of electronic equipment.

4. Using the Calculator

Tips: Enter battery capacity in watt-hours and device power consumption in watts. Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between Wh and mAh?
A: Watt-hours (Wh) measure energy capacity, while milliamp-hours (mAh) measure charge capacity. Wh provides a more accurate measure of battery life as it accounts for voltage.

Q2: How accurate is this calculation?
A: This provides an estimate. Actual run time may vary based on battery age, temperature, discharge rate, and other factors.

Q3: Can I use this for different battery types?
A: Yes, the formula works for all battery types (Li-ion, NiMH, lead-acid, etc.) as long as you use watt-hours for capacity.

Q4: What if my device has variable power consumption?
A: Use the average power consumption for estimation, or calculate run time for different usage scenarios.

Q5: How do I convert mAh to Wh?
A: Multiply mAh by voltage (V) and divide by 1000: Wh = (mAh × V) / 1000
