1. What is the mAh Calculation?

The mAh (milliamp-hour) calculation converts energy capacity in watt-hours to charge capacity in milliamp-hours, which is useful for comparing batteries with different voltages.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Watt\text{-}Hours \) — Energy capacity of the battery (Wh)
• \( Volts \) — Voltage of the battery (V)
• 1000 — Conversion factor from amp-hours to milliamp-hours

Explanation: The formula converts energy capacity to charge capacity by accounting for the battery's voltage.

3. Importance of mAh Calculation

Details: Knowing the mAh rating helps compare batteries of different voltages and understand how long a battery will last at a given current draw.

4. Using the Calculator

Tips: Enter watt-hours (energy capacity) and volts (battery voltage). Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why convert watt-hours to mAh?
A: mAh is a more intuitive unit for comparing battery capacity when considering current draw over time.

Q2: What's the difference between Wh and mAh?
A: Wh measures energy capacity, while mAh measures charge capacity. Wh accounts for voltage while mAh doesn't.

Q3: Can I use this for solar batteries?
A: Yes, this works for any battery type including solar storage batteries.

Q4: How accurate is this calculation?
A: It's theoretically precise, but actual battery performance depends on temperature, age, and discharge rate.

Q5: What's a typical mAh for solar batteries?
A: Solar batteries often range from 100Ah (100,000mAh) to 400Ah (400,000mAh) at 12V or 24V.
