1. What is Battery Power Capacity?

Battery capacity is a measure of the charge stored by the battery, typically measured in ampere-hours (Ah). It represents the amount of electric charge a battery can deliver at the rated voltage.

2. How Does the Calculator Work?

The calculator uses the battery capacity formula:

Where:

• \( Energy \) — Energy in watt-hours (Wh)
• \( Voltage \) — Voltage in volts (V)
• \( Capacity \) — Result in ampere-hours (Ah)

Explanation: This formula converts energy stored in watt-hours to capacity in ampere-hours by dividing by the battery voltage.

3. Importance of Battery Capacity Calculation

Details: Calculating battery capacity is essential for determining how long a battery will last under specific loads, designing power systems, and selecting appropriate batteries for various applications.

4. Using the Calculator

Tips: Enter energy in watt-hours (Wh) and voltage in volts (V). Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between Wh and Ah?
A: Watt-hours (Wh) measure energy, while ampere-hours (Ah) measure charge. They are related through voltage: Wh = Ah × V.

Q2: Why is voltage important in capacity calculation?
A: Voltage determines how much energy each unit of charge carries. The same charge (Ah) at higher voltage delivers more energy (Wh).

Q3: Can I use this for all battery types?
A: Yes, this formula works for any battery type (Li-ion, lead-acid, NiMH, etc.) as it's based on fundamental electrical principles.

Q4: How accurate is this calculation?
A: The calculation is mathematically precise, but actual battery performance may vary due to temperature, discharge rate, and age factors.

Q5: What is a typical battery capacity range?
A: Capacity varies widely: small batteries might be 0.1-5Ah, car batteries 30-100Ah, while large industrial batteries can be 1000+ Ah.
