1. What is Battery 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:

• \( \text{Energy} \) — Energy in watt-hours (Wh)
• \( \text{Voltage} \) — Voltage in volts (V)

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

3. Importance of Battery Capacity Calculation

Details: Calculating battery capacity is essential for determining how long a battery can power a device, sizing batteries for specific applications, and comparing different battery types and technologies.

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 capacity, while ampere-hours (Ah) measure charge capacity. Wh takes voltage into account, making it a more universal measure of energy storage.

Q2: Why is battery capacity important?
A: Battery capacity determines how long a device can run on a single charge and helps in selecting the right battery size for specific power requirements.

Q3: Can I use this formula for all battery types?
A: Yes, this formula works for lithium-ion, lead-acid, nickel-metal hydride, and other battery types as long as you know the energy content and operating voltage.

Q4: How accurate is this calculation?
A: The calculation provides theoretical capacity. Actual capacity may vary due to factors like temperature, discharge rate, and battery age.

Q5: What is a typical battery capacity range?
A: Battery capacities vary widely - from small button cells (10-100 mAh) to large automotive batteries (50-100 Ah) to industrial batteries (1000+ Ah).
