1. What is Battery Life Calculation?

The battery life calculation estimates how long a battery will last based on its capacity and the current draw of the connected load. This is essential for designing and planning power systems.

2. How Does the Calculator Work?

The calculator uses the basic battery life equation:

Where:

• Capacity — Battery capacity in amp-hours (Ah)
• Load Current — Current draw in amps (A)

Explanation: The equation simply divides the total available charge by the rate at which it's being consumed.

3. Importance of Battery Life Calculation

Details: Accurate battery life estimation is crucial for system design, ensuring adequate power supply duration for applications ranging from small electronics to large backup systems.

4. Using the Calculator

Tips: Enter battery capacity in Ah and load current in A. Both values must be positive numbers. The result shows estimated runtime in hours.

5. Frequently Asked Questions (FAQ)

Q1: Is this calculation accurate for all battery types?
A: This provides theoretical maximum. Real-world factors like temperature, discharge rate, and battery age affect actual performance.

Q2: What if my load current varies?
A: For variable loads, use average current or calculate for worst-case scenario.

Q3: How does battery voltage factor in?
A: This calculation works for single voltage systems. For multi-cell systems, calculate per voltage section.

Q4: What's a typical battery capacity?
A: Small batteries might be 0.1-10Ah, car batteries 30-100Ah, deep cycle batteries up to 500Ah.

Q5: How can I extend battery life?
A: Reduce load current, use higher capacity battery, or implement power-saving modes in your device.
