1. What is the 100Ah Lithium Battery Life Calculator?

This calculator estimates the runtime of a 100Ah lithium battery based on the discharge current. It helps determine how long the battery will last under specific load conditions.

2. How Does the Calculator Work?

The calculator uses the simple battery life equation:

Where:

• \( Battery\ Capacity \) — 100Ah (for this calculator)
• \( Discharge\ Rate \) — Current drawn from battery in Amperes (A)
• \( Life \) — Runtime in hours (h)

Explanation: The equation calculates theoretical runtime by dividing battery capacity by discharge current.

3. Importance of Battery Life Calculation

Details: Accurate battery life estimation is crucial for system design, power management, and ensuring uninterrupted operation of devices powered by lithium batteries.

4. Using the Calculator

Tips: Enter discharge current in Amperes (A). The value must be greater than 0. For best results, use typical average current draw.

5. Frequently Asked Questions (FAQ)

Q1: Is this calculation accurate for real-world usage?
A: This provides theoretical maximum. Real-world runtime may be 10-20% less due to efficiency losses, temperature, and battery aging.

Q2: Can I use this for lead-acid batteries?
A: While the calculation is similar, lead-acid batteries have different discharge characteristics and should not be discharged below 50% for best lifespan.

Q3: What's the maximum safe discharge rate?
A: Most lithium batteries can safely discharge at 1C (100A for 100Ah), but check manufacturer specifications for your specific battery.

Q4: How does temperature affect battery life?
A: Cold temperatures reduce available capacity, while high temperatures can accelerate battery degradation.

Q5: Should I include inverter efficiency?
A: If using an inverter, multiply the result by inverter efficiency (typically 0.85-0.95) for more accurate AC runtime estimates.
