1. What is Lithium Battery Lifespan?

The Lithium Battery Lifespan calculation estimates the total operational hours of a lithium-ion battery based on its charge cycles and runtime per cycle. This helps in predicting battery longevity and replacement schedules.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• Lithium Life Cycles — Total number of charge/discharge cycles the battery can perform
• Run Time per Cycle — Average hours the battery lasts per full cycle

Explanation: The total lifespan in hours is simply the product of how many cycles the battery can handle multiplied by how long each cycle lasts.

3. Importance of Lifespan Calculation

Details: Calculating battery lifespan helps in maintenance planning, cost estimation, and ensuring uninterrupted power supply for critical applications.

4. Using the Calculator

Tips: Enter the manufacturer-specified cycle life and your typical runtime per cycle. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical cycle life for lithium batteries?
A: Most lithium-ion batteries last 300-500 cycles before capacity drops to 80% of original, though high-quality ones may reach 1000+ cycles.

Q2: Does partial charging affect cycle count?
A: Partial discharges (e.g., 50% discharge) count as half cycles. The calculator assumes full cycle equivalents.

Q3: What factors reduce actual lifespan?
A: High temperatures, deep discharges, fast charging, and storage at full charge can all reduce practical lifespan.

Q4: How accurate is this calculation?
A: It provides theoretical maximum. Real-world conditions typically result in 10-30% shorter lifespan.

Q5: Can this be used for other battery types?
A: The calculation works similarly for other chemistries, but cycle life values differ significantly.
