Introduction
One of the most compelling advantages of LiFePO₄ batteries is their exceptionally long cycle life. Compared to traditional lead-acid and other lithium batteries, LiFePO₄ technology delivers far greater longevity and value over time.
What Defines Cycle Life?
Cycle life refers to the number of complete charge–discharge cycles a battery can perform before its capacity drops to a defined threshold (usually 80%).
LiFePO₄ Cycle Life Performance
High-quality LiFePO₄ batteries typically offer:
- 4,000–6,000 cycles at 80% DoD
- Over 8,000 cycles at moderate depth of discharge
This translates into 10–15 years of service life in most stationary energy storage applications.
Comparison with Other Battery Types
| Battery Type | Typical Cycle Life |
|---|---|
| Flooded Lead-Acid | 500–800 cycles |
| AGM/Gel Lead-Acid | 800–1,500 cycles |
| NMC Lithium | 2,000–3,000 cycles |
| LiFePO₄ | 4,000–6,000+ cycles |
Reduced Capacity Degradation
LiFePO₄ batteries experience slower aging and maintain stable capacity even after thousands of cycles, ensuring consistent system performance.
