Introduction
Battery lifespan is a critical factor in solar energy storage systems. Since batteries are cycled daily, their longevity directly impacts system cost and performance.
Typical Lifespan
Lead acid batteries typically last:
- 3–10 years
- 500–2000 cycles
Factors Affecting Lifespan
Depth of Discharge
- Lower DOD = longer life
- Recommended: 50%
Temperature
- Ideal: 20–25°C
- High temperature shortens life
Charging
Improper charging can reduce lifespan.
Maintenance
Regular checks improve performance.
How to Extend Battery Life
- Avoid deep discharge
- Maintain proper charging
- Control temperature
Conclusion
With proper usage, lead acid batteries can provide reliable performance for many years in solar systems.
FAQ
