Introduction
While lead-acid batteries are reliable, they require proper maintenance and charging control to achieve their full design life.
1. Correct Charging Parameters
Ensure inverter and charge controller settings match battery specifications:
- Bulk voltage
- Absorption time
- Float voltage
2. Avoid Deep Discharge
Frequent deep discharge dramatically reduces cycle life. Energy management strategies should prioritize load optimization.
3. Periodic Inspection
Check for:
- Terminal corrosion
- Cable tightness
- Abnormal temperature rise
4. Equalization Charging (Flooded Batteries)
Regular equalization helps reduce sulfation and capacity loss.
Conclusion
Proper maintenance and charging strategies significantly improve system reliability and battery ROI.
