Introduction

Even when not in use, LiFePO₄ batteries can lose capacity over time. Understanding the causes of degradation and applying effective prevention measures will significantly extend storage life.

1. Causes of Capacity Loss

• Over-discharge: Leaving batteries unused for months can cause voltage to drop below the safe threshold.
• High humidity: Moisture leads to corrosion and leakage.
• Excessive temperature: Heat accelerates electrolyte breakdown.

2. Prevention Measures

• Maintain SOC between 40%–60%.
• Keep in cool, dry environments with stable temperature.
• Use insulated containers or battery cabinets for large systems.
• Perform regular voltage checks every 90 days.

3. Importance of Monitoring Tools

Using a battery monitoring system allows you to track voltage, temperature, and humidity remotely. This is especially important for distributed energy storage installations.

Conclusion

With the right environment and maintenance schedule, capacity loss during LiFePO₄ battery storage can be minimized. Smart monitoring ensures longer lifespan and higher performance after reactivation.
