Introduction

Humidity may seem harmless, but it can significantly affect the performance and safety of stored LiFePO₄ batteries. Understanding this factor is essential for users in coastal or tropical regions.

1. Risks of High Humidity

When humidity exceeds 70% RH, metallic connectors and BMS terminals may corrode. Over time, this leads to voltage imbalance and micro-current leakage.

2. Recommended Storage Conditions

Keep humidity below 60% RH and temperature between 15°C–25°C. Use dehumidifiers, silica gel packs, or vacuum-sealed packaging to minimize moisture exposure.

3. Inspection and Maintenance

Regularly inspect terminals and casing for signs of oxidation or condensation. If detected, clean immediately using a dry cloth and repackage the battery in a sealed container.

Conclusion

Controlling humidity is a vital part of LiFePO₄ battery storage. With proper dehumidification and maintenance, batteries can retain stable voltage and excellent performance for years.
