What’s the best method to store and maintain LiFePO4 battery?

Apr 25, 2024

1) State of charge: 50%

2) Relative humidity: 45~85% H.R.

3) Temperature: * at -5~25℃ for 1 years and recharge to 3.3V (SOC 50%) to maintain the battery * at -5~35℃ for 3 months and recharge to 3.3V (SOC 50%) to maintain the battery * at -20~45℃ for 1 months and recharge to 3.3V (SOC 50%) to maintain the battery

4) A temperature of 60℃ or higher and extremely high relative humidity will accelerate the deterioration of battery performance.

5) A higher battery voltage it means higher SOC for long term storage will accelerate the deterioration of capacity.

6) A lower battery voltage it means lower SOC for long term storage will lead to over discharge, cells imbalance due to self-discharge and BMS consumption
