Quick Answer
LiFePO4 batteries require storage in a cool, dry place, away from direct sunlight, to maintain their performance and longevity. They can be stored at temperatures between 0°C and 35°C (32°F to 95°F). Avoid storing them in extreme temperatures, moisture, or direct sunlight.
Storage Temperature Considerations
LiFePO4 batteries can be stored at temperatures between 0°C and 35°C (32°F to 95°F). Storing them at temperatures below 0°C (32°F) can cause a self-discharge rate of up to 2% per month, while temperatures above 35°C (95°F) can cause a self-discharge rate of up to 4% per month. It’s essential to keep them away from direct sunlight, as it can cause the battery to heat up and degrade faster.
Charging and Discharging Considerations
Before storing LiFePO4 batteries, make sure they are fully discharged to 2V per cell and then charged to 3.5V per cell to prevent damage. Avoid storing them in a fully charged state for extended periods, as it can cause the plates to degrade faster. When storing them for an extended period, it’s recommended to store them in a state of 50% depth of discharge (DOD).
Environmental Considerations
Store LiFePO4 batteries in a well-ventilated area, away from moisture and humidity. Avoid storing them in areas with high salt content, such as near the ocean, as it can cause corrosion and degradation. Keep them away from chemical substances, such as acids and bases, as they can cause a chemical reaction and damage the battery.
