Storing lithium-ion batteries during extended periods requires careful attention to safety and longevity. Here are some best practices to ensure safe and efficient storage:
Best Practices for Storing Lithium-Ion Batteries
- Charge Level for Storage:
- Store lithium-ion batteries with a charge level between 40% and 60%. This helps minimize stress on the cells and prolongs battery life.
- Avoid storing batteries fully charged or completely depleted, as both conditions can affect cell health and longevity.
- Environmental Conditions:
- Temperature: Store batteries in a cool, dry environment with temperatures between 40°F (4°C) and 77°F (25°C) for optimal longevity. Avoid extreme temperatures, such as those near heaters or in direct sunlight.
- Humidity and Ventilation: Ensure good airflow to dissipate heat and humidity, reducing the risk of overheating.
- Physical Safety and Containment:
- Container Use: Store batteries in non-conductive containers or fireproof bags, such as a Lipo Sack, to protect against accidental fires.
- Prevent Short Circuits: Store batteries so they do not come into contact with each other or other conductive materials.
- Flammable Materials: Keep batteries away from flammable materials such as wood, carpet, or gasoline.
- Handling and Inspection:
- Handling with Care: Avoid mechanical abuse, such as dropping or crushing, which can lead to battery failure.
- Regular Inspections: Check batteries every three months during long-term storage to ensure they maintain the recommended charge level and to prevent degradation.
- Charging and Storage Location:
- Remove from Devices: Before storage, remove batteries from devices to prevent parasitic drainage.
- Charging Surfaces: Use non-combustible surfaces for charging to prevent fires in case of overheating.
- Dedicated Storage Area: Create a designated storage area for lithium-ion batteries, away from heat sources and flammable materials.
By following these guidelines, you can significantly reduce the risk of battery damage and fire hazards during extended storage periods.
