Lithium have become a popular choice for various electronic devices due to their high density and long-lasting performance. Whether you have spare batteries or need to store them while traveling or during a power outage, it’s important to properly store them to maintain their safety and effectiveness. In this article, we will discuss some key tips on how to store lithium batteries.
1. Check the Charge Level: Before storing lithium batteries, make sure to check their charge level. It is generally recommended to store lithium batteries at about a 40-60% charge. If the battery is fully charged or discharged, it may lead to performance degradation or even damage. If needed, use a charger or discharger to adjust the battery’s charge level.
2. Remove from Devices: If you plan to store lithium batteries for an extended period, it is advisable to remove them from the electronic devices they power. Leaving batteries inside devices can lead to drainages, causing them to discharge over time. By removing them, you ensure they remain at a stable charge level.
3. Choose the Right Environment: Selecting a suitable environment for storing lithium batteries is crucial. It is important to keep them in a cool, dry place away from direct sunlight and extreme temperatures. Exposure to heat or cold can negatively affect their performance and lifespan. Optimal temperatures for storage range between 15-25°C (59-77°F).
4. Avoid Humidity: Moisture is a significant threat to lithium batteries. It can corrode contacts and cause damage. Therefore, it is crucial to store batteries in a dry environment. Consider storing them in airtight or sealed containers, such as a plastic bag or a battery case, to prevent any form of moisture exposure.
5. Protect from Physical Damage: Ensure that lithium batteries are protected from physical damage during storage. Avoid storing them with sharp or metallic objects that could potentially puncture or short-circuit the battery. Store them in a secure location where they won’t be accidentally dropped, crushed, or mishandled.
6. Be Mindful of Battery Types: Different lithium battery chemistries may require specific storage considerations. For example, lithium-ion batteries, commonly found in smartphones or laptops, should be stored at a lower charge level. On the other hand, lithium polymer batteries, often used in drones or small electronic devices, should be stored at a slightly higher charge level. Consult the manufacturer’s guidelines for specific storage instructions based on battery types.
7. Regularly Check on Batteries: While storing lithium batteries, it’s a good practice to periodically check on them. Inspect for any signs of damage, corrosion, or leakage. If any issues are identified, exercise caution and follow proper disposal methods as per local regulations.
8. Prevent Overcharging: Even during storage, lithium batteries should not be left connected to a charger for an extended period. Overcharging can result in overheating, reduced performance, or even safety hazards. Once the desired charge level is reached, disconnect the charger promptly.
By following these tips, you can ensure the safe and optimal storage of lithium batteries. Remember to always refer to the manufacturer’s guidelines for specific instructions, and dispose of damaged or expired batteries responsibly. Proper storage will help maintain the quality and longevity of your lithium batteries, ensuring they are ready for use whenever you need them.
