- Before storing lithium batteries, ensure they are charged to around 50% of their capacity. Batteries stored at full charge or completely discharged may degrade faster over time.
- Choose Suitable Storage Conditions:
- Store lithium batteries in a cool, dry, and well-ventilated area away from direct sunlight and extreme temperatures. Ideal storage temperatures range between 15°C to 25°C (59°F to 77°F).
- Avoid storing batteries in places prone to high humidity, as moisture can lead to corrosion and damage.
- Use Proper Packaging and Containers:
- Store lithium batteries in their original packaging or in individual containers that provide protection against physical damage, short circuits, and environmental factors.
- Ensure that batteries are not stacked or stored in a way that may cause them to crush or puncture each other.
- Prevent Exposure to Extreme Temperatures:
- Avoid exposing lithium batteries to temperatures below freezing or above 60°C (140°F), as extreme temperatures can degrade battery performance and safety.
- If storing batteries in a vehicle, choose a location where temperatures remain within the recommended range, such as the passenger cabin rather than the trunk.
- Check Battery State Regularly:
- Periodically inspect stored batteries for signs of damage, leakage, or swelling. If you notice any abnormalities, remove the batteries from storage and dispose of them properly.
- Check battery voltage levels periodically and recharge as needed to maintain optimal storage charge levels.
- Store in Fireproof Locations:
- When storing large quantities of lithium batteries, consider storing them in fireproof cabinets or containers designed to contain fires in case of thermal runaway or accidents.
- Avoid storing batteries near flammable materials or in areas where fire hazards are present.
- Follow Manufacturer Recommendations:
- Adhere to manufacturer recommendations and guidelines for storing specific types of lithium batteries, as storage requirements may vary depending on battery chemistry, size, and application.
- Consult the battery datasheet or user manual for information on recommended storage conditions and shelf life.
- Keep Batteries Away from Children and Pets:
- Store lithium batteries out of reach of children and pets to prevent accidental ingestion or misuse.
- Educate family members and household members about the potential hazards associated with lithium batteries and the importance of proper storage and handling.
What will happen if lithium battery is not well storage?
Improper storage of lithium batteries can lead to various issues, including degradation of performance, reduced lifespan, and safety hazards. Here are some potential consequences of not storing lithium batteries properly:
- Accelerate the self-discharge rate:
- Lithium batteries have a natural tendency to self-discharge over time, even when not in use. However, improper storage conditions, such as exposure to high temperatures or humidity, can accelerate the self-discharge rate, causing batteries to lose their charge more rapidly.

- Capacity Loss:
- Exposure to extreme temperatures, especially high temperatures, can lead to capacity loss and reduced energy storage capabilities in lithium batteries. Over time, this can result in decreased runtime and overall performance when the batteries are eventually used.

- Swelling and Bulging:
- Lithium batteries may experience swelling or bulging when stored under conditions of high temperature or overcharge. This is typically caused by the buildup of gas inside the battery due to chemical reactions, leading to deformation of the battery casing and potential leakage of electrolyte.

Could you charge the lithium battery during long time storage?
During long-term storage, it’s generally recommended to periodically recharge lithium batteries to maintain their health and prevent capacity loss. The frequency of charging depends on several factors, including the type of lithium battery, storage conditions, and manufacturer recommendations.
- For lithium-ion batteries, it’s advisable to perform maintenance charging every 3 to 6 months during long-term storage. This involves partially charging the battery to around 50% to 70% of its capacity to prevent over-discharge and maintain optimal storage charge levels.
- Lithium iron phosphate (LiFePO4) batteries are more tolerant to long-term storage without maintenance charging. However, it’s still beneficial to perform occasional top-up charges every 6 to 12 months to ensure the battery remains in good condition.
- If batteries are exposed to high temperatures, high humidity, or other adverse conditions, more frequent maintenance charging may be necessary to prevent capacity loss and degradation.
- Lithium-ion batteries generally have higher self-discharge rates compared to lithium iron phosphate (LiFePO4) batteries, necessitating more frequent maintenance charging.
- Check if the battery pack includes BMS functionalities and follow any specific recommendations provided by the manufacturer for storage and maintenance charging.
- Regularly monitor the state of stored lithium batteries for signs of capacity loss, voltage drop, or physical damage. If batteries exhibit abnormal behavior or deterioration during storage, consider increasing the frequency of maintenance charging or consulting with the manufacturer for guidance.
How do we store the lithium battery in factory?
- Choose Suitable Storage Area:
- Select a dedicated storage area within the factory that is well-ventilated, cool, and dry. Avoid areas with direct sunlight, high temperatures, humidity, or moisture, as these conditions can degrade battery performance and safety.
