In recent years, the number of fires caused by lithium-ion batteries has increased. Every year, at least 25 people are seriously injured when using batteries at work. If you or your staff work with batteries, how can you protect your workforce and workplace from the dangers of fires.

Tip: Storing lithium-ion batteries safely is crucial to preventing accidents and maximize their lifespan of the batteries.

Here are some guidelines to follow for safe storage:

Charge Level                                                                                                                                                               

Ideally, store lithium-ion batteries at a charge level between 40% and 60%. This range helps minimize stress on the battery and prevents it from fully discharging or overcharging during storage.


Keep the batteries in a cool and dry environment. Extreme temperatures can damage the battery and reduce its performance. The recommended storage temperature range is usually between 20°C to 25°C (68°F to 77°F). Avoid storing them in areas with excessive heat or direct sunlight.

Avoid Moisture:

Ensure the storage area is dry and well-ventilated. Exposure to moisture can cause corrosion and damage the battery. Store batteries away from any liquids or sources of water.

Physical Protection:

Protect the batteries from physical damage, such as impacts, punctures, or crushing. This can lead to internal damage, leakage, or even a fire hazard.

Avoid Mixing:

Do not store loose batteries in close proximity, particularly if they are not individually protected. Contact between the terminals of multiple batteries can cause short circuits and lead to dangerous situations. If storing loose batteries, consider using individual plastic cases or sleeves for each battery.

Insulate Terminals:

If you’re storing loose lithium-ion batteries, ensure the battery terminals are insulated to prevent accidental short-circuiting. You can use electrical tape or protective caps specifically designed for battery terminals.

Separate from Combustible Materials:

Store lithium-ion batteries away from combustible materials, such as paper, fabric, or other easily ignitable substances. In the event of a battery failure, a fire can spread rapidly if in contact with combustible materials.

Avoid Prolonged Storage:

If possible, try to use the batteries regularly and avoid prolonged storage. Lithium-ion batteries have a limited shelf life, and extended periods of inactivity can lead to capacity loss or degradation.

Check Regularly:

Periodically inspect the batteries for any signs of damage, swelling, or leakage. If you notice any abnormalities, safely dispose of the battery according to local regulations.

Follow Manufacturer Guidelines:

Always refer to the manufacturer’s instructions and recommendations for storing lithium-ion batteries. Different battery chemistries or specific models may have additional requirements or precautions.

Tip: By following these guidelines, you can ensure the safe storage of lithium-ion batteries, minimize the risk of accidents, and extend their overall lifespan.
