Safe storage of rechargeable lithium-ion batteries

Fire protected and certified

Laptops, e-scooters, e-bikes, pedelecs, golf carts, cordless hammers, powerful garden tools – rechargeable lithium-ion batteries have become indispensable in the modern world. Unlike conventional batteries, lithium-ion cells can store energy in a smaller space. These indispensable power sources are found in most electronic instruments and are used today in almost every area of ​​life.

Although lithium-ion batteries seem harmless, they are not without dangers. In particular, lithium-ion batteries have some risk of fire and explosion. Due to their high energy density, they can ignite spontaneously under certain conditions or become unstable and explode when heated. If a technical defect occurs or the battery fails, this can have serious consequences for people and the environment.

Are you using electrical appliances or other products with lithium-ion batteries that need to be stored safely and charged in an optimal environment? China Lithium-Ion golf cart battery factory has the solution!

When properly handled and stored, the use of lithium-ion batteries is considered safe. However, there are isolated cases where batteries during operation spontaneously ignite and start fires.

Lithium-ion batteries are made up of dozens of layers of coated metal sheets. The positive and negative charged layers are only separated from each other by a very thin protective layer (separator). If any of these protective layers cracks, the stored energy can be released uncontrollably and cause a fire. Possible reasons are:

·        Electrical overload (during charge and discharge)

·        Overheating (thermal overload caused by external heat or power sources) or by

·        Shock (mechanical damage releasing the high energy density of the battery)

When one of these situations occurs, serious consequences can result. The battery catches fire and may even explode. That releases toxic gases that can be lethal. Lithium-ion battery fires are difficult to control and spread quickly. Firefighters are often limited to preventing the fire from spreading to neighboring areas.

China custom EV lithium-ion battery , therefore, requires that lithium batteries be “treated primarily as a dangerous substance.” You will find general information on the storage of lithium batteries at

What to pay attention to avoid damage?

► Compliance with the manufacturer’s specifications

 ► Short-circuit protection of the battery poles

 ► Protection against mechanical damage

 ► Do not expose immediately and permanently to high temperatures or heat sources

 ► Maintain a structural or space separation (at least 2.5 m ) concerning other combustible materials, if there is no automatic extinguishing system

 ► Immediate removal of damaged or defective batteries from storage and production areas (intermediate storage until disposal, at a safe distance or in a separate area without risk of fire extension)

 ► Store only batteries with approval certificate according to UN 38.3 (prototypes only in exceptional cases and after a risk assessment)

 ► Store in separate fire-resistant areas or with an adequate safety distance (5 m spatial separation)

 ► Avoid joint storage with other combustible products

 ► Control of the storage area using a suitable fire alarm system connected to an always attended workplace

 ► If there are fire extinguishing systems: Take into account the information on the extinguishing media appropriate in the technical data sheets of the products, LifePo4 Golf Cart Battery Pack Supplier.


If a battery catches fire, the consequences can be devastating. To prevent this situation and avoid damage, rechargeable lithium-ion batteries must be stored and charged in special fireproof safety cabinets. Fire-resistant safety cabinets are currently considered one of the safest ways to store rechargeable lithium-ion batteries.
