How to Safely Store Your Lithium-Ion Batteries

Lithium-ion batteries have now become a part of our everyday lives, from power tools and e-bikes to laptops and warehouse equipment; they have become essential to keeping things up and running.

According to new research by Aviva, more than half of UK businesses have experienced a lithium-ion battery incident, from overheating and smoke to full fires. These are happening in warehouses, offices, shops, and workshops across the entire country.

In this guide, we will help businesses understand best practices when it comes to the storage and charging of lithium-ion batteries and how to choose the right safes to protect your staff and property.

Why Proper Storage of Lithium-Ion Batteries Matters

Storing your lithium-ion batteries properly is extremely important for many reasons. Lithium-ion batteries are able to hold a lot of energy in just a small amount of space, which is great for charging things on the go, but it is also what can make them dangerous. Under certain circumstances, such as if the battery has been damaged by dropping or piercing the device, a chemical reaction inside the battery can cause it to short-circuit. This can cause the battery to severely overheat very quickly and go into ‘thermal runaway’, which can then lead to a fire or explosion.

If you keep your batteries too hot or too cold, leave them fully charged or completely drained for long periods of time, or even if you stack and store them incorrectly, this can then make the battery much more vulnerable to this type of damage. Doing this shortens the battery's lifespan and also leads to serious safety hazards.

Key Risk Factors of Lithium-Ion Batteries

Understanding the risks associated with lithium-ion batteries is the first step towards safer storage. Here are some of the key risk factors:

Temperature extremes

Storing your batteries in areas that are too hot or too cold can accelerate the degradation, which increases the chance of your battery failing. High temperatures are particularly dangerous, and these significantly increase the risk of a fire.

Physical damage

Dropping your battery, or crushing or puncturing it, can damage the internal cells, which can then lead to overheating or failure when you try to charge or use it. This type of damage isn't visible, so it’s important to be aware if this does happen.

Improper storage

Storing your lithium-ion batteries in unsafe areas, such as stacked in cardboard boxes or left to charge overnight, can seriously damage your battery and lead to serious safety hazards.

Exposure to water or humidity

Exposing your lithium-ion battery to moisture will damage the battery’s internal components, which can then lead to short-circuiting or corrosion, which can then cause failure and dangerous reactions.

Lithium-Ion Battery Storage Do’s and Don’ts

Following clear dos and don’ts will help you minimise risks and extend your battery’s life.

Do:

Make sure you store your lithium-ion batteries in a cool, dry and well-ventilated area
Aim for a storage temperature between 15 and 25°C
Store your batteries at a partial charge, ideally around 40 - 60 percent
Keep batteries away from any flammable materials
Make sure you inspect batteries regularly for swelling, leaks or damage
Use purpose-built charging safes designed specifically for lithium batteries

Don’t:

Store batteries in direct sunlight or near any heat sources
Leave batteries loose in drawers, boxes or on shelving
Stack batteries without separation or protection
Store damaged or swollen batteries with healthy stock
Charge batteries unattended or in unsuitable storage areas
Dispose of lithium-ion batteries in general waste

Simple habits like labelling storage areas and training staff on correct handling can also make a huge difference in reducing risk.

Essential Features to Look for in Lithium-Ion Battery Storage

Choosing the right lithium-ion battery safe is extremely important, especially in workplaces where multiple batteries are stored or charged at once. Here are some of the features you need to make sure to look for when you are choosing the right lithium-ion battery storage for your space:

Fire resistance

When looking for storage, make sure you are looking for units that are made from fire-resistant materials that are designed to contain any heat or flames if the battery does fail. This is especially important for higher-capacity batteries such as ones used in e-bikes, tools or industrial equipment.

Ventilation

Remember, good ventilation helps to prevent heat buildup and reduces the risk of overheating. Purpose-built cabinets are designed to allow controlled airflow without compromising safety.

Separation and organisation

Storage should prevent batteries from touching each other or metal surfaces. Internal compartments, dividers or individual slots reduce the risk of short circuits and accidental damage.

Security and access control

In workplaces, secure storage prevents unauthorised access and reduces the risk of mishandling. Lockable cabinets are particularly useful in shared environments.

Capacity and scalability

Consider how many batteries you need to store now and in the future. Overcrowding storage units increases risk, so choosing a solution that allows for growth is important.
