Since their introduction in 1991, lithium-ion batteries remain popular with companies large and small due to their long life and lightweight design. Today, we use them as primary power sources for smartphones, laptops, tablets, energy storage systems, and even electric vehicles.

However, if lithium batteries are not stored properly, they can be very dangerous. In this article, we'll give some advice on how to store lithium batteries.

Temperature is critical to understanding how to store lithium batteries. The recommended storage temperature for most people is 59℉ (15℃), but this is not the case. 

Therefore, before storing lithium batteries, carefully read the proper storage label for the specific battery type. Lithium-ion battery storage buildings with climate control are ideal for storing large quantities of lithium-ion batteries at specific temperatures to ensure a safe storage environment.

Also, pay attention to the state of charge at the time of storage. Nickel and Li-Ion batteries should be stored at around 40% state of charge. Lithium-ion batteries can become unstable if stored improperly. Be sure to know the details specific to your battery. Ignoring such information could result in overheating, which could damage the inside of the battery and possibly cause a fire.

Some batteries are specified to be charged between 30% and 50%. The battery can be stored fully discharged, but the battery voltage should not drop below 2.0 for optimal safety. The maximum voltage should not exceed 4.1 volts. Always follow the charging instructions that come with each lithium-ion battery.

Monitor battery charge status while charging

Make sure the temperature control is set to the specified temperature

Observe runtime with a fully charged battery

Ensure battery self-discharge

Check the battery for abnormal state of charge before storing

Avoid exposing Li-ion batteries to excessive vibration

Do not expose the battery to high or low temperatures

Always handle batteries with care

Store batteries after the building have reached compliant temperature levels

Do not use damaged batteries

Do not rub your eyes if in contact with liquid. Rinse eyes immediately at the eyewash station

Wash hands after handling batteries
