As the use of lithium batteries becomes more widespread, learning how to properly operate, maintain, and store them is increasingly important. How to correctly use lithium batteries is a popular topic, but have you realized that how to store them is also worth paying attention to? After all, proper storage practices help maintain the performance of lithium batteries, extend their lifespan, and ultimately reduce your investment costs. So, let’s explore the value of this article together.

How To Store Lithium Batteries Safety?

This 12V 100Ah Delong lithium iron phosphate battery is very popular in some deep cycle applications. Although it is slightly more expensive than lead-acid batteries, to further improve cost-effectiveness, we need to store them more properly. Therefore, you might need to consider the following factors:

Operation Before Storage:

When you plan to give your lithium batteries a rest for a while, you need to disconnect them from the device and remove them. Whether your lithium batteries are used in RVs, golf carts, trolling motors, fish finders, or solar systems, removing them is an important step.

If you are storing the battery pack for a long period, you also need to charge the battery to 40% to 60% depending on the duration of storage. This is to prevent damage to the battery from being too low due to long-term self-discharge, as well as to avoid battery aging caused by storing at full charge.

Additionally, we recommend using labels to record information such as the storage date and state of charge of the battery. This facilitates your later inspection and maintenance, as well as documenting the results.

Storage Environment Requirements:

The choice of location for storing lithium batteries also requires some consideration. Generally, we need to pay attention to the following points

  • Temperature

Although lithium batteries can operate within a certain temperature range, one must not be complacent when storing them long-term! When batteries are kept under extreme temperature conditions, such as below 20°F or above 100°F, they are very likely to be damaged. They may experience accelerated self-discharge rates, increasing your maintenance costs. Therefore, it is highly beneficial to store them at an appropriate temperature range (20°F to 110°F).

  • Humidity

Just like storing rice, we generally keep batteries in a relatively dry place, ideally with humidity levels below 50%. A well-ventilated environment can prevent the batteries from becoming damp, which can lead to poor contact, poor performance, and other issues.

  • Avoid Direct Sunlight

Direct sunlight, or excessively strong sunlight, can cause the temperature of the battery and its surrounding environment to rise. An overheated environment is not beneficial for the battery and may even cause damage to both the exterior and interior of the battery. Therefore, try to find a cool place that can shield against sunlight.

  • Ventilation

In areas with good air circulation, heat dissipates more quickly, and a suitable temperature is more conducive to battery safety. If your lithium batteries are stored in enclosed spaces like a garage, installing vents or screens can help dissipate heat.
