1. Storing Lithium Ion Batteries at The Right Temperature. The typical lithium ion battery storage temperature range of a home or storage unit is usually storing lithium batteries safely. The range of safe storage temperatures is wide, as shown in the chart below. However, issues like decreased battery lifespan occur in extreme weather conditions.
Improper storage of lithium-ion batteries in a warehouse or other location can lead to dangerous fires, even if there are protection measures built into the battery. The reason for this is the electrochemical construction of lithium-ion batteries, which consists of several components, each of which has certain chemical properties.
The most advantageous country of rate (SoC) for storing long-term lithium-ion batteries is around 30% to 50%. This range balances the need to minimize stress on the battery cells while stopping the battery from dropping to a damagingly low-rate stage throughout the garage.
Storage at 5°C to 15°C is optimal. Since lithium batteries self-discharge, it is recommended that they must be recharged every 12 months. We can further divide it into short-term storage and long-term storage.
So for the sake of your lithium battery pack and what you connect it to, we recommend separating the two when keeping them in extended storage, typically 3 – 6 months or longer. When you plan to store your battery pack for a long time, be sure to charge the battery to around 60 – 80 percent capacity.
There are no public UK regulations on the storage of lithium-ion batteries, however, it is still recommended that they be treated and stored as a hazardous material. According to UK regulations on hazardous material storage, lithium-ion and lithium-polymer batteries must be stored in appropriate hazardous materials cabinets and containers.
