Storage time requirements for lithium batteries

Storage time requirements for lithium batteries

Lithium-ion batteries can be stored for 2 to 4 years when kept under optimal conditions. Their shelf life varies based on battery chemistry and usage. For best results, store them in a cool, dry place and charge to about 50% before storing. Avoid extreme temperatures to extend their lifespan.

6 FAQs about [Storage time requirements for lithium batteries]

What temperature should a lithium battery be stored?

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.

How do you store a lithium battery?

The best storage method, as determined by extensive experimentation, is to store them at a low temperature, not below 0°C, at 40% to 50% capacity. 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.

How should a lithium ion battery be charged before storage?

Before storage, lithium-ion batteries should be charged to the recommended state of charge (SoC) using a reliable battery management system or intelligent charger. Disconnecting the battery from the charger after reaching the desired SoC is essential to prevent overcharging.

How long should a lithium battery pack last?

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.

Where should lithium ion batteries be stored?

Lithium ion batteries should be stored in a suitable storage facility away from heat and ignition sources. The storage facility should offer temperature control, as batteries can be used at temperatures between -20°C to 60°C, but it's important to avoid reaching temperatures at the end of those ranges.

How often should a lithium battery be recharged?

The ideal storage range is between 5 and 10 degrees Celsius. It is advised that lithium batteries be rechargedonce every 12 months because they self-discharge. The two types of storage that we can distinguish are short-term and long-term.
