How to store lithium batteries?

Date of Issue:2020-07-15 Click:

The self-discharge of lithium primary battery is very low and can be stored for 3 years. It will be better if stored under refrigerated conditions. It is a good way to store lithium primary batteries in a cold place.

Lithium-ion batteries can be stored for more than half a year at 20°C because of their low self-discharge rate and most of the capacity can be recovered.

The self-discharge phenomenon of lithium batteries, if the battery voltage is kept below 3.6V for a long time, it will cause the battery to over discharge and destroy the internal structure of the battery, reducing the battery life. Therefore, long-term storage of lithium batteries should be recharged every 3 to 6 months, that is, charged to a voltage of 3.8 to 3.9V (the best storage voltage of lithium batteries is about 3.85V), and it is not suitable to be fully charged.

Lithium batteries have a wide application temperature range. They can still be used outdoors in winter in the north, but the capacity will be much lower. If they return to room temperature, the capacity can be restored.
