Long term storage of lithium batteries

release time:2024-05-07 Hits: Popular:AG11 battery

　　1. Lithium primary batteries

　　Also known as a lithium battery. It can be discharged continuously or intermittently. Once the electricity is depleted, it cannot be reused and is widely used in low power consuming electronic products such as cameras. Lithium primary batteries have low self discharge and can be stored for up to 3 years. Storing them under refrigerated conditions will result in better performance. Storing lithium primary batteries in a low-temperature place is a good method. Attention: Unlike lithium-ion batteries, lithium-ion batteries cannot be charged, making charging very dangerous!

　　2. Lithium ion batteries

　　Also known as secondary lithium batteries. It can be stored for more than half a year at 20 ℃ due to its low self discharge rate and most of its capacity can be restored.

　　The self discharge phenomenon of lithium batteries, if the battery voltage is kept below 3.6V for a long time, will cause the battery to over discharge and damage the internal structure of the battery, reducing the battery life. Therefore, lithium batteries that have been stored for a long time should be recharged every 3-6 months, that is, charged to a voltage of 3.8-3.9V (the optimal storage voltage for lithium batteries is about 3.85V), maintained at a discharge depth of 40% -60%, and should not be fully charged. Batteries should be stored in a dry environment between 4 ℃ and 35 ℃ or in moisture-proof packaging. Keep away from heat sources and avoid direct sunlight.

　　The application temperature range of lithium batteries is very wide. They can still be used outdoors in winter in the north, but their capacity will decrease significantly. If they return to room temperature, their capacity can be restored.
