Daily maintenance of lithium battery

Time:2021-01-19 Views:115

  Lithium primary battery has low self-discharge and can be stored for up to 3 years. The cold storage effect is better. It is a good way to store the power supply in a cool place. Lithium-ion batteries have a low self-discharge rate and can recover most of their capacity, so they can be stored for more than half a year at 20°C. Lithium-ion batteries have self-discharge. If the battery voltage is lower than 3.6V, long-term storage will cause the battery to over discharge, destroy the internal structure of the battery, and reduce the battery life.

  Therefore, the long-term storage power supply should be charged once every 3 to 6 months, that is, the charging voltage is 3.8~3.9V (Li-ion battery is best stored at about 3.85V), and it is not suitable to be fully charged. The application temperature range of lithium batteries is very wide. It can still be used outdoors in winter in the north, but the capacity will be reduced a lot. If it returns to room temperature, the capacity can be restored again, subject to a certain temperature. Unlike lithium batteries, dry batteries cannot be recharged, which is very dangerous. Other considerations are similar to cylindrical lithium batteries.
