How to extend the service life of UPS lithium battery pack?

1. Regularly check the terminal voltage and internal resistance of each unit UPS lithium battery pack. For 12V battery cells, if the terminal voltage difference between each battery cell exceeds 0.4V or the internal resistance of the battery exceeds 80m during the inspection, the battery cells should be charged in a balanced manner to restore the internal resistance of the battery. And eliminate the terminal voltage imbalance between each unit cell. 2. Re-float, UPS power supply battery has been shut down for more than 10 days, before restarting, UPS power supply should be started without load to use the charging circuit in the machine to re-float the lithium battery pack for more than 10~12h and then bring it Load operation. 3. Pay attention to the choice of charger. The maintenance-free sealed battery for the UPS lithium battery pack cannot be charged with a SCR-type quick charger. This is because this kind of charger will cause the battery to be in a bad state of charge of both instantaneous overcurrent charging and instantaneous overvoltage charging. 4. Ensure the ambient temperature of the UPS power supply. The available capacity of lithium batteries is closely related to the ambient temperature. In general, the performance parameters of the battery are calibrated at a room temperature of 20℃. When the temperature is lower than 20℃, the available capacity of the lithium battery will be reduced, and when the temperature is higher than 20℃, it can be used The capacity of will be slightly increased.
