How to properly use and maintain lithium ion UPS?


How to properly use and maintain lithium ion UPS and extend battery pack life? As the saying goes, correct use and maintenance of battery pack is one of the key factors to extend battery pack life and reduce the total failure rate of lithium battery UPS power supply. As a reliable power supply guarantee, UPS battery packs have been applied to various fields in computer rooms, data centers, and industrial equipment.

Lithium battery is an important part of the UPS system. Its pros and cons are directly related to the reliability of the entire UPS system. If the user can use and maintain it correctly, it can prolong its service life and affect the service life of lithium ion UPS. There are several points: installation, temperature, charging and discharging, load, charger selection and long-term charging, etc.

Regularly check the terminal voltage and internal resistance of each unit battery. The UPS power supply has been shut down for more than 10 days. Before restarting, the UPS power supply should be started without load.

The service life of a battery pack is closely related to the depth to which it is discharged. For users who have long-term UPS power supply at low voltage or frequent power outages, they should make full use of the peak power supply to charge the battery to ensure that the battery has sufficient charging time after each discharge.

When using the lithium ion UPS power supply, be careful not to adjust the operating point of the battery under-voltage protection too low. The available capacity of the battery is closely related to the ambient temperature. Under normal circumstances, the ambient temperature is generally required to be around 25°C.

Of course, in order to extend the service life of lithium battery packs, not only attention should be paid to maintenance and use, but also the load characteristics and size should be fully considered when selecting. The battery pack should be installed in a clean, cool, ventilated, and dry place as much as possible, and avoid the influence of sunlight, heaters or other radiant heat sources. The battery should be placed upright, not at an angle.
