If the use of lithium battery UPS power supply is not correct, it will seriously reduce the capacity of lithium battery, serious time will make the UPS lithium battery scrap, shorten the life of the UPS battery, so it must be reasonable protection and use of lithium battery. today.

1, maintain a suitable temperature
For general UPS lithium batteries, you should try to ensure that the temperature of the environment is between 20 and 25 degrees Celsius. In addition, if the external ambient temperature is too high, it will also increase the internal chemical reaction speed of the lithium battery, which in turn will promote the speed of the ambient temperature rise, and this vicious cycle will rapidly accelerate the depreciation of the lithium battery UPS to a large extent, thus affecting the normal use.

2, the lithium battery for regular charge and discharge

In the daily maintenance of UPS lithium batteries, the battery power should be emptied, and then charged at normal 0.2C~0.5C to 50%SOC, and then properly stored. Proper regular maintenance can avoid overdischarge damage to lithium-ion batteries.

3, master the basic knowledge of lithium battery UPS

Before use, carefully read the instructions of the equipment, and make clear the meaning of various warning information, warning code, and indicator light, as well as the causes and countermeasures. Familiar with the function of various switches and buttons on the equipment. Familiar with UPS lithium battery operations, clear connection relationship.

4, timely replacement of waste/bad UPS lithium battery

In the continuous operation and use of lithium battery UPS, due to the difference in performance and quality, it is inevitable that the performance of individual batteries will decline and the storage capacity will not meet the requirements. Periodically check the UPS battery terminal voltage and internal resistance of each unit. When one or more batteries in the lithium battery pack are damaged, the maintenance personnel should inspect and test each battery to eliminate the damaged battery.
