When the charging voltage is abnormal, it may cause errors in the configuration data of the lithium battery. If the charging voltage is too high, it will lead to overcharging of the battery pack. If the charging voltage is too low, it will cause insufficient charging of the lithium battery pack. So when charging, pay attention to whether the voltage matches, and do not use low-priced and low-quality external chargers.

　　Attention should also be paid to the current during charging, and excessive current should be avoided during charging, as long-term high current charging can cause deformation of the battery plate, increase its internal resistance, and in severe cases, lead to a serious decrease in its capacity, greatly reducing its service life.

　　Lithium ion battery UPS should avoid deep discharge during use, as the deeper the battery discharge, the fewer times it will be cycled.

　　Usage environment

　　Lithium battery UPS power supply does not have high requirements for environmental temperature as it stores energy using lithium batteries, and can operate within -20-60 ℃.

　　In addition to certain temperature requirements, lithium battery UPS also has requirements for the cleanliness of the operating environment. The usage environment of UPS requires less dust and dryness. Long term exposure to dusty and humid environments can cause malfunctions in the internal components of the UPS.
