　　Domestic lithium 18650 battery maintenance status

　　The maintenance of UPS batteries is similar to the maintenance of batteries in general low-voltage systems. When a new battery is introduced, it requires project acceptance and deep discharge; when a new lithium 18650 battery is put into use, it is required to maintain a suitable battery working environment temperature and regularly measure each battery terminal. When the voltage difference between each battery is too large, equal charging must be carried out. It is required to conduct exploratory capacity tests or deep discharges on the batteries regularly in order to check the performance of the battery pack and maintain the activity of the battery.

　　1. Power on and off sequence

　　In order to prevent the UPS from being damaged by the inrush current generated by the load at the moment of startup, the UPS should be powered on in bypass mode first, and then turn on the loads one by one, thus avoiding the impact of the load current on the UPS. The service life of the UPS is extended. The shutdown sequence can be seen as the reverse process of the startup sequence. First, turn off the loads one by one, and then turn off the UPS.

　　2. Before starting up

　　Before turning on the machine, you first need to confirm whether the polarity of the input mains connection is correct to ensure personal safety. Note that the total load power cannot be greater than the rated power of the UPS. The UPS should be prevented from working in an overloaded state to ensure that the UPS can work normally.

　　3. After shutting down

　　After the mains power is interrupted and the lithium 18650 battery pack supplies power and automatically shuts down, do not use the lithium 18650 battery pack to power on again to avoid battery damage due to excessive discharge. When the mains power supply is abnormal and the lithium 18650 battery pack supplies power, the load should be turned off immediately and the machine should be turned off again after the mains power supply returns to normal.

　　4. Pay attention to safety

　　Since the voltage of the lithium 18650 battery pack is very high, there is a certain risk of electric shock to the human body. Therefore, safety guarantees should be ensured when loading and unloading conductive connecting strips and output lines. The tools used should be insulated, especially the output contacts should be equipped with settings to prevent electric shock.

　　5. Charging voltage

　　During the charging process of the UPS, if the charging voltage is too high, it will cause the battery pack to be overcharged, and vice versa, it will cause the battery pack to be undercharged. When the charging voltage is abnormal, battery configuration data may be incorrect. Therefore, when installing the battery pack, you must pay attention to the correctness of battery specifications and quantity. Batteries of different specifications and brands should be avoided as much as possible. It is also best not to use low-priced and low-quality external chargers.
