The computer and communication industries have developed rapidly in recent years, and VRLA batteries have long been the first choice for UPS energy storage，They are proven in long-term applications and have a lower upfront purchase cost than other batteries, so they are widely used in large quantities，However, due to improper battery management and maintenance, safety problems caused by batteries frequently occur。
1. Before installing the UPS battery, pay attention to check the battery casing to confirm whether it is damaged, and further confirm whether it will affect the quality of the battery product，Considering that the battery will generate heat during charging and discharging, there should be an appropriate installation distance between the batteries in the battery pack to facilitate the battery to dissipate heat。
2. Batteries generally can be put into use after 3 months of production，Before installing batteries, confirm the time interval between battery production, installation and use，Whether the battery needs to be charged according to the factory time of the battery, and check the terminal voltage and capacity test of the battery one by one，Batteries of different brands and capacities cannot be combined in the same set of batteries，The battery pack cannot be a combination of old and new，Avoid affecting the efficiency and service life of the battery due to inconsistent working conditions of the old and new batteries。
3. The pole of UPS battery forms an oxide film in the air, so the battery needs to clean the surface of the pole with a copper wire brush to remove the oxide layer on the surface of the pole and reduce the contact resistance。The length of the connection line between the battery and the positive and negative poles of the charging device should be as consistent as possible to ensure a high current discharge and maintain a working balance between the battery packs，After the battery is installed, the quality, capacity and internal resistance of the installed battery should be detected, recorded and archived to lay the foundation for the operation, maintenance and management of the battery。
There are hundreds of devices in the computer room. It is very necessary to monitor the operation of these devices. Through a perfect monitoring system, many failures can be greatly avoided。The battery monitoring system performs online monitoring of important parameters such as battery cell voltage, internal resistance, temperature, and current of the battery pack，Once a parameter is found to be abnormal or its changed parameters are abnormal, an alarm will be issued immediately, which can prompt the maintainer to find problems or potential hidden dangers in time to ensure the reliability and safety of the UPS system
