How to maintain industrial UPS battery packs?

How to maintain the industrial UPS battery pack? Generally, UPS is widely used in a so-called sealed lead-acid battery without protection. Its price is relatively expensive, generally accounting for about 1/31/2 of the total processing cost of UPS, so UPS battery packs should be properly protected and maintained. , Is the key to extending the service life of UPS batteries. To this end, we should strive to achieve: (1) It is forbidden to over-current charging the UPS battery pack. Due to the simple overcurrent charging, the positive and negative plates inside the battery are bent, and the active material on the surface of the plate falls, resulting in a decrease in the available capacity of the battery, resulting in damage to the battery. (2) It is forbidden to charge the UPS battery pack over voltage. Due to overvoltage charging, the water contained in the electrolyte in the battery is electrolyzed into hydrogen and oxygen and escapes, thereby shortening the service life of the battery. (3) It is forbidden to over-discharge the UPS battery pack. Over-discharge simply sulfatizes the surface of the internal plates of the battery, which results in an increase in the internal resistance of the battery, and even reverse polarity phenomenon of individual batteries, resulting in permanent damage to the battery. (4) Regarding UPS that has not been used for a long time, in order to ensure that the battery has outstanding charging and discharging characteristics, it is best not to load the battery before starting from the beginning, and let the UPS use the charging circuit in the machine to float the battery for 1015 hours. Use; Regarding the UPS that has been operating for a long time in the backup condition, generally, let it operate in the inverter condition for at least 2 to 5 minutes every other month to intensify the battery of the UPS. (5) Replace waste/bad batteries in time. The number of batteries currently equipped with large and medium-sized UPS power supplies ranges from 3 to 96, or even more. These single storage batteries are connected by circuits to form a storage battery pack to meet the requirements of UPS DC power supply. When some of the batteries in the UPS battery pack are damaged, the maintenance personnel should inspect and test each battery to remove the damaged battery. (6) When using UPS batteries, pay attention to the various parameters of UPS. Various UPS power supplies should not work at full load. More than 20% power margin should be reserved. Good load control should be between 40% and 60% of UPS rated output power. . (7) The battery should be stored or installed in a dry and ventilated place, protected from direct sunlight, and kept away from heat sources and places prone to sparks.
