UPS battery maintenance analysis

Maintaining a proper ambient temperature Generally speaking, the major factor that affects battery life is ambient temperature. Generally, the best ambient temperature required by battery processing manufacturers is between 20-25°C. Although the increase in temperature improves the discharge capacity of the battery, the price paid is that the life of the battery is greatly shortened. According to experiments, once the ambient temperature exceeds 25°C, the battery life will be shortened by half for every 10°C increase. Regularly charge and discharge the float voltage and discharge voltage in the UPS power supply have been adjusted to the rated value at the factory, and the size of the discharge current is increased with the increase of the load. The load should be adjusted reasonably during use, such as control The number of electronic devices used such as microcomputers. Under normal circumstances, the load should not exceed 60% of the UPS rated load. Within this range, the battery discharge current will not be over-discharged. Utilizing the communication function At present, most large and medium-sized UPSs have operability such as communication with microcomputers and program control. Install the corresponding software on the microcomputer, connect the UPS through the serial/parallel port, and run the program, you can use the microcomputer to communicate with the UPS. Generally, it has functions such as information query, parameter setting, on-time setting, automatic shutdown and alarm. Replace waste/bad batteries in time. The number of batteries currently equipped with large and medium-sized UPS power supplies ranges from 3 to 80, or even more. When one of the batteries in the battery pack is damaged, the maintenance personnel should inspect and detect each battery to eliminate the damaged battery. When replacing new batteries, you should try to buy batteries of the same manufacturer and the same model, and it is forbidden to mix acid-proof batteries, sealed batteries, and batteries of different specifications.
