First, maintaining a suitable ambient temperature usually, affecting the factors that affect the life of the UPS power battery life is ambient temperature. General ambient temperature required by general battery packages is between 20-25 ° C. Although the temperature rise has improved on battery discharge capacity, the cost of pay is a big shortened battery life.

According to experimental assay, once the ambient temperature exceeds 25 ° C, 10 ° C per liter, the life of the battery is shortened. Second, the floating voltage and discharge voltage in the regular charging discharge UPS power supply, all debugged to the rated value during the factory, and the size of the discharge current increases with the increase of the load, and should be reasonably adjusted reasonably. For example, the number of applications such as electronic devices such as microcomputer.

Under normal circumstances, the load should not exceed 60% of the UPS rated load. Within this range, the discharge current of the battery will not excessive discharge. Third, the communication function is currently, the vast majority, medium-sized UPS has operational performance such as microcomputer communication and program control.

Install the appropriate software on the microcomputer, connect the UPS through the string / parallel port, run the program, you can use the microcomputer to communicate with the UPS. Generally have information queries, parameter settings, setup, automatic shutdown and alarms, etc. Through the information query, you can get information on the mains input voltage, UPS output voltage, load utilization, battery capacity utilization, temperature and market frequency; through parameter setting, the basic characteristics of UPS can be set, the battery can last time and Battery for agency, etc.

Through these intelligent operations, it greatly facilitates the management of UPS power supplies and its battery. Third, timely replacement of waste / bad batteries Currently, the number of batteries equipped with large and medium-sized UPS power supplies, from 3 to 96 不, even more. These single batteries constitute a battery pack through a circuit connection to meet the UPS DC power.

In the continued operational use of UPS, due to performance and quality, individual battery performance has decreased, and the storage capacity is not required to be damaged. When a certain / some batteries in the battery pack is damaged, the maintenance personnel should check the detection of each UPS power battery to exclude damaged batteries. When replacing new batteries, you should strive to purchase a battery with a model of the same model, prohibiting an antagonized battery and a sealed battery, different specifications of batteries.
