In the process of using the UPS power system, people often think that the battery is maintenance-free without paying attention. However, there is a data display that the UPS host failure or the proportion of the working abnormal work is approximately 1/3 due to battery failure. It can be seen that the correct use and maintenance of the UPS battery is enhanced, and the service life of the battery is extended, and the UPS system failure rate is reduced, and there is an increasingly important significance.

In addition to selecting well-known brand batteries, it should be used to properly use and maintain the battery from the following aspects: 1 Maintaining a suitable ambient temperature affects the important factor in battery life is ambient temperature. The best ambient temperature required by the general battery manufacturer is 20 Between ¡ã C -25 ¡ã C. Although the temperature rise has improved on battery discharge capacity, the cost of pay is a big shortened battery life.

According to test assay, once the ambient temperature exceeds 25 ¡ã C, 10 ¡ã C per liter, the battery life should be shortened. At present, the battery used by the UPS is generally maintenance-free sealed lead-acid battery, and the design life is generally 5 years, which can reach in the environment required by battery manufacturers. Without the prescribed environmental requirements, the length of life is very different.

In addition, the ambient temperature is improved, causing the internal chemical activity of the battery, there is a lot of thermal energy, which will increase the temperature rise in the ambient temperature, which will speed up the life of the battery. 2 Regular charging discharge The floating voltage and discharge voltage in the UPS power supply are debugged to the rated value during the factory, and the size of the discharge current increases with the increase of the load, and the load should be reasonably adjusted. Number of applicants for controlling 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. UPS is connected to the market due to long-term power supply, and the battery will have a long-term power supply in a long time, and the battery will result in a long time to reduce the activity of battery chemistry and electrical energy to reduce the activity, accelerated aging.

Shorten service life. Therefore, it is generally discharged every 2-3 months, and the discharge time can be determined according to the capacity of the battery and the load size. After the full load is complete, it will charge more than 8 hours according to the regulations.

3 Using communication functions, most large, medium-sized UPS has operational performance with micro-machine 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. 4 Timely replacement of damaged batteries Current large-scale UPS power supply equipped with a large number of batteries.

These batteries constitute a battery pack through a circuit connection to meet the power of UPS power. In the continuous operation of UPS, due to performance and quality differences, individual battery performance is lowered, and the storage capacity does not meet the requirements and is inevitable. When a certain / some batteries in the battery pack, the maintenance personnel should check each 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 anti-acid battery and a sealed battery, a battery of different specificati.
