What are the maintenance methods for UPS power batteries?

Maintenance method of UPS power battery ◆Maintain a proper ambient temperature Generally speaking, the major factor that affects the battery life is the 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 the test, once the ambient temperature exceeds 25°C, the battery life will be shortened by half for every 10°C increase. At present, the batteries used in UPS power batteries are generally maintenance-free sealed lead-acid batteries, and the design life is generally 5 years, which can only be achieved under the environment required by battery processing manufacturers. If the specified environmental requirements are not met, the length of their lifespan will vary greatly. In addition, the increase of the ambient temperature will lead to the enhancement of the internal chemical activity of the battery, resulting in a large amount of heat energy, which in turn will promote the increase of the ambient temperature. This vicious circle will accelerate the shortening of the battery's life. ◆Regularly charge and discharge the float voltage and discharge voltage of the UPS power supply, which have been adjusted to the rated value at the factory, and 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. Because UPS is connected to the mains for a long time, in an environment with high power supply quality and few mains blackouts, the battery will be in a floating charge state for a long time, which will cause the battery's chemical energy and electric energy to convert between activity and accelerate aging And shorten the service life. Therefore, it should be completely discharged every 2-3 months, and the discharge time can be determined according to the capacity and load of the battery. After a full-load discharge is completed, charge it for more than 8 hours according to regulations. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
