In the process of using an uninterruptible power supply system, people tend to think that the battery is maintenance-free and not valued. However, there is data showing that the proportion of UPS mainframe failure or malfunction due to battery failure is about 1/3. It can be seen that strengthening the correct use and maintenance of the UPS battery has an increasingly important significance for extending the service life of the battery and reducing the failure rate of the UPS system. In addition to the selection of regular brand batteries, the following aspects should be used to properly use and maintain the battery: First, maintain a suitable ambient temperature. An important factor affecting battery life is the ambient temperature. The optimum ambient temperature required by battery manufacturers is between 20-25 °C. Although the increase in temperature increases 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 are generally maintenance-free sealed lead-acid batteries, and the design life is generally 5 years, which can be achieved under the environment required by the battery manufacturer. If the required environmental requirements are not met, the length of life will vary greatly. In addition, the increase in ambient temperature will result in an increase in the chemical activity inside the battery, which will generate a large amount of heat energy, which in turn will cause the ambient temperature to rise. This vicious cycle will accelerate the shortening of the battery life. Second, regular charge and discharge. The float voltage and discharge voltage in the UPS power supply have been debugged to the rated value at the factory, and the discharge current increases with the increase of the load. The load should be adjusted reasonably during use, such as controlling the electronic equipment such as the microcomputer. The number of units used. Under normal circumstances, the load should not exceed 60% of the rated load of the UPS. Within this range, the discharge current of the battery does not appear to be excessively discharged. UPS is connected to the mains power for a long time. In the environment where the power supply quality is high and there is little power outage, the battery will be in a floating state for a long time. Over time, the activity of mutual conversion of battery chemical energy and electric energy will be reduced, and the aging will be accelerated. 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 of the battery and the load. After a full-load discharge is completed, recharge for more than 8 hours as specified. Third, the use of communication functions. At present, most large and medium-sized UPSs have operability with computer communication and program control. Install the corresponding software on the microcomputer, connect the UPS through the serial/parallel port, run the program, and use the microcomputer to communicate with the UPS. Generally have the functions of information inquiry, parameter setting, timing setting, automatic shutdown and alarm. Through information inquiry, information such as mains input voltage, UPS output voltage, load utilization rate, battery capacity utilization, internal temperature and mains frequency can be obtained; through parameter setting, basic characteristics of the UPS, battery maintenance time, and The battery runs out of alarms, etc. Through these intelligent operations, the use management of the UPS power supply and its battery is greatly facilitated. Fourth, replace the waste / bad battery in time. At present, the number of batteries for large and medium-sized UPS power supplies ranges from 3 to 80, or even more. These individual batteries form a battery pack through circuit connections to meet the needs of the UPS DC power supply. In the continuous operation and use of the UPS, due to the difference in performance and quality, it is inevitable that the performance of individual batteries will decrease and the storage capacity will not meet the requirements. When one or more of the batteries in the battery pack are damaged, the maintenance personnel should perform an inspection test on each battery to eliminate the damaged battery. When replacing a new battery, you should strive to purchase the same type of battery from the same manufacturer. It is forbidden to mix acid-proof batteries and sealed batteries and batteries of different specifications.
