In addition to selecting a regular brand battery, the battery should be used correctly 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 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 test assay, once the ambient temperature exceeds 25 ° C, 10 ° 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 increases, causing the internal chemical activity of the battery, there is a lot of thermal energy, which will continue to increase the surrounding ambient temperature, which will speed up the life of the battery. 2 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. 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 have 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.

4, timely replacement of waste / bad batteries currently have the number of batteries equipped with large and medium-sized UPS power supplies, from 3 to 80 不, even more. These single batteries constitute a battery pack through a circuit connection to meet the UPS DC power supply. 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 specifications. Summary Through the discussion of how to use and maintain the battery in the UPS power supply, four solutions are introduced, including: maintaining a suitable ambient temperature, regular charging discharge, using communication function and timely replacement waste / bad batteries.

From the analysis process, you can understand the little bit of life in life, only you carefully discover the characteristics of various components, you will learn more.
