Correctly use and maintain the battery: 1. Maintaining the right ambient temperature affects the important factor in battery life is ambient temperature, the best ambient temperature required by the general battery pack manufacturer is at 20 ¡ã C -25 ¡ã C. Although the temperature rise has improved on the battery discharge capacity, the cost of pay is greatly shortened by the battery life.
According to test assay, once the ambient temperature exceeds 25 ¡ã C, each liter is 10 ¡ã C, the life of the battery is shortened by half. 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 reach in the environment required by the battery packages. Without the prescribed environmental requirements, the length of life is very different.
In addition, an increase in the ambient temperature can cause the internal chemical activity of the battery, thereby appearing in a large amount of thermal energy, which has increased the surrounding ambient temperature, which speeds 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 and high supply quality, rarely occurring the city-electricity downtime, the battery will grow in a floating electricity, which will cause the battery chemical energy and electrical energy to reduce the activity, accelerate aging. Shorten service life.
Therefore, it is generally discharged once every 2-3 months, and the discharge time can be determined according to the capacity and load size of the battery. 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.
With information query, you can get the market-electrical input voltage, UPS output voltage, load utilization, battery capacity utilization, temperature and market-speed frequency, etc., can set UPS basic characteristics, battery sustain time and battery Well, etc. Through these intelligent operations, it greatly facilitates the management of UPS power 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, but 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, individual battery performance decreases, and the storage capacity does not meet the requirements and is inevitable.
When a certain / some battery cells in the battery pack, the maintenance personnel should check each battery to test the damaged battery. When replacing new batteries, you should strive to purchase a battery with the same model, prohibiting an anticone battery and a sealed battery, a battery mixture of different specificati.
