Charging method is incorrect to the UPS power battery harm. In the process of using the UPS uninterruptible power supply system, people often think that the battery is maintenance-free without paying attention. When the user bought the UPS power supply, I used it to buy it, I can charge it without electricity.

I don't have reasonable use of the UPS power battery life to decrease, and push the responsibility to the manufacturer. The following Xiaobian introduces the charging method to incorrect the harm of the UPS power storage battery, I hope to help everyone. The charging method is incorrect to the UPS power storage, the ultra-discharge of the UPS battery is excessive discharge, which can cause the battery to use, can not be used again, can not charge, etc.

, severely cause the battery to scrap. Battery charger is a very important part of the UPS power supply, and the charging conditions of the UPS power battery have a great impact on battery life. If the battery is always in a constant voltage or "floating" electrical charge, the UPS power battery life can maximize.

In fact, the life of the battery charge is much longer than the life of a simple storage state. Because battery charging can delay battery natural aging processes, UPS should keep battery charging regardless of operation or downtime. UPS power battery correct charging method 1, strictly forbidden to charge UPS power battery overcurrent.

Since the overcurrent charge is easily caused by the positive, negative plate bending, the active material of the plate surface is detached, resulting in a decrease in battery capacity, resulting in damage to the battery. 2, strictly forbidden to charge the battery pack of the UPS power supply. Because overvoltage charging can cause water contained in the electrolyte in the battery to exceed hydrogen and oxygen, thereby shortening the battery life of the battery.

3. Excessive discharge of UPS battery pack is strictly prohibited. Because over-discharge is easy to cause sulfate of the internal plate surface of the battery, the result is that the internal resistance of the battery is increased, and even the individual battery appears "inverse polar", resulting in permanent damage to the battery.

4. About the UPS power supply for long-term idle, in order to ensure that the battery has good charge and discharge characteristics, it is best not to add the load before reopening, so that the charging circuit in the UPS power battery can be charged 10 ~ 15 Use after hours. UPS power storage battery is properly used and maintenance 1 Maintain a suitable ambient temperature.

Important factors affecting battery life is ambient temperature, and the best ambient temperature required by general battery manufacturers is between 20-25 ¡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 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 Regular charging discharge. The floating voltage and discharge voltage in the UPS uninterruptible 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 reasonably, such as controlling the microcomputer. The number of applicants such as electronic equipment.

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 use communication function. Currently, 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 replace waste / bad batteries in time. At present, the number of batteries equipped with large and medium UPS uninterruptible 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 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.

The above is the top ten reasons for the damage of the UPS power storage battery, have you all understand? The quality of the battery is directly related to whether our equipment can be used normally. Therefore, the UPS power storage battery pack will be properly extended, and the UPS battery life will be largely extended and reduce the fault rate. So, the maintenance of the UPS power storage battery is the ke.
