What are the reasons for the decrease in battery capacity of UPS power supply?

Reasons for the decrease in battery capacity of UPS power supply. In the maintenance work, we found that some base station UPS power supply batteries have a long service life. Some have even worked for more than ten years and can maintain the basic capacity; some are very different and only used The capacity has dropped severely in two to three years, and it can only last for about half an hour after a power outage. What is the reason? Please see below. 1. Long-term storage. After some customers buy UPS battery, because there is no time to install the battery, the battery is always stored. The storage temperature and environment have a great impact on the battery. If stored in this way for a long time, it is easy to cause UPS power battery capacity drops; 2. The positive plate of the UPS battery is corroded, and the capacity of the battery charge and discharge cycle is easily affected by the positive plate of the battery. The capacity drop under deep cycle is also closely related to the quality deviation of the positive plate. The common reasons that problems are prone to affect the capacity of the battery are: the accumulation of small holes in the positive plate after multiple discharge cycles increases, so that large holes are constantly added, which destroys the positive electrode structure and causes the active material to fall off. In addition, the positive grid is corroded and deformed by external factors, which seriously affect the capacity of the UPS power battery. 3. Sulfation of the negative plate due to various reasons is also a cause of insufficient capacity of the UPS battery. The reasons for the insufficient capacity of the battery are important. When we use the battery, we need to perform some simple maintenance on the battery, increase its usage rate, extend the life, and let the battery better serve the power system. 4. Temperature is an important factor affecting the decrease of UPS battery capacity. The higher the temperature, the greater the capacity of the battery. Therefore, the capacity of the battery and the specific gravity of the electrolyte change with the change of temperature. Of course, the temperature is limited, not unlimited. It can be seen that it is very necessary to keep the temperature within a certain range. The most ideal temperature is 25 degrees.
