The shallow UPS battery can be used for a few years
Many customers are wondering whether the life of the storage battery is a few years, why the design life is 10 years, the final use of about 6 years, small in here to say to you, the life of the shallow battery is generally between 5-8 years, but the battery life and maintenance of the use of direct correlation. The factors that affect battery life are as follows:

1, deep discharge

The molar volume of lead sulfate is larger than that of lead oxide, and the volume of active material expands at discharge. Mole lead oxide is transformed into Mohr sulphate, with a volume increase of 95%. The combination of two lead oxide molecules is not strong in itself. After the expansion of active material on the positive electrode during discharge, the two lead oxide particles gradually relaxed.

2. Overcharge

Charging a shallow battery will electrolyse water into oxygen and hydrogen. If excessive charging is serious, large amounts of oxygen will be deposited. Because of the strong oxidizing ability of oxygen, the precipitated oxygen also corrodes the plate, and the active material of the board will be separated, which will affect the service life of the battery.

3. The temperature is too high

When the battery temperature rises to less than 45 degrees C, it will be beneficial to the battery and prolong its service life. However, during the charging process, if the battery temperature is higher than 50 degrees, it will accelerate the corrosion of acid to the battery plate, and the battery shell will accelerate aging due to the increase of temperature.

4, sulfuric acid corrosion

The increase of sulfuric acid density in the electrolyte increases the capacity of the positive plate, thus increasing the capacity of the battery. However, the battery's self discharge will increase, the corrosion of the plate will accelerate, the two lead oxide will be loosely and off, the corrosion of the battery will increase, and the life of the battery will increase.
