The performance of UPS batteries is very superior. In normal times, you should maintain a suitable ambient temperature, charge and discharge them regularly, and replace spent/bad batteries in time. The following mainly shares the characteristics of UPS batteries.

Due to the differences in the types of plates, manufacturing conditions and use methods, the reasons for the failure of batteries are different. To sum up, the failure of lead-acid batteries has the following situations: 1. Corrosion variant of positive plate There are three types of alloys currently used in production: traditional lead-antimony alloys, with an antimony content of 4% to 7% by mass; low antimony or ultra-low antimony alloys, with an antimony content of 2% by mass or less than 1% by mass Fraction, containing tin, copper, cadmium, sulfur and other modified crystal agents; lead-calcium series, actually lead-calcium-tin-aluminum quaternary alloy, the content of calcium is 0.06% to 0.1% mass fraction. The positive grids cast from the above alloys will be oxidized into lead sulfate and lead dioxide during the charging process of the battery, which will eventually lead to the loss of the function of supporting active substances and the battery failure; or due to the formation of lead dioxide corrosion layer, lead to lead dioxide. The alloy produces stress, which causes the grid to grow and deform. When the deformation exceeds 4%, the entire plate will be destroyed, and the active material will fall off due to poor contact with the grid, or short-circuit at the bus bar.
