What are the reasons for the bulging and deformation of UPS batteries?

Causes of UPS battery swelling deformation The swelling deformation of the battery is mainly caused by the surge of internal pressure. The important reasons are as follows: ● During the charging operation of the sealed battery, especially in the series battery pack, if the battery pack has been carried out Charging, if there is a battery of poor quality, there will often be phenomena such as poor internal gas recombination, resulting in bulging. ●The opening pressure of the safety valve is too high, or the safety valve is blocked. When the internal pressure increases to a certain level, the valve cannot be opened normally. In this case, it is bound to cause bulging deformation. ●Because the sealed battery is a lean-liquid design, there is a reserved way for the gas combination, and if there is a rich liquid phenomenon, it will block the O2 from diffusing to the negative electrode, reduce the recombination rate of O2, and increase the internal pressure. ●Float charging voltage is set too high and the charging current is large, resulting in faster O2 precipitation on the positive electrode plate, and it is too late to recombine on the negative electrode. At the same time, the temperature in the battery rises quickly. The sealed lead-acid battery is bulging and deformed. Due to many factors, the use of UPS batteries often fails to reach its design life. Take the battery used by UPS power supply in the current market, usually after 3-5 years of use, the battery will need to be replaced, and some customers have to replace it in two years if it is improperly maintained.
