Why UPS battery repair is invalid

(1) The quality and manufacturing quality of lead-acid batteries. (2) The charging mode of the charging equipment matched with the lead-acid battery does not match the battery. If the lead-acid battery is not matched with the charging equipment when charging, the charging voltage is too high, and the charging time is too long, which will cause the analysis of the water in the electrolyte to accelerate, and the hydrogen and oxygen that appear can not be completely recombined inside the battery, thus accelerating the battery loss , And increase the corrosion of the electrode plate, accelerate the aging of the battery and the occurrence of early failure. (3) When the UPS battery is charged with an excessive current, the battery will burst if the charging current is too high, and the battery life will be greatly shortened. (4) Dirt is deposited on the upper and lower parts of the electrode plates, causing short circuits. (5) The users of lead-acid batteries cannot use and maintain the batteries in accordance with the battery maintenance requirements. If the lead-acid battery is overused, the power will be overdrawn, and the conductive bridge between the lead dioxide particles on the positive plate will be degraded, and part of the contact between the lead dioxide particles and the contact between the lead dioxide particles and the grid will be lost, which means As the isolated particles no longer participate in the electrochemical reaction, the mechanical strength of the active material is weakened, and the possibility of falling off increases. Excessive use will also make the expansion agent in the negative electrode active material useless due to oxidation, and will increase the formation of irreversible sulfate crystals. Frequent overuse will cause the active material to lose its activity prematurely, and the conversion capacity of the active material will be weakened during charging, which will lead to accelerated capacity decay and early failure of lead-acid batteries. (6) Throwing, falling, and collision may cause damage to the battery's plastic shell. In severe cases, it may cause damage to the lugs and the inside of the pole plate, which will cause the battery to completely fail and be discarded prematurely.
