Analysis on how to make the internal resistance self-discharge of the battery the lowest in Guizhou battery factory

   When we use the battery, sometimes after the battery is put into use, we cannot recharge the battery in time, causing the battery to lose power. When we use it next time, we will not be able to charge it normally. Therefore, our Venus Mong Kok technology suggests that the battery should be charged immediately after discharge.

   Batteries that have been out of service for a long time should be charged at least once a month. General salted batteries can be repaired by professional manufacturers, equipped with dry repair or rehydration repair. Severely damaged batteries should be handled by the manufacturer. The rated capacity of the battery should comply with the battery capacity specified in the national standard. The unit of Aher is the product of the discharge current and the full discharge time, and it represents the energy stored in the battery.

   The internal resistance of the battery is related to the discharge current. The instantaneous high-current discharge is caused by the rapid dilution of the sulfuric acid solution in the electrode plate gap and more than 90% of the sulfuric acid molecules outside the electrode plate hole have no time to diffuse into the electrode plate gap. The specific resistance of the solution in the plate hole increases, and the terminal voltage decreases significantly. But after the discharge is stopped, as the high-concentration sulfuric acid molecules diffuse into the gap between the electrode plates, the number of electrode plates of the same capacity battery is thinner than that of the thick electrode plate battery, making the internal resistance of the thin plate battery significantly smaller than that of the thick electrode plate. Hinder. Therefore, when the same current is discharged, the current density of the thin-plate battery is very small, and the polarization of each electrode is much smaller.

   The battery that the load discharges to the low power state must be charged within 72 hours after discharge to avoid damage to the battery. If the UPS is idle, disconnect the connected battery, otherwise the connected battery will be over-discharged and damaged within a few days to a week. If the battery is not charged for a long time after being discharged, it will cause the oxidation of the electrode plates. In other words, a large amount of crystallized or solidified lead sulfate remains on the metal plate of the battery, and the usual charging method will be difficult or impossible to decompose the lead sulfate again, resulting in premature damage to the battery.
