The battery minimizes the internal resistance self-discharge

　　 When we use the battery, sometimes we don’t charge it in time after the battery is discharged, which causes the battery to lose power. The next time we use it again, it can’t be charged and recharged normally. So our advice to everyone is that the battery is discharged It should be charged immediately.

　　 The battery should not be under-charged. Store the battery that has been out of service for a long time. First, fully charge the battery before storing, and recharge it at least once a month. General salted batteries can be dry repaired or rehydration repaired by professional merchants with a repair instrument. Severely damaged batteries should be dealt with by the manufacturer. The rated capacity of the battery should be in accordance with the battery capacity specified by the national standard. The unit is Ah. It is the product of the discharge current and the full discharge time and expresses the amount of power stored in the battery.

　　The internal resistance of the battery is related to the size of the discharge current. In the instant large current discharge, the sulfuric acid solution in the gap of the plate is rapidly diluted, and more than 90% outside the plate hole The sulfuric acid molecules in the solution are too late to diffuse into the gaps of the electrode plates, so that the specific resistance of the solution in the electrode plate holes increases and the terminal voltage drops significantly. But after stopping the discharge, as the high concentration of sulfuric acid molecules diffuse into the gaps of the plates, in addition, the internal resistance of the thin plate of the battery is significantly less than the thick plate, because the number of plates of the same capacity battery is thinner than that of the thick plate. The number of plates of a thick plate battery, so when the same current is discharged, the current density of a thin plate battery is small, and the polarization of each polarization is much smaller.

　　 A battery that is discharged to a low power state with a load. The battery must be recharged within 72 hours after discharge to avoid battery damage. The connected battery should be disconnected when the UPS is not in use. Otherwise, the connected battery will be over-discharged and damaged within a few days to a week. If the battery is not recharged for a long time after discharge, it will cause the plate to fail. Oxidation, that is, a large amount of crystals or solidified lead sulfate is left on the metal plate of the battery. The commonly used charging method will be difficult or impossible to re-decompose the lead sulfate, which will cause premature damage to the battery. Contact: 18038382979
