What are the factors related to the capacity of the battery? ①The structure and number of the plates. When other conditions are the same, the capacity of the UPS battery depends on the area of u200bu200bthe electrode plate and the porosity of the active material, so the electrode plate is usually made very thin. The thickness of the electrode plate of the battery is 1.45-3.0mm. ②Discharge situation. When the UPS battery is discharged to a large extent, due to the large amount of lead sulfate precipitation, the cross-sectional area of u200bu200bthe pores of the electrode plate is reduced, and it is difficult for sulfuric acid to penetrate the electrode plate from the surface. Therefore, when the discharge current increases, the sulfuric acid that penetrates into the pores of the electrode plate is not enough to compensate for the amount of sulfuric acid consumed per unit time, causing the battery's voltage to drop rapidly and discharging cannot continue. Therefore, the discharge current increases and the battery capacity decreases. ③The electrolyte temperature. When the temperature decreases, it is difficult for the electrolyte to penetrate into the electrode plate due to the increased viscosity. At the same time, when the temperature decreases, the resistance of the electrolyte increases and the voltage decreases, so the capacity of the UPS battery will decrease. ④ Density of electrolyte. Increasing the density of the electrolyte can increase the electromotive force of the battery and the ability of the electrolyte to penetrate the active material in the electrode plate, and reduce the resistance of the electrolyte, thereby increasing the capacity of the turtle pool. However, if you continue to increase the electrolyte density, the viscosity will increase. Therefore, when the electrolyte density exceeds a certain value, the electrolyte penetration rate will decrease, and the internal resistance will increase, and the plate vulcanization will increase, making the battery The capacity is reduced. So only when the electrolyte density is in the best state, the battery can obtain the maximum capacity. UPS battery voltage of 12v capacity has 2.2AH, 7AH, 14AH, 17AH, 24AH, 32AH, 45AH, 60AH, 80AH, 105AH, 120AH, 160AH, 198AH.
