What are the influencing factors of UPS battery internal resistance?

What are the factors that affect the internal resistance of the UPS battery? ⒈Battery use time: With the increase of use time, the electrolyte loss, the corrosion of the electrode plate and the connecting strip, the sulfation of the electrode plate, the deformation of the electrode plate and the shedding of active materials, etc., cause the capacity of the battery to decrease. , The internal resistance of the battery becomes larger. ⒉The amount of charge of the battery: Due to the difference in the depth of electrolyte injected into the battery, the thickness of the reaction material on the electrode surface, the porosity of the electrode surface, etc., the internal resistance of the UPS power supply battery is different, and the amount of charge is also different. 3. Temperature: Changes in ambient temperature, such as rising, speed up the diffusion of reactive substances, charge transfer, electrode kinetic processes and material transfer are easier to proceed, so the internal resistance of the UPS battery is reduced. Otherwise, it will be added. 4. The battery model: different processing plants, different types, and different types of UPS power batteries, due to different electrode, electrolyte, diaphragm material formulations, different battery structures, and different assembly processes make the internal resistance of the battery different. 5. Measuring signal frequency: At present, many battery internal resistance measurements actually measure the impedance of the battery, which includes capacitive reactance, and the size of the capacitive reactance is related to the frequency of the measurement signal, making the measurement result of the battery internal resistance not objective.
