Why is the UPS battery capacity insufficient?

Analysis of the reasons for the insufficient battery capacity of the UPS power supply: When the battery is in use, sometimes we find that the use time of the UPS power battery is significantly shorter than before. This is because the battery capacity is already insufficient, and the reasons for the insufficient battery capacity are What about those? This chapter will discuss with you. 1. Long-term storage. After some customers have bought the battery, because there is no time to install the UPS power battery, the UPS power battery is always stored. The storage temperature and environment have a great impact on the battery. If stored in this way for a long time, it is easy to cause The battery capacity is insufficient; 2. The positive plate of the battery is corroded, and the capacity of the battery charge and discharge cycle is easily affected by the positive plate of the battery. The capacity drop under deep cycle is also closely related to the quality deviation of the positive plate, and the positive plate is easy to appear The common reasons that the problem affects the battery capacity are: 3. Sulfation of the negative plate due to various reasons is also a cause of insufficient battery capacity. The capacity of a battery is usually related to the following factors: ①The structure and number of the plates. When other conditions are the same, the capacity of the 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. ②Discharge situation. When the 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 voltage of the battery to drop rapidly and discharging cannot continue. Therefore, the discharge current increases and the battery capacity decreases. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
