Introduction to the factors affecting the life of UPS battery

Factors that affect the life of UPS power batteries; temperature has a greater impact on UPS power batteries, too high or too low will cause the battery life to decline, especially high temperature, the impact on battery life is particularly clear. Generally speaking, the ambient temperature should be controlled at about 25°C. The depth of discharge depth of discharge has a great impact on the service life of the UPS battery. The greater the depth of battery discharge, the less the number of cycles it uses, so beware of deep discharge as much as possible when using it. Discharge of small current is easy to cause deep discharge. Floating charge voltage Because the UPS power battery is a standby mode of operation, the mains is in a charging state under normal conditions, and it will only be discharged when the power is cut. In order to prolong the service life of the battery, the float voltage should be set reasonably. Too low floating charge voltage will lead to insufficient charging and irreversible sulfation of the negative electrode of the battery; too high floating charge voltage will accelerate water loss and corrosion of the positive plate. In addition, batteries of different models, specifications, and batches cannot be mixed. Mixed use will result in inconsistencies in the float voltage of each single cell. Charging current The charging and discharging current of UPS power supply battery is generally expressed by C, and the actual value of C is related to the battery capacity. For example, a 100AH u200bu200bbattery, Cu003d100A. Generally speaking, the best charging current for lead-acid maintenance-free batteries is about 0.1C. Excessive or too small charging current will affect the service life of the battery. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
