Capacity Test Method 1, Appearance Inspection Test Method to check the appearance of the UPS battery, no leakage, deformation, crack, stain, corrosion, and nut loans, etc. 2. Capacity Test Method The battery main battery is mostly lead-acid-free maintenance storage battery, and the monomer battery voltage is 12V, in order to keep the battery pack substantially capacity, it is necessary to conduct a verification of the discharge test, which is: In the UPS power supply system, turn off the rectifier (UPS input), let the battery powers the load with the UPS directly, the battery pack is required to test the end pressure, temperature, specific gravity, room temperature and discharge time of each battery before and after the battery pack discharge.

30% to 40% of the rated capacity. After the discharge is over, the battery should be charged, and the charge should be 1.2 times that of the discharge power.

According to the measured data, the discharge curve is made, and it is time to test again. 3, the decision of the backward battery is low in the end voltage of the discharge, so the backward battery should be measured in the discharge state, if the end voltage is tested in the three-time discharge cycle, it can be sentenced to the backwardness in the group. Battery.
