By releasing 30-40% of the rated capacity, we can grasp the approximate capacity of shengyang battery to ensure the reliable operation of the power supply system.The method is:
1. In the dc power supply system, adjust the output voltage of the rectifier to its protection voltage, and the actual communication load will be supplied by shengyang battery.The end voltage, temperature, room temperature and discharge time of each battery should be measured and recorded before and after discharge of the SACREDSUN battery.Until 30- 40% of the rated capacity is released.
2. After the discharge, the sunyang battery should be charged.
3. Draw the discharge curve according to the data recorded in the measurement, and save it for comparison in future measurement.
4. The terminal voltage of backward shengyang battery is low when discharging, so the backward battery should be measured in the discharge state.In case of backward batteries, the battery should be charged.
