AA Dry Battery.Backup UPS uninterruptible power supply discharge process and precautions

　　Backup UPS uninterruptible power supply discharge process and precautions. In the daily use of the backup UPS power supply, the service life of the UPS can be extended only by frequently discharging the UPS. Generally speaking, the UPS power supply battery needs to be charged and discharged at least once every three months. Now, let’s talk to you about it. Precautions and steps during charging and discharging.

　　Discharge process of backup UPS uninterruptible power supply

　　1. Check to disconnect the UPS mains input circuit breaker and discharge the UPS. The load during discharge should not exceed 60% of the total load of the UPS;

　　2. After switching to the battery pack for power supply, the discharge time is determined according to the length of battery power supply (generally the battery pack discharges for 30 minutes to 1 hour);

　　3. Check the inverter output light and LCD screen display on the front panel of the backup UPS;

　　4. Measure the UPS output voltage and battery pack voltage;

　　5. After the host discharges and alarms, close the UPS mains input circuit breaker, and then observe whether the UPS is running normally.

　　Note: For normal use of the UPS power supply, it is best to discharge it once every three months to six months. Failure to discharge it for a long time may easily cause battery damage. Under normal circumstances, discharging the backup UPS power supply every three months can not only ensure the service life of the UPS battery, but also ensure the longest use of its backup time. In order to effectively extend the service life of the UPS, we must pay attention to the discharge of the battery to ensure that the UPS battery can always be in efficient working condition.

　　The specific steps to discharge the UPS power supply are: first connect the output end of the UPS power supply to 50% of the load, and then disconnect the mains power supply to keep the UPS power supply in the discharge working state. During the discharge process, the voltage at both ends of the UPS power supply is changed. Monitor, and once it is found that the terminal voltage drops to about 10.5V, turn on the mains power to charge the UPS battery continuously for about 10 hours, so that the activity of the UPS battery will not be affected.

　　Precautions for discharge of backup UPS power supply

　　1. Before discharging, you must first understand how long the backup UPS power supply can last, so that you can be prepared when discharging to prevent the discharge from reaching the backup time, causing load downtime and equipment failure. of damage.

　　2. If the UPS battery can be seen, first visually inspect the battery to see if there is any obvious deformation or leakage damage.

　　3. If the backup UPS uninterruptible power supply itself has the automatic discharge function, it is recommended to let the UPS uninterruptible power supply perform a discharge by itself first, so that you can initially determine whether the battery has the discharge function.

　　4. During artificial discharge, please always pay attention to the drop in battery voltage of the UPS so that you can connect to the mains input at any time.

　　5. When discharging the backup UPS for the first time, it is not necessary to completely discharge the battery capacity. Here it is only necessary to discharge it to 70% of the rated capacity. Discharging only serves to activate the battery. Extend the life of ups battery.

　　6. If it is a high-power UPS power supply, generally the rectifier and bypass input switch are designed independently. It is recommended to turn off the rectifier switch instead of turning off the user's mains input switch to prevent the UPS from immediately switching to the mains in case of battery discharge. Works in bypass operating mode.
