What are the methods and steps to replace UPS batteries

1. After receiving the notification that the UPS battery can be replaced, the battery replacement executive engineer went to the site to make preparations: to ensure the input power of the UPS battery host, the registration inspection of the new and old batteries, the sealing of the smoke detectors of the fire protection system in the computer room, and the preparation of carbon dioxide Fire extinguishers and other related work. Before replacing the battery, make relevant registration records for the lithium battery UPS host, old battery packs, battery monitors and other equipment, especially the placement of each layer of batteries and the wiring of the battery monitors. Mark and draw the connection diagram. Ensure that the effect after the battery pack is replaced is consistent with the original situation. 2. After everything is ready, replace the UPS battery to solve the problem, disconnect the connection switch between the UPS host and the battery pack, disconnect the lithium battery UPS host and the battery pack, to ensure the safety of the staff when replacing the battery. Disassemble the batteries of the original battery pack. The battery replacement executive engineer is responsible for the disassembly of the batteries, and the relevant auxiliary technicians carry out the handling of new and old batteries. When disassembling the old battery, place the disassembled battery cable and battery terminal screws neatly in a box to ensure tidiness and cleanliness in the equipment room. After removing the old battery, place the old battery and the old battery rack neatly in the position specified by Party A. Place the new battery rack assembly in the designated position, and start to install the new battery at the same time. Place the new battery on the battery rack so that the position and direction of the new battery on the battery rack are adjusted best. After connecting a set of batteries, check whether the connecting wires of the battery terminals are firm; check whether the total voltage of the battery pack is normal, etc., and the positive and negative poles of the batteries must be connected correctly. 3. After replacing the battery, use a multimeter to check the total voltage of the UPS battery pack, the positive and negative poles of the battery pack, and the neutral wire connection. After ensuring that the battery pack and the lithium battery UPS host are normal, close the battery pack switch to restore the UPS uninterruptible power supply system to normal operation. Then test the UPS's working voltage, current, charging voltage, working status, etc. and make a record. One person observes whether the parameters in the LCD display of the host are the same as the actual ones, and the battery time parameters are adjusted and set to ensure that the lithium battery UPS power supply will not give false alarms during the normal life. After the UPS host is debugged normally, turn off the input power switch of the UPS host to simulate the interruption of the mains power failure, and detect whether the UPS system can normally be converted from the mains power to the battery pack backup power supply to ensure the normal operation of the equipment in the machine room cabinet. 4. After the UPS battery replacement work is completed, clean the UPS room and clean up debris to ensure a good environment in the UPS room. Restore the preparatory work done in the equipment room before the battery replacement. Moreover, the new battery pack should be charged for about 24 hours to ensure that the new battery overflows with power.
