18650 battery 3.7v 2000mah

　　How to replace 18650 battery 3.7v 2000mah and what are the installation steps?

　　1. 18650 battery 3.7v 2000mah replacement method

　　1. After receiving the notification that the UPS power battery can be replaced, the battery replacement implementation engineer went to the site to make preparations: ensuring the input power supply of the UPS host, registration and inspection of new and old batteries, sealing of the smoke detector of the fire protection system in the machine room, and preparing carbon dioxide Fire extinguishers and other related work.

　　2. Before replacing the battery, make relevant registration records for the UPS host, old battery pack, battery monitor and other equipment, especially the placement of batteries on each layer and the wiring of the battery monitor. Mark them and draw a connection diagram. Ensure that the effect after battery pack replacement is consistent with the original condition.

　　3. After everything is ready, replace the 18650 battery 3.7v 2000mah, disconnect the connection switch between the UPS host and the battery pack, and disconnect the UPS host and battery pack to ensure the safety of the staff when replacing the battery. The batteries of the original battery pack are disassembled. The battery replacement implementation engineer is responsible for the battery disassembly, and the relevant auxiliary technicians carry out the transportation of new and old batteries.

　　4. When removing the old battery, place the removed battery cables and battery terminal screws neatly in boxes to ensure that the computer room is tidy and clean. After disassembling the old batteries, place the old batteries and old battery racks neatly in the locations specified by Party A. Place the new battery rack assembly in the designated position and start installing 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 can be adjusted optimally.

　　5. After connecting a set of UPS batteries, check whether the battery terminal connections are firm; check whether the total voltage of the battery pack is normal, etc. The positive and negative poles of the batteries must be connected correctly.

　　6. After replacing the 18650 battery 3.7v 2000mah, use a multimeter to check the total voltage of the battery pack, the positive and negative poles of the battery pack, and the wiring of the neutral wire. After ensuring that both the battery pack and the UPS host are normal, turn off the battery pack switch to restore the UPS uninterruptible power supply system to normal operation. Then detect the working voltage, current, charging voltage, working status, etc. of the UPS and keep records. One person should observe whether the parameters in the host LCD display are consistent with the actual ones, and debug and set the battery time parameters to ensure that there will be no erroneous alarm prompts during the normal life of the battery.

　　7. After the UPS host is debugged normally, disconnect the input power switch of the UPS host, simulate a mains power failure, and test whether the UPS system can normally switch from mains power to battery backup power supply to ensure the normal operation of the equipment in the computer room cabinet.

　　8. After the UPS power battery replacement work is completed, clean the UPS room and remove debris to ensure a good environment in the UPS room. Resume the preparation work done in the computer room before replacing the 18650 battery 3.7v 2000mah.

　　2. Installation steps

　　1. After the equipment arrives at the site, confirm the UPS model, battery model, and quantity to be installed in order to prepare the tools, power cords, and battery cables to be carried.

　　2. Prepare the tools required for installation: Here you need an impact drill, several expansion wires, and basic tools for electricians.

　　3. Install the UPS on the south wall of the workshop.

　　4. Install the battery cable.

　　5. Host installation and wiring.

　　6. Start the host.

　　7. Connect the load.

　　8. Clean the installation site and clean the packaging cartons.

　　9. Keep the accompanying accessories (instructions, certificates), and do simple training on switching on and off, maintenance, etc.
