How to replace the UPS battery with a lithium battery? Preliminary preparations: After the notification of the battery replacement work, the battery replacement executive engineer will go to the site to make preparations: ensure the input power supply of the UPS host, the registration inspection of the new and old batteries, and the smoke probe of the fire protection system in the computer room Sealing, preparing carbon dioxide fire extinguishers and other related work. Before replacing the lithium battery, make relevant registration records for the 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. 1. Capacity calculation To change the UPS lithium battery, the first thing to do is to calculate the battery capacity. Calculate the capacity of the lithium battery to be replaced according to the capacity of the original lead-acid battery. Although the volume of the lithium battery is smaller than that of the lead-acid battery under the same capacity, do not think about using the original lithium battery UPS with the same volume of lithium battery to replace , This behavior is not very recommended. 2. Lithium battery pack Normally, it is not easy to have a lithium battery with the same capacity as the original UPS lead-acid battery. Under normal circumstances, hands-on people need to connect a single small-capacity lithium battery in series and parallel and install safety protection components to form a lithium battery pack. This is the best way to replace a lead-acid battery with a lithium battery pack packaged from a single lithium battery. 3. Testing After the lithium battery pack is assembled, a number of tests are required for the UPS lithium battery pack for safety. After testing the safety of the lithium battery pack and replacing it with the lead-acid battery, testing should also be performed. For the sake of safety, it is always right to perform more testing.
