　　How to replace UPS battery with 18650 lithium 3.7 battery?

　　Preparatory work: After receiving the battery replacement notice, the battery replacement implementation engineer went to the scene to carry out preparation work: ensuring the input power supply of the UPS server, registration and inspection of new and old batteries, sealing of smoke detectors of fire protection equipment in the computer room, preparation in advance Carbon dioxide fire extinguisher and other related work. Before replacing lithium batteries in UPS servers, old battery packs, battery monitors and other equipment, keep relevant records, especially the placement of batteries on each layer, the wiring of battery monitors, label them, and draw connection diagrams. . Ensure that the actual effect of the rechargeable battery after replacing the battery is consistent with the original battery response.

　　1. Capacity Calculation After replacing the UPS 18650 lithium 3.7 battery, the first thing that needs to be done is to calculate the battery capacity. Calculate the capacity of the 18650 lithium 3.7 battery that needs to be replaced based on the capacity of the original lead-acid battery. Although the capacity of the 18650 lithium 3.7 battery is smaller than that of the lead-acid battery at the same capacity, don't worry about replacing it with a 18650 lithium 3.7 battery of the same capacity as the UPS. Such behavior is inappropriate. excellent.

　　2. 18650 lithium 3.7 battery pack. Generally speaking, it is not easy to have a 18650 lithium 3.7 battery with the same capacity as the original UPS lead-acid battery. Generally speaking, masters with hands-on skills need to connect individual small-capacity lithium batteries in series and parallel by themselves, and install safety protection components to form a 18650 lithium 3.7 battery pack. This type of 18650 lithium 3.7 battery pack consists of an independent 18650 lithium 3.7 battery and is the best alternative to lead-acid batteries.

　　3. Inspection After the 18650 lithium 3.7 battery package is assembled, for safety reasons, the UPS 18650 lithium 3.7 battery package must be inspected several times. Carry out safety inspections on lithium batteries, and after replacing lead-acid batteries, safety inspections must also be carried out. In order to better consider safety, it is always right to do more inspections.

　　4. Installation. After several tests, it was confirmed that the replacement of lead-acid batteries with lithium batteries was successful, and the overall home improvement could be carried out only after the test. Reassemble the UPS battery according to the correct method to restore the consistency of the appearance, and then carry out a comprehensive inspection. Only after the inspection is completed can it be regarded as the actual replacement.

　　5. Check whether the battery pack and UPS power supply system are normal. After the battery replacement work is completed, use a digital multimeter to check the total voltage status of the 18650 lithium 3.7 battery pack, as well as the positive and negative and neutral point connection status. After confirming that both the battery and the UPS battery server are working normally, turn off the battery power switch and the UPS power system will resume working.
