Analysis of the way to replace lithium battery with UPS power supply battery

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 based on 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 Under normal circumstances, 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. Test After the lithium battery is packaged, a number of tests on the UPS lithium battery are required for safety. After testing the safety of lithium batteries and replacing them with lead-acid batteries, they must also be tested. For the sake of safety, it is always correct to conduct more tests. 4. After a number of tests have been carried out to confirm that the lithium battery has successfully replaced the lead-acid battery, the final assembly can be carried out. Reassemble the UPS battery according to the correct method to restore the integrity of the appearance, and finally conduct an overall test. After the test is completed, it can be regarded as a real replacement. 5. Check the battery pack and UPS power supply. After replacing the battery, use a multimeter to check the total voltage of the battery pack, the positive and negative poles of the battery pack, and the neutral wire connection. After ensuring that the UPS power supply battery host is normal, close the switch of the battery pack to restore the UPS uninterruptible power supply system to normal operation.
