How to change the lead-acid battery of UPS power supply to lithium battery?

To change the UPS lithium battery, the first thing to do is to calculate the battery capacity of the UPS power supply. 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 the lead-acid battery under the same capacity, do not think about using the same volume of the original UPS lithium battery for replacement. The behavior is not very recommended. 2. Lithium battery Normally, it is not an easy task to have a lithium battery UPS 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 lithium battery packaged into a single lithium battery is the best way to replace the lead-acid battery. 3. Test After the lithium battery is packaged, a number of tests are required for the lithium battery pack for safety. After testing the safety of the lithium battery pack and replacing it with the UPS lead-acid battery, it must 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 lithium battery UPS 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. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
