How to distinguish between good and bad UPS lithium batteries?

How to distinguish between the quality of ups lithium batteries? We usually use professional measuring instruments to determine the quality of lithium batteries, but this special instrument is not something ordinary users can have, so how can ordinary users buy lithium batteries accurately and quickly? How to determine the quality of an UPS lithium battery? In fact, the method is very simple. First of all, it is simple to judge from the appearance, just like seeing, smelling, asking, and cutting in Chinese medicine. The first thing to look at is the integrity of the appearance, such as whether the appearance of the lithium battery is deformed or raised. If this happens, the internal chemical structure of the lithium battery has been destroyed, which is the first choice to be excluded. In addition to the observed deformation conditions, whether there is any leakage, cracking, rupture, burning or fluid leakage inside the threaded sleeve joint, etc., the battery usually has an important quality problem of the battery, not only the lithium batteries with defects in appearance cannot The choice, including it is the battery manufacturer's choice is not recommended, in case there are safety accidents and various shortcomings during use. In addition to observing the completeness of the appearance from the surface, the internal load must also be measured. When confirming that there is no abnormal appearance, the next step under normal conditions is that the UPS lithium battery is in working mode and has a certain load-bearing capacity. If the lithium battery discharge time is abnormal or has not returned to normal, the charging time standard specifies the standby time. The battery has been aging, and can no longer satisfy the daily use of lithium batteries.
