With regard to the advantages and disadvantages of lithium-ion battery UPS, our usual practice is to use professional measuring instruments for identification, but this special instrument is not available to ordinary users. The steps are as follows:

① In fact, the key is very simple. First of all, it is simple to judge from the appearance, just like the communication when seeing a doctor in traditional Chinese medicine. During the investigation, the first thing to look at is the integrity of the appearance, such as whether the appearance of the lithium ion battery UPS is deformed or bulged. If this situation occurs, it means that the internal chemical structure of the lithium ion battery has been broken, and it is the first queue to be unselected.

② In addition to investigating the deformation environment, we also need to see whether there is any environment such as leakage, cutting, cracking, burning, and internal liquid leaking from the screw joint. All these batteries are batteries with major quality problems. Not only the lithium ion batteries with defects in appearance are not available for selection, including batteries of the same model and manufacturer, In case of peaceful changes and various obstacles in the process of use.

③ In addition to the integrity of the external appearance, the internal load measurement should also be carried out. When it is confirmed that there is no abnormal environment in the appearance, the next step is to make the lithium-ion battery UPS bear a certain amount of load when it is in the event mode. If the discharge time of the lithium-ion battery cannot reach the normal discharge time, or if the charging time is rich, and still cannot return to the standby time defined by the normal scale, it means that the battery has aged, We can no longer be satisfied with people's daily use of lithium-ion batteries.
