How to judge the quality of lithium-ion battery UPS

Regarding the pros and cons of lithium-ion battery UPS, our usual practice is to use professional measuring instruments for appraisal, but this kind of special-purpose instrument is not something ordinary users can have. The steps are as follows: ①In fact, the essentials are very simple, the first is simple Judging from the appearance, it is like communicating with each other through sight, smell and inquiries when a Chinese medicine doctor sees a doctor. When investigating, we must first look at the integrity of the appearance. For example, whether the appearance of the lithium-ion battery UPS is deformed or raised or caused by the environment. If this situation occurs, the internal chemical structure of the lithium-ion battery has been shattered, and it is the number one choice to remove Queue. ②In addition to investigating the deformed environment, it is also necessary to see if there is any leakage, splitting, bursting, scorching, or leakage of internal liquid from the screw connection. All such batteries have major quality problems, not just the appearance. The defective batch of lithium-ion batteries cannot be selected, including the batteries of the same model and the same manufacturer, and the selection is not initiated, in case there are security changes and various obstacles in the process of use. ③In addition to visualizing the completeness of the appearance from the appearance, it is also necessary to conduct a load measurement on the inside. When it is determined that there is no abnormal environment in appearance, the next step is to put a certain amount of load on the lithium-ion battery UPS in an environment where the lithium-ion battery UPS is in the working mode. If the discharge time of the lithium-ion battery cannot reach the normal discharge time If the charging time is prosperous and the standby time specified by the normal scale cannot be returned, it means that the battery is aging, and people are no longer satisfied with the daily use of lithium-ion batteries.
