How to judge the quality of ups lithium batteries

It is common practice to judge the quality of lithium batteries using professional measuring instruments, but this kind of special instrument is not available to ordinary users. So how can the average user accurately and quickly judge the quality of an ups lithium battery when buying a lithium battery?

In fact, the method is very simple. The first is to judge from the appearance simply, just like the Chinese medicine doctor's eyes and ears. When observing, first look at the integrity of the appearance. For example, if the appearance of a lithium battery is deformed or raised, the appearance of this condition indicates that the internal chemical structure of the lithium battery has been destroyed and it is the number one need to exclude the selection. In addition to observing deformation, it is also necessary to see whether there is a leak, a rupture, a burst, a scorch, or a leakage of internal liquid at the screw connection. Usually this type of battery is a battery with a major quality problem. This batch of lithium batteries that have defects in appearance can not be selected, including batteries of the same type as it is, nor is it recommended to select them in case of safety accidents and various failures during use.

In addition to the completeness of the appearance from the surface, it is also necessary to carry out the on-board measurement. When it is determined that there is no abnormality in appearance, the next step is usually to have a certain amount of load when the UPS lithium battery is in the working mode. If the discharge time of the lithium battery cannot reach the normal discharge time or the charging time is sufficient. After that, it still can't return to the standby time specified by the normal standard, which means that the battery has been aging, and can no longer meet people's daily needs for lithium batteries.
