How to judge the quality of ups lithium battery

For the quality of lithium batteries, our usual practice is to use professional measuring instruments to judge, but this special instrument is not available to ordinary users, so how should ordinary users buy accurate and fast when purchasing lithium batteries? Judging the quality of an ups lithium battery?

In fact, the method is very simple. The first step is to simply judge from the outside, just like the Chinese medicine doctors look at the disease. When observing, we must first look at the integrity of the appearance, such as the appearance of the lithium battery, whether there is deformation or protrusion, etc. If this situation indicates that the internal chemical structure of the lithium battery has been destroyed, it is the number one to exclude the selection. In addition to observing the deformation, it depends on whether there is leakage, cracking, cracking, burning, or leakage of internal liquid at the screw joint. Usually, this battery is a battery with significant quality problems, not just the appearance. The defective lithium battery of this batch cannot be selected, including the battery of the same manufacturer and the same manufacturer. It is also not recommended to prevent safety accidents and various faults 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.
