About the lithium-ion battery UPS is good, our usual practice is to use a professional measuring instrument to determine, but this dedicated instrument is not the general user can have, the steps are as follows: 1 In fact, it is simple, first is simple. Judging from the outside, if the Chinese medicine is looking at the same time. First, you must first look at the integrity of the appearance, such as the appearance of the lithium ion battery UPS, or convex, etc.

, if this is the case, the internal chemical structure of this lithium-ion battery has been destroyed, belongs to the number one to exclude selection Row. 2 In addition to the observation of the deformation, there is still a case where there is no leakage, breaking, cracking, charring or screw connection, usually such a battery is a battery with major quality problems, not just the appearance. This batch of lithium-ion batteries with defects cannot be selected, including and it does not propose for the battery with the same model, to prevent safety accidents and various faults in the process of use.

3 In addition to the integrity of the appearance from the surface, it is necessary to carry the measurement internally. When it is determined that there is no abnormal condition occurs, the next step is to carry a certain amount of load in the case where the lithium ion battery UPS is in the working mode, and if the discharge time of this lithium ion battery cannot reach normal discharge time or charging After the time is sufficient, you cannot reply to the normal standard specified by the normal standard, indicating that this battery is aging, it is no longer able to meet the daily use of lithium-ion batteries.
