How to distinguish the stand or fall of ups lithium battery?

Source: 2020 - 04 - 12 21:37 hits: time how to distinguish the stand or fall of lithium battery ups for the quality of the lithium battery, we usually use professional measuring instrument to determine, but this kind of special equipment is not ordinary users can have, so ordinary users how to accurately and fast when buying lithium battery to determine a ups to the quality of the lithium battery? Method actually very simple, first of all, from the appearance simple judgment, just like watching, auscultation and olfaction, inquiry, and pulse-taking and palpation of traditional Chinese medicine. First is the integrity of the appearance, such as whether the appearance of the lithium battery deformation or protuberance. If this happens, the chemical structure of lithium battery inside has been destroyed, this is the first choice of excluded. In addition to the observed deformation conditions, and if there is any leakage, burst, burst and burning or thread casing joint internal fluid leakage, and so on, there is usually a battery of the main quality problems, not only has this batch of lithium battery can't choose the appearance defects, including it's battery manufacturers choose is not recommended, in case appeared in the process of using safety accident and all kinds of faults. In addition to from the appearance of the integrity of the degree of surface observation, also need to internal load measurement. Determine appearance without exception occurs, usually under the condition of the next step is to UPS lithium battery is in work mode has certain bearing, if lithium battery discharge time is not the normal discharge time or still not back to normal after the standby time of charging time standard, which means that the battery has been aging, can't satisfy People's Daily use of lithium ion batteries. anchor
