Because battery scrapping is a technical concept, it doesn't mean it can't be used. According to the industrial battery standard, if the actual capacity of the battery falls below 80% of the nominal capacity, it will be considered as scrapped; There is no clear index for civil batteries. Usually, when describing the service life of KUDA electronic storage battery, the end point is that the actual capacity drops to 60% or 50% of the nominal capacity, which is understood as scrapping. However, the batteries that have fallen to the scrap point often have the characteristics that the index begins to deteriorate, the capacity accelerates to decline, and the performance difference between the single battery power supply schemes in a group of batteries begins to expand obviously. Whether it can be used or not, it is recommended to put it in the designated battery recycling place.
