In all occasions where lead-acid batteries are used in series, the single batteries used in series need to be grouped. The matching of batteries requires high consistency of individual batteries, and the premise of matching is the same brand, same model and same batch. The rapid degradation of battery pack performance due to poor battery consistency has been widely recognized as an objective existence. When individual or partial battery cells of the battery pack deteriorate, no one, no theory or actual data support the case that replacing a deteriorated battery cell can ensure the performance of the battery pack. The traditional practice is to discard the entire battery pack without exception. The use of battery activation technology can restore the performance of some deteriorated battery packs and continue to use them. However, in the face of complete failure of individual battery cells in the battery packs, the whole battery packs need to be scrapped. Therefore, it is necessary to study the comprehensive utilization technology of lead-acid batteries based on the principle of " reduction and resource utilization "!
