Battery quality control for after-sale
All of Melsen battery cells in a pack are with very high consistency.In a pack, each cell has its ownsole electronic code(ID number) for quality control after-sale. Assume one cell in a pack is damaged in any reason after several years later, we could provide a exactly same cell to the client to replace this damaged one(same voltage, capacity, impedance,etc.), in order to make sure all of the cells in this pack with very high consistency. Melsen has a strong system working for this.
