What are the problems when different capacity batteries are used together?
If different capacities or old and new batteries are used together, leakage and zero voltage may occur. This is because in the process of charging, the capacity difference leads to some batteries being overcharged, some batteries not full, some batteries with high capacity are not fully discharged while others with low capacity are overcharged. In such a vicious cycle, the battery is damaged by leakage or low (zero) voltage.
According to such rules, manufacturers need to ensure the consistency of battery capacity, voltage and internal resistance when producing cores.
