Can Batteries of Different Capacities Be Used in Combination?

If you mix old and new batteries or batteries of different capacities, liquid leakage and zero voltage may occur. This is due to the difference in capacity during the charging process. And it causes some batteries to be overcharged. Some batteries are not fully charged. The high battery is not fully discharged, while the low capacity battery is over-discharged. In such a vicious circle, the battery is damaged and leaks or has a low (zero) voltage.
