A battery charging apparatus, which charges a secondary battery such as an Ni-Cd battery being used for a battery-driven equipment such as a VTR camera, is provided with a first loading unit for only charging a loaded battery and a second loading unit for charging a loaded battery, for discharging the charged battery, for measuring the capacity of the discharged battery, and for displaying the measured capacity by four steps of its percentage, and which is capable of using either of the both loading units according to the qualities of the battery characteristics of the battery. In this battery charging apparatus, a new battery or a battery with good battery characteristics substantially similar to the new one are charged in the first loading unit and an old battery or a battery with inferior battery characteristics are charged in the second loading unit. The former unit can charge the battery in a shorter time and the latter one can recover the better battery characteristics by repeating the charging and discharging operation to the battery with inferior battery characteristics a few times.
