Abstract: A power supply apparatus includes a generator, lead-battery, and second-battery. Open-circuit voltages and internal resistances of the batteries are determined so that: there is a point, where the open-circuit voltage of the second-battery coincides with that of the lead-battery, in a region on a smaller-residual-capacity side relative to a range of use in an entire-residual-capacity range of the second-battery; the open-circuit voltage of the second-battery is larger than that of the lead-battery in the range of use of the second-battery; the internal resistance of the second-battery is smaller than that of the lead-battery in a charging state of the generator; and a terminal voltage of the second-battery in a state where a maximum charge current is passed through the second-battery is smaller than a regulated voltage in a power-generation state of the generator. An opening/closing section is closed in at least one of a power-generation state and a load-activated state.
