An smart battery apparatus for connecting a smart battery to a portable computer system includes a primary smart battery and a secondary smart battery, each having a first connector and a second connector installed at an exterior for connecting the secondary smart battery to the primary smart battery. A smart battery selecting unit is also included for selecting the primary smart battery or the secondary smart battery and controlling the selected battery so as to supply power to a portable computer system. A system power supply unit supplies the power selected by the smart battery selecting unit and appropriate power for operating the system. A SM BUS (System Management Bus) host is checking operation states or operation information of both smart batteries and requesting a charge state of each smart battery. An AC/DC adapter receives AC power from an AC power source and outputs DC power, and a charging unit receives the DC power from the AC/DC adapter and supplies power to change the primary smart battery or the secondary smart battery.
