ABSTRACT:
The present invention is directed to a battery pack in which it can be detected with ease whether a battery pack is properly attached to a battery charger or a power supply of electrical machinery and apparatus. A battery pack (10) that accommodates therein a battery includes at its central bottom surface a detection aperture (104) that is engaged with an engagement portion formed at a connection portion of a battery charger or electrical machinery and apparatus to which the battery pack is connected to thereby detect the kind of the battery. Also, the battery pack (10) includes on its bottom surface a detection aperture (106) that is engaged with an engagement portion formed at a connection portion of the battery charger or electrical machinery and apparatus to which the battery pack is connected to thereby detect an electric power output amount of the battery.
