A battery pack having a detection recess formed along a center line of a bottom surface arranged such that the detection recess is engaged with a convexed portion of a battery charger. Therefore, whether or not the battery pack is properly attached to the battery charger can easily be detected by the inclination of the battery pack about the center line. Further, a battery pack is arranged such that an aperture is formed on an outer surface of the battery pack and an output terminal is inwardly disposed on the aperture. Therefore, damage to the batteries in the battery pack caused by a short-circuit resulting from products made of conductive metal material such as a key ring, necklace, or chain contacting both of the output terminals, as occurs when terminals are disposed on the outer surface of the battery pack, can be prevented. Furthermore, the battery pack includes apertures with output terminals disposed therein for discharging dust or the like away from the terminals into the interior of the casing or out of the casing through a hole. Therefore, the accumulation of dust or the like within the apertures and upon the output terminals is prevented.
