Abstract
A battery pack is positively prevented from being loaded in an incorrect manner in a battery loading portion inappropriate for the battery pack. To this end, the battery pack includes a battery cell, a casing housing this battery cell, and first to third output terminals outputting the power of the battery cell. The casing has a front surface on which the output terminals are arranged, and a bottom surface extending substantially at right angles to the front surface. A discriminating recess having a discriminating groove is formed at a mid portion of the bottom surface. The discriminating recess and/or discriminating groove are sized and positioned to receive the discriminating projections in some battery loading portions, but not those in other battery loading portions.
