Cylindrical AAA alkaline dry battery

摘要

The invention relates to a cylindrical AAA alkaline dry battery including: a positive terminal protruding from one end face of the alkaline dry battery; a negative terminal protruding from the other end face; and an external label covering the alkaline dry battery. The diameter Dp (mm) and protruding height Hp (mm) of the positive terminal and the diameter Dn (mm) and protruding height Hn (mm) of the negative terminal satisfy the relation (1): 2.5≦Dn−Dp≦4.1 (1), and the relation (2): 0.8≦Hp−Hn≦1.1 (2). This permits easy and reliable identification of the polarities of the terminals, making it possible to provide a cylindrical AAA alkaline dry battery which is unlikely to be installed reversely.
