[Object] To prevent elements in a pack main body and an electronic apparatus from malfunctioning even if the pack main body having an outer shape line-symmetric in up and down directions and left- and right-hand directions is incorrectly attached. [Solving Means] There are provided a pack main bodyinstalling the battery celland a terminal portionconstituted of a plus terminal, a minus terminal, and a control terminalthat are provided on a front surfaceof the pack main body. The plus terminal, the minus terminal, and the control terminalare provided so as to be deviated to one end portionin a width direction of the front surfaceand arranged in an order of the plus terminal, the control terminal, and the minus terminal. The sizes of the control terminal, the plus terminal, and the minus terminalare increased in an order of the control terminal, the plus terminal, and the minus terminalsuch that the control terminalis formed to be the smallest. While being attachable to various electronic apparatuses, the pack main body can ensure a sufficient mechanical strength.

Battery pack

Rechargeable battery

A battery pack includes a pack body that includes a battery cell and that has an external shape substantially symmetric with respect to the horizontal and vertical axes, viewed from a front face on which terminals are arranged, and a terminal unit on the front face. The terminal unit includes a positive terminal, a negative terminal, a control terminal, and a temperature detection terminal for outputting temperature data. The positive terminal and the negative terminal are arranged on one side with respect to a center line in the width direction of the pack body. The control terminal is arranged symmetrically to the temperature detection terminal with respect to the center line in the width direction of the pack body.
