Abstract
Even when an ambient temperature of a battery housed in a battery pack is detrimentally low, the battery is capable of performing its normal discharge operation, and thereby preventing the available period of time of an electronic device powered by the battery from decreasing due to such detrimentally low ambient temperature. In the battery pack: a positive plate and a negative plate are in a side portion of the battery; a heating element receives therein the battery, wherein the battery has both the positive plate and the negative plate electrically connected with a control circuit board, the control circuit board being electrically connected with the heating element through a pair of lead wires, wherein these components are assembled into an assembly which is inserted into a lower casing in a condition in which the control circuit board is projected outward from the heating element, so that the control circuit board is mounted on a board support base provided with a plurality of terminal output ports; and, an upper casing is mounted on both the assembly and the lower casing to cover them from above.
