PURPOSE:To prevent accident occurrence even a short circuit is generated between outside terminals in carrying a battery pack itself, by devising an idea so that voltage can be generated first between the outside terminals of the battery pack through connecting the battery pack to exclusive electronic equipment. CONSTITUTION:A battery pack 1 incorpotates a battery 4, is provided with a pair of outside terminals 2 and 3 of positive and negative electrodes connected to the battery 4, and is constituted so that the outside terminals 2 and 3 can be connected respectively to electric terminals 8 and 9 provided on the exclusive equipment 7 when an mounted on the exclusive equipment 7. An intermittent means (e.g. lead switch) 5, intermitting a circuit, is provided in a circuit, connecting between the battery 4 and one-side of an outside terminal, and when the battery pack 1 is mounted on the equipment 7, the lead switch 5 becomes a connected condition by a connecting means (magnet) 6 provided on the equipment 7, causing the voltage of the battery 4 between the outside terminals 2 and 3. |
