Abstract: In a battery charger cradle, a battery incorporated in a battery built-in device is charged by electric power induced to an induction coil. The cradle includes a primary coil for inducing electromotive force to the induction coil, a casing having a top plate atop of which the battery built-in device is placed, a movement mechanism for moving the primary coil along an inner surface of the top plate, and a position detection controller for detecting a position of the battery built-in device placed on the top plate and controlling the movement mechanism to bring the primary coil closer to the induction coil in the battery built-in device. When the battery built-in device is placed on the top plate, the position detection controller detects the position of the battery built-in device, and the movement mechanism moves the primary coil closer to the induction coil in the battery built-in device.

Abstract: The type of the attached batteries is determined by decision switch mechanisms. A protruding region is established in the attachment section to provide contact between charging terminals and the electrodes of short batteries. A stepped shelf region is established with the protruding region, and long batteries are mounted inside the attachment section on top of the stepped shelf region. Charging terminals are disposed in electrode alignment surface of the stepped shelf region, and decision switch mechanisms are housed inside the stepped shelf region. A decision switch mechanism is a switch that switches when pressed by the battery electrode of either a long battery or a short battery loaded in the attachment section. The control circuit switches charging current between a first charging current and a second charging current depending on the OFF or ON state of the decision switch mechanisms.

Abstract: A charger including a first charging terminal that contacts one of positive and negative terminals of a rechargeable battery to charge the battery; and a second charging terminal that is opposite in polarity to the first charging terminal electrically connected to a charging circuit. The first charging terminal has a nip portion that is formed by bending a metal plate in a folded manner such that parts of the metal plate are opposed. A temperature sensor is disposed in the nip portion. The temperature sensor disposed in the nip portion detects the battery temperature through the intermediary of the metal plate of the first charging terminal in contact with the terminal of the rechargeable battery.

Abstract: The battery charger is provided with temperature detection sections 12 to contact and detect the temperature of AA batteries 2A and AAA batteries 2B loaded in a battery pocket 3, and a charging circuit to detect battery temperature and control battery 2 charging. The battery charger is provided with AA battery 2A holders 11, which are circular openings 13 in the case 1, and AAA battery 2B holders 11, which are flexible arches 14. An AAA battery 2B is inserted into a flexible arch 14 and retained in a fixed position in the battery pocket 3. An AA battery 2A is not inserted into a flexible arch 14, but rather moves the flexible arch 14 causing it to incline, and is inserted into a circular opening 13 for retention in a fixed position in the battery pocket 3. The battery charger charges batteries 2 set in fixed positions in the battery pocket 3 while detecting battery 2 temperature via the temperature detection sections 12.
