  • BATTERY CONTACT MECHANISM FOR A BATTERY CHARGER
    Publication number: 20080185992
    Abstract: An apparatus includes a housing having a first wall and a sliding tray having a second wall that is generally parallel to the first wall. The sliding tray slides between a retracted position and an extended position in which the first and second walls define a battery receiving region in the sliding tray. The apparatus further includes a first battery contact provided in the first wall and a second battery contact proximate to the second wall. The first and second battery contacts electrically communicate with battery charging circuitry, and the second battery contact slides relative to the second wall in a direction that changes a battery receiving distance between the first and second battery contacts.
