Abstract
A universal inductive battery charger is described including an inductive battery charger having a charging coil which creates magnetic flux lines when the charging coil is energized. The battery charger is adapted to charge a battery pack, through induction, when the rechargeable battery pack is placed on the battery charger. The battery pack includes a pick-up coil which will have an electrical current induced therein when the battery pack is positioned adjacent the battery charger. The battery pack includes a circuit for rectifying the induced current in the pick-up coil to charge the battery cells in the battery pack.
