BATTERY CHARGER WITH COOLING AND SEALING CONSTRUCTION

A charger for use with a rechargeable battery includes a housing, electrical components, a connector port, a heatsink, and thermally conductive filler material. The housing includes a battery interface slidably receiving the rechargeable battery. The electrical components are disposed in the housing. The electrical components generate heat. The connector port is electrically coupled to the electrical components. The heatsink is disposed in the housing. The heatsink includes a cavity. The thermally conductive filler material at least partially fills the cavity. The thermally conductive filler material contacts both the electrical components and the heatsink.
