A combination including a battery pack and a battery charger operable to supply a charging current to the battery pack. The lead may include a longitudinally extending body, an electrical conductor, a tube and an electrical component, such as, for example, an electrode for sensing or pacing, a defibrillation coil, a strain gage, a pressure sensor, a piezoelectric sensor, an integrated chip, an inductor, etc. The terminals are arranged with their flat trunks parallel to the plane of the terminal housing part, and are supported by the terminal housing part by allowing the mold to overhang the opposite lateral and longitudinal edges of the trunk of each terminal.
