Abstract: An electrical apparatus houses batteries mounted on a printed circuit board (PCB) via conducting tabs with cylindrical insertion sections. The cylindrical insertion sections fit into circular holes in the PCB or into cylindrical sockets soldered into PCB holes. Battery attachment can either be permanent by soldering tabs into the holes or removable by tab insertion into sockets. Removable attachment allows easy battery recovery for recycling. Utilizing the elasticity of sheet metal and cylindrical shaped tabs provides more secure battery attachment resulting in good shock and vibration resistance, and contact over a cylindrical surface insures good electrical connection.
