The present invention entails a battery identification system to be utilized by cellular telephones, battery chargers, and other electrical devices for identification of the battery types employed within such devices. The battery identification system comprises a battery type identification circuit that includes one or more input switches that are coupled to a voltage divider network that is made up of a series of voltage divider segments. Each voltage divider segment is designed to produce a signal that is indicative of the on/off state of a particular input switch. To actuate the input switches, the employed battery is provided with one or more switch actuators, where the position and spacing of the switch actuators on the battery in effect uniquely identifies the battery type. Various switching and actuating configurations are contemplated, including mechanical, galvanic, magnetic, and optical systems.
