Abstract

An external power supply (22) powers an electronic device (20) having rechargeable cells (70). The external power supply (22) provides power (26) having a voltage which tracks the rechargeable cells. The voltage of the external power supply preferably tracks with an offset above the voltage (86) of the rechargeable cells. An external power supply type indicating device (130), such as a resistor, indicates to the electronic device the type of external power supply. The external power supply (22) can thus provide power for fast-charge or trickle-charge operations, and charge control circuitry within the electronic device is capable of accurately controlling charge of the rechargeable cells based upon the type of external power supply indicated by the resistor. <IMAGE>
