Abstract
A battery charger with varying applied voltage and varying series resistance invoked in response to battery charge level provides an optimizable multipart load line for charging. The multipart load line may be programmed into a memory within the battery charger, and thereby common design battery chargers may be configured with optimized multipart load lines for diverse batteries. Programming access can be over the charge current output terminal for both one-wire communication and programming high voltage for EPROM programming.
