Abstract:
1. A method for charging a battery in an information handling system the method comprising: coupling a charge controller and the battery to the information handling system (IHS), wherein the charge controller provides a plurality of charging modes comprising a first mode, a second mode, and a third mode; incorporating the plurality of charging modes into a charging mode menu, wherein the charging mode menu is provided by a power on self test (POST) menu or an operating system (OS) utility menu of the IHS; prompting a user to select a desired charging mode from the charging mode menu of the POST menu or the OS utility menu of the IHS; constant rate charging the battery in the first mode when the first mode is selected, wherein a charge voltage and a charge current are constant for fast battery charging regardless of battery performance and battery saving; and dynamically charging the battery when either the second mode or the third mode is selected, wherein the charge current changes dynamically based on battery temperature for improved battery performance and battery saving; wherein the first and second modes are fast charging modes relative to the third charging mode and the second mode is a faster charging mode relative to the first charging mode, and in which second mode the charge current is set at a first predetermined level if the battery temperature is in a first range and the charge current is set at a second predetermined level if the battery temperature is not in the first range.
