System and method for information handling system battery charge protection and fault alarm

Abstract

An information handling system battery has first and second protective circuits to detect and address faults for a first charge applied from an external power source to an integrated charger and a second charge applied from a charger of an information handling system to battery cells. If the first protective circuit detects a fault associated with the integrated charger, charging of the battery cells is still supported by inserting the battery in an information handling system. If the second protective circuit detects a fault, the battery becomes inoperative by disconnecting the battery cells. An indicator, such as LEDs on the battery casing, indicates whether a soft or hard fault has occurred.
