Abstract: A battery pack for an information handling system includes a battery cell configured to provide current to the information handling system, and a battery management unit including an output to the information handling system. The output provides a maximum continuous current (MCC) indication and a peak power (PP) indication. The battery management unit determines an amount of current that the battery cell provides to the information handling system and determines an optimum MCC value that the battery cell can provide to the information handling system. The battery management unit further provides a first value on the PP indication, the first value being greater than the optimum MCC value, sums the amount of current provided to the information handling system that is in excess of the optimum MCC value, determines that the sum is greater than a threshold, and provides a second value on the PP indication, the second value being less than the optimum MCC value.
