Abstract: In one or more embodiments, one or more systems, methods, and/or processes may determine that a timeout value has been reached; for each battery cell of multiple of battery cells: may determine if a temperature value associated with the battery cell meets or exceeds a threshold temperature value; if the temperature value associated with the battery cell does not meet or exceed the threshold temperature value, may permit the battery cell to be charged and discharged; if the temperature value associated with the battery cell meets or exceeds the threshold temperature value: may increment a temporary fail count associated with the battery cell; and may prevent at least one of charging and discharging the battery cell; may determine if temporary fail count exceeds a temporary fail count threshold; and if the temporary fail count does not exceed the temporary fail count threshold, may permit charging and discharging the battery cell.

Abstract: An information handling system real time clock (RTC)/CMOS circuit is powered from a battery that powers the information handling system. The battery power is supplied through a power management circuit that manages power constraints to the real time clock and that protects the battery from exceeding current and voltage thresholds. A protection integrated circuit selectively cuts off power supply from a power module to the RTC/CMOS circuit if predetermined conditions are detected. The protection circuit may also cutoff all power from battery with a permanent failure option or may itself directly supply power to the real time clock/CMOS circuit.
