1. A battery system for an information handling system, the battery system comprising:
a first battery;
a second battery;
a controller; and
a memory medium communicatively coupled to the controller, the memory medium storing a primary battery indicator designating the first battery as the primary battery and a set of instructions executable by the controller to:
determine an operating temperature of the first battery;
if the operating temperature of the first battery is equal to or greater than a reliability temperature threshold:
determine an operating temperature of the second battery; and
if the operating temperature of the second battery is less than the reliability temperature threshold, switch the primary battery indicator in the memory medium to designate the second battery as the primary battery; and
if the operating temperature of the first battery and the operating temperature of the second battery are equal to or greater than the reliability temperature threshold, the set of instructions are further executable by the controller to:
determine if the operating temperature of the first battery is equal to or greater than a pre-shutdown temperature; and
if the operating temperature of the first battery is equal to or greater than the pre-shutdown temperature and the operating temperature of the second battery is less than the pre-shutdown temperature:
switch the primary battery indicator in the memory medium to designate the second battery as the primary battery.
