System and method for dynamic switching between batteries in a dual battery system

A dual battery system for an information handling system, the dual battery system comprising:

• a first battery having a first battery management unit (BMU);
• a second battery having a second BMU;
• a controller communicatively coupled to the first BMU and the second BMU;
• and
• a memory medium communicatively coupled to the controller, the memory medium storing a primary battery indicator designating the first battery as a primary battery and set of instructions executable by the controller to:
• read a wear level of the first battery;
• read a wear level of the second battery;
• determine a difference between the wear level of the first battery and the wear level of the second battery;
• and
• switch the primary battery indicator to designate the second battery as the primary battery if the difference between the wear level of the first battery and the wear level of the second battery is equal to or greater than a wear level difference threshold.

A portable information handling system contained in a chassis, the information capable of drawing power from a dual battery system comprising:

• a first battery having a first battery management unit (BMU);
• a second battery having a second BMU;
• a controller communicatively coupled to the first BMU and the second BMU;
• and
• a memory medium communicatively coupled to the controller, the memory medium storing a primary battery indicator designating the first battery as a primary battery and set of instructions executable by the controller to:
• determine an operating temperature of the primary battery;
• if the operating temperature of the primary battery is equal to or greater than the reliability temperature threshold:
• determine an operating temperature of the secondary battery;
• and
• if the operating temperature of the secondary battery is less than the reliability temperature threshold, switch the primary battery indicator to designate the secondary battery as the primary battery;
• and
• wherein the set of instructions are further executable by the controller to:
• read a wear level of the first battery;
• read a wear level of the second battery;
• determine a difference between the wear level of the first battery and the wear level of the second battery;
• and
• if the difference between the wear level of the first battery and the wear level of the second battery is equal to or greater than a wear level difference threshold, switch the primary battery indicator in the memory medium to designate the second battery as the primary battery.
