Abstract
Systems and methods are provided for implementing a persistent battery system shutdown condition when a battery pack voltage level drops below a predetermined minimum acceptable operating voltage threshold that is above a pre-determined permanent failure operating voltage threshold at which the battery pack is permanently disabled. The disclosed systems and methods may be implemented such that shutdown portion of the power-consuming components of the information handling system are not allowed to be restarted until external power has been first provided and applied to at least partially recharge the battery cells of the battery pack to a battery voltage level that is above the minimum acceptable operating voltage threshold and/or when sufficient external power is applied to power the information handling system and at the same time charge the battery cells of the battery pack.
