A method for preserving battery operation and life during vehicle post idle shutdown, such vehicle having a delayed accessory power mode operative when an ignition state of the vehicle is in a non-engine running condition while an ignition switch of the vehicle is in the ON position to supply accessories in the vehicle the battery. The method includes: detecting whether the vehicle has been in an post idle shutdown condition and brake pedal not pressed and ignition state unchanged; and placing the vehicle in the delayed accessory power mode after detecting that the vehicle has been in an post idle shutdown condition and while the ignition switch is in the ON position.
