section 22 in parallel e deep discharging v a u2266 10 8v for an extended period of time with or without vibration present the present invention operates in the following manner as a starting condition the battery is in state a both the sta section 20 and the aux section 22 of the battery are fully charged normal state and the l r is in an open state in this state only the aux section 22 is connected to a vehicle wiring system coupled to the battery via the external terminals 10 44 the vehicle includes a vibration sensor not shown connected to the u03bcp 34 the vibration sensor may be a piezo electric vibration detector circuit for example when the vehicle is entered the vibration associated with opening the door or other disturbances will be detected by the vibration sensor in turn the u03bcp 34 sets a 34 vibration detected 34 flag dvib to true the u03bcp 34 checks v a since the u03bcp 34 will find v a gt 10 8v the present battery configuration will be maintained i e only the aux section connected to a starter motor a key is set to a start position engaging a starter solenoid to turn the starter motor the high current drawn by the starter motor will cause the aux section voltage v a to decrease.
