In one embodiment, a vehicle telematics device is disclosed with a hibernate control circuit. The hibernate control circuit can selective switch battery power on and off to hibernatable circuits. The hibernate control circuit can be responsive to external main power availability, battery charge condition, and a periodic low frequency clock in the generation of a battery switch enable signal. A power supply switch can be selectively controlled by the battery switch enable signal to switch battery power on and off to the hibernatable circuits.
