Abstract
A power supply back-up device is capable of supplying auxiliary electrical power to a motor vehicle when the vehicle storage battery is disconnected. The computer memory back-up device comprises a plug for inserting into the vehicle cigar lighter, a body with contacts for engaging a nine-volt battery, and wires joining the plug and body. Voltage from the nine-volt battery energizes the motor vehicle circuit when the main battery is disconnected for service, thereby enabling computer controlled accessories to retain their pre-set settings. As a result, reprogramming the accessories after removal and restoration of the normal and electrical power is eliminated.
