A battery jumper cable assembly for automatically assuring the safe connection of two storage batteries in a parallel relationship for charging the batteries or starting a motor vehicle which has a dead battery. Four normally open solenoid switches are included in the circuitry to align the two batteries automatically in proper polarity regardless of how the terminals of the two storage batteries are actually connected. An indicator light glows continuously when the hookup is completed and operating.
