Abstract

A battery charger for use on lead acid and dry cell batteries having a polarity detection mechanism, automated current routing circuitry and connected adaptive illumination. The battery charger of the present invention includes an internal battery, an external battery, a solenoid-type switching device and a control circuit. When connected and activated, input from the battery to be jump-started is routed through a control circuit so as to function in conjunction with the internal battery to activate one of a pair of solenoids so as to provide a proper pathway that ensures the configured to provide safe, spark free jump-starting, as well as convenient illumination to the user.

Claims

1. An automobile jump-starter configured to properly connect an internal battery having a positive terminal and a negative terminal located with an external battery having a positive terminal and a negative terminal said automobile jump starter comprising:
