A battery voltage boosting system comprising:

• a switch configured to connect a voltage boosting circuit to a battery;
• said voltage boosting circuit comprising:
• a collector of a PNP transistor coupled to a base of an NPN transistor;
• a collector of said NPN transistor coupled to the battery through an inductor when said switch is positioned to connect said voltage boosting circuit to the battery;
• and
• a collector of said NPN transistor coupled to an emitter of said PNP transistor through a resistor and through said inductor.

A battery voltage boosting system comprising:

• a switch configured to connect a voltage boosting circuit to a battery;
• said voltage boosting circuit disposed in a disc-shaped housing;
• and
• said voltage boosting circuit comprising a conductive tab extending from an outer circumference of said disc-shaped housing, said conductive tab comprising a terminal connector of said voltage boosting circuit.

A method for boosting a battery voltage comprising:

• sensing an output voltage of a battery;
• activating a switch if the output voltage of the battery falls below a predetermined amount;
• boosting voltage by passing current through an inductor and through a collector and an emitter of a first NPN transistor when the switch is activated;
• and
• controlling the NPN transistor by adjusting a voltage applied to a base of the NPN transistor from a collector of a PNP transistor.

A battery voltage boosting system comprising:

• a housing;
• positive and negative input terminals;
• positive and negative output terminals;
• said positive and negative input terminals projecting from a first side of said housing;
• said positive and negative output terminals projecting from a second side of said housing;
• said first side of said housing and said second side of said housing comprising opposite sides of said housing;
• and
• a battery voltage boosting circuit disposed within said housing and communicably coupled to said positive and negative input terminals and said positive and negative output terminals;
• said positive and negative input terminals positioned such that when attached to positive and negative battery terminals of a depleted combustion engine vehicle battery said battery voltage boosting circuit boosts voltage of the combustion engine vehicle battery to a level sufficient to cause the combustion engine vehicle to be started.

A method for starting a combustion engine vehicle with a depleted battery comprising:

• connecting positive and negative input terminals of a voltage boosting circuit to respective positive and negative terminals of the depleted battery;
