Claim Text:
1. A discharge circuit for discharging a vehicle battery, said battery including a positive terminal and a negative terminal, said circuit comprising: a reference voltage source separate from the battery and providing a reference voltage, said voltage source including a negative terminal and a positive terminal, said voltage source being electrically coupled in series with the battery where the negative terminal of the voltage source is electrically coupled to the negative terminal of the battery, where the voltage source is a variable voltage source so that the reference voltage can be changed; and a load electrically coupled in series with the battery and the voltage source, wherein a current flow through the load generated by the battery discharges the battery to the reference voltage, wherein the voltage source and the load are part of a portable unit that can be selectively electrically coupled to the battery.
