1. A battery discharge protection system comprising:

  • a) a microprocessor being capable of receiving a plurality of inputs, said inputs corresponding to signals from a vehicle;

    b) a plurality of electronic switches being configured for movement between an open current position and a closed current position, said closed current position connecting an electrical load to said battery, said open current position disconnecting said electrical load from said battery;

    c) a gate input circuit for manipulating said switches between said open current position and said closed current position in response to an output received from said microprocessor; and

    d) a bypass circuit allowing a minimal electrical current for maintaining volatile memories of an electrical component to bypass said plurality of electronic switches.
