    I supposed to draw a constant current from a lead acid 12v car battery.
    i need a help to implement a circuit for that.

    may be this one help you rather than your circuit.
    in your circuit load is the transistor.
    so when it is biased definitely it will go into saturation region,

    that circuit of yours isn't going to work, its just going to short circuit the 12V battery and the transistor
    when current is applied to the base of the transistor to put it into conduction
