Starting a Car on a Dead Battery?

Is there a way of disconnecting all electronics of the car so that the battery will start the car without going flat. Because I charged the car battery, I think, well it was on charge for hours and hours, and when I put it in car nothing happened I just thought something was draining it. Surprisingly jump cables didn't work either, the dials light up but car didn't start. Is there anything else I can try, But I don't want anything too expensive because its just an old car lying in the street, I was planning on getting started and rallying about in. :)
