if the battery is new and the alternator has been changed there must be some form of parasitic draw on the battery. Some electrical load is staying on after the keys have been taken out of the ignition switch. could the interior light or trunk light be staying on?
To find out if there is something staying on that would be running down the battery the battery is disconnected and an amp meter is put in the circuit to see if the battery has a draw. Disconnecting the fuses one at a time while watching the amp meter would determine which circuit is causing the electrical draw.
