The Izze air pump delete module draws a mere 0.5 mA of current, so that can be ruled out.
With the car off, I would suggest using a multimeter and measuring the current draw through the negative battery terminal. The pc680 is rated at a capacity of 17 Ah and an OEM size battery is ~35 Ah.

I've had very poor experiences with "lightweight" batteries in the S2000, particularly the longevity. From what I understand, dry cells are very sensitive to how their charged; slightly overcharging them can significantly deteriorate the batteries life cycle.

from what i read those dry cell batteries are not good at all and will even die if the radio is left on for 15 minutes. They require long trips to recharge and are not recommended for city/in town driving.
I would buy a real battery and see if the problem persists. I doubt it will.
I have had a pc680 battery for over a year with no issues until recently.

thank to Dwight for the wikihow, i'll do that and try to see where my draw is coming form

My PC680 used to last only like a week or so with aftermarket alarm... i took the alarm out (for another reason) and now it can do few weeks of no dirivng without problem.
