Might have a switch bad, or something wired wrong that's draining the battery constantly.

Take a voltmeter to your fuses and see which one is pulling power. On my old CRX, I had the defrost switch go bad, and it never turned off.

one of the most simple ways to find a paracitic drain on the eletrical system is to get a test light and then disconnect the negitive cable on your battery, then connect one end of the test light to the lose battery cable then touch the other end of the test light to the terminal. if the test light lights up you have a drain, from there you systematicly pull each fuse indvidually untill the light goes out. that will tell you what component is bad or causing the drain. i would start with the fuses under the dash then move to under the hood. in my case it was my ac fan motor, but you must make sure that when you do this all doors are closed and the keys are out of the ignition. hope this helps.
