As said above, if the battery is original, it's probably time for a new one. If it's a new battery, then you'll need to do some elimination to find out what's drawing so much current. Get an ammeter and put it inline with the positive lead....in between the battery and the load. Set it to read the amp draw and them start systematically unplugging fuses to see what drops the current flow significantly. It might take you a little time, but it will be well worth the effort to find a faulty component if you have one.
