the battery can be disconnected if you let it sit for more than a week. most common drain that i encounter is in the audio system. disconnect the negative battery cable and put a test light (wired light bulb) between battery post and cable end. if the light is on or even dim, start pulling fuses one at a time. if the light stays on, replace the fuse and move on. if the light goes out then you have found which circuit the draw is in.
