SOURCE: Battery dies while sitting idle
Well it could be possible that you have a cell that is going bad.. This would cause battery to fade with little draw from onboard accessories (ie: clock, etc...) Why not spend a couple dollars and install battery isolation switch you can flip when vehicle is expected to sit for a duration... I know this doesnt solve the drain problem you have but could be a solution for not having to jumpstart it when you need to ude it..Good Luck

Have you checked the alternator? The alternator may not be charging the battery. With engine running, check the voltage at the battery (it should be ~14V). If it's less than that, your battery won't charge properly. You can take your alternator to auto store to have it load tested also to be sure. Sometime alternator issues don't show up until it gets hot. Defective alternators have also been known to drain the battery after the car has stopped.

There is an alternator fuse located on the positive battery clamp or in the fuse block under the hood. if it is part of the positive battery clamp it is a dealer only part and will run $10 to 20 dollars. If it is in the fuse block you should be able to get one at the auto store and modify it to slide in easily. Get a flash light and check all of your fuses carefully. The blown fuse may be hard to spot. The design of the car lets the battery go dead with out even turning on the charge light on the dash to let you know you are not charging the battery.
