Answers:
You have whats called a parasitic drain. Somthing is staying on or allowing current flow, slowly draining the battery. Usually a light (glove box) is staying on or one of the modules may have an internal short. You need to measure the amp draw of the electrical system (.025 - .035) is the norm. Anything above that is excessive. You pinpoint the circuit by removing fuses, one at a time, untill the draw goes away, then disconnect components on that circuit till the draw goes away.. Could be any number of things, including the vanity mirror light staying on..
you need a new battery mate,
Something with the security alarm was draining mine for a while - not sure how they fixed it. I hated my Jeep. It was a piece of **** and I think it was cursed. Now, I know the person who has it (my mother-in-law) and it works just fine for her! I had SOOO many electrical problems with it.sell it while you can! Mine was a '96 Jeep Grand Cherokee Laredo - not sure if yours is the same model.
I've had this problem before. It can be a ***** to troubleshoot. Depending on your level of competency, you could find it by process of elimination. I would start by suspecting the alternator. Always disconnect the negative on the battery first before attempting to troubleshoot. Then disconnect the main power lead to the alternator (usually a fat red wire). Then lightly touch the negative terminal to the battery and see if it sparks. If it does, the drain is somewhere else and you'll have to start pulling fuses one at a time until the spark goes away. If it doesn't spark, you have a classic case of leaky diodes in the alternator. Hopefully, that's it, because the alternative could be grueling to say the least.

I hope this helps.
Unplug your glove box light. That'll solve it. I had the exact same thing on my 94 Cherokee. It had sat for awhile I took it to a shop for some work they replaced the battery and the next morning it was dead again. Then they found the glove box wasn't shutting off it's light so it's unplugged and all is well going on two years now.
alternator is likely shot - most "battery" stores can test for free.
I have a 1996 MGF with the same problem.
If the glove box light isn't your problem, check out your alarm/immobiliser which is a constant drain on the battery even when its not on. You may be able to isolate it in the fuse box.
now if your driging it around those 2 days and it loses its charge its because your alternator is bad and its not charging your battery. but if you are not driving it and it loses its charge then make sure you dont have anything like a light or something thats going to pull your power but im assuming thats not the case if its your primary vehicle its most likely going to be your alternator.
