the alternator could be doing it.
a friend of mine has a Saturn and he put in a new battery and then a couple days later had to replace the alternator being the new battery kept losing its charge.

If your alternator has a built in regulator (most vehicles do these days) it has a bad diode in it. A diode is like a one way valve for electricity. if it is bad, the diode in question allows current to flow backwards and actually drain the battery. Just replace the alternator.

Stick a light tester between the neg. terminal and cable. Then pull fuses one by one 'till the tester light goes off. Now you know the circuit so you can decide if that accessory is important enough to fix. Just be careful that you know everthing that's on that circuit. That's tricky; you never know what they were thinking.

oh, those dodgy dodges, they always have a power drain somewhere, good luck, they are hard to troubleshoot. It should start with a fresh charge though, you may have multiple problems.
