Daily driver to back-burner -- Dead batteries now
I've driven my 2000 Platinum Series daily for years with minimal issues. Never had a battery issue until I got a company truck and stopped driving it everyday. Chewed through two cheap batteries in less than a month, so I "upgraded" to a better battery and that battery was dead in a few weeks. What are the most common issues causing a slow drain? I don't have anything aftermarket in the car. Any help is greatly appreciated.
Edit: Car jumps and drives fine, btw.

Most common reason for that IME is a bad voltage regulator inside the alternator. Charges poorly as well as a parasitic draw - double whammy. This is assuming your grounds and connections are all clear and good, which can also cause this.
With the car running, check for charging voltage at idle and at ~2k or higher, and also look for AC voltage across the battery terminal (leaking from alternator). Driving daily will mask the problem, sitting idle will expose it quickly.
