Reasons why my car won't start (aside from battery or alternator)?

What is your question?

Car is up to date with maintenance. The battery was being drained while the car remained parked/off. We would start it weekly, then sooner after we saw the car needed a jump more often. Now no kind of charge is delivered even with jumper cables. Battery is brand new. No other lights or gauges turn on when key is in ignition. Ideas what else it could be? Battery cables look good. Car is at shop now getting formal diagnoses. Just want to see opinions.
