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.
Reasons why my car won't start (aside from battery or alternator)? on 1994 Chevrolet Cavalier
Chances are, the repeated draining of the battery has killed it. Even though you claim its 'new', its been in there long enough (or several seasons) that this long cycle of drain/recharge has damaged the battery.
