How long does your Optima battery last?

What are the details of your charging system, IE one wire? Mopar "dual field?"

14.6 is too high, but also, you need to measure it with engine / regulator warmed up. The regulator is temperature compensated.
The charging system is stock mopar, dual field alt, I will measure it at temp this weekend. I went over all connections and measured voltage at all points, batt, alt, solenoid and starter. saw no voltage drop. the car seems to charge fine, maybe battery just going.
