A healthy battery should last a few weeks of idle time before the clock affects cranking power. - Dave
Thanks Dave. Very interesting, and I would assume a constant draw when changed to a quartz replica clock?
That antique car "click" is funny because the 2013 Charger RT lit up the instrument panel with lights and operated the wipers one swipe when the battery became drained. Even the power windows and lights worked, but not the power seats. The Check Engine light remains on because a couple throttle sensor codes are set when there isn't sufficient battery power. Lucky I have an OBDII tester that will clear this once the battery is re-charged.
As I said, we lock the car now so it will enter "sleep mode".
