Engine idle, battery voltage reads 14.4V
Engine off, lights on for 1 minute, voltage reads 12.03V
So it seems it's borderline case for battery replacement. Is that your assessment too? What would you do?
I would not change the battery and alternator (yet). The whine could be something else. Maybe an idler pulley or tensioner (or just radio interference). If you are not having any drivability issues, save your money for later. A month ago, I tested my battery (5.5 years 38k miles) and alternator (6.5 years 48K miles). 12.00V and 14.48V respectively. I decided not to mess with it.
