The resting voltage would drop over time but this doesn't matter if the alternator, (Engine ON), voltage remains constant.
It will be ~ 12.5 V when the motor is off, up to 14.5 V while just started, and once the battery is topped off by the alternator the voltage will drop to around 12.5 - 13.0 V for warm running.
Perhaps the belt is slipping past the alternator and the charging voltage is dropping.
Specifically, if I have a lot of OEM accessories in my 2008 Jetta 2.5 L SE, that are all turned on (e.g., heated seats, AC, defroster etc), or, if it's really hot and humid outside, and I have AC running at full speed, and the engine sensor is so hot that it turns on the engine cooling fans at full speed, too, and voltage immediately drops and stays below 13.2 V (e.g., below 2.2 V * 6), but is still above 12V, is there a problem with the alternator / voltage - regulator (mine's a combined part), or is that by design?
