New alternator 15 volts 2002 Lesabre

[Rocky1]

2002 Lesabre, has new battery, all terminals are clean including the battery to Frame in both locations… My old factory alternator charged at 14.7 -14.8, installed a new Duralast alternator and it fluctuates between 14.8-15 volts, I did see 15.1 briefly on the digital display it mostly 14.9 to 15 volts . I checked at the battery with my DVOM and I’m reading 14.95 at idle with the heat on low to medium speed. Is this a normal range on these cars?

I just checked my 2003 Lesabre and it’s about the same 14.7-14.9

My '04 does the same...everything is OEM.

I appreciate you checking, for the heck if it I swapped the new alternator into my 2003 and it was roughly 14.8-15 volts so I’m assuming it’s ok, I normally just watch the temperature and seldom go to voltage on the digital display….
