For the last month the alternator reads 14.9 to 15.2 volts in normal driving, whereas before the highest reading was 14.5 volts.  The battery is two months old,, a 120 ampH AGM battery that reads 14.5 volts. I have been told that AGM batteries should not be sibjected to more than 14.5 vots. My Porsche dealer shrgged it off and said don't worry, the alternator will cut out when the battery is fully chatged but the alternator keeps reading well over the 14.5 margin. Should I worry?

 

Thank you for any helpful advice.
