From reading other owners threads with alternator problems go with an AC Delco unit, after market alternators seem to give these cars a tummy ache

I just replaced my battery and alternator. I put a 120 amp in it and a higher CCA battery also. Battery saver mode can mean the battery is going.

Is the light still on? If so the alternator is bad. I got an AC Delco from rockauto.

What brand of battery was installed a few months ago? Besides the Florida heat, any other reason(s) necessitate using a heavy duty alternator on a G8 V6?

Numerous bad experiences with Duralast batteries and best of luck in the hunt for a heavy duty alternator.
