Bad Battery?

On shorepower with charger connected/running:

14.x volts at isolator (port/starboard/house)
14.x volts at port start battery
14.x volts at house batteries
12.2 volts at starboard start battery

All batteries are AGM about 2 years old.

I should have pulled the cable off the starboard battery but didn't think to do so until I had left.

Bad cell in the starboard start battery? Or...?

    Of course, all grounds are good and charger has stages for AGMs. No AGM should fail in two years from normal use unless it was defective. If so you should be able to return it.

    Maybe the isolator and charger wasn't sensing the starboard needing charge at that moment?

    @Aqua_Aura there was 14.x volts at the charger output for all 3 batteries.
