[C38] Battery Voltage

[Robert Miller]

I have 4 AGMs.  I isolate one for a start battery and thus have three 12V
AGMs for the house bank.  When fully charged they all show 13.5 on my
chartplotter.

I've been doing some research and cant find what Im looking for, so Ill
throw it out to the group.  for my start battery I have a 12v lead/acid, for
the house bank two 6 volts in series.  Nice new voltage meter installed in
the panel so I can see the state of charge.  Charged them up last night and
today,  The start battery settled in three hours later at 12.6 and the house
bank 12.9.  I have found info  all over the net stating fully charged
batteries should be 12.7, 13.1 or 13.5 first question is which should it be?
Second is why do I get a .1 difference when looking at the panel read out
versus a multimeter on the terminals......the multimeter reads lower.   As
always thanks.
