A fully charged 12 volt battery is
12.6 volts.

13.2

2.2 volts X 6 cells equals 13.2

Nonsense. You obviously have never actually used a voltmeter on a boat. The
"open circuit voltage" varies a bit with the technology, but will generally be
between 12.6 and 12.8. It may read a tad higher after charging, but settles in
a few hours.
