Reading the documentation for an Odyssey battery that is in my van, I
noticed that it wants to be charged at 13.6 or 13.7 volts.

So I was going to set the voltage regulator pot (from the volvo dude)
to 13.6 volts at the alternator.

But I noticed that on 12 volts with this setting the refrigerator
gets SUPER cold in one of my syncro campers (a 91).  It is MUCH
colder on 12 volts than 110 volts with the is setup.

Then I wondered if such a high voltage would actually hurt anything
in the van.

I noticed that the fresh air fans sound cooked on the highest
setting, for example, but maybe they are bad already and simply need
to be replaced.

I don't mind replacing bulbs more often if that is the worst outcome.

If 13.6 volts is too high, what is a better choice for setting the
voltage higher?

Setting the higher charge voltage at the alternator maximizes the
lifespan of the Odyssey batteries so it is possible for me to turn
the voltage down and change them more often.
