What about the newer dual purpose ( start - deep )
batteries?

Can't help but thinking this is a marketing ploy, everyone seems to be
selling them. I can't really understand what they mean by dual purpose,
unless they're implying that the one battery is adequate for both a house
battery application AND a starting battery, no need for another dedicated
"house" battery. Any deep cycle battery with the correct MCA rating for a
particular application will do as a starting battery, and having dedicated
batteries for house and starting applications minimizes the possibility of
not having enough juice to start the diesel, should also prolong the life of
the batteries.
