I don't see anywhere where Trojan defines their Marine / RV batteries as being any less "deep cycle" than any other of their deep cycle products, be it the AC Series, Plus Series, etc. In fact, the popular Trojan T-105 GC-2 battery is part of this Marine / RV series which offers choices in both 6 volt and 12 volt configurations, with neither being any less "deep cycle" than the other. You are never going to SEE this..."Our RV batteries are not quite as cyclable as our golf car or industrial units...however"
Knowledge comes from asking questions and not making assumptions.
DEEP CYCLE is one of the most abused, misunderstood and erroneous BUZZWORDS in the marketplace.
Fistfights broke out over this in Chicago. People who were informed Dewey lost started throwing punches "cause they read it somewhere that he won, or were told so by their best friend"
