First boat so dumb question: I have a new 2006 Triton TR196 and it has a Duel Pro Charger. It has the two batteries(i'm assuming TM batteries) on one side and another battery(assuming the cranking) on the other side. Is the cranking battery hooked up to the Duel Pro Charger at all or am i just charging the TM batteries when i plug the Duel Pro in? Do I need to charge the cranking battery separately from a portable charger and is so how often?
