    I have ordered two Trojan T105 batteries for my new Sunline travel trailer. They will be hooked in serial. I am assuming that I can charge the dual 6 volt T105s with an external 12 volt, 3-phase deep cycle charger. Do I treat the two batteries as one 12 volt, keeping them hooked together while charging?

    Charging Dual 6 Volt Batteries

    yes, 2 6 volt batteries with a heavy cable from the positive connection of one to the negative connection of the other (serial hookup) is electrically indistiguishable from a 12 volt battery. The only time you might have problems is if one battery has a problem and the other does not.
