I have a 2015 Heartland Landmark 365, that came with 2 batteries. My question is, does Heartland ship their units with batteries or are they supplied and installed by the dealer? I am trying to figure out if they are AGM or Standard batteries. I don't exactly want to disconnect the hood and remove the batteries from the battery well just to find out. Since it is a 365 with a power inverter to run the refrigerator (115 Volt Only). My thinking they would be AGM due to the longer life. I am just not sure. The 5th wheel sat at the dealership for over a month without being plugged in for any time, thus draining the batteries. I am trying to charge them but don't know if I should set the charger for AGM or standard. I have been trying standard just in case.
