I purchased my DMax in the summer. Now that winter is here, I was wondering about how the two batteries work? Are they simply interconnected or is one used for certain loads and the other for other functions? If I want to park the truck for several weeks, do I need 2 float chargers?
I guess I should pick up a "Haynes" for the electrical diagrams...
I would get out of the truck, close the door and not worry the batteries for even a month of sitting.
My spare 04 1500 (Old and Busted) sits for months at a time with an Interstate blem battery in it. Usually starts no problem. My 48 hp John Deere sits outside for months in the winter without running and starts fine.
If you ever change batteries you have to, change both at same time. Your system is only as good as your weakest battery same goes for TV remote cant have 2 new ones and 1 bad one
