Pull the negative cable and go.Tenders are fine, but I found just disconnecting the batteries and leave them alone worked for me. When I came back from Florida to Wisconsin after 4-5 months everything started right up. It maybe didn't crank like a new car, but it only needed to start.
I used to pull my 3 boat batteries and then got smart and just shut off the master switches and that was the end of that needless extra work.
