Henry, I have the desulfating battery minder plugged in 24/7 when not camping and the camper is outside. I have a box setup to keep the weather out of it. Then when we are ready to head out on a winter campout we are good to go.
Your PD converter will drop into float mode and desulfate every so many hours. Your good to go.
Some day when you get to the batteries.... get a pigtail to go on the battery terminals and let it hang outside. Then plug your C tek unit in that is inside a plastic container. I'll have to take a few pics of mine. This gives you the option to not have to run the PD all the time and get the benefit of the C teck pulse desulfater and save a little electric in the process. The PD which is still great does not use the pulse method for desulfating it uses the older raise the voltage for a time period method.
