I would disconnect the batteries and take them to my house.
I can set them on a shelf and put a trickle charge on them sometimes.
Less chance of them walking off that way.
ALSO...
Make sure every door and Hatch is locked. Don't leave anything in you storage unit or camper that might be stolen.
Wouldn't hurt to put a shackle on your trailers hitch too.

Related to my TT battery’s winterization, am I good just plugging in the TT? Will this keep the battery warm/charged?

Most campers have WFCO converters that are supposed to automatically switch to "float mode" to keep a battery topped off. Unfortunately most WFCO converters operate only in adsorption mode and NEVER switch to float mode. If your converter operates this way it could overcharge your battery if left connected for a long period. This may cause the water level to drop and damage the battery. I believe you would be better off using a dedicated float charger.

Hi profdant139,

1% per day for an old tired worn out jar.
6% per month for a brand spanking new battery.

The colder it is the slower the chemical reaction--so cold storage is better so long as the battery is fully charged to start with.

That said, I will leave my car on a 1 amp charger for 3 hours per day for the next 120 days. But that is because of parasitic loads from the vehicle.

So I am going to display my ignorance, once again -- I had thought that if a battery is left disconnected, it will discharge about one percent per day. And after a couple of months, that discharge could shorten the battery's useful life.

I'm in Ontario where it gets cold. For the last 40 years I fully charge the 2 batteries in our boat and ensure no loads on them. For my Miata and John Deere tractor the same thing - fully charge and take off battery cables.

I leave them in Nov and come back in April. Batteries are all still mostly fully charged.

Batteries with no load on them are fine in cold weather over the whole winter

I used to do this and found that it shot my energy bill up substantially. Didn't realize what caused it til I sold that trailer and it left. Then my Electric bill went from $120.00 to $60.00-$80.00. That was running a converter.

Instead of powering up the converter and any parasitic loads, I disconnect the battery and use a Battery Tender for a few days a month. It could be left on indefinitely, but I have other uses for it. With the trailer plugged in it is exposed to any electrical glitches in the power system. Cold will not harm a fully charged battery, in fact cooler temperatures are better for it.


My Brother does a similar set up as you do but he set up a timer so it cycles on and off a couple times a month.

True That.

It is amazing to me that the most common convertor on the market is the worst one.

My WFCO wasn't awesome by any means, but aside from no real boost mode, it charged and maintained the batteries OK.

I used to mess with removing the batteries, but that is a pain, literally. Mine sit on the tongue of the trailer that's plugged into shore power. I haven't noticed that huge electric bill noted above.

Least amount of effort, most bang for the buck.

The WFCO converter has worked for us, too. I want to change it out for a Progressive unit, though.
I haven’t seen a jump in electric use, either.
