I upgraded my ole Southwind to a three stage converter last year, so I now leave it plugged into shore power year round. The converter automatically switches modes and when the batteries are charged, it switches into trickle charge mode (13.2 volts) that doesn't boil the batteries.

Before that, I had a single stage converter that put out 13.6 volt only. During long periods of storage, I'd disconnect the batteries using the "STORE / USE" switch.

I remove my batteries and bring them home to store in my garage. The building I store my MH in is not heated and the owner will not allow anyone to plug anything in for safety reasons.
I keep the batteries charged by hooking them up to a trickle charger monthly.
I have a diagram I drew on the rear of my battery compartment and the cables have red tape on the positive cable ends and black tape on the negative ends.
The diagram I drew has red and black Magic Marker circles around where the cable ends connect to the batteries. I also use + and - signs also drawn in red and black.

If you store outside the sun will do it for free. Mine has a 10 watt solar panel that keeps them topped off. I will be adding even more solar soon but just that small panel has paid for itself in saved batteries.

Why is no one using a battery tender? A good one will cycle change and dis charge. Been using them for years for boat and rv

What's the difference between a tender and a charger?

Thanks for all the great ideas here.!

A trickle charger continuously emits a small current of electricity regardless of the charge level or even if it’s full. This can damage your batteries over time. A battery tender will only turn on and charge your battery when the battery has self-discharged below a certain level.

Not this one. Does the same as a trickle charger in float mode.

A constant float voltage is the standard for maintaining batteries, not cycling them over and over.

Right from a Battery Tender instruction book.Click image for larger version

Our motorhome sits stored behind the house much more than it is used so this has worked out really well. The house batteries are a few years old and the chassis battery is from 2013. All are in great shape!



Disconnecting the batteries completely works ok too but it was more of a pain.
Be careful with a setup like this. With some chargers, they run through all charge stages each time they are powered up. By using only for less than a day, it may never reach the float level and end up charging at too high a voltage.

Here in Wisconsin, my batteries are connected to the multi stage all winter. I check water levels about once a month (on the occasional nicer day), and I peak in the window daily, if possible, to glance at the voltage gauges to confirm things are doing well.

I do a more thorough check every couple of weeks, since I have to check the sticky traps for mice.

Batteries in the winter

I agree with Keymastr, Solar charger is the way to keep batteries charged all winter. Go green, free power.
I have a solar panel on the roof of my RV with a 4 pack of 6 volt batteries. 2 winters with no issues.

My solution has been solar for the winter same as many other responses. Only thing I would add to that is make sure there is little to no parasitic drain if you are in an area like I’m in. With flat panels, clouds, temperature inversions and several inches of snow on the panels, even a fairly large system doesn’t deliver more than a trickle.

Great idea but I use an RV cover, so as much as solar is a good idea, won't work under a cover. Hmmm, unless I temp up a portable solar system. Anyone have this on 4 6V's?
