Talking Batteries in "storage"

Same for us. Although for just one winter so far!!

Our AS has a battery cutoff switch inside a front interior compartment. I turn it off when storing and wire a battery maintainer to the battery which I plug into a timer that comes on for thirty minutes a day. The stock system is supposed to not over charge but I lost three batteries in about five years.

Good idea to unhook the batteries and take them inside in the winter if you live in a cold climate -- and hook them up to a battery tender as others have suggested.

Totally unnecessary to do anything but to charge them up then unhook them. See my post and test on 5 months of battery storage at 0 to 5 degrees F.

People in Alaska, northern Canada, North Dakota leave tractors and trucks sitting all winter long in sub zero weather without doing much other than as Idroba says. The liquid in a charged battery is not the same thing as water.

Batteries self-discharge without anything hooked up to them, but if they have not been repeatedly discharged below a level of charge ( which varies with battery type) they should charge back up again without any problems.

If using a trickle charger, the best ones are like the MPPTs we use on boats. They allow you to adjust the float rate. A float rate of 13.8 volts I think, for lead acid batteries, will vaporize some electrolyte after a while. This means that the acid level in the batteries will drop down toward the plates if you don't top them up.
If you can adjust the float of your charger to 13.2 volts for the winter, the batteries don't gas during charging.

Great info! I was mis-informed about the effects of cold temps on the battery -- thanks for the real-world testing. I'm delighted that we can now forgo the annual ritual of dragging the batteries inside!

I have the stock converter and original batteries in my 2010. I leave it plugged in when parked, although care is required to be sure the water heater and electric heat are off.

The stock converter is not temperature compensated and will tend to overcharge batteries in hot weather. I check them every few weeks and add distilled water if needed, usually just once a year.

In cold weather, the stock converter won't fully charge the batteries, but it will keep them charged enough that they won't freeze.

How is leaving the AS plugged in for storage any different than leaving plugged in for 3 months when are living in it in Florida?

Re freezing of batteries

If your battery is really discharged, then the specific gravity of the battery acid is low enough that it will freeze at somewhere below 0 F. Fully charged battery will withstand -40 easily. So if you live in a really cold winter area you just need to be sure the batteries will hold their charge in storage.

Now I have installed a solar that takes care of it at no cost through the converter.
No more unhooking and re-hooking up!
Also when I travel and boondock I don't have to use my generator.
May I ask about your solar installation details, I'd like to do more boon docking but I don't have a generator yet, thanks
