Winter storage for deep cycle batteries?

Howdy,
My new 2014 Mini-Lite is now winterized and parked out back for its first winter. Mid-winter temperatures here in eastern Oregon at 3K feet + will dip below 0 degrees F from time to time. Should I disconnect and remove the two batteries and bring them into a heated space, and/or set up a trickle charger from time to time?
Any advice would be welcome. Thanks. Max

Mine survived sitting out last winter, but not without a lot a fretting. (See here: Is DW right? Was it bad to leave the battery in the trailer over winter?)

Generally though, the answer is yes, they should come in, and yes, they should be charged periodically to keep the voltage from dropping too low.

I would vote do what you can. Get a trickle/battery maintainer for the winter. I have a 2011.

I've come to the conclusion if you don't maintain your battery (as in keep it in shape all year long) expect 3 years out of it. And they tend to go fast without much warning. I went dry camping last weekend, previously my battery meter goes from 10 bars, to 9 bars, etc. as the battery gets used. I setup this time and see 10 bars then as soon as I turn on a light 4 bars!!! I was on critical power saving mode that camping trip (the fridge even though it runs on propane needs electricity to run its circuitry). I get home, plug it in and recharge, and the battery now can't hold for an hour. Now I'm in the process of pricing new batteries, researching what I should've done, looking at battery keepers, etc. and so far come to the conclusion it's cheaper to maintain the batteries than replace them every 3 years. The sooner you start the more you'll save.

Do you leave your unit plugged in all winter? There are ways to get around to not having to remove them. I did some research on mine, because I didn't want to remove them(bad on the back).

I would disconnect them to remove parasitic loses. Then hook up a Battery Tender or Battery Minder to maintain them.

I used to take the dual deep-cycles out of my old TT, put them in the unheated garage on an automatic charger/maintainer. They were also in a box made of 1" foamboard so their own heat may have kept them slightly warmed. Still had the same capacity at 9 as they did when they were brand new.

With the 5er, I'm just going to leave the shore-power plugged in and let the converter float the battery.

If you have a WACO converter it will stay in 13.6 volts unless by the manual it has to read no loads for 48 hrs then it will drop to 13.2, it can't happen because it read parasites as people said. IF your going to use your 3 stage converter/charger, there is cheap add on it's called power plus. What is does is hook's to the pos and neg. and will keep your plates clean. That is what will kill a battery, or go to a progressive converter that has 4 stages. The 4 stage will come on every 21 hrs and bring your voltage up to 14.3 to burn it off. The power plus is about 35.00 the progressive is about 145.00 but it will drop to float at 13.2 not like the WACO. I forgot it might be a WFCO/ not WACO. either way it is the standard one FR puts in, except in the Sunseeker. I was told they were going to switch and were testing them out.

So who makes this device called a "Power Plus"? And where can you buy one?

I did a quick google search and didn't find anything specific.

I'll try and find it again and get back to you, you will still need to keep a close eye on your water level. At 13.6 you will gas quite a bit... Type in Power plus battery maintenance system it will come up on google.

OK it found the following for a company called "PowerPulse" providing a device that "removes sulfation buildup on battery plates".

Is this it?
