House Batteries

I learned in March from the dealership where I store my 2011 Berkshire 390BH that my batteries froze even though they had started and run my RV in December. I live in Chicago and store my RV outdoors in Indiana where temperatures in January and February dipped down to -20 below zero. All four Crown batteries either burst or bulged. I had just installed these house batteries in July 2014. Is this typical? The dealership is telling me that it is although they sold me the batteries in the first place so I'm a bit skeptical. Can't get anyone from Crown Battery to return my phone calls. Thoughts? Advice? Anyone else experience this at all?

I was raised in Iowa where the temps can easily hit -30 at times. Our batts NEVER froze UNLESS they were not fully charged. Just my $02 worth.

Perhaps yours were dead, even though they said they started the coach at least once??

Boowho??

It does not matter how new your batteries are, it matters what the charge state is (the Specific Gravity). When buying new batteries, they are not new; they have been setting around for six months or more.

You need to have a full charge when storing and then disconnect them from the motorhome; either by the disconnect switch at the front door or better yet, by the manual disconnect switch in the battery compartment (if you have one).

It would be nice to have a trickle charge running while in storage, but if not possible, I would suggest you to periodically visit the storage facility in cold weather and run your generator for about and hour. to charge the batteries.

House Batteries

I have a 2014 390BH and had the same failure this winter. I am in ND and temps were -20 to -30 for a few periods this winter. It was a frustrating $550 lesson to learn. Just the house batteries failed. The engine batteries were fine. I properly filled fluids just before storage and fully charged, I set the internal disconnect switch to store and turned the disconnect at the battery to off. After discovering four burst batteries this spring, I got to the root cause. There is a connection to the inverter which causes a parasitic drag on the battery. It is not part of the disconnect - a less than ideal design - the mechanical disconnect should be a true and total disconnect. Under severe enough conditions the discharge from the inverter computer, although minimal, will cause even the freshest battery to fail given enough time in cold enough temps. Next winter I will either remove the batteries or set a trickle charger on them, or better yet, store it in the south and get the heck out of here.

I had my batteries freeze the second year and the cure is quite simple. Sell the house and. Most of your "stuff" and only go to warm places. Our first year doing it and I will bet my batteries never freeze again.

So where do you spend your winters??

For me it's AZ, but I LOVE the desert SW in general. When you first come here you think "my God, who could like this god-forsaken place"? Then it starts to grow on you!!!

Boowho??

Bill we spent last year at Silver Palms in Okeechobee FL. We will be there this year from Nov until the end of February. We are thinking of leaving FL and following the Gulf around to south TX some place. From there who knows. I have a brother in Flagstaff I haven't seen in several years so depending on the weather we might head there. I would as soon spend the bulk if next spring in the NM AZ area.

Phil, Flagstaff is cold during the winter and does get snow. Not a place I would think of heading in the winter. Now Yuma, that is the place! Craig

Craig it snows like a SOB there. If we can't talk my brother into meeting us south we will check the weather around April and see if it will work. Not heading into cold snow or ice if I can help it.
