Battery question

We leave our camper plugged up all the time, even when not in use. Will this cause any issues with the battery/on board charger when it gets cold/freezing?

Thanks, Philip

Shouldn't if you check the water in the batteries about every 2 or 3 weeks.

With a 2014 you should have a power center converter with 3 stage charging.

Float mode should not boil the water out of a wet battery with excessive current as float will drop charging current to that necessary to replace losses due to parasite current loss (internal resistance and about an amp of "junk" that runs in the background).

However, you should "check on" the camper about once a month to look for damage or leaks and during that check a peek under the caps will assure you that all is still "OK".

I suggest you read this post (and other earlier experiments by this gentleman): http://www.forestriverforums.com/for...tml#post482734

The WFCO "3-stage" chargers don't appear to work very well.

I suggest that you either upgrade your Converter to a Progressive Dynamics, or unplug your RV except for about a day a month.

Another solution is to install a disconnect switch at the battery and use a Battery Tender to keep the battery conditioned.

My 5er is stored away from home and has no access for electric hookup. The battery was fully charged when put into storage on Nov.1 and the battery disconnect turned off. Will be leaving for Florida the last week in January. Should I bring the battery home and keep charged or will there be a decent charge when we leave? I don't want it to go completely dead.

I personally would bring it home and put a battery tender on it. Letting a battery go dead is one of the worse things you can do. Sucks the life right out of it. Sometimes when they go dead, they stay dead. No way to bring back to life. Doesn't happen all the time, but does happen. Either way, you are doing your battery an injustice by not keeping it charged.

I use a battery tender but have not found a reason to use a disconnect switch. Am I missing something?

That's my thought, too. I'm going to retrieve it this week, keep it charged at home and reinstall it before we leave for Florida.

If you don't disconnect the battery you may have the converter and the Battery Tender both feeding the battery. That would defeat the purpose of the Tender.

Lloydg, very wise move on removing the battery to keep it charged. Come on down to our great state of Florida, But bring lots of $$$$$ we need it.

When you cross the state line you will see a sign that says "KEEP FLORIDA GREEN", that simply means bring lots of $$$$$!

Think "convenience" when having a disconnect switch. Otherwise you need to get the wrench, pull the cover, place the wrench (5/8ths most likely), and loosen and remove the wire. Reverse all this to put it back on. The switch is a 45deg turn and the battery is fully disconnected.NOW...if you NEVER want to disconnect the batt (except when replacing it) because you have a batt tender, then you really don't need the switch.

Battery Disconnect Switch

With the disconnect switch OFF, you can't use any 12V in the unit relying on the battery. This has no effect on using a floater to keep your battery charged.

You have to know what else is connected to the battery. Alot of the CO alarms are connected pass the disconnect. So it would be pulling amps with your disconnect turned off. You are better off taking it home or your battery will be dead when you go back.

IMO, if your battery disconnect doesn't disconnect all of the parasitic loads (like propane/CO detector), it's wired wrong. That's the whole purpose of the silly thing.

You would think so, But mine is wired directly to the positive terminal. I know that that is the case because I disconnected it at the battery post and it shut it off. My solution was to add a SPST switch next to the CO unit in the trailer. They could have made a mistake at the factory just as my disconnect pulls out for on and push in for off. I had to add a plate in front of it being my load shifted during travel and shut down my 12V. It's attached to the floor of the basement not on the upper wall. I another great design by FR. So you shouldn't make blanket statements like that. I would be more then happy to post pictures.......

Are you sure that the switch should not work that way? Was it suppose to work like a safety switch that can be turned off simply by depressing the button?
