Dead Batteries

Hi All! We went out to the Four Winds in order to get ready for our next trip tomorrow and the batteries were deader than a door nail. The two batteries that are under our stairs that is, not the coach.

If we plug the camper into the house will that charge the batteries?



Interesting this happened because they are both brand new. When we went to check out the camper the batteries were dead and they replaced them.

As always TIA for your help!!

Cat

Try plugging in, and setting the "Use/Sore" switch to "Use", (it might be labelled"On"), and give it 24 hours.
Good luck!

Obvious something is drawing your batteries down pretty quickly while in storage. If you’re using your “store switch” you should be able to store without power for at least several weeks. I got tired of worrying about it so added a small (80W) solar panel and it has been way more than adequate fo keeping my two house batteries and coach battery all topped up. Summers have long sunny days, winter not so much so I probably will add a second panel in the fall. Not sure it’s really needed but certainly can’t hurt either.

The "store/use" switch does not/will not totally disconnect your house batteries, the CO/LP detector, digital clocks & motors to electric slides to name a few items are not disconnected through that switch & the batteries WILL be dead in a matter of days not weeks. The only total disconnect is to disconnect the negative cable that goes directly to ground or put a manual disconnect on that cable.
Repeated total discharge of the batteries severely shorten their lifespan, so either leave it plugged to shore power with the switch to "use" or disconnect the cables if stored for extended periods.

That has not been my experience.

If you have the ability to keep it plugged in while storing, just leave the use/store in the use mode. As was explained earlier there is always a drain even when the store switch is activated. I just replaced both of my house batteries after one died and the other was on it's way. They were 2017 batteries in my 2018 Thor Siesta. I replaced them with wet cell Marine 12 volt batteries that were on sale at our local auto parts shop.

You don't mention if you're prewired for solar. If you are, a solar panel would help out.

You mention plugging it in to the house. If you have a volt meter, measure them and see if there's any improvement. It won't explain whether the batteries can hold a charge, only they take one. That would be an insight.

If you use a storage lot, all that's out the window.
