house battery problems 2019 Jayco class C

[rpoudrier]

My house battery drains while in storage. All power is off in storage and not sure what is draining the battery. Any ideas?

There are lots and lots of posts on various forums re this problem and the simple (30 minute) solution is to install one of these; and it sure saves a lot of troubleshooting time. Just my $.02 of course.

There are more "elegant" isolation switches available, but this one works. I had the problem with both house and chassis batteries on my old WBGO Class C and installed this disconnect at both locations. If the rig was not in use, I disconnected the batteries. Worked well for the 6+ years I owned the rig. When I bought my Class A Jayco, it was one of the first things I installed (only needed it on the house batteries.) Your batteries will love it.

Even with the disconnects, there is a "self-discharge rate" with the batteries, but it is miniscule. When isolated, healthy batteries will stay charged for months.


Good times and safe travels to ya.

Welcome to the forum!
You did not say if it’s a 5th wheel, TT, class A,B,or C. You did not say how long a time from full charge to no power. I had an issue with chassis battery. It was drawing a pulsating .25 amps and would go completely dead in two weeks.
Lead acid batteries lose voltage just sitting, even if nothing is connected. I tied our chassis and house batteries, installed a shunt monitoring system, and can check the voltage of both sets of batteries on my phone. It sat for 3 weeks and went from 12.7 to 12.45 volts with near zero load.
If you cannot plug your rv into a standard 15 amp 120 v receptacle to keep the batteries charged, then the suggested thing to do is remove it, put it indoor somewhere and put a trickle charger on it. Assuming you have no solar either.

Welcome to the Forum from Western New York State!

It's called parasitic draw. There are a few items in your coach that require power all the time, some for safety reasons like the propane/CO detector, electronics that need power to retain memory like a stereo or TV, and maybe a smoke detector if it's hard-wired in.

Do you have a battery disconnect for the house battery? You might want to install one if you don't. As others have said above there is some items that will draw a small amount of electricity when parked and some battery disconnects leave some electricity to bypass the battery disconnect to power CO and propane detectors. Some people with RV's use a trickle charger/tender to keep the battery charged. If you don't have a multimeter or clamp on amp meter you ought to get them so you know what is happening with the battery. Watch some YouTube videos on how to use the meters if you are not familiar with them.


You didn't mention what type of battery you have: lead acid, AGM, Gel, LifePO4 ect. If it is a lead acid battery and the battery totally discharged the the battery might be bad.

The other option is to add a small solar battery tender to keep it charged up in storage. I used to keep a small 40W panel on the roof of the TT in storage, but our new TT has a big 200W panel on the roof. In both cases the battery was fully charged all the time. For the MH in our storage yard, I have seen a couple with a small portable panel propped up inside the front windshield. I would assume that there is enough light to keep the batteries topped up that way too.

This is what I did. I found an inexpensive 20 or 40 watt panel on Amazon. Because of the way our rig is parked in the storage lot, I can hang the panel off the hood and it faces east.

Keeps the chassis batteries nice n' full.

My 2016 Alante 26ay only charges the house battery on shore power. I plug in a maintainer to one of the 12vdc sockets and the 120 vac receptacle on the passenger console to keep the chassis battery charged at home and during long stays at camps.

I put a 30a resettable circuit breaker connected to both studs on the EM start solenoid, and close it when storing the RV. The converter keeps all three batteries charged.

our class c is parked in our driveway and plugged in to dedicated garage outlet. I have a battery tender (trickle charger) plugged into 110V coach outlet and connected to coach battery all winter. 5 yrs and zero battery issues. check battery cells for water quarterly.

So, you turn the converter that runs off shore power and charges the battery off?
