How long do your house batteries last?

We have a 2010 Georgetown 330TS. What camping we've done so far has always been with full hookups. At all times, the status of the house batteries according to the electronic monitor panel have always showed full charge.

On the last night travelling back home, we had to stay overnight at our first "Wal-mart" campout........actually quite fun. The overnight temperature was cold enough (35F) that we had to run the furnace, set to maintain 68 degrees F. Before going to bed, the control panel showed full charge for the batteries.

At around 4AM, we heard a faint alarm beeping, and I found it was originating from the furnace compartment. When I checked the control panel, the LED status for the batteries showed 1 LED out of 5. I immediately started the RV engine, moved us away from the other campers, and started the generator to run the RV on AC power. Battery status improved to 5 LEDs and we slept for a few more hours.

Is it normal that the batteries should develope this failure in that amount of time? I would have thought that house batteries should be able to support "dry camping" with just the furnace for at least one overnight.

Anyone???????

The furnace will drain the battery quite quick, if it runs often. I have experienced the same on cold nights.

It also would depend on general condition of the battery as well as size.

Ken,

Out of curiosity, does an MH like the Gtown come with batteries or do you supply them yourself? I've always wondered.

More to your question, what are the total Ah for your House batteries?

To Triguy..........

Yup. Forest River supplies the batteries in their motorhomes. I Don't know the toal amp hours........documentation is not their strongpoint! nI do know that mine have stickers on them saying manufactured June 2008.

To Iggy.......

Are you sure your house batteries are 6 volt batteries? Your photo looks like they are 12 volt. I see what appears to be two rows of cover caps on each battery, and if there are 3 cells for distilled water under each cover cap, then that's 2 volts per cell times 6 cells per battery equals 12 volts.

Correct, the pic shows batts in parallel, not series

My Georgetown came with 2 group 27 12v batteries. No problem running a furnace overnight with some lights but I did replace them with (4) 6v golf cart batteries pretty quickly.

YEP they are 12 volt batteries and not 6 volt.
I have no idea why I said 6 volt....
Maybe I saw 12 volt batteris and saw 2 so I divided by 2....
