Coach Batteries

Question: In winter camping in Az, will the coach batteries run the hydronic furnace all night? Please describe some of your camping experiences without hook ups and how your batteries responded ie. how long do they go before charging is necessary et.
Any helpful tips are appreciated,  I dont want to be stranded with no power.

The answer needs more information. How many and what size batteries?  How old?  What else will be drawing a load?  How cold is it?  And probably a lot more variables if I think longer on it Don

Thanks, Don, Im running the large DC8D pack (2) batteries. Although they are 2019 batteries im going to get them checked out for a known baseline that i can work from. My coach is a 2002 Intrigue and all though i have had many rv's, this one has features i have never delt with. I am hoping to find someone in arizona that has one so I can learn from their experiences. thank you so much for your time.

I am no expert in battery management but I can offer my experience recently with a cold weather stay in Kentucky and Tennessee at 19°. We overnighted at Bass Pro Shops and we're very conservative with our battery consumption. We shut off breakers to microwave and audio/ video. Only used minimal lighting and 12 volt lights only. Fridge on gas.  My two 8D batteries have approximately 144 amp/hrs. At 9pm batteries were only taking about 2 amp charge and battery monitor showed batteries fully charged and on float charge. Zone 1 and 2 set to furnace and thermostat on 66° zone 1 and 64° zone 2. In essence only real system running was hydro hot and whatever power consumption inveter draws at idle. Shut generator down and monitor showed 6 amp draw. Went to bed and awoke about 5am with batteries down to 11.9 volts. The 2 8D batteries just can not provide enough amp/hrs. Not much information, but all I got for now.
