Battery question
My wife and I picked up our 2017 Forest River Flagstaff Microlite 23LB this past weekend. At the dealer, they had it plugged in to 30 amp power and had the AC on. They also demonstrated how everything...

A single battery won't last much more than a day depending on load usage. I added a second battery in parallel to the first. Even with 2 batteries I sometimes need to use the generator in the morning to bring them up to 90%+ if the family watches a movie in the evening or the fan is running most of the night. My batteries very rarely get below 12.0v, but running the furnace blower will certainly use a lot of juice.
Here is a Meter you can plug into a 12v outlet and keep an eye on the battery.
Letting the battery voltage drop below 12.00Vdc(50% charge state) will shorten the life of the battery.
Here is a 12v battery voltage State of Charge chart:
12.6+ = 100%
12.50 = 90%
12.42 = 80%
12.32 = 70%
12.20 = 60%
12.06 = 50%
11.90 = 40%
11.75 = 30%
11.58 = 20%
11.31 = 10%
10.5 = 0%
When my batteries are tired, I'll replace them with two 6V golf cart batteries in series.
