I have the original battery's in my 2008 Georgetown 315DS SE which I bought back in May. One night while boondocking at Tahoe this summer, the battery's ran down to where almost nothing would work, which surprised me since I have 2 coach battery's, this was when it got down to 30F with the furnace running. I had to start the engine in the morning so I could start the generator. Good thing they are not connected! Now on my old Rockwood Roo this happened quite often but I had only 1 battery on it.
Khager, You bring up a whole different subject here as it relates to power usage. I am not surprised your batteries didn't last through the night with temps in the 30s as the stock 2 batteries that came with the Georgetowns really aren't enough to be able to keep up with the furnace at those kind of temps. The furnace is THE largest power draw on the batteries drawing a lot of amperage while running. If you plan to do a lot of camping in winter you really should have a site with hookups or plan to run the generator all day to keep up. When you consider light usage, water pump, LPG detector running, all the cirucuit boards on the appliances etc the stock 2 batteries just don't cut it in low temperature conditions. The stock halogen lights are not the most energy efficient either.
sorry to hijack the thread on battery charging.
