Furnace blower?

I have found that if it is cold outside and the furnace is running a lot it will drain the batteries before the night is through.

Thanks for your reply. That what we were afraid of, we're living in our Lance while helping our son out with the grandchildren. You know Wally World, Craker Barrell , etc

One battery or 2 ?? Group 27 or what size battery's ??

I measured my furnace the other day it is a 20+ year old one on a Shadow Cruiser, so I don't know how it compares to ones on Lances - I think it was 3 amps while running. The current draw will be both the fan and the solenoid valve for the gas.

Fwiw, I've only had a battery die at night if the battery isn't taking a full charge.

I know that the Atwood 16,000 btu in mine draws 3.4 amps running.

Only one bat class 27 was going to upgrade to an AGM class 31. If we had been told ours was bad ...but that was not the case!Happy Traveling

That 's what I'm thinking so I'm thinking I'll put it on a slow charger 2 amps overbite an see what happens!

As we remember we've used this Lance since 2006 we it was purchased an it's done this only twice recently. That why I'm thinking either a bad bat or one that needs a good charging.

A Lance 881 20,000-25,000 about 5-6 amps.

Cold weather will shorten the time you can use a battery. If you could install AGM's inside and keep them warm, you'll be ahead of the game.

Pull the slide in at night if you can, the furnace will cycle less.

The two stage furnace can be more.

I have two grp 29's dedicated to the furnace and water pump. I can make it thru one night and the next morning if I run my Honda 2k just before I go to bed.
I use a separate third battery for LED lighting as well as the inverter to operate the TV/DVD .

I charge all 3 batts at one time .
