    Question about how many AH a 12v fridge uses. I have a three-way fridge in my PUP. The propane part of it doesn't work. It won't light. Assuming I can't fix it, I'm considering running it on 12v for 2 days while we are at a dry site.

    The fridge will already be cold, with cold food in it. Exterior ambient temperature will likely be 20-25C (68-77F).

    Does anyone know approximately how many Amps my fridge will use if it's at a med-low setting?

    I'll have a group 27 battery hooked up. My other usage will be as follows (as per the handy list that davido posted):

    1AH - waterpump for 10 minutes run-time
    2AH - LED lights for a few hours
    1AH - CO sensor, Propane detector, smoke detector

    @GreatBigAbyss,

    Just to be clear, there are:
    • 12volt compressor Fridges
    • 12volt settings on 3way Fridges
    • 12volt Thermoelectric fridges.
    A 12volt setting on a 3 way fridge would kill your battery in a few hours. They draw around 10 or 11 AMPS, constant!
    The dometic 12V compressor fridge i have is rated for 0.85 Ah/h (at 12V, 41F interior, 90F ambient)
    Themoelectrics draw around 3-4 amps.

    Try cleaning the burner. It's very simple to do, and fixes the issue around 80% of the time.

    Start your own thread, we'll all chip in to help!

    Ahh. That's what I suspected.

    I was trying to get it lit last year. I'm not sure how it disassembles. I'll tackle it again this spring when it warms up and the snow melts. Will start a new thread at that time. If I can get the propane 3-way fridge working, then it will make dry-camping a whole lot easier.

    My DC outlets are connected to the main DC line coming off the battery, I do have a master disconnect at the battery that shuts all DC power off to keep parasitic drain from depleting my batteries.

    I use a BatteryMinder Plus to maintain my batteries, & they happen to be on sale right now:
    https://www.northerntool.com/shop/tools/product_200332201_200332201

    Once I get my solar panels set up (I'm going for a permanent rooftop installation), I shouldn't need the BatteryMinder any longer...I'll let y'all know when I get it set up & running.

    I'll post pics when I get them installed......might be a coupe of weeks or so before i can get to them. Now that I've got everything to get them done, it's turned winter around here again.....

    Wow, is that all!? I had no idea. Maybe they ARE worth the cost...

    I've done a little research, and the NOCO Genius line of chargers/maintainers seem to be the best. They're the type that you can leave plugged in 100% of the time.

    Yeah. I checked them out. Nine of them showed the problem I was having. It's almost like the burner tube is filled with insulation. The pilot would light and burn with a large yellow flame, burning the insulation. I don't know what is supposed to there and what isn't
