Anyone got an thoughts on what sort of temp. a new CF40 will hold overnite. Can leave it on and will eventually run the spare battery down and turn off, which dosn't worry me, isolated from the cranking battery and will charge up next day.
Dont want to run it on freeze in case things thaw a bit so running on fridge only.
Ambient temp will be cold 0 to 10 degrees overnite in the Kimberleys.
Out of here on Sunday for 3 months in the NT,WA, and the Flinders Rangers,
with the new Trakmaster van ,lifes tough but we just have live with these things.

Michael B,
Used the same fridge thru Simpson, Alice and back thru
Boulia Winton etc in first half of May. Had it set on three (3) lights all the way. Froze water bottles at bottom of fridge but beer/coke middle and top were fine. We had one of those fridge covers on it. No problems with battery whatsoever with fridge on 24/7 for three weeks or so.
Tested it out at
home on both 240 and 12 (via old UPS battery I had in shed and in the truck before we left).
Just make sure the lid seals properly when you close it each time. Easy at night with the internal light.
Have a great time you lucky buggers.

Michael B,
Get one of those inside/outside temperature monitors (around $20 or less) with a remote probe from Jaycar, Dick Smith or wherever and
test it out before you go. Worked fine for us but I did'nt record the temps for posterity, sorry.
I'll do a
test tonight and post it for you. Won't be as exhaustive as some of the testing I've seen posted on this
forum (you might like to search the archives as there are quite a few forumites with this fridge who have posted results).

Michael B,
So much for the testing. A surprise raid by the rellies last night buggered the
test and made a substantial hole in my supply of life sustaining fluids.
Anyway, I usually work on the theory that each light (bar) on the fridge is roughly equivalent to 6 to 7 degrees C difference to ambient temperatures. I think its in the manual somewhere. Given your expected overnight temperature range, 1 bar should be sufficient. You can pump it up for daytime temps.
I'd be a bit reticent about turning it off completely overnight if you have food in it. Not a big fan of spoilt food or food poisoning. Anything you definitely don't want frozen should be stored closer to the top of the unit or on the shelf next to the light.
Preferably don't refill the contents as you go. Leave it till late evening when abient temps are low.
Our unit was strapped to the 'deathseat' in a Hilux Extracab and turned on for over three weeks. The vehicle was only closed up when in more populous camping areas etc with no discernible heat build up whatsoever. I used some styrene blocks between the unit and the back of the
seat to ensure some airflow around it.
As suggested above, you could take it out overnight but I was there to enjoy myself and not spend time manhandling the fridge and its contents. It is an option for extended stays in one spot though.
Sorry I could'nt be of more help. Have a great time.
