Hi, I have no expertise at all in this area but I am not sure if a single 120ah has enough capacity to run the 90lt effectively. I have an 80lt Waeco & I am just organising 2x 200ah 6v to run mine. If you go to the Century web site they have a table that you can use to calculate usage & a calculation of suggested capacity of power needed.

Hi Greyghost, and others, A 80lt Waeco has a BD50 Danfoss compressor,It will use 5 amps running, And a 120 amph deepcycle Batt. will give you around half the amps of 120 = 60 amphs give or take a few amphs. If its summer it will cycle much quicker, and winter will cycle less, if its used as a freezer or a fridge..... So it hard to say just how it will do on a set battery.... Hope this gives you some insight... Bob n Bev

hi techies, can you advise how long will a 120hr deep cycle battery run a 90ltr waeco 12volt compressor fridge ?? thanks greyghosts,
There is no guaranteed time factor here. As stated above is correct, fridge/ freezer/ summer/ winter/ how often you open fridge/ what you add to fridge / state of charge when you stop /etc etc. The power consumpsion of 5amps does not change, its the run time that varies. You will need to recharge on a daily basis.
JC.
