Which WAECO ???? CF-60 or CF-80

Sorry, was no answer when I replied, but shows it is a better way to go.

I was thinking the same thing, at least there is no double posts.
One other thing is with these big fridges or any for that matter when they get empty the contents rattles around.
To stop this drink a good cask of wine re use the bladder by blowing it up and putting it in the fridge this will stop the contents rolling around.

Cheers.....Stephen

Hi Stephen, yep use them bladders all the time. I dont have a fridge yet, but use a 150 lt Extreme ice box. Fill 4 bladders with clean water freeze them before we go away. Top up with ice at the last provisions store before we head off road. This set up not only performs well for over 6 days, the bladders also suply us with cool drinking water.

Cheers...Lionel.

Thanks guys, going by the waeco specs the 110 actually draws less than the 80.

Cheers

Cheers Norm,Thanks for the info.

Hi Axel, sh"t mate what do you leave the lid open all day? I've had an 80 for over 5 years now and done some real time tests and have had it down to 1 aph and a max of 2 aph. I set ours at 5 when we have charge to the battery to it and 3 when not.

Cheers Bruce

Bruce ,have you ever actually put a thermometer in the fridge ?? what do you use to check your amp usage over a 24hr period ?? because tell you right now that the day an 80lt Waeco draws 1-2amps per hr while used as a freezer and fridge I will stand naked in the Queen street mall ,, not in this liftime will a Dannfoss BD50 as used in the 80lt Waeco only use the power you claim , absolutely impossible ,, at your claimed figure it would be using LESS than a 40lt Waeco [ BD35 compressor] and less than any 12vfridge on the market in Australia ,,, Bruce your dreaming.!!!

Just as an adjunct Bruce and Anne , I too have had our Waeco for nearly 5 yrs , use a Steca solar regulator to measure power usage and input , and if you care to have a look about facts and not conjecture go to www.waeco.co.uk/ and scroll down to power usage ,,,,,,,

Ok Axel hears what I done, the Waeco 80 was in a house for seven days (moving in) had it running from a 100 amp battery with a 8 amp charger. (do not have a 240 volt converter for the it)
The battery showed 12.2 volts by my multi meter and the charger set to trickle charge (which I believe to be about 2 amps) after seven days the battery showed 13.8 volts this was all while it was running and every thing was frozen in the freezer and ambient temp was 28 to 32 degrees (Nambour in January).
And I have run it for three days without charge on same battery, so go figure. And why do I need to have a thermometer when everything is frozen in the freezer and the beer is nice and cold in the fridge.

Cheers Bruce

Bruce ,in other words you have not even a 1/2 accurate measurement of amp draw of your waeco and yet you assume an impossibly low figure through voltage measurements over a 7 day period while charging a battery ,, with your method of measurement we could all claim almost zero power/amp draw , thing is its false and totaly wrong.

So lets see your saying that the battery charger is putting out more than two amps on trickle charge, and this is not a big charger, and from what you says yours uses 64 amps and 25+ with the freezer on gee my 100 amp battery must be closer to 300 amps have to tell the battery maker about that one. And you have to remember that they don't run 24/7 more like 20 minutes in the hour, so if say someone said it uses 6 amps per hour on a meter than it is only using 2 amps.

Cheers

Bruce you obviously cant read or do basic math , read my 1st reply , 64amp on average per 24hrs as FRIDGE + FREEZER ,, add anothe 25+ amps when used as ALL FRIDGE ,, which is almost the same as factory specs , get yourself an amp HR meter not just an amp guage ,,, have alook at www.waeco.co.uk/ and then tell me Im wrong.

Bruce,

The Undertaker has a most unfortunate way with words but I agree with him on the usage of the 80.

My guess is that when on trickle charge, your 8 amp charger will put out full whack when required and then drop back to trickle when the it senses the batt is near full. I found that a 4 amp charger used in the same way you did would not always keep up with fridge hence my assumption that your's is probably putting in the full 8 amps when required.

Just my thoughts.

Cheers,

Jim.

He does have a way with words doesn't Jim, the "Undertaker" hey I'll just call him no I wont go there hahahahaha.
So now I don't known what I am talking about ???? how come my 100 amp battery is not dead after 1.3 days? saying that it uses 64 amps in 24 hours.
ok Iam nearly out of fun time to day but in case you don't like your Waeco Axel cause it uses to much power I'll buy it off you for say 50 bucks

Cheers and all have a Happy and Safe New Year, Bruce

You still cant do basic math can you Buce ? tis realy time you did some reading on 12v batteries /amps /watts / charging ect as all your replies show that you know jack on the subject ..

Bruce and Anne,
You say ""had it running from a 100 amp battery with a 8 Amp charger.
The battery showed 12.2 volts by my multi meter and the charger set to trickle charge, after seven days the battery showed 13.8 volts this was all while it was running and every thing was frozen in the freezer.
And I have run it for three days without charge on same battery, so go figure""

Here is figured:

You have the ability to charge @ 8 Amps and trickle charge too.
The fridge draws less than 8 Amps, (~5 Amps?) so the battery charger will MAINTAIN the battery Voltage at a CONSTANT 13.8 Volts - indefinately.
If you had of checked the battery the day after it was connected to the charger it would have been the same 13.8v from that time on.

To use a battery charger to supply the power to a battery that powers a fridge will give you NO realistic idea of the power consumed by the fridge.

Reason being,
the battery charger is on 24/7 and ALLWAYS delivers whatever the battery requires to maintain it at 100% State of Charge, if it trickle charges @ 2 Amps when battery is fully charged and fridge not running or supplying the full power when the fridge is running (~5 amps) the charger is replacing ALL the power used by the fridge as it's being used.

Hopefully the fridge is off a hell of a lot more than it's on (example, if the relevant numbers are [and we know they are not?] fridge draws 5 amps, runs at 50% Duty Cycle then it uses 2.5 ah)

A battery charger when used this way works similar to a Solar panel, they both deliver the power REQUIRED by the battery to maintain 100% battery SoC and the battery will remain CONSTANTLY "fully charged" (~13.8 Volts in your case) when read while the charger is still attached.

(However a solar panel is only powering the battery during the day and not the night as the battery charger will)

There is no relevance between the Amps going 'in' V the Amps going 'out' when measured with a Multimeter or Amp metre and a Volt metre won't indicate the Amp movements anyway.
Mainey...

Thanks Chelle, what made you decide to sell the waeco & go engel.

Well a number of reasons really. The 80 litre was very big & had trouble circulating air in the back of the cruiser but I didn't feel it kept the food cool enough for all of the different sections. I didn't use the dairy bit at all.. Plus with a family of four, getting into the big one to get drinks etc just meant it had to work all the time.... Our logic was that with 2 smaller fridges we would keep one for food & one for drinks. We spent a long weekend recently on the beach & it was great. We didn't use as much power & the food (& more importantly the beer) was cold & easy to access. Plus with me being on the short side, I didn't have to search as far for the food. Why Engel, my parents had an engel & they haven't had trouble & our Waeco just didn't perform as we had hoped. Hope that helps. Chelle
