Sarg, I went to the link and found this->
Heat Load:
the biggest heat load on a FRIDGE is the heat infiltration through the insulation. In fact anything that is inside the FRIDGE making heat eg. warm beer, will make the fridge work very hard to cool it down. The more efficient the design of the refrigeration "system" the less power used to remove the heat put in by leakage & warm contents.
Charge:
The ideal way to charge a portable 12/24v fridge is to run a dual battery system in your vehicle, one of which being a DEEP CYCLE battery. The deep cycle battery should be automatically isolated when the ignition switch is off. We advise that you should have the fridge directly connected to the battery with a fuse on the pos (+) line near the battery. Avoid running the fridge power line with any CB, UHF,
HF radio or GPS co-axial cables. All fridges generate some electrical interference.
Efficiency/Current Draw:
to test a fridge for efficiency you want to know the battery voltage and the current draw with the fridge set to maximum. Fridges are at their most efficient when they are at temperature (ie. the temperature dictated by the thermostat control) because the compressor is not running. The effects of external climatic temperature and the effectiveness of the units insulation will determine how long until the compressor will need to start up again to keep the fridge in the required temperature zone - which for foodstuffs should be BELOW 4°. Note - it is very unhealthy to let frozen foods defrost and then refreeze. It is also unhealthy to store refrigerated food go above 5°C. To obtain the optimum operation from your fridge, ensure that it is wired using at least 10 Amp cable. WE RECOMMEND the use of at least 20 Amp. SOLDER any crimp connection to avoid voltage drop. Always remember voltage drop is your worst enemy in vehicle wiring.
Sarg, what's wrong with the information posted by EO at the link you have shown?
or Have I missed something....?
What was it that you found - that I didn't ??
