Battery power

Hi everyone, first timer here. Can anyone suggest the best "budget" Battery for powering a 70 litre waeco camp fridge? I have a 120w solar panel.

I'd start looking at an AGM battery in 100 or 120 AH.     Something like http://balmainbatteries.com.au/Product/absorbed-power-gt12-100c/417.html   but shop around.
Lithium (iron phosphate) are becoming much more attractive every day, not sure they are quite there yet.        More discharge cycles from the Lithium style.

Make sure there is something in place to load shed / avoid totally flattening the battery as that will kill it real fast.
