they are in the same location regardless of engine.

I removed my ARB from my TD5 and then installed it in my V8

Not sure on the power consumption of a 35lt but the 50lt waeco draws an average of about 0.9A/hr so would be about 60hours.

thanks grover, that gives me a rough guide to work with then!

and thanks again to everyone else who has helped so far!

my plan at the moment is to fabricate a new battery tray (thanks to CJT's useful post with pics and dimentions of a tray he bought from the states) and fit possibly 2 optima red tops, hopefully they will do the job nicely for my trips!

Pauly85,

You can find come more information on everything I have used and will be using in the install here;

WT??!! Is it a deep cycle?

My Orbital really only just fit and that ment losing the ARB hold down and i didnt bother with a heat shield as the V8 doesn't have that turbo thingy to worry about

You can actually fit a 140 amp hour battery in the standard battery tray.
I use one like this

12v 140AH DEEP CYCLE/MARINE/4WD AGM BATTERY 2yr warr. (eBay item 290351422012 end time 12-Jan-11 14:59:13 AEDST) : Cars, Bikes, Boats

with 1350 CCA and 140 amp hours.

It should be enough to run the fridge and camp lights without the additional expense of a second battery, battery tray, battery charging system etc.
It worked for me because my old battery was on its last legs, whether its worth replacing a good battery I dont know.

It require a little modification, I cut out the bottom of the battery tray,
put thin rubber over the sharp bits that may abrade the battery.
I also wrapped the battery in a sheet of strong tarp I had.
The posts cant be fitted, so flat type battery starter cables connect the battery to the leads (supercheap auto, or repco)
The top wont fit back on, and its too high to clamp down, but it is a VERY tight fit as you can imagine, and I cant see it moving even in a serious prang.
The top doesnt fit back on, so its exposed in all its glory.
If you like I can post some pics, its one solution.
