I have an ARB fitted Exide Extreme in my 2003 3.0GU which runs a 60l engel. I noticed a bit of the (usual if you drive an old holden) white fuzz on the battery bracket after a cape york trip last year and put it down to the corrugations and/or temperature so I cleaned with hot water and put a spray of INOX on it. Six months later it has returned and I can see water marks from acid or whatever on top of the battery. So I am wondering what is causing this spillage/seepage? and can I do anything to prevent it? Is the battery getting hot and if so why do ARB not include a heat shield with the DB setup?

It sounds like the battery may be getting a little warm and the acid is boiling out the vents. Maybe you could get some reflective foil type insulation and silicone it to the battery or fix it on in some other manner to reflect some of the heat away.

I fitted the genuine battery shield (with vent to the outside) which comes fitted to the starting battery from Nissan.
THe shield is plastic but it is designed to keep away from the battery (keeps an air gap) and has an external tube, the shield also has foam around it.
Works well. From memory it was about $40...

To Gu Patrol, You mean you fitted a shield the same as the main battery shield to the auxillary battery? Michael

Darren,
My battery failed after 4 years and in that time the sealing washers needed replacing twice due to cracking. Some evidence of leaking acid especially after battery was overfilled during a routine service.

Purchased a sheet of aluminium from Dick Smith and pop riveted to ARB carrier to form a heat shield between battery and exhaust. Also placed marine carpet under battery.
Appears to help. Any reduction in heat buildup must be a good thing.

Cheers Bob L
