I recently purchased a 1998 GU Patrol (4.5 petrol engine). Can anyone give me some suggestions about fitting a dual battery system. Mainly the location that the second battery is installed.

The auxillary battery is installed on the passengers side right next to the firewall.
You will need to relocate the clutch vacuum reservoir to fit it in.
I fitted mine using a TJM battery tray. My vehicle is a 1998 GU 4.5L with Manual Transmission.

Same! One thing worth mentioning though is if you have ABS I think it is virtually impossible to find the room for the aux. battery. Our battery tray was from Offroad Equipment (I think) and doesn't accommodate a large size battery, only the smaller ones.

The TJM battery tray will take an N70 size battery.
Such as an Exide Extreme rated at 80AH.

My vehicle does not have ABS fitted.

From memory to relocate the vacuum reservoir you need to remove the reservoir and mounting bracket then cut two of the steel vacuum pipes. Connect longer rubber hoses to the reservoir and to the ends of the cut pipes. Install battery tray and mount reservoir onto side of battery tray.

Was not that difficult to do.

I have a 2003 GU 3LT TD and I have ABS. I got the pirhana tray and standard it fits an N770 100A/Hr battery. It fits on the passengers side, in a position almost opposite to the main battery.

Not sure if the Petrol motor is different.

I have extended the standard tray, so that I can fit a 130 Amp/Hr battery. From memory i think the tray is now 340mm long. It will now fit a trojan SCS225 battery which I will be getting in a month or so.

Note - This mob rate the battery as a 150A/Hr, but that is at the 100hr rate, not the 20 hr rate.

The mod was pretty easy to do. I got a bloke from a sheet metal works to fold down the ends of the existing tray, re fold one end back up, and the end towards the rear of the vehicle was simply folded flat, and a new side wall welded on. A bit of fiddling around to get the brace welded on at the correct angle, and I was done.

All up cost about $100 for the tray, plus $30 for the bloke from the sheet metal works. I will have cold beer for longer !
