AGM Batteriy in Nissan Patrol

The tray itself is very well engineered. It's the mountiing points on the guard that concerns me.

Not sure if the series 4 aux batt set-up is much different to the series 2 etc.... but I'd be reluctant to fit a 2nd full-size battery (AGM or wet cell or whatever) in the under-bonnet position.

My 1st GU (2000 model) had a wet cell mounted in a cradle right behind the air cleaner. I'm not into rough driving, but did take the rig to Cape York twice....and there are one or 2 patches of corrogations up that way.

My GU suffered from torn inner guards, both the base and the side. The tray that was fitted to mine utilised about 5 of the factory captive nuts....they all broke away on the surrounding metal.

Eventually, I fitted a 35kg AGM (Fullriver 120a/h HGL) inside the rear of the Patrol, behind the cargo barrier in the area of the footwell of the passenger's side 3rd row. I connected it via a heavy pair of cables using a Anderson Plug arrangement.

I went looking for a new deep cycle recently and was keen on the AGM types but was also told by each supplier I visited that if I put it under the bonnet they would not honour the warranty as they can't handle the heat .

Yes I was also told the same thing, although one of them said they would warranty it for 12 months only. Me being me I went ahead in any case and of course killed the battery. Such is life and lesson learnt I guess.
