I'm looking to relocate the battery in my sierra to help with weight distribution and while im at it i thought id upgrade to something a bit more powerful as I've just installed a winch and EL falcon alternator.
What's people suggestions on both battery type and where to put it?
It's a 92 SWB soft top that's been lengthened and chopped into a ute by the way.
Cheers
Cal

Have you considered a dual battery setup?

Optima d34 under the passenger seat.
The weight, complexity, cost and unreliability of a dual battery system isn't required.

+1 on d34.
I wouldn't buy one from any of the big car parts stores,
I've had good dealings with kpd4x4 and 4wd products on eBay

Floor needs to be cut to drop the battery through. Been done on heaps of cars.

Cheers guys.
KPD4x4 still do Optima Batteries too, I've just ordered a D34.
I'll wait until it arrives and then start playing around with locations.
I considered moving it to the left guard MrRocky but I have the older model ARB compressor which is already taking up that real estate.

I have a friend with acid burns to the back of their legs from an exploding battery under the passenger seat. I wouldn't do it as you need to have the battery box vented which means acid will escape of it explodes. The under seat battery was a factory fitted job on a police car, not a backyard job.

The battery box needs to be vented to outside not into the cabin.
a dual batt is only needed to run a fridge and should really be charged by a dc to dc charger. All other isolators really should be the same battery type age etc so they charge equally.
I just run a big batt swich that I can choose what combination of batt I want connected. No electronics to fail and drain power.

I'll stand by my opinions Whincup. I have seen enough dual battery systems die and wipe out one battery or the other over the years. I fully expect the dual battery system in my defender to die before I sell the car.
If there is a requirement for a battery to run a fridge, mounting a gel or lead acid battery charged by a DC/DC charger is all that's required.
I hve had no issue with underseat batteries over many years. Always optimas.

A simple 140a VSR connected from my starting battery to a 100ah AGM with Andersons just behind the drivers seat. The battery runs a 80L compressor fridge, electric oven, tool battery chargers, and a 240v invertor. I switch the fridge on for work Monday morning, and stays on all week until home Friday night, so running around 100 hours a week. The oven, chargers and invertor are only switched on as needed. I bought the van new and installed the system the day I got it home, so this set up has now seen 99,937kms and 4.25 years of use as of today, and I have not one issue or have I had to touch it. No DC-DC or anything fancy. It cost me around $400 all up to do, and still works as well as the day I fitted it. Not too bad for around 22,000 hours of use and still going strong!  Also I have just fitted the same set up into my SWB Vitara with my new battery box. viewtopic.php?f=14&t=49787But with the battery behind the back seat.
