Thread: Optima Red/Blue/Yellow Batteries

They will fit - same as an N86 will fit (just) if you move the wiring out the way that sits on the inside of the guard to the top (quite a big job), trim the radiator support panel down and move a couple of small brackets down where the bottom of the battery sits. I used to run 2 x N86's in my RRC - I only run 2 x N70's now. I can take some pics tomorrow arvo of my RRC and how I did it. The D31 is slightly shorter in length than the N86 so would fit fine with these mods done, but wouldn't fit without getting a grinder out.

Cheers, more interested in the physical tying/clamping down of them, supercreap stuff just doesnt cut it in the rough stuff

Not much help there sorry, when I had the N86's in there, there was only enough room for gravity to be used to hold them there...

I run standard N70ZZ's now - clamps are just bits of angle iron screwed down with bolts welded to rods that hook under the tray.

I currently run a 34 red top as starter and D27F yellow top as deep cycle.
Because I had mounted my winch relays beside radiator on left side, D27 would not fit there, so swapped roles. I shortened the existing battery-starter cable to suit.
Re clamps ... welded my own using angle and square tube.
Photo to follow when I get home and can take pic.

You can buy a restraint at Supercheap which has a reinforced Nylon bridge and two bolts with "Us" on the end.

You have to shorten one bolt and rebend the U but the rear bolt will fit as is into a hole in the guard. The front will fit into a hole in the radiator panel when bent correctly.

Used lengths of angle iron and normal battery poles when I had to lay the Kickass AGM flat to fit in the limited height of the space in the rear of the drawer set in the Defender because nothing off the shelf would do the job. Can't see why it wouldn't work with an Optima. Just cut to required length.
