Hi all,
I’m looking into fabricating a new battery tray for my V8 converted FJ40 after an “incident” on the trail last weekend.
Long sorry short - I’m wondering how far away from the exhaust most V8 batteries are mounted and what I can get away with as far as distance without heat damaging the battery.
The long story:
I’ve mocked up a piece of cardboard as to what I would LIKE, size wise, as it would allow me to mount a variety of battery types. However, it would only leave me with about 2 and1/4” inches between the back corner of the tray and the exhaust manifold. In terms of battery placement, it would probably wind up about 3” from the exhaust.
Just wondering if I’m overly worried about the battery getting too hot or if this gap is worrisome.
The corner of the old tray only sits about 3.5” away, with the battery riding roughly 4” away, so it’s still close. However, due to several battery related misshaps over the years none of my prior batteries have lived a full service life so I’m not sure if the heat is killing them (I sure do).
This tray as mocked up would be large enough to mount one of those huge 13x6.8x9.5 BCI group 31 batteries in the event I ever decide to go that route. I can’t mount the battery much higher due to hood clearance. I might have a half inch to play with, vertically.
I know a ton of V8 rigs mount the battery over here, some with overflow bottles, etc in front of them like mine. Naturally a shorter battery tray would free up a couple of inches but if the heat won’t transfer terribly across the 2 1/2” gap then it would be nice to have the option in the future. I'm not really interested in moving the battery to the driver's side or inside the truck as that would require a lot of re-wiring.
