Battery relocation...

Any drawbacks/safety issues to having the battery located behind the seat on a CJ? Enclosed with a hardtop?

PO of my CJ did this with 1/0 welding cable grounded to the frame and another piece of 1/0 to the engine compartment.

potential fumes from an unsealed battery, potential arc'ing it it ever comes loose( or has stuff stored/thrown across it), more difficult to jump if needed, loss of already limited interior space. longer cables offer more resistance (less power for starting)...

I put mine in a built-up steel box which is welded to the frame and cross-member, under the floor, behind the driver's seat (should be photo in my gallery pics). It has an aluminum hold down bar, battery disconnect, and flush fitting, hinged access lid. I used 2-0 cable to the starter and a 1-0 cable to both the frame ground and bellhousing, directly behind the starter. It is vented below the floor. It has been time tested for 32 years in this location. A word of caution: you will end up with a long, unprotected positive lead that if allowed to short, will likely burn up your Jeep. I used split-loom over the top of the welding cable and all rubber-bushed (EPDM) cable clamps. The sheathing/cable does not contact ground anywhere. My winch lead connects at the starter and I have not noted any current limitations with this arrangement.

I used to do this with street/strip cars.

The only change I'd really suggest would be to use a "pass-through" post to go through the firewall, instead of drilling a hole and passing the cable. Likewise with any other bulkheads. If you can't find any, let me know (I have some.)

The battery, if being mounted in the pax area, should go into a sealed box and vented outside the vehicle! Even "sealed" "maintenance-free" batteries will still outgas when charged, and this is what can cause you the trouble (yep - even Odyssey and Optima batteries have vents in the lids. You won't lose electrolyte, but you'll still get outgassing.)
