Default battery relocation question

im prob overthinking things as always but going to move the battery from the motor compartment to under the back seat of my cherokee. need more room in motor bay for fresh air. part i am worried about is the wire from alternator to the battery. do i need to run a larger gauge wire then i have on it now like the sice of the started lead or even larger? i would guess the wire will be between 10 to 15ft long by time it goes under truck and back under seat. any thoughts? thanks guys for any ideas or thoughts.

I used wire for welding leads for more. It is made to handle a lot more power than your jeep draws and it is very flexible and easy to work with. I wanna say it was four ga.

Go from the alt to the starter. It's the hot lead from the battery and it's one less wire to run. Go with the above for cables.

Use the biggest gauge you can afford. welding wire works good but it's certainly not cheap. When i did a relocation on a TJ it was $3 a foot for 2 gauge. you don't need to run a ground lead all the way back to the engine. just run a short cable to a solid spot on the body near the battery and a short cable from the body to the engine.

When I bought my welding wire it was 25 feet for 30 or 35 bucks from airgas.

I got two new cables for my boat that were 10ft 0 gauge custom made at the marina for $85.

FYI, the high strand marine stuff is every bit as flexible as welding leads, with a better coating.

For the length, i would use a minimum of a 2 ga wire, with 0 ga prefered.

imo it is a waste of time and money. You want fresh air run vents which would net you better gains then then relocation of your battery. If anything run a sec batterey under your back seat but leave battery in stock spot and save some wasted effort.

because of the v8 swap i had to turn batt at 45 in motor bay and i can fit a peice of papper between the altinator and batt right now. so i have no room to adj belt if i ever need to. plus the batt is also almost touching my exhaust header so its alot of heat on the batt. i will also be puting fresh air vents in hood to help with engine heat. thus the prob with v8 in cherokee lol but it is alot of fun to drive!

I cant remember for sure but welding cable sheathing isnt up to auto stanards for chemical and fire. It wont stand up to being under a vehicle. you could put it in a plastic conduit or metal one if you can. even if you run it inside run it on the hump so it doesnt get foot and salt contact. The marine cable would be better. Just watchin out for ya
