I have a 2004 Rubicon 4.0L With Air Conditioning. I have a bad Battery. I want to do some upgrades. I need advice.
What I currently have (Electric Load)

1. Lights:
a. 2 Ciebie E code Lenses with Osram 100/80 H4 Hardwired to Batt 12 guage crimp, sodder, and shrinked using the headlight switch as a relay.
b. 2 Pia Driving, rewired all 12 guage crimp, sodder, and shrinked, hardwired to batt using relays and switches. 135Watt H3
c. 2 Pia Fog, rewired all 12 guage crimp, sodder, and shrinked, hardwired to batt using relays and switches. 135Watt H3

2. Winch
a. Warn 9.5TI

3. Stereo:
a. 2 Big amps, 2 10’s, and a bunch of speakers. Loud as hell. (It all came with the Jeep)

4. Battery:
a. One Dead Optima Red Top


The Problem: (I know why)
1. When I drive up into the woods with all of that shit running my battery doesn’t charge.

2. My battery is dead now and I need to buy a new one.


What I would like to do:
1. Alternator upgrade;
a. Load Boss 165A?
b. Mean Green?

2. OBA
a. York Compressor?
i. With Kilby relocation bracket and belt, will it all fit if I have a AEM Cold air intake with that stupid vertical metal separator in the front passenger side of my jeep?

3. Dual Battery
a. Die Hard Platinum P-4 34/78DT?
i. I have AC. I do not want a AC relocation Kit. Can I fab my own bracket and turn them the other way side by side and just miss the AC Lines? Has anyone done this?

4. Battery Isolator
a. Hell Roaring?
i. I think I understand that you want you your winch hooked up to your main battery. I think I want to have all my shit (aux lights, and stereo), wired to a separate fuse block so I only have one large wire going from the battery to the fuse block so I can eliminate all the 12 guage wires to the battery. Is this appropriate?
ii. If I need all the power at once I can switch the batt’s together. Or I can just be using the main batt and have one fully charged for reserve?


I am so sorry I had to write all this crap out. I have spent hours on the forums trying to figure out the best way. This is far as I could figure it.
Thanks in Advance

Randy

P.S.
If you guys can help me dial in the perfect system, i will do write ups

I have been waiting for this thread. No doubt alot of good info will be posted. My one question , is that tray opposite of the stock battery location a tray for another battery? I'm definitely thinking of having a back up battery when I buy a winch and optima

Edit your battery is dead and can not be recharged?

I was looking at that myself. It didn't look big enough. I also wasn't sure if it was a sensible location. It would seem like you would want it all together. Not 5 feet apart. maybe it doesn't matter? I think I would like to have all my electrical crap in the current battery location. Maybe try to cram a air tank and regulator over in that side.

Its not a jeep, but my 97 ram came with two batteries, one on each side almost right behind the head lights. As long as you have a heavy wire between them the distance doesnt matter too much. I think i have a 2ga wire between them. I'm not positive though.

The best way to mount 2 batteries in a tj is the dual battery tray: 97-06 JEEP TJ DUAL BATTERY TRAY @ NTW
There are cheaper and more high end options to this, but this is the first that popped up.
Second, why would you run all those lights, stereo and winch at the same time? Ditch the stereo junk if you have an offroader, it is annoying on the trails and will just get your rig messed up when someone decides to steal it.
On your 1:a light listing, I hope you are using the ignition to signal a relay, not as a relay.
As a side note, optima batteries of the last couple years are not nearly what the old ones were. There are better options out there for batteries.
