2009 JKU dual battery?

Has anyone done this? I just picked up an 09 JK Unlimited Rubicon and there really doesn't seem to be enough room under the hood for two batteries side by side like they did in this thread... If anyone has done this in an 07-11 model I'd love to see pictures of how you made it fit!

I just carry a solar panel charging system for my trailer and an extre "GEL" 12vdc battery for the jeep--

What are you planning on that would require a "dual battery" setup for the JKUR ??

IMHO why even bother with dual battery just leave the engine running while winching.

Items yet to be installed include a Winch, HAM radio, integrated inverter, additional lights... Mainly want to be able to leave the HAM on when stopped at a campsite without worrying about killing the starter battery. Plus I've got the 2nd battery and isolator that I pulled from my truck so it seems a shame not to use it right? =)

No it's notta shame--the jeeps electrical systerm doesn't modify very easy-

The computer system on the JK/JKUs is like a racial cult--it just doesn't like any other systems messing around with it--

I think it'd be better to solar power at a campsite anyway, cause thats what I do and I never jeopardize my jeep power source !!

I'd love to see photos and/or writeup on how the install goes and how they manage to fit it =) Their website is rather lacking in documentation on the setup..


Thanks =)

Go Here. And soon (hopefully) they will have their site updated.

I'm going to an Overland workshop/rally next week, hopefully there will be a vendor there that has info on dual batteries...

I don't want to get 1/2 way to Central America, and have my start battery quit..... without a back up... for that matter... not even in Central or Southern Baja nowadays...

Jim what Size/Type of solar panel do you use. I thought of just getting one of those small roll up type. Do you know if these would do the trick?

The rollup panel types can now be optained for under 200 bucks (60 watt)

Go to google and try "mobile solar panel panels" and there are LOTTA different suppliers--also try "Adventure trailers"--great outfit and kewl guys-

They moved from LA to Scottsdale ,Arizona and they build a killer "teardrop" trailer-

I got my rigid panel from Northern tool-about 6 years ago and the rollup panel type was very expensive and few choices--



It's a hard (alum) panel 60 watts and powers an Engel cooler/lights/recharges trailer battery/Xterra/jeep/boat battery--

60 watts, which provides about 3 amps VDC in full sun-

Yeah, I got mine missing a couple parts and no instructions. Fortunately, they are located about 30 miles from me so I can hunt them down if the need arises. It's a tight fit, but it's supposed to work juuuusssstttt right. I'll post up when complete.
Tragically, no one else seems to take this market segment seriously. The next best option is to buy just the dual battery tray and a wiring kit from painless.

I'm glad to see someone else is putting a kit together. I'd compare the wiring option to painless. From the research I've done, the biggest value/pitfall is in the solenoid selection. A common issue with this is having the accessory battery die an early death because it's draw-recharge cycle is not correct. I'm not a tech geek to explain it well, but do some additional research on the solenoid function before pulling the trigger. Gl
