VIDEO : HOW TO Replace the Main & Auxiliary Battery on a JL Wrangler / JT Gladiator

[Scoop315]

Go easy on the plastic pieces, they will be brittle. Careful with the big electrical connectors under the fuse/relay tray.

Thanks for the advice! I don’t think I want to do the auxiliary battery delete that everyone talks about online. But I’m wondering if a battery management system, similar to RedArc, might get the crank and aux out of parallel, and isolated from each other. I’m only thinking about it because I want to do a battery for fridges, which of course would be totally separate from the two OEM batteries. The hostility from people for saying you don’t want to do an aux delete is something else!

^^^^^^^^^
Definitely go easy on the plastic!

Thanks!

The redarc kit is nice. I also recently installed the genesis dual battery kit in a customers JLUR and it is a nice set up. Has extra posts in it for accessories to be wired to the battery

I need to pick your brain on this. Because the complaint is that the crank and aux are in parallel, but when I was thinking of trying to isolate them, and maybe use a different type of battery for one or the other, I was told it wouldn’t work, but not a real explanation why, except that both batteries have to be the same type (they can’t be paired differently, like AGM vs lithium-ion, or AGM vs LiFePo).


Also, I put a charge on the battery this morning, and even letting it sit for about five hours, it’s cranking. I didn’t swap out batteries, because I’m hoping to nurse this out to a warm day, or buy a new house with a barn large enough to get a lift! I’m done laying in the street to work on my stuff.

So the genesis kit “deletes” the aux battery but it gets replaced with the now bigger battery. The genesis power bank keeps the battery’s in parallel but it will isolate the battery’s as well. When voltage gets to low it isolates the main battery from the auxiliary battery so that you can still start your vehicle. It also allows you to pair them together to jump start your vehicle if needed.

I just read this basic concept on the Genesis website. I’m sold on it. Thanks, C!

So, I jumpstarted the battery and let it run for about a half hour yesterday, and the Bankster the Rubi sat all last night in just about freezing temps, and mid 30s throughout the day. I just went out and it fired right up. So, I drive my grandson into school tomorrow and decide if I run it until I have a problem, or go down to where cozdude works and order the Genesis. I have the money to be able to buy Genesis. But I’m always worried about plunking money down until I actually do it.
