HOW TO Replace the Main and Auxiliary Battery on a Jeep JL Wrangler and JT Gladiator Truck

Having your Jeep battery die really isn’t that big of a deal, especially if you have a set of jumper cables handy and another vehicle near by that's willing to help out. But, what do you do if you're out in the middle of nowhere and all alone? That just happened to Cindy and I and if you can believe it, on our Jeep JL Wrangler that's only about two years old! Fortunately, we did have our super compact, Type S Jump Starter with us and that was able to get us going again. However, once we got home, we discovered that our battery still wasn't holding a charge or at least, not enough to fire up the engine. All the lights worked, the radio played, windows opened and closed and even the dash lit up just fine - there just wasn't enough juice to get it to get it to crank.
Well, as some of you may or may not know, the Jeep JL Wrangler and JT Gladiator Truck WITHOUT e-Torque will have two batteries under the hood - a large traditional size battery that's used for cranking the engine and a smaller auxiliary one that powers everything else, including a relay that connects the two batteries together for cranking. Needless to say, even if your main battery wasn't dead, you could still have problems starting your engine if your auxiliary battery is dead or dying. I should note that we were actually seeing strange messages on the dash EVIC including one for, Aux Switches being temporarily disabled due to "Battery Charging" and another saying, "Service Shifter". So, when it comes time to replace one, you're more than likely going to need to replace both and for us, we decided to use the opportunity to upgrade our main battery to an Odyssey. I wish we could have upgraded our auxiliary one too but there really isn't a whole lot to choose from and so I just got a Super Start Platinum AGM battery (Group Size 400 SSB AUX14) from my local O'Reilly Auto Parts Store. In this video, you'll get to see just how easy it is to replace the main battery AND what all you'll need to do to replace the auxiliary one. We hope it helps you out.

Man, I don't even own a Jeep, but you have to be one of the best instructors on KZbin. Great work

[@wayalife]

Thank you. I'm genuinely flattered that you'd say as much.

agreed supradav403. i want a Jeep now after watching the Wayalife videos. He makes me think I can do it and im a moron when it comes to cars/ trucks.

[@gooseberry769]

I agree, he is fabulous. Get this, I used his instructional video to help me install a metal cloak lift on my JL even though he was installing a lift of a different brand. And yet his video was more helpful than the manual from Metal Cloak.

That is awesome! Glad we could be of help to you.

[@chuck6985]

What an incredibly helpful and well-made video! THANK YOU! My dealership wanted almost $800 to do this -- using subpar batteries, no less. I bought the AUX you installed for 129 at O'Reilly, and I got an Interstate H6 from Costco for 169. You saved me almost $500! As a small token of thanks, I just bought some merch on your bonfire store ... and you've made a lifelong fan. Thanks again!

That is a really dumb design for that second small battery

[@wayalife]

LOL - not exactly the easiest thing to get to, that's for sure.

[@ProficientEnough]

Yeah. It sucks. When I was changing mine out and tightening the last bolt on the battery I accidentally touched the other terminal with the socket wrench arcing the terminals and fried the row of fuses for another $60 out the door.

I just now had to do the replacement for my 2020 JLU sport with 70k miles. Been reading on the forums everyone is saying not to go through the top through the fuse box but from below through the fender skirt and to order extra Mopar fasteners because they will snap. I followed this video precisely and it was a sinch. Got it done in 20 minutes! Thanks Eddie!

[@wayalife]

Glad to hear our video was helpful to you and that it only took about 20 minutes to do. That's about how quick I did it as well.

THANK YOU!!!! My husband can usually fix anything but he's the type to just tear in and get it done and I'm the type to calmly read the manual (or watch the video!) and this video saved our Sunday! He was bloody knuckled and swearing for an hour trying to get new aux battery in meanwhile I simply said "Hey, are you sure that's the right way because this dude in this video has the metal thingys to the left and you have mine to the right..." That's how we figured out he was given the wrong battery at the parts store! Exchanged the battery and I made him watch the whole thing start to finish and we got it done! THANK YOU!!!!!

[@philliplehn3600]

We are lucky here in Australia with the right hand drive. The main battery is on the other side and the auxiliary battery is sitting underneath it. We don’t even have to touch the fuse box to change these battery. I tried by passing the auxiliary battery by pulling the fuse 42 and disconnecting the black lead to the auxiliary battery, but caused strange things to happen.

I thank you for your time and awesome video...you make it look so easy hahaha. Thanks again..also at the end of your commentary you are absolutely right my gladiator was doing all of the above including malfunctioning of the start/stop function. Thanks God bless 🙏

[@wayalife]

Awesome! So glad to hear our video was helpful to you and really, it is that simple to swap out. We literally filmed this video in real time meaning, it only took about 15 min to swap out both batteries. 👍

[@djonesey5]

Eddie, again, I want to thank you for this video. Swapping the batteries from above became an extremely manageable endeavor for me thanks to you, in what I'm sure, knowing me, would have been a "train wreck" without such guidance. It was such a pleasure to know that before I began, that I had every tool I needed already out, not the least of which being an E6 reverse torx bit to swap the ESS battery's terminal studs. Please know that I have ordered the electric torx wrench that I've always wanted from your sponsored link as the least I could do.

[@chrisjones2252]

First great video Eddie. This is for all other's be careful when removing the 2 main battery posts. The auxiliary battery is still connected in line with system for JL's and JT's. You can get a multi-meter and read the positive and negative posts after disconnected and still get 12VDC. The aux battery runs the Electronic Start/Stop system. You can even get in with main battery posts disconnected and start your engine with key FOB nearby. I remove the aux battery posts off the firewall. Replacing the stock AGM batteries with better after market ones like Eddie did should get you 2 to 3 times the life then stock. Great job. Love seeing vids of the puppy growing up.

[@DougTucker1]

Sorry for the ignorance here, but you posted that as a warning without explaining what the concern/threat is? He didn't seem to take any precautions, just removed the post, removed that battery, then went on to removing the aux. So what should I be concerned with?

[@HeartSpirits]

One of the best instructional videos I've seen on here. Not only made the nightmare of swapping out my aux battery about as easy as it could be, but also helped reassure me that the screwy readouts and behavior of my jeep wasn't something worse!! A+++

When something stops working (like batteries) it’s often a huge pain to make an appointment at a dealer for something that may be under warranty BUT you just can’t wait for an appointment on their schedule! Was glad to see your symptoms were the same as mine and it's what convinced me to jump in and deal with the PIA of digging for that second AUX battery! (Fortunately, while diggibng out the main battery, I found out that in the Diesel the AUX battery sits in a compartment just under the main battery!!!) No fuse box removal and pretty actually pretty straight forward! Thank you for taking the time to do these videos!

This is exactly the comment I was looking for, my JLU diesel, noted the fuse box and air filter system are in different positions than Eddie’s, noted the auto start on and off says battery charging and aside that, no warning ⚠️, the main battery read 14v in the main screen, My Rubicon is a tank that can get me everywhere but if I am in the middle of nowhere without a jump starter, it is useless if the car does not start

The Group Size 400. Or at least, that was what it was at Orielly.

[@1947airman]

As of Dec 2022, two batteries came up at my local O'Reilly's computer: AUX 12 and AUX 14. I wasn't sure which it was so I went home to do some more internet research and found it's the AUX 14 with 200 cranking amps. AUX 12 has 180 cranking amps and is this not correct but will fit in the space.

[@Longhorn90]

Awesome video. Clear instructions, socket sizes, tips, etc. I didn’t think getting at Aux battery thru fuse box was that tough, and almost seemed easier than the fender well approach some people do. That bungie cord tip was great! I did the same trick for holding back the three wire harness on the firewall side. My findings… 1) the four wire harnesses that so nicely stayed in your tray or were easily pulled off for you, did not stay in my tray and instead were tightly attached to underside of my fuse panel. Yes, I had the four long screws fully detached from the harnesses. Pulling on the back of them just pulled off the colored back cover pieces, and I didn’t want to then pull by the wires. SOLVED: I found that tapping with a hammer or wrench handle on the top of those unscrewed long screws would push the harness off the bottom of fuse panel. 2) you mentioned the Odyssey Aux14 battery was what you would have preferred but couldn’t find. I did find that and bought it at first. The terminals on the Odyssey were not square/straight on 3 sides like the bent down sides of the Jeeps +/- terminal connectors need to attach flat and centered. I returned it and got Diehard Platinum and it looked completely identical in shape all over, to the Jeep original. 3) when re-assembling the fuse box, there is a satisfying snap as the lock tabs engage when pushing the top fuse panel onto the bottom tray and harnesses. So satisfying you might think you’re done and forget to actually screw back in those four long silver screws that snug up each harness. Well fyi… if that’s the case, then when you are all done, it won’t start…or didn’t for me…and a sinking feeling will set in. Luckily I walked back thru the video versus what I remembered doing and figured it out. Those screws must either seat the harnesses all the way, or not ground something, until screwed in. Again, really appreciate the video. Subscribed and will be checking out your other content!

such a helpful video man thank you. about to go on the mission of switching out my gladiators auxillary battery today.

[@wayalife]

Really happy to hear this will be helpful to you 😎

[@evopx4storm]

I've learned a lot from this guy working on my Jeep. Nice off roading vids too. 🔥

[@wayalife]

Thanks 👍

[@fornoteincyber2868]

This youtuber makes me DYI on my Wrangler JL even during the Jeep warranty period. Very good explanation !!

[@wayalife]

So happy to hear our videos are helpful to you 😎

[@huntinbob06]

Excellent video. I had no idea what a pain that auxiliary battery was, to get to. This helped immensely.

[@wayalife]

It's not exactly easy but it's not too bad. Glad we could be of help :)

[@MrTabak73]

Hey just wanted to drop a note thanking you for putting out a very simple, straightforward video to replace the Aux Battery...just completed my swap out this morning...super easy after watching your video...especially using a bungee cord to keep the stuff out of the way...Keep up the great content.

[@wayalife]

Really happy to hear our video was helpful to you.

[@bradjordan8942]

Great video - just replaced the batteries on my 2020 JT and followed step-by-step. Thanks for making such an easy to follow video - will for sure check out the rest of your stuff. Thanks!

[@wayalife]

Happy to hear our video was helpful to you 👍

[@jensimons1008]

Thank you SO much for the easy to follow video! I was able to successfully replace my daughters dead battery in her Jeep Wrangler!! Again, thank you!

[@wayalife]

Awesome! So glad to hear our video was able to help you out. 👍

[@philliplehn3600]

I didn’t know about this. We have two JLs. This guy is very helpful. He has showed me how to do suspension lift, double cardan drive shafts, track bars, control arms, caster angles now the auxiliary battery that I didn’t even know existed. My jeep has gone through all of the changes I have just mentioned from his videos. Maybe I will just change the batteries even if they make it to 4 yrs. Thanks.

[@wayalife]

Really happy to hear our videos have been so helpful to you. I should note that this is mainly a thing with the 3.6L. If you have a 2.0L or etorque, you will not have this auxiliary battery.

[@philliplehn3600]

@@wayalife Hi our jeeps are 3.6L. Went out and purchased a jump start battery. The one a purchased was quite expensive as I will get a few more cranks out of it if needed. Maybe one day it will save us. Cheers

[@bradwright7862]

Thank you!! No way I would have got this done without your video. 80 min for me.

[@wayalife]

Glad it helped!

[@vincenzomilitello9947]

Any issues with reconnecting the fuse box. I keep reading that it is "dangerous" and you should do it from under the car, but to me it doesn't make sense at all

[@wayalife]

@@vincenzomilitello9947 I would never pretend to know as much or more than people who'll tell you something is 'dangerous', even though they have zero personal experience doing it but if you read through the 1500 comments, I don't think you'll find a single person who's used this video to have experienced a problem. Certainly, if I did, you'd know about it in this video but then, that just my personal experience.

[@markmclth1]

You should be on TV!!! So good, so interesting, very good at explaining the details. Also love your pup! That was too funny!

[@wayalife]

LOL - truly flattered that you would say as much. Thank you.

[@victorchael580]

Your videos are the best. Very complete and easy to follow!

Glad you like them!

Thank you Eddie for another amazing video!! It saved me a lot of time in replacing the auxiliary battery in our 2018 Jeep JL Wrangler Sport S. You rock!!

[@wayalife]

Awesome! Happy to hear we were able to help out with our video.

[@mousemx1534]

Thank you! I used this video to change out both batteries on my daughters 2018 JL. You saved me a ton of time 🙏

[@wayalife]

Glad it helped 👍

[@robertg9514]

Great information! I read about a second battery in my manual (eco- diesel) while browsing, didn’t read entire paragraph. Looked for it under the hood and thought it strange there wasn’t 2 batteries. Now I know, thank you for the great video!

[@wayalife]

Glad it was helpful!

[@terrystotzheim9719]

Great video Eddie! I don't own a Jeep, but I like watching you work!!!!!! LOL! Thanks for the Ripley clip! Cute!

Why thank you. So glad you enjoyed it :)

Completed my Jeep Auxiliary Battery Replacement, "2020 Rubicon Unlimited" thank you so much for your video. Very Helpful. 😊

[@wayalife]

Awesome! Glad it helped 👍

[@willrouse2351]

Outstanding! Had eerily similar electrical issues going on. Thought it was the main battery. Didn't know about the aux battery. Cost a pretty penny at the dealer. Dealer mechanic explained the same thing. Aux battery failure can cause mayhem on your panels and more. Thank you for the video. Now I know what to do in the future and can save the cost at the dealer!

[@wayalife]

Glad to hear our video will be of help to you in the future.

[@OldManHistory]

I’ve sent my JLU to the shop twice over this, but with your video I will now save a ton of money. Please tell your friend at FSA that the sales team should do a daily Three Stooges slap of the engineering managers at the start of every work day.

[@wayalife]

LOL - Glad to hear our video will be helpful to you and in the defense of my friends at Jeep, they just do what they're told to do.

[@chriscon8463]

Well, I changed my aux battery, got it all back together, and everything works correctly! Thank you very much for doing this video!
