Jeep Grand Cherokee Battery Replacement - 2011-2022

[@carspec-therighteyebeforey77]

Thanks for this video. For anyone watching, BEFORE YOU TAKE THE BATTERY TERMINALS OFF, move the seat all of the way to the front AND all of the way up. The battery will slide right out without you having to twist it to the side.😊

[@LJsGarage]

Great tip!

[@jimakaracerx]

Yes, but not if you have base model Laredo with manual seats. Just slide all the way fwd, and hope for the best.

[@awsompieface]

I’m working on one but this bar is in the way w the seat all the way up n the battery on its side

[@skuzzlebutt8825]

thanks for the tip

[@striker7332]

Great video. I will add once the power is reconnected it will likely trigger the SGM (security gateway monitor) in the vehicle thus losing many functions like backup camera, temperature controls, passenger heated seats, and Uconnect will lose half the features. I’m called Uconnect, they were clueless. The solution is patience. Everything came back within a few hours good as it was. Might take longer for yours, but from what I’ve researched it’s extremely common.

[@LJsGarage]

Thanks for the added info!

[@gregschroeder1128]

Great video, unless you have a 2018 Grand Cherokee, because it is not this straightforward. You have to remove the auxiliary battery first, to even get to the bracket, and there are two places to remove the breather tube, as opposed to one. You have to remove the bracket, before you remove the positive cable, as the battery is so far forward, you cannot get to the nuts on the terminal cable, as they are under the lip of the battery compartment. The good thing about this, is once you get the bracket out, you can slide the battery back to expose the positive terminal, and then move the seat all the way back, and remove the positive cable for the front. Hope this helps if you have a 2018 Grand Cherokee.

[@ivanbarros4683]

Thank you for this! I have a 2017 and this helped me immensely!! Much appreciated

[@LJsGarage]

Good added info!

[@CrackerBarrel55]

Yea I was wondering why my battery looked extra...long? Thanks.

[@EvilB0oBerry69]

If you wanna make it easier the youcan get to the positive cable VERY easy by sliding the sea back and coming in from the front seat, it puts you directly over the top of the post with no obstructions. Then slide the seat forward again and get the battery out from the rear.

[@LJsGarage]

Thanks good tip!

[@janetchirrick1698]

Why did they put battery under the seat ? Because they hate ppl?

[@LJsGarage]

Haha battle between engineers and mechanics

[@genemoorman3065]

They put the battery under the seat because Jeep sucks. My wife has a 2016 Cherokee and it will be our last. P,OS. @@LJsGarage

[@mattp422]

So 3 days ago, my 2022 Grand Cherokee wouldn’t start and I had to have it towed to the dealer. BTW, you can’t shift out of park when the engine isn’t running, so you have to locate the secret manual transmission override that will put your Jeep in neutral (hint: it’s not in the user manual, but you can find a YT video describing the process). Anyway, the main battery was fine, but the auxiliary battery failed. After it was replaced, good as new. I was confused because my understanding was the auxiliary battery was just used for the start-stop function and was not involved with the starter. So, apparently this is true…except the auxiliary battery has one other function: powering many of the relays that have to be triggered to inform the Jeep’s computer it’s safe to start the engine. No power to these relays, no engine start. Again, not in the user’s manual. Actually, the Jeep Grand Cherokee user manual doesn’t even mention the batteries, what they do or where they’re located. There’s also not one word in the manual about jumping a Jeep with a dead battery. Apparently, you connect your jumper cable to the positive (+) post under the hood on the passenger’s side. So, here’s a question: if your Grand Cherokee won’t start due to a dead auxiliary battery, will jumping the Jeep via the post supply power to the auxiliary battery, the main battery only or both? It would actually be great if you could make a video about this. Thanks.

[@walter3143]

great video, just want to add that I will need to keep looking to figure out what to do with my 2nd battery, maybe you want to do an update one day! you the man. Thank you for this much :)

[@LJsGarage]

Thanks! and that aux battery isnt too bad once you get to it

[@WilliamTasche]

Its a lot faster to just remove the seat, just four clips that cover the bolts, remove bolts, move seat forward now you have access to batteries!

[@LJsGarage]

If that works for you def a reasonable method!

[@chrisberardi2304]

Very useful video. Short, to the point, got the tools needed. Thank you.

[@LJsGarage]

You're welcome!

[@ryrysmiles]

Can you explain why you don’t have the start stop battery? You took it out so you don’t have to deal with turning it off on the dash?…Does removing the battery take away the auto start stop warning light? Do you know the fuse for that light to disable?

[@LJsGarage]

I have a 14 before the stop start

[@XMattingly]

This isn’t “every” battery for this generation. 2016’s, and probably every year earlier has a regular sized and an auxiliary battery instead of a super long one.

[@LJsGarage]

Thats true thanks!

[@guynoir4733]

All have two if it has auto start stop but most don't like this feature and disconnect anyway .

[@happytrails151]

I get keeping the battery there if it would be crowded under the hood but it could have been at least a little further back so it comes out a little easier

[@LJsGarage]

Right lol

[@MrBowmanmt]

Great video but I do have to ask the main battery not the auxiliary where exactly are they located. Passenger seat or driver's seat underneath

[@LJsGarage]

The aux battery should be under the passenger if you had the stop start and all that

[@doctordeath4639]

Thanks for the vid it helped. But battery wasn’t dead lol. When loosened neg term got power. Think water was cause a short of something. Left sunroof open couple days ago and rained. I had power though for couple days tell a short or something and everything was dead. Only thing that wrked was power seats I wonder if that because you need to move seat to get to battery.

[@LJsGarage]

Oh man 😬

[@Aquinov]

Great, great video, straight forward to the situation, no crap or trash talk

[@LJsGarage]

Thanks my friend!

[@paulbutler6005]

Find that big red cap on your positive there is a little plug that will break off and it goes on the opposite side of the battery from your vent tube there are two holes in the battery you're only going to use one for the vent tube the other one you need to plug it and that plug is on that big red cap on the corner

[@LJsGarage]

Thanks thanks

[@leebooker6138]

Appreciate it brother.

[@LJsGarage]

Anytime!

[@WE-R-EVERYWHERE]

I have a 2019, the auxiliary battery is down there as well. After changing the main battery I went to start the truck and there is no power anywhere. Been researching for the last couple hours with no luck.

[@LJsGarage]

Good luck I'm not sure what that could be

[@darickymeister]

You could also go from the h8 battery to h9 by asking the dealer to sell you a different bolt down plate (narrower)..the one police vehicles use.... my jeep is a 2014 GC...ecodiesel.

[@LJsGarage]

Absolutely right

[@LockeLynx]

I ended up unscrewing the bolts that holds the chair down, folded it up and moved it back so that way i had more room to work

[@LJsGarage]

Nice!

[@sjt1622]

If you push seat all the way back front bracket is easy to get to

[@LJsGarage]

Good to know for sure!

[@davidsturtz1731]

what is the function of the black piece with the plug in terminals on the ground terminal mine broke off

[@LJsGarage]

I believe you are talking about the battery sensor.

[@djcichlid7746]

Or is he talking about that vent plug. I wondered what that is for also

[@Velo1010]

@@djcichlid7746that’s to vent gases from the battery to the outside. Since the battery is inside the passenger compartment they need this so any gases that come from inside the battery don’t build up inside the Jeep.

[@lou704]

I removed the 4 bolts holding the seat to the floor. 15 minute job, in and out.

[@LJsGarage]

That works too!

[@TheAussieRepairGuy]

Appreciate the info here, I used this as a reference for my own video, and I have linked this vidoe in the description of mine.

Thanks my friend!

[@DanielGomez-kk1bn]

Such a great help!! Thanks for the video!!

[@LJsGarage]

You're so welcome!

[@Peter-xtreme]

Thanks for the video - I have the battery bracket out, vent tube disconnected, negative terminal off, but I can't seem to get the wire disconnected from the negative terminal @ 3:10 mark, does it just pull off or does it have a release, I don't want to break anything.

[@LJsGarage]

Np! it should loosen with the nut and then slide ride off

[@vipergg9159]

Can you still get the battery out if you have manual seats that do not tilt ? Mine has 2 batteries in there which makes it real fun . I have seen a couple of vids that say to remove the 4 seat bolts and tilt it "backwards" .

[@LJsGarage]

Yeah you can they should slide and raise up high

[@JustinDixon-fy2cz]

Great video, saved me guessing what sockets etc... and i wore gloves so i didnt do my knuckels lol

[@LJsGarage]

Glad I could help!

[@KfromtheBAY]

How does the plastic cover come off, do you need to pry it, is there a release tab or button?

[@LJsGarage]

Sorry for the late response I just pulled them off

[@CrackerBarrel55]

Pull the hell out of it is what I did. And busted my knuckles on the seat 😀

[@elpiton5392]

Somehow my vent tube broke off . Does that come with the battery or it’s part of the vehicle

[@LJsGarage]

Part of the vehicle :/

[@greggmax3551]

I disconnected the battery for long term storage but the interior and exterior lights still come on and the electric seat still works, how is this possible?

[@LJsGarage]

If you have one battery then something may be touching somewhere that is odd

[@mattp422]

Was this the main or auxiliary battery?

[@LJsGarage]

Main

[@eudofia]

There is so much space in the engine compartment and it makes me wonder: But why put the battery under the seat?

[@LJsGarage]

Lol longevity they say

[@eudofia]

@@LJsGarage Well, my Jeep battery has lasted for four years and 61K miles. So, maybe they have a point.

[@theandrewheuss]

Did you have a H7 or H8 battery? Looking for my jeep and can’t find out which I should use

[@LJsGarage]

H7 is what I went with but you can bump up to an H8 if you want more CCA's

[@ninjasuper8]

Thank you so much sir! Lifesaver❤

[@LJsGarage]

Glad it helped! 🙏🏿

[@ashleeweary1269]

So because there are two battery's how do you know which one is dead or do they both die at the same time so do I need to replace both?

[@cmcgsr3243]

Where's the two batteries? It's only one I know of it's just a really big battery

[@LJsGarage]

Usually the secondary is for emergency systems and stop start and all that so you'll usually be able to tell

[@PiscesQueen8108]

Are there any pointers on removing the battery when the truck is fully dead? At this point, this truck is trash. I have fuel leaking from under the passenger side.

[@LJsGarage]

Fuel leak is a mess :/ if you have power seats get a jumper pack it only needs a few volts to get it to move the seat

[@PiscesQueen8108]

@@LJsGarage thank you for replying! I will definitely look into that.

[@cmcgsr3243]

So you didnt need a memory saver before changing the battery?

Everything was good to go I didn't need one

How long was your battery unplugged for bro? Im just wondering if i shoukd buy a memory saver

Yea my battery dont look like this... its like extra long.. it takes up the whole... hole. Looks like i gotta take the seat out 🙄

haha right good point

Thank you sir. Job complete.

[@titaniumgreen5367]

Maybe they will start putting batteries inside the trap door in the oil pan

[@LJsGarage]

hahah I sure hope not for our sake

[@jordanpostle8641]

What if our vent plug accidentally breaks.

[@LJsGarage]

As long as it's not exposed to crazy high temps not much it'll just decrease the life of the battery. By how much I'm not sure.

[@joharris8368]

If the battery is dead the seat will not move. What to do?

[@samshirley5482]

Attach jumper cables to a new battery and connect to the jump port under the hood. It will provide power to the electronics and you'll be able to move the seat.

[@LJsGarage]

Second the jumper cables, thanks

[@KfromtheBAY]

Mine has 2 batteries, a little battery, and then the bigger battery

[@LJsGarage]

yeah the auxiliary is the smaller for stop start and a couple little things

Seat all the way slid forward, AND seat raised to maximum height, seat back tilted all the way forward. Raising the seat gives you TONS more room to work with. 🤔🫡🤗
