I changed the battery in my 2017 Jeep Grand Cherokee and now it wont go past 50 miles per hr...do I need to have a car reset? Or the battery reset?
Ya, I saw that you posted while I was asking. I'm going to wait for @Mark_ to chime in, but that's a standard, non AGM unit I think, and I don't think that's the one you need.
Sorry for the late reply. Yeah that group 65 battery is all wrong. Not sure what they're doing at Oreilly's...View attachment 212667 is this the correct specs needed?
Ok great...thank you so much for helping me outThat's the wrong battery!!! Your 2016 GC V6 calls for a group 49 AGM!!! 94R is what we have in our KL's. I didn't think they were the same. You need at least one of these.$229.95 at Batteries +. View attachment 212668
I think he did too lol cause they said they're gonna give me the correct battery for the same price I paid for the wrong oneI think the dude at O'Reilly's pulled up Cherokee, instead of Grand Cherokee!!! Please don't tell me that they also installed the wrong battery as well, I've already about lost all hope in humanity!!! LOL!!!🤔
Its definitely a 3.6L and yes they're gonna make it righySorry for the late reply. Yeah that group 65 battery is all wrong. Not sure what they're doing at Oreilly's...
Do you have the 3.6L or the V8 ?
If I'm reading this right, the 3.6L requires a group 94R AGM (just like ours in Cherokees) and the V8s require the bigger group 49 AGM.
They need to make this right. And make sure they sell you an AGM.
Mark, what's the difference between the two? They must be similar size, and space wise??? Batteries + showed that Duracell AGM in 49 for the V6, then O'Reilly, the 94R was at the top of the list??? Does that mean a 49 will work in our KL's as well???Sorry for the late reply. Yeah that group 65 battery is all wrong. Not sure what they're doing at Oreilly's...

No worries, glad we got that straightend out for you. Keep us posted on your outcome when they get the right one installed...Thank you guys so much for helping me out I truly appreciate you guys...I truly hope you all get all the blessings in the world Thank You Guys
The 49 is 1".5 longer, possible-maybe, but you'd need to do some fiddling to the tray and hold-down. I'd just prefer the X2 in the 94R. Better specs/and warranty than most...Mark, what's the difference between the two? They must be similar size, and space wise???

Ya, I'm with you on the X2. If I didn't get another "Sub Par" factory Mopar replaced under warranty after just 14 months of service just yesterday, I would absolutely be running the X2. It's going to be the next one for sure. I was just curious about the size difference to benefit the OP, with getting the one that fits the best, as it was showing both options for the GC. After this second Mopar bites the bullet, I'll run nothing but 94R X2 in my Trailhawk, way too much drama associated with just the slightest voltage irregularities on these things, and I want the biggest, baddest battery money can buy...LOL!!!😎The 49 is 1".5 longer, possible-maybe, but you'd need to do some fiddling to the tray and hold-down.

Yeah the group 49/H8 don't fit in our KL trays. Too long. Other than length, all other dimensions are equal to the 94R/H7, so is positive terminal postition.The 49 is 1".5 longer, possible-maybe, but you'd need to do some fiddling to the tray and hold-down.

Hmm. I consulted 3 auto parts fitment guides (well, 2 auto parts and Batteries Plus Bulbs) and they all pointed to a group 49 AGM for a 3.6L 2017 GC.The Grand Cherokee doesn't use the same battery as the Cherokee.
I had a 2017 JGC Limited with the 3.6L and ESS.
The OEM battery is a Lead Acid Battery, and the ESS battery is under the driver seat and its a motorcycle battery.
What is causing your issue is using the incorrect battery for the Cherokee and it not playing nice with the ESS system, throwing all kinds of things into "I don't have the inputs I'm expecting so I'm going to do nothing" routine.
You need to get the correct battery for your JGC and hook it up after leaving the cables unhooked from the battery for 10 minutes.
This should force everything to reboot and it will take care of the 50 mph problem. If it doesn't you have damaged something and need to take it to the dealer.
There are three options for the JGC powertrain on a limited. A 3.6 V6 Gas, a 3.0 V6 Diesel and a 5.7 V8.Hmm. I consulted 3 auto parts fitment guides (well, 2 auto parts and Batteries Plus Bulbs) and they all pointed to a group 49 AGM for a 3.6L 2017 GC.
Which battery did you have in yours ? O'reilly's choice for the OP, originally, was a wet group 65.
I honestly have a hard time processing how a car manufacturer can fit a wet battery under a seat, inside the cabin, with the spill hazard and gassing... I know they have vent tubes on them, but still...
Ok... well, it's even more confusing to me now. Other than the online fitment guides, this is what I saw that convinced me that ESS GCs (recent) have 2 AGMs under the passenger seat :There are three options for the JGC powertrain on a limited. A 3.6 V6 Gas, a 3.0 V6 Diesel and a 5.7 V8.
Only the 3.6L V6 has ESS. My 2017 had two batteries, one is under the hood (primary battery) and the ESS battery is under the driver seat in a well. It can't be accessed without removing the driver's seat and its a PITA to get out after that.
The ESS battery is an AGM like the one shown below. The information showing group 49 and saying its under the passenger seat are incorrect.
The primary battery is a group 94R, the information on the websites of Orileys and Autozone are incorrect.
Proof in point: Both Orileys and Autozone suggest the V8 JGC takes a group 94 and 49 battery, stating the group 49 is the ESS battery. No V8 JGC has ESS.
