Replacing stock 392 battery

[Viking Jeeper]

I called the dealership. They go by 3 years or 36k miles. But the catch is I am required to bring the whole jeep in so they can generate a code to get it replaced. I can’t tow because it’s in the back of my garage at the moment. Plus it’s just crazy that they require that. But I understand that they have a procedure. Plus I already pulled the battery. I guess I’m back to my battery hunt.

Lame!

I was hoping it was covered. I am not surprised at all though, that they want to see the Jeep. I cant see them ever just swaping your battery with you.

anyone know if these batteries require “programming” the way BMW does? That’s the biggest crock of I’ve ever heard. The BMW and Mini need to be programmed when you swap the battery.

WTF. I have never heard that. Its not like I was ever planning to buy one but thats one more reason to never buy a BMW (I'm not even going to address Mini).

Haha yup. When replacing BMW batteries, they need to be programmed or idiot lights come on. Luckily, you can use a programmer at home these days.

What I mean by swap it out... is if it were to go bad in some way. Do you need to get it replaced long distance where you need to wait for something to show up from UPS or something... Or did you get them from a local shop that you can walk into and exchange. If they did agree to replace it, do they then ship the replacement to your house... things like that... so if you were at a Kroger getting some food, and you walk out to your car and its dead... what's next? Tow home, then chk the battery? regardless of if it's bad what's next... call CS and ask them to swap it out and how long would that take? if you need to drive it, it may not be a good deal if it takes a week to get a replacement.

The AG battery has a safety cutoff so if it does go past a certain voltage, it shuts off until you press the restart button. In theory, it shouldn’t leave you stranded If the battery is healthy and so is your charging system. I mean, I have AAA for a reason if a vehicle does dies on me too. In a pinch, you could replace the AG with a regular battery if it truly is dead and you need the vehicle right away.

Let me say that this battery isn’t for everyone because it is expensive and isn’t stocked at the local Autozone if you wanted to just pick a new one up. But it is an option for those who want a lighter alternative and don’t regularly drive the vehicle or have a charger on them. I just recently had to use the restart button on my E46 M3 as I didn’t drive or charge it all winter and wanted to go drive a manual over the weekend. Your mileage may vary.

Makes sense. The restart and light option is a big deal. Also my jeep sits for months at a time as well. Sadly I didn’t plug in my battery tender and here I am. I’m very heavily considering the battery. Even though I think it’s a crazy price.

For cheaper you can get a regular battery and a jump starter box. I have one in each vehicle and have started many engines with them.

I have a jumpstart box. But you make a good point. Tough call. This battery is compelling. Could be I need to just go get an Odyssey or optima and forget about it.

 

[Tank2112]

Sorry man...didn't mean to stress you over the Antigravity battery. lol...

Only thing about a jump box, which I do uses, it to make sure to keep it charged.
Weight saving does sound good. I don't know much about Antigravity batteries, just saw them in a Lite Brite jeep video.
They seem to love them, but the also pulled the engine out of a brand new 392 to have a 800hp+ Demon engine installed by AMW. So money doesn't seem to be an issue?

Yeah, well, the Mini is my daughter’s car. It was her pick.
The BMW, my pick. There’s certainly my fair share of gripes. Great drive, over engineered.
Just added a Tesla. We’ll see what nuances that brings.

 

[Viking Jeeper]

Of course any battery needs to be kept charged.

I have not done much looking into the AG battery but I have to assume it just has a battery battery maintenance system that cuts off all output once a specific low voltage is reached. The "jump start" button overrides that and allows the battery to once again provide power to start the vehicle. Not all that complicated. It too, can get run down.

Antigravity 80Ah H7/Group 94R Lithium Car Battery w/Re-Start​

This seems to be the battery LB was installing. It’s back ordered on the site.

I chatted with with a sales rep on their site today. The 60Ah and 80Ah should be back in stock any day now.

 

[ketanladd]

Get them to check if the alternator is working properly. Could also be the problem if it’s not charging the battery.

I want to think the Antigravity battery is the one to get... but with all the negative feedback it's hard to do that. The manufacture said the battery should last 4 years (with full replacement in 1-3 years) ... possibly longer. I like that its only 22 pounds (for the 80Ah). And I like the restart feature. I do not like that it seems to last as long as the other competitors (AGM Batteries) like Optima and Odyssey. Other than being light, its life is the same... but comes with restart. The AG battery is $1200, where the Optima is $360, and the Odyssey is about $350 for the performance and $400 for the extreme (assuming it fits?). if you do the math, you can get more life for the cost of one battery from any of the others. So other than having a lighter battery, or the restart... why would I want to go with AG? Still trying to decide.

Hey folks. My 2021 392 has a dead battery. I’ve tried to jump it, charge it, and it’s not taking anything. I pulled it out this morning and put it on my ctek (7002) and it’s acting like it’s charging. But I’m not so sure it’s going to work out in the end. I don’t have a way to load test, but I can take it to a parts store I guess. In my experience if the battery is low, the load test isint valid anyway.

Long story short. I k ow I’ll get some different responses. But what is the go to battery that’s an upgrade from stock? If my battery doesn’t take a charge, and I’m forced to replace… I’d like to put a battery in it that is fit for the 392.

Thoughts?

My launch edition battery died 22 months after delivery. Replaced under warranty at no cost so I’m happy for now.

Where is the negative feedback you're reading? I'd like to read it too.

I just got this from their chat window on the website:

Me: "Hello again. I am curious how your battery products compare with typical AGM batteries in useful life. Is there a difference?"

"Chad": "depends a little on the model..powersports are generally rated at about 5-6 while automotive are rated at 8+ due to the larger capacity." (in years)

ETA: I see the 15% 1-star reviews on Amazon now :-/

 

[Shortcut]

How would I know if it’s still u fee warranty? It’s a 2021

3 years or 36K miles, has your Jeep exceeded either?

The real downside is disposal when the Lithium batteries are finally used up and you have to pay someone to take it off your hands. In ten years when all the electric car batteries and these Lithium starting batteries are sitting around as hazardous material, we will be facing phase two of the environmental crisis.

If you choose an Odyssey battery make sure you read the requirements for charging it and keeping it charged.... it is not what you think.

looking this up now.

@Shortcut... They will replace my battery. I have not exceeded the time or milage. However, I would need to tow it to them. At the moment its int he back of my garage. Would be a nightmare to get it out. Plus, the cost or effort in the tow. It just seems like a good time to buy new.

Towing should be included with both your Jeep Wave and warranty benefits.
