All this talk about batteries!

[Essential Retiree]

First, I am not a tech. I'm an old guy. I've had lots if Jeeps in my time and have loved them all. IMO, this aux battery junk, ESS stuff is a bunch of crap. I've been reading a lot of stuff how to delete, bypass, remove etc. the aux battery.

That said, my biggest complaint about the dual battery system is the location of the aux battery. If you're going to run a dual battery system, at least make them easily accessible! So that a regular Joe can swap them out when they do go bad. (I know, I know, they placed the aux battery where it's at so you'd have to take it to the dealer)

Anyway, I'm having that doggone aux battery removed and installing a Tazer. The wife got stranded this past weekend and I'm sure everyone knows how that went! LOL!
Anyway, it's crazy stuff like this that makes me wish I had my old Scrambler or my old 1970 CJ-5 back. DGMW, I love the Gladiator but it's a Jeep! It doesn't need all this over engineering crap!

Okay....I feel better now....thanks for indulging me in my frustration.

Feel your pain. Just had both batteries replaced two weeks ago.

This is all to please our government overlords that are enforcing these new "climate" regulations on automakers. They have overcomplicated things to the point the vehicles computer gets easily confused and can go haywire. I've seen countless horror stories involving this new start/stop system where vehicles are dying while driving on the highway, leaving people stranded at intersections, and causing fires. But hey! If we dont do this the earth will burn in 4 years so i guess the pros outweigh the cons. (sarcasm)

I'm an old guy too, had more hot rods, sports cars and Jeeps than I can remember. I agree with you on the aux battery. Only a techy with no real world experience actually modding and using Jeeps would put that battery where they did. Batteries are an essential item and as such need to be accessible without disassembling half the engine compartment to do so. There are so many Jeeps running two batteries today to power winches, etc, putting that baby battery where they did make's no sense to me. As expensive as JL's and JT's have gotten, why not just design and install two large batteries and do us all a favor? If not enough room, remote the battery to another location. Mercedes has been doing so for decades. Maybe Jeep needs to start hiring some experienced Jeepers for designers and use less CADD operators. Okay, now I feel better too.

I removed the aux battery soon after purchase...leaves a lot of folks stranded if you don't know how to bypass it WHEN not if it fails.

 

[Muddyape]

Last winter, after its second aux battery in 14 months and a complete electrical freak out in my driveway…..

….

 

[djthumper]

I just had to replace my batteries. The main battery was the one that actually went bad, but I replaced both of them.

You gas guy have it rough having to go through the wheel well or pulling the entire fuse box. Us diesel guys have the aux box right below the main battery.

Actually it's extremely simple through the right wheel opening, don't even have to remove the liner like so many people say is necessary. There's youtube videos on it and several forum members have replaced their battery in minutes via the right wheel opening. No dealer needed

They are - simply peel back the rear part of the right fender liner. It's right there.

I've seen countless horror stories involving this new start/stop system where vehicles are dying while driving on the highway, leaving people stranded at intersections, and causing fires.

Yeah, amateur fire arson sleuths getting it wrong.
ESS and aux batteries don't cause fires, and the stopping on the highway can't be related to the ESS, it's other things generally not related to ESS.
That's the problem with the internet - people blame what they don't understand (or hate) and are generally incorrect.
There's no fires caused by this, stopping on the highway is a very different situation.
ESS is not related to either. In fact, ESS is non-functional when there are issues with other parts of the vehicle.
ESS isn't even in play while you are driving it so it can't possibly cause a stall or a fire.
It's just plain IMPOSSIBLE. But hey, the hate is so big - you'll never be able to show the facts to 'em, they are already convinced that's what is doing it.

I'd love for anyone to prove electrically how ESS can cause a fire or cause a stall while driving.
Prove it does or can.
I can prove it won't.......... but few would understand the explanation.

Leaves folks stranded who don't know how to properly jump a vehicle. Generally a bypass isn't needed. But hey, the internet is always right - things get repeated over and over, and take on a life of their own. The internet magnifies and amplifies the troubles of a few - and some of those few just are too macho to admit they didn't jump it right or weren't patient.

Took the words out of my mouth. Every time I have one of these problems I disabled it for ever. The mirror cheat light came on once telling me there was a car there. I deleted it. The truck tried to brake for me. I deleted it. I was filling the DEF every time I turned around. I deleted it. That goes for the rest of the exhaust bull shit. And finally it gets me to the Battery bull shit. Well let's just say the start stop function is for people with pointy shoes. Delete that shit before it's too late. What ever that means.

I cannot speak to the fires but the stalling at intersections is 100% directly related to the ESS. It literally shuts your vehicle off at the intersection and then will not start it back up leaving you in a dangerous and overall bad situation (it has happened to me). I know you will say its a connection issue or starter issue or battery issue but ALL of that has been over complicated to please this ESS. Adding a second battery is just dumb. I doubt it saves that much gas anyways. Or reduces CO2 at a meaningful level. These batteries last at best a of couple years and then get improperly disposed of 90% of the time. Overall doing more harm to the environment than good. Just like all the other failed "green" ideas. As far as stalling while driving it seems to be related to the now over complicated electrical system. I would love for to hear why you think the stalling has nothing to do with the electrical system??

Jumping your vehicle off at a stoplight at a major intersection during 5 O Clock traffic isnt ideal......

Is there a way to add a full size battery in place of teh small aux battery?

If your question is asking can you put a bigger battery in where the aux. goes, no you cannot. The compartment is sized for a lawnmower size only.

Dual battery systems like the Genesis shown above is how you get two full size.

[AstroZombie]

So the aux battery is only 14aH, would it be beneficial to add something higher like 28aH or higher?
