Auxiliary Battery Delete Poll

[Badweather]

The 2 pos cables at the aux battery are already bonded, look at the photo above where the red cover is, there are 2 cables crimpted to 1 lug.

You could disconnect the 2 lugs at the PCM and bond them, that would act like convoluted N1/N3 bridge. Sponsored

I see that now, I will probably leave it alone and try to ignore my OCD urge

You aren't driving properly if you're stopped in an intersection long enough for the ess to shut off and then the yellow light causes you to accelerate quickly. If you were properly stopped outside the intersection and then stayed where you were when the light turned yellow it wouldn't be an issue.

Of course I'm driving improperly.

Time bombs have no issues either until they blow up. My take is that in about three years the aux will go bad simply because of age, but then they can be a pain. I HATE that auto off thing and the ever so slight hesitation at a light when you wanna go. My wife hates it worse than me and will turn it off the instant she gets in on the passenger side... Same when she drives it.

You can get a device for around $125 that will essentially press the dash button for you, and remember how you want it set.

I have nothing against the ESS, it seems to work fine. I always press the button after starting because I don't want it to interfere with the cabin cooling. I'm too cheap to pay for the Smart Stop/Start device.

The Aux Battery is more likely to outlast the Main Battery. The heat under the hood and not being properly charged shortens the life of the Main Battery.

I got 3.5 years from the Build Date out of the Main Battery on my first Gladiator. The Aux Battery lasted four years, and then rode around dead for another six months before I replaced it.

New 94R battery about a year old. Aux negative cable removed and taped up. Tazer ESS off. Got home after a 10 day trip and the Jeep had power, just not enough to start. Got a quick jump and all was find with alternator showing around 14.2 on the ride home. Did I miss something on the aux delete?

What makes you immediately think that? Did you test the battery? Search for parasitic draw? That’s where I’d start.

I ended up adding a solar panel and charge controller on my toolbox to charge the batteries through the trailer connector. The batteries may still die of underhood temperatures, but they damn sure wont die from not being charged enough.

Never an issue for me - by the time my foot slides from one pedal to the other, it's ready to go, no hesitation. I may be old, but after a few times racing over the years, my reaction time at the tree isn't bad at all. It goes when I tell it to go.

There's a lot more to these than that little battery. New batteries, even a year old, can fail. You may have other issues, like a bad connection at the main battery posts. Could be IBS issues - like improperly resetting it and charging the "new" battery before install, there's several things that could cause such things but people believe the incorrect notion that "it's always the aux battery".
In short - If you removed the cable - there's no way it can cause any issues.

MAYBE you need to test that "new battery", or at least charge it and reset the IBS.
Did you fully charge the new battery before installing it, and remove the IBS and let it sit for several minutes when you swapped batteries? I would guess - no.


Generally speaking to the whole web -
Just in general, and it's all over the whole internet, mostly Jeep, but other places as well.......
Seriously, honestly, half of of the issues are a general lack of understanding of electrical systems and batteries.

I didn't charge it when it was originally installed but that was a year ago. Dumb question, what is IBS? I did put the battery on my battery tender last night and it now has a full charge. Should I disconnect the battery, wait and then reconnect?

I have not deleted or bypassed the aux battery. I have installed a device that keeps the ESS system off unless I want it on, which won’t happen. Mines a used 2021, daily driver, and works great.

 

[biodiesel]

Mine is a 2023, so I don't have any bragging rights, but I bet my OE batteries last at least 6 years. Why? Because I keep them charged, maintained, and desulfated! All I have to do is plug it in!

 

[DankjeeP]

Just remember this is part of the emissions system for your car and by law the EPA can come after you if they determine you did remove or permanently disable it. Watch out in states that require vehicle inspections.

bullshit

Surgery was successful, it feels great to get all those extra wires removed and back to a traditionally 1 pos/1 neg setup.

I did the N1-N3 bridge aux delete mod and used a razor to carefully cut the electrical tape and wrapping to separate all the wires for the AUX battery. Chased the wires down to the fender where the PMC lives and disconnected them from the PCM terminals. ALL GONE!

I pulled the #42 fuse as a cherry on top to make sure the PCM is offline. I am also running a auto stop eliminator add in to remember my off setting.

Needed to replace my main battery as it was starting to go, and gave me a good opportunity for some house keeping.

As a bonus, I successfully cloned my ecoD ECU and installed the clone ECU for testing since I was into that area. And everything started up with not errors!

Here is the diagram I used posted by @Hootbro

Love it! These dummies that think making MORE batteries is a good thing need to look at Indonesia and all the other locations being RAPED of their rare earth minerals. Peace. delete this stupid thing and move on to the next dumb thing.

Energy density of oil based fuels is 13:1 vs batteries.

You might want to chill out for a second and learn what AGM batteries are actually made of.

Yep,I do also.No brainer if you garage the Jeep.Been doing this for years.
