MAJOR JEEP PROBLEM - How To Fix It?!

If you've ever experienced a dead battery in your Jeep, especially if its a newer Wrangler JL or Gladiator, trust us when we say that you're not alone...AND, there's a fix. It's a known problem that newer Jeeps equipped with an auxiliary battery can leave you stranded with a dead battery. And since generally the cause is the auxiliary battery itself, rather than your primary battery, jump starting the vehicle like normal doesn't always work.
So we decided to finally make a video going over the dead battery issue, what to do if you find yourself stranded with a dead battery, how to fix it by removing the auxiliary battery from your Jeep, and the ultimate fix to make sure you're never stranded with a dead battery again - an Antigravity Battery.

You probably don’t remember this, but about a year ago I was at your place, Chris and Bec were installing the rear locker on my JK and my buddy Andy was helping you with the coil overs on the Juggy. The juggy didn’t have a battery in it, but we were able to use my jump box to start it… that’s the jump box you should get. I love that thing and it’s saved more people that I can remember. Well… I guess you don’t really need it now. LOL ❤😅

[@mikemullay5622]

That stop-start feature needs to go away permanently from any vehicle. I realize I am an old fart who began driving 53 years ago but stop/start is as crazy as the 4-6-8 Cadillac engine was.

[@martinklaus2203]

I solved my aux battery issues by installing the Genesis dual battery system. Absolutely love it!! That is how all Jeeps should come from the factory.

I literally within the last 4 days began having issues with my 2020 wrangler starting via remote start and this morning actually had to jump start it. I will be replacing the main battery and will look into deleting the auxiliary battery, as the auxiliary has not worked for the last year. Great timing on the video guys, thank you.

[@ktjl7479]

HUGE THANK YOU!!!!!! I have been hunting for information on the Aux delete.

[@bolds52]

Love your channel. I had to comment here. I have been a technical trainer for several European car manufacturers. On newer vehicles the module that controls the charging rate is programed for different batteries. For example a BMW can be programed for the earlier lead acid batteries (the ones that you have to check the water level) or the later deep cycle batteries. While the batteries perform fine, they can damage the alternator. I don't have experience with changing out a deep cycle battery with a lithium Ion battery, but it could wind up damaging the alternator or the module that controls the charging system. Keep up with the great videos!

You pull fuse F42 and disconnect the aux battery lead from the main battery (the L-shaped one that sits beneath the flat one). Electrical tape the shit out of the aux lead and zip tie it out of the way. Done.

I used your suggestion and jumped it with my jump box to the auxiliary terminal and it fired right up. Guess the Stop/Start battery must be shot already. Thank You !!!!

[@1a1u0g9t4s2u]

Just 4 weeks ago I replaced the main battery in my JL. When it needs replacing I'll seriously consider the AntiGravity battery if the auto parts store does not honor the standard battery warranty. This is the third battery since 2019, so even at the higher cost for the Antigravity battery it will pay for itself if it truly lasts for 8 years. BTW, I do have a trickle charger on the new battery.

Could have hooked up your battery cables to an auxiliary power jump pack to retain your vehicles settings while swapping out your battery.

My Antigravity battery exploded after 2 weeks of use. The car was just idling. I had to file a warranty claim and am still waiting for reimbursement. It was 680cca smart version with bms which is much smaller but my truck only requires 640cca and wasn’t on their list. I hope you have better luck!

I’m not sure you showed how to exactly eliminate the aux battery. Does just removing it eliminate the special wiring to it? If it’s not there, do you need to do something special with the wiring?

You have to tie post one and two together. He said he did that but didn’t really mention that again after he said to wrap up the hot wire after you yeet the aux battery. You can also put the positive that was on the aux battery to the positive on the main battery to skip the post one and two jumper.

[@rosco1883]

I have always liked lithium batteries and have even had highly Insulated ones. I recommend them for motorcycles because most people don't ride in the freezing cold. But depending on how well they are insulated they drop power big time between 30 and 50 degrees. If temperatures get in the single digits I don't know of any lithium battery that would still start a car unless it had some kind of heating element with it like a tesla. It will be interesting to see how this battery performs this winter.

[@Seb_Semos]

One of my car doesn't like to not start for a week... that's seems to be a good fix :) Thx!

[@vegasfordguy]

No it's not a good fix. You need to address the parasitic draw and correct it. This is simply a bandaid.

Keep in mind that Lithium Batteries, ( lifepo4 too) do not like temps over 120DEG F, under the hood temps may cause issues with wheeling/crawling and heat accumulation. Likewise low temps either. They're rather temperamental temp wise.

[@randysmith5466]

When you eliminate the auxiliary battery does it automatically eliminate the stop,start feature or do you have to disable it also? Thanks.

[@MarkSpencerAZ]

Ran into the dead aux battery while on a trip in our RV flat towing our Gladiator. Of course the Aux battery is only available at dealers, so we had to plan our route through Flagstaff to visit the dealer. Delete is next! Thanks guys for this video! By the way, Lithium Iron Phosphate, LiPo4, is not like Lithium Ion, A.K.A. Lithium Cobalt used in electric cars. Much more forgiving and no danger of run away heat. LiPo4 are the thing in off shore power in the RV world today. While the up front cost is high, they actually cost much less over their life.

[@PiDsPagePrototypes]

Easier to say "Lithium Ferrous Phosphate" for those, so people don't hear "Iron" and think "Ion" And while they're great, and substantially safer, the replacement for them is already coming, Sodium based batteries, which should drop the cost significantly, as Sodium is a lot easier to source and more plentiful.

[@GoChangeYoLife]

Autozone sells the aux batteries as well.

[@buttcheezemo]

[@nocogarden]

The only drawback is the charge protection won’t allow the battery to charge in anything below 30 degrees. Keep us updated on how you tackle that challenge this winter. I may be ok in Utah. But Colorado that’s just a no go.

[@jtoyo007]

I thought of that as well but the heat from the engine once it’s running would heat it up over 32 degrees no problem

[@gman125]

Battery blanket heat wrap?

[@1sheinz]

I've had one for 2 years now here in Canada Where it gets -20c regularly in the winter. NEVER has it failed , never has it been weak. IT STARTS IN THE COLD BETTER THAN ANY OTHER BATTERY , AND IT WARMS ITS SELF as current flows thru it and allows the alternator to trickle charge even below 0 till it is warm enough to allow full charging. The heater fan and defrost run at 50% faster speeds than a lead acid battery as they get 13.4 V all the time even as it discharges, even at 20% charge it still has over 13 volts.

[@dupton8000]

Thanks for the info

[@aaronl_trains_and_planes]

Traded in my 2012 JKU Rubicon Call of Duty Jeep yesterday and got a 2022 Rubicon Gladiator. And it's a stick shift!! HAven't driven it enough to play with the auto stop/start, but I don't think that's a wise feature for my manual transmission. I love that new type of battery. But $1200 for a battery is a little pricey. But if it helps and lasts longer, and in your case you've already spent that much on new batteries, so this should take care of all your problems.

Dose a 2021 need to hook up the aux batter terminals or just tape them up? I have heard they need to be connected so that other stuff works too? Thank for all the info guy keep it up and see you out on a trail somewhere!

[@wendellaustria1962]

Check out your alternator ,it should be putting out 13.5-14.5 volts @ idle. If it’s lower than that it could kill your new battery like it did the rest. Antigravity batteries work great. Great video!

[@zd533]

This is not quite true with modern "smart" alternators like the JL and JT have. Output voltage can go as low as 12.3v or so, depending on the engine loading, battery charge, etc. I had the same battery issue within a couple of months of getting my 21 JT. The small aux battery fails typically and subsequently kills the main battery. This is not related to the alternator (unless of course the alternator is actually bad)

[@mrmgjohnson]

No... at idle you're Jeep should be sitting at 12.7 or so on a fully charged battery, as you drive, you will see the 13.5-14.5 v you are talking about.

[@angowT]

I have to disagree with your assertion about jump starting. I just bought a 2018 JL and one day it wouldn't start. I tried charging the battery ( which was a few months old) but it wouldn't hold a charge. Id only had it 3 weeks, so i called the dealer requesting a replacement battery, or to get them to locate a drain. They told me that it was the aux battery, which i didnt even know i had and to jump start it return it to them. I jumped it no problem just using the main battery terminals. The dealer told me that the main battery had been replaced but that the aux was the original, so they put a new one on. I have now disconnected it. Great vid and great channel. ( Maybe the UK version wiring is different?)

[@Krystof.Veritae]
