battery

My Dash is reading 12.7 Battery Voltage. That seams too low for me and I’m starting to suspect a weak alternator. I recently replaced my Fuse Array because it blew, I checked the alternator at the output stud and I was reading 14V. I did a just drive and everything felt good and I was at a...

Hi (Wrangler jl unl rubi 2.0t ) I have a problem with the charging cycle , battery light on the dash , 2 batteries was changed 6 months ago (agm) The alternator is charging ( 13.6-14.2) I think its ibs sensor , and i cant find the oem part , so i’am thinking about ordering aftermarket from...

Yesterday, I replaced both batteries (yes, I did keep the aux battery in the loop, for now) because the aux battery had gone down enough to finally cause the main battery to wear down to the point where it didnt start the Jeep. I changed to an Interstate H7 battery from Costco and got a Diehard...

Hey guys, I’m pretty new to the jeep and am extra dumb when it comes to anything electrical. What I’m wanting is to add a permanent pig tail to the exterior (or even interior) that I can hook jumper cables to or a air compressor to without having to mess around with lifting the hood and trying...

Watched a LOT of videos and threads here - goal is to simply remove F42 Fuse, disconnet the Negative from the AUX. Well, simple I though and today I went outside to do this after finding my main battery is constantly draining. I am pretty sure its the AUX going bad. Anyway, I opened my Fuse Box...

Hi, I recently purchased a 2020 Jeep Wrangler Sahara JL Hybrid (eTorque) with only one issue - CHECK ENGINE. Computer diagnostics revealed the following problems: 1. U003700 - HCP (Hybrid control processor) 2. U003700 - BPCM (Battery Pack Control Module) 3. B223B00 - Radio (Vehicle...

***UPDATE*** Here goes my write-up with a couple notes upfront: The process to add an aftermarket amp(s) and speakers to MY24+ vehicles is largely the same as outlined in this thread by Sting_NC_USA I do recommend upgrading your battery. I fully removed my seats for the install, it simply made...

What grounding connections in the engine bay do you all use when jumping your Jeep JLU or using a battery charger (such as the NOCO Genius series)? The Jeep manual states to connect the negative clamp to "a good engine ground" instead of the negative battery terminal. NOCO Genius instructions...

Hi, Does anyone know what the specific threshold/trigger is the Aux switches unavailable/battery charging message? Dealer is telling me battery is testing fine so they will not replace it at this time. Similarly, is there a threshold the dealerships use to deem the battery good/bad? Also not...

If I am looking to replace my aux battery, do I only need to disconnect the negative from the main before I pull the aux? Or do I need to take off both positive and negative from the main first?

Hey guys! I know the JL are known for their aux battery killing their main battery. Has anyone had any luck with getting this issues covered? Same thing happened to my mom’s last year. I’m literally a month past the warranty period . I wonder if it would just be cheaper to get a new battery at...

Hi! I’ve been dealing with a problem with my Wrangler 3.6 for a week now. I replaced the idler pulleys, and to get to them, I had to remove the alternator. First, I disconnected the main battery, then the black cable from the alternator, and continued with the work. After reconnecting all the...

My 2018 JLUR 3.6 with 30k miles starts fine with ignition push button start. But when I use remote start it acts like dead battery either clicking or cranks slow for a second and stops. If I drive for awhile remote start works but after sitting overnight same issue. Batteries are original, Jeep...

Howdy y'all. Somber day today, we woke up to an email from our RV storage place saying they logged an "incident of vandalism." They left the hood open and tonneau cover unfolded/warped. One of the pictures was of the battery area and it looks like they angle grinded, bolt-cuttered, or plierd off...

My 2021 wrangler 4xe just got diagnosed with battery pack heater control fault, has this happened to anyone else? And if so what is the cost to fix this?

Hey Y’all, About 4 days ago I went out to start up my jeep and it wouldn’t turn over, pretty typical dead battery symptoms. Hooked up jumper cables got it charged back up and started. Left it running to see if the batteries were holding voltage, started out at 13.4v-13.9v and within about a...

So, spent a few months reading a lot of posts here and doing some research on the side. I will post my findings. Hopefully it will help others in same situation. I believe my factory-installed AGM battery is likely a Group 48/H6 size with a 75Ah rating. While 75Ah isn’t tiny, it may not be...

I apologize if this has been posted already, I was unable to find anything on the Internet about it. While driving my 2019 JLUR I would hear what sounded like a cricket chirp 3 times randomly. I had friends and family try to help me find it, but it was so random and quick, it was impossible...

Hello fellow Jeepers! Today, let's delve into the discussion about what makes a jump starter an ideal companion for our off-road adventures. A reliable jump starter is essential for tackling the unexpected battery woes that can arise during our Jeep trips. Share your thoughts and opinions on...

Sorry, I'm bouncing back and forth between answers on this. I just want to get people's experiences on what they typically see. When using a 30L-50L 12v fridge and an AGM battery (for example - Odyssey 94R-H7), how long can you run it before the battery gets dangerously low? (Lower than 11v)
