battery

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)

Going through a bit of a pain right now. Car died the other week, got it jumped, assumed it was a battery. This is where I learned all about the dual battery systems and the power pack. Anyway, dealership says my power pack is bad and needs replaced. Good news, it’s covered under warranty...

2023 392 oem battery. Removed with 75 miles on the Jeep. $300. Los Angeles

Hi! I was parked with my 2019 wrangler unlimited off, and it would not start. My brake pedal felt stiff and when pressing the push to start it clicked once, lit up the dash but never turned over to start the engine. I got a jump and was able to get the car fully on. I drove around for ~30 mins...

My wife was parking the Jeep and this shut off before finish the parking. Tried start again and nothing. We tried start the Jeep with help of jumping start and nothing. The starter just click, I review some fuses and relay (starter, gas pump and other and they appear good. We took off the...

2018 Wrangler JL was getting a bit sluggish in starting. Wife got to work - Jeep dead, but with power. Had changed out auxiliary in November. Had main battery replaced. All systems GO including alternator test. Starts right up. She gets 10 blocks from work and “find safe place - vehicle shutting...

My Aux battery died causing the Auto start/stop to quit. It then drained my main battery. I went ahead and replaced both batteries. Once I was done my battery light was on, along with the start/stop light. It also brought up the warning of shutting off the engine. I checked all connections...

Hey 👋 I wanted to see what the forum thinks before I take the jeep to my non-mod friendly dealer and they blame it on my headlights lol. I’ve noticed that after I turn the car on, the radio theme resets (went from 5inch to 8.4 if that matters) and the car won’t really accelerate past 15mph...

My 2020 JLU instrument panel stopped working after getting gas. Just drove from Virginia to Texas. No issues on the way until now. Radio,wipers,lights,everything else works. Picture is with the vehicle on and running. No tach/speed/fuel/temp

Hi all, I have a '21 JLUR I purchased less than 6 months ago and took it to the dealer for an oil change and a couple of items I wanted to have checked out under warranty One of the rear tail lights holding moisture, and my stop/start system never engaging with the service stop/start sometimes...

Hello all, I have a 2019 JL Sport S. It wouldn't start on Sunday so I got a jump from another car and made it back to our apartment. The next morning it wouldn't start again and I got another jump to get going. I tried driving to the local dealership but it quit at a red light and jumping it...

Hey all, I’ve been camping in my jeep recently in some areas that are less frequented by others. I am worried about a plan if my Jeep’s battery happens to die overnight while camping. Is there a self sufficient way to recover Jeep batteries?

Went to start the car today and battery is dead. Voltage in cluster showed 12.9 and no dice when jumping it either. I’ve never had a battery so flat it won’t take a jump. I’ve had other late model mopar’s and the original battery has lasted way more than 3 years. Just curious if this is the...

Hi, Did a search here and didn't see any hits on this topic specifically - so here goes. Since it doesn't appear that secondary battery options for the JLURD are anywhere on the horizon i need to dial in my "poor mans" 2nd battery setup for the next trip. That setup is: OEM 12v plug in...

I just bought my first Wrangler in July. 2018 JL Sahara. The Start/Stop function wasn’t working but I read that if the A/C was on it didn’t work so I really worried about it. A few days ago it was finally cool enough to not run the A/C and turn Start/Stop Stop still wasn’t working. I scrolled...

I have a 2022 Wrangler Unlimited Sahara 4XE and today I tried to start it and it was dead dead dead. Called roadside assistance out to the house, assuming it may be a dead battery (even though I've only had it 2 weeks), but when he tried to jump it, it kicked over, he said the battery was...

Newbie - Q's about battery + aux battery

Hi all, I apologize if this is the incorrect thread. I mostly lurk but don't interact much! This weekend my 2019 Unlimited Sahara died on me. Had to jump it and drive 3 hours home (I was out of town, conveniently). Had no issues on the drive home, but it was running the whole time. Jeep was...

I recently noticed that my Wrangler JLU Rubicon (2018 model) dash display indicated that the voltage with the engine running was around 12.4-12.6. Normally I would think this would be around 14+ volts, especially at highway speeds. I have a newish (1.5 years old) Optima yellow top and same age...

Did a search on this, and see lots of discussion on battery replacements for the diesels - but none on implementing a true dual battery system as has been available on the JKUR forever (Genesis, MORE, etc.). I have been waiting for Genesis to get theirs out, but spoke to them yesterday and...
