Replaced Main Battery Yesterday

[Jeeperjamie]

I find it hard to believe that your stop start was not working without the battery charging message on the stop start page. Unless, like you said, you just didn't notice it. If it says stop start ready, it should work. Anything else displayed is why the stop start will not work. Battery charging message displayed for an extended period means exactly that. So you can hope the battery will charge with normal driving, you can charge the batteries yourself and reset the IBS. Or just replace your batteries.

I ran into an old friend that had a JT. After talking for a while I asked her out of curiosity if her stop start was working. She stated that she doesn't like it and turns it off. I asked her to try it. It didn't work. She didn't even know about the stop start menu page. Battery charging was the message. The dealer took care of it, she told me without any more details.

I rarely if at all scroll through my pages on the dash. I have it on the gas mileage and then up for the tire pressure and that's it. I don't look around in it and absolutely it never displayed a warning message for almost 2 months. If there was message there I didn't see it or didn't bother to scroll to it but I will say after I had to jump the jeep to get it crank 3 or 4 weeks later a message displayed without me having to scroll so not sure either way. My point was mine went with a bad battery for probably right at 4 months before I realized it needed to be changed so I was just saying maybe the person didn't have the ESS disabled and just maybe it had a bad battery.

I would of asked about how it got disabled because mine didn't work for about 2-1/2 months and I had nothing happening on the dash. Honestly I didn't even realize that it wasn't working until my wife said so thing about it. Then one day I went out to go to work and it's was dead. I charged it up and got it crank. Went on to work and had no warning signs on the dash. I drove it for another 3 or 4 weeks and then one day I had aux not charging warning sign or something on the dash. Took it auto zone who told me the aux battery was bad. Went to dealership to get them to replace it and they hooked it up to their machine and said the main battery was bad and the aux was good. I had the main replaced and haven't had anymore issues. That was 30,000 miles ago. My aux has almost 85,000 miles on it.

Just saying maybe the previous owner was rocking a bad main battery maybe. I went a 4-1/2 months riding with a main going bad.

I am now thinking maybe it was on the way out when I bought it too. Same thing my shop found; main battery bad & aux battery was good.

I'm the same way. I rarely scroll through the pages either with the exception of mpg. I set my TPMS sensor threshold down to 30psi with JScan so, unless I get a warning, I don't look at that either

Exactly! I wil turn on the stop start page just to see if It says ready shortly after warm-up. I don't care much about using it but I now check it often. I am still on the original batteries. I came here just about a year ago looking into ess. I have managed to kick the can this long by charging both batteries and resetting the ibs. I also put a battery tender on it when I park it for a few days. My stop start will work right after warm-up. I see that as a sign of battery health. A bad battery will take more time to recover after an initial cold start in the morning.

If I see Stop Start Ready shortly after or immediately after warm-up, I select a different page on the menu.

I actually checked mine this morning at various times on the way to work. Every time it said start stop wasn't available, cabin cooling or heating. Granted it's 18 degrees this morning. I shut the heater off for a bit after about 15 minutes of traveling and was getting the same display.

That was your Gladiator telling you to turn the heater back on. ?

I do wonder if they truly take the time to separate them properly and test them both independently, or just test it at the main, the main fails, they replace the main, and working together the fresh new main carries the load and passes the test.

But when my wife's 21JL went in, they specifically said both batteries failed and they replaced both, so, who knows.

First thing I've been doing is flipping on the heated seats and steering wheel whenever I jump in. I'm sure it was the original battery. I was at 41k miles.

If my temp read -17 I'd he heading SouthEast too! ? Sorry couldn't resist, we were in a deep freeze for > week too in St. Louis.

Fortunately, it's warming back up this week. Going to be in the mid-high 30s!

Is it worth the $$$$ to get the Odyssey ones?

That's a decision only you can make. The Odyssey owners will tell you it is. I went the less expensive route and chose ACDelco from Amazon.

I've certainly got no idea. I have perfectly functional OEM Aux and Main..within 3/36 warranty...and I'm changing them out of fear because of my upcoming trip.

I'll report if the Odyssey are shit.

 

[Lost1wing]

I bought the Odyssey batteries in stock at Autozone 3 miles from my house...so any warranty will be easy. That said.. 3 year warranty? Odyssey used to be 5. We will see. I have a ctek 7002 I'll periodically maintain it with. It has a special Odyssey setting. AGMs are a pain in the ass. Maintaining these isn't about amperage, it's about float voltage.. NOCO is NO GO as those don't do float.

Measured them both.... 12.8. Ahhhh....relaxing. lol

This is the NOCO that I have just started using...
