The battery stays on status charging and while in that status that feature is not available. My Pacifica is already a year old so my question is, is it cheaper to get a new one at the dealer or Pepboys or any other auto store?

I have something simlar too. I fail to understand why charging takes so long. Is this a function of temperature and the system is conservatively managing the battery? Is the battery gradually failing to take a charge. Sometimes the charging note stays up long after the engine is warmed up and other times Start/Stop works immediately after warmup. I do not get it.

Isn't the battery covered under the 36 mo /36,000 mile factory warranty (or have you exceeded the miles)?
The OEM 2 year 12V battery in my van was recently replaced free of charge by the dealer under the 36 mo /36,000 mile warranty. I don't have stop/start.
Free at the dealer is cheaper.:smile2:

it's one year old a 13000 miles, i was under the impression that batteries are covered for one year.

My 2018 operates in a similarly odd fashion. I recently left it parked for 21ish days while traveling. Started up no problem when I returned home, but as one would expect ESS was charging. I live in a small town, the longest it takes to drive anywhere is about 10 minutes. Running around town for a week after returning, the ESS never came back. A 90 minute drive to Austin and back revived it - but only for a day or two. Then back to charging. Here’s where it gets weird. Drove 4 hours to Houston - still charging. Drove 4 hours back - still charging. Home for an hour, go out to dinner - it works!

Not my biggest concern. Given where I live, one is rarely stopped for more than 10 or 20 seconds, so the fuel savings are negligible. I think there is some type of bug in the software or the data from the battery monitor is faulty.

I like to troll the guys over in the Honda Odyssey forum. Theirs is just as flaky, it eventually never shuts down unless you go through a weird reset procedure. I’m guessing most people don’t notice or don’t care.

You're probably a nice person, so I suspect you "lurk", not "troll" at the Odyssey forum.

Trolls are the a-ho**s of the on-line world. They post stuff to pick fights and rile other posters.

Several years ago I read about a study that determined that for every poster on a typical forum, there are about 15 lurkers who glean the information they want, and leave. Those of us who post here have influence far beyond the responders we know about.

You are absolutely correct, but regardless it’s more fun to call yourself a troll. If nothing else I like the way the word rolls off the tongue. I actually post over there on occasion, mostly to correct mistaken information when folks are comparing the various minivan options or to point out to folks they can get feature combinations in the Chrysler that are not offered by Honda (e.g. leather seats without a sunroof). Most folks appreciate the facts and data, though there are some religious zealots over there as well.

I can't find a better post quickly, but this one shows the items that are 12 mo/12,000 miles and the battery wasn't listed so it should be 36 mo/36,000 miles. This was for the 2017 Pacifica.

"Per page 6 of a 2017 Pacifica's warranty manual:
"F. When It Ends
The Basic Limited Warranty lasts for 36 months from the date it begins or for 36,000 miles on the odometer, whichever occurs first. But the following items are covered only for 12 months or for 12,000 miles on the odometer, whichever occurs first:

• brakes (rotors, pads, linings, and drums);
• wiper blades;
• clutch discs or modular clutch assembly (as equipped);
• windshield and rear window; and
• wheel alignment and wheel balancing"

Check your warranty booklet, battery, or ask the dealer.
You can get warranty info for a 2018 gas Pacifica at the following website, but it looks similar to the 2017.

So to get back to the original point, how does the OP know it's a failed ESS battery? Perhaps I missed it, but has a battery been load tested?
Because it stays in "charging" for ever. To me it's a sign that the battery is not retaining charge any more.

Assuming that logic is accurate, how do you know which battery is not holding a charge?

My ESS battery failed last spring, and I got an error message and a system disabled warning. I would load test both batteries before changing any parts, or perhaps wait until you see an error message or a trouble code.

Confirmed, the battery is under the 36 month warranty.

Very simple, in the dashboard I'm getting the message when I go to the stop-start page saying that the system is not available because the battery is charging and it has been in this way for long long time. Secondly, I have an adapter from 12 to 5 in my cigarette port or whatever is called that monitor the battery voltage of the big battery, it should be normally 14.2 ~ 14.4 volts and is holding that voltage. In another hand, if that was the battery with issues I would not be driving the car.

I called the dealer and they will check the battery. According to the service lady that was talking to me, the process to check the battery last an hour and a half because it's a computer test that takes that long. I'm sure that if it was not covered by the warranty the whole process would have lasted just the time to replace the battery if they had it in stock. ;-) You know what I mean.

Sounds good, I'm curious to know how this turns out.

Mine has been doing similar, when I brought it to the dealer I was told that is likely because of the cold weather. I haven't seen my van in almost 2 weeks, hopefully they will fix the alternator today. I'm also having them take another look at the ESS system, but I'm wondering if a failing alternator is what caused this. I noticed it stuck on battery charging about two weeks before the alternator abruptly failed at -17°F.

I live in MN, with a 2018 gasser.
I have been in FL the last 3 weeks.
I can tell you that in FL, the ESS works works within 3 blocks after an overnight park, works at almost every stop light, most of the time.
Back in MN, it would take a 20 minute drive before ESS would activate. Especially at sub 0 F temps. Is there something wrong with my van? I doubt it. Ambient air temp seems to have a large affect on ESS operation.

I live in South Florida so ESS should work all time. There our lowest temp here is 40 F and it happens 2 or 3 teams a year to go back to +75F.

Agree. The only bad thing is that during the week I only drive 8 miles to work and back. But during almost a whole year it was working fine.

They tested the small battery and the tool they used said the battery is good. But, the car says that it still charging so stop-start is unavailable. l think that I'm going to need @ChryslerCares here.

You might get some useful information by measuring the voltage on the batteries with a voltmeter after the van has been sitting for a few hours.

After a night of being at rest, I measure the voltage in the small battery and I got 12.46v. But this is without a load. I have seem batteries measuring without load 12v or more and as soon as you connect any load they die.

The voltage of the big battery with the car running is 14.1v.

One thing that the technician was telling me was that if the big battery was going bad the stop-start feature may not trigger. Go figure. I do not think that the guy knew too well the system. Other things that he told me was that they have replaced a lot of the small batteries up to the point that they went on back order at one point. He also mentioned that they tried an aftermarket battery but he did not like it because it was not fitting very well in the little compartment or place that holds the small battery.

So here I'm @ChryslerCares, to replace the batteries the instrument needs to return the code they will submit later to Chrysler to get paid for the battery replacement under warranty. And that's not happening. I have a second appointment for this saturday where they will test again both batteries. If nothing comes out wrong then they said that next step is for them to open a ticket with Mopar to get what to do next.
