BTW, ppl... I just figured... I don't have an AGM battery. They installed a regular lead-acid one.

Then you have bigger problems. There is a reason an AGM battery is used. Imo you have too much going on with the car to keep guessing about.

Well, let me clarify. There's nothing wrong w/the car (hopefully, at least not to my knowledge): it starts, it runs, it stops, it turns, it signals, it's cruise-controlling, it's warning me about $h*t I didn't even ask it to etc... It's performing all its functions.

As far as I can tell from the owner's manual it's not saying and AGM battery is a must for this vehicle. It's openly stating 'if installed' in the battery-related section. To me this means AGM is not coming standard.

So, my only question was: if I was doing something wrong (connecting it improperly etc.) w/my charger when seeing it not being able to charge (to be more specific, not being able to switch from the yellow 'still charging' mode to the green 'all done, disconnect' mode) the regular battery installed on this Tucson.

I can totally ask a service tech (when I come for the very first [hopefully] truly free service) if anything is wrong w/the battery(or I can stop by my local Advance Auto Parts store and check its health for free before that). I can also ask my dealer why an AGM battery wasn't installed at the factory.

But, I can totally wait for those questions to be asked/answered (? hopefully, yeah) later.

My only question was if you guys had any experience w/charging a battery on a new 2024 Tucson to confirm that I might have been doing something wrong.

Apologies for the confusion. I guess you might have though I had the car misbehaving (in any way/shape/form) as a reason for my question. Sorry about that.

 

[Tampa8]

Good that you have it figured out.

 

[nskmda]

Hm... No, not really. The charger still doesn't charge the battery. So, I'm still confused about why.

I would appreciate someone setting me straight. I own a 2022 Tucson limited without hybrid. Does my Tucson have a AGM battery or regular battery?

AGM.
In the Hev that battery is attached to the traction (drive) battery and is lithium ion-polymer.

You are wrong in your assumptions. 2022+ 2.5L Tucsons in the U.S. come with the more epensive AGM battery. Do you think Hyundai would do that if Lead Acid was as good in that vehicle? AGM is highly recommended for stop and go vehicles and others with alot of on going electronics like Bluelink for instance.

"It is important to note that although both EFB and AGM batteries are suitable for Stop Start systems, they are not necessarily interchangeable. EFB batteries can be replaced by AGM batteries in some applications however vehicles designed to use an AGM should only use AGM batteries.

You can use a led acid to the extent no permanent harm will likely occur but it will give less performance, at some point features that shut down on lower battery voltage will do so more often and longer, and Hyundai has several of those. And it likely will not last as long by 2 to 3 years.

My 2022 Tucson Limited (100%Gas) battery is 38 months old and starts the vehicle fine.All my trips are 20 min or more, which should allow for sufficient charging. Although , it has declined 20% or so, evidenced by the stop n go motor no longer operational. I believe I may gamble and go 4 years and then replace it as a preventative measure. Do I feel lucky? Well do you punk?🤣😅🤨

How do you know you have a lead acid battery in your Tucson? Which label does it have on it? My 2024 Tucson ICE has an AGM battery. I have searched and you can only purchase an AGM battery for a 2024 Tucson ICE. My other vehicle has an Optima Yellowtop AGM battery. I have had to recharge it and the lead acid battery in my old Ford Escape. I use this charger. It works well with both types. Did I miss it, what charger are you using?

And why I posted they all come with it for a reason...

 

[nskmda]

the stop n go motor no longer operational

I'm a worrier... If anything starts showing signs like this I [personally] would replace the battery.

Not sure if you are still looking for 'being set straight' on the battery type. As far as I know the battery type should be clearly shown on the label.
Mine (2024/gas) is old school Pb+acid... No luck having factory install an AGM.

I think if you take a picture of exactly how you are connecting your charger to the battery, it would be helpful. That would answer many questions. I would add if you are concerned with discharging your battery because of your usage, I would make sure that I always turned off the auto start/stop function that modern cars are now saddled with. If you do that, even a short drive should be enough recharge the battery.

 

[nskmda]

I think if you take a picture ...

Maybe I didn't express myself clearly enough.
I said I actually had my charger finish charging the battery.

"I would add if you are concerned with discharging your battery because of your usage, I would make sure that I always turned off the auto start/stop function that modern cars are now blessed with. If you do that, even a short drive should be enough recharge the battery. "

Ha! Fixt that for ya. And of the (many many) operating criteria required to allow the S/S to become energized and function at all, one of the most frequently mentioned and most prevalent requirements is that permission for the engine to turn off is denied if the battery is not sufficiently charged, or to the point, this "not running long enough to recharge itself" concern.

Cliffnotes: There's quite a few conditions to meet before S/S system even gets activated, any one of said conditions not being satisfied and the engine will just plain not turn off, either at a light or just stopped in traffic = (engine not to temp., AC on and not cool enough inside, too damm hot/cold outside, etc.). And there's been some "now-not-so-recent-anymore" accountings on the forum of the S/S turning off the engine but it not restarting, and those were tracked to an unrelated glitch in a different system which I recall is being treated by a TSB. But I've not read anything on here related to a battery that "wasn't re-charged enough" to restart the engine after S/S stopped it.

".... But I've not read anything on here related to a battery that "wasn't re-charged enough" to restart the engine after S/S stopped it."

Probably the #1 reason. Manual specifically singles out the battery condition and stop and go. It specifically says it may not work without an agm battery.

 

[nskmda]

It specifically says it may not work without an agm battery.

Yet it totally works for me (w/o AGM battery).

 

[Tampa8]

Yet you started a thread about a non agm battery not charging fully even on a charger and being slowly drained.

 

[nskmda]

Not sure what this relates to.
I never claimed I had AGM battery, did I?

This is what I said:

I'm mostly making short trips and the battery would be slowly being drained.

I assume you guys understood this as a statement. But I said "would be" on purpose, trying to show that this was my guess. And that I was trying to recharge the battery out of pure sense of precaution.
Looks like everybody assumed that was a statement, that I knew for sure the battery was actually being drained and I did have some issues.

I tried to make a point that was only my assumption but maybe I wasn't clear enough on it. I apologize for that. I'm not a native speaker and might not have used English grammar to the best extent possible.

Also, I didn't say the battery was or was not charged fully (specifically, by the car's charger). What I was talking about was my external battery charger behavior.

Again, I apologize for misunderstanding.

Eventually my external charger managed to get to the state of 'green light => the battery is charged'.
I'm not concerned with the charger's behavior any longer.

Also, I'm grateful to everybody who responded. I believe I'm all set for now.

Not sure how I can 'close' the thread, though.
