98%, but I just charged it recently

 

Mine varies between 70 & 78%. I haven’t seen it close to 100% since I bought it in November. I have thought about putting a charger on it but it starts OK.

Do you have your ISG on all the time?

 

ISG is on all the time, but I've learned to brake without the engine stopping. I'll need to keep an eye on it since the temperature is getting much colder now. Maybe I'll hook the charger to it. I've had the car since late August.

Thanks for the replies. At least I know it's all over the place.

 

66% for me. I've only put on 850 miles since taking delivery on 12/3 so I don't drive too much.

Hopefully folks who drive more have higher percentages since it would have given the alternator more of a chance to charge the battery up.

 

For some reason I never noticed the battery icon on the app until lately.


I drove this morning and it's still at 68%. It may have always been 68%



I'm going to charge it and see what get tomorrow.

 

are you talking the vehicle battery or your phone battery charge displayed on the center console? where are you seeing this?

 

Rilles,


I'm referring to the small icon on the My Hyundai App. Image attached

I've got the battery minder so it should also work the AGM

Mine is at 68%

 

Mine has been fluctuating between 74% and 78%. Last night, when I read this thread, it was at 77%. This morning on my way to work the battery indicator came on :|. I'm at the dealership now. When I stopped, got here I checked the status with the engine running and the battery was at 66%.

1200 miles on it and already having an issue. I'd say it's better than having oil dilution on a CR-V, but I own one of those too... double whammy.

Please come back and tell us what the outcome was. Mine has never shown more than 78%, and that was after a 200 mile, 3 1/2 hour drive. Could be the App is not accurate...hopefully.

 

Well, mystery solved. A rat has been chewing on my drive belt and today when I started the car I caught it having its (last) breakfast, causing the drive belt to get stuck and the alternator to get no power. That’s $125 to remind me to park the car in the garage every night. And get some rat repellent for my other car

Question
how does Bluelink get the info? to get an accurate # shouldn't the battery under load?
Reading the voltage when it's not under load will read 12-13 VDC

 

Great question.

PCM Ernie might know

 

Trickle charged overnight. Now at work and it's at 70%
I'm going to charge every night to see how high I can get it and see what happens after that.

 

75% for me. Only had a week. As long as it starts I don't care

 

As I keep charging nightly it creeps up. It's at 79%.


It looks to me like driving it does little to nothing to improve the charge. The only reason it has increased it because it's being manually charged. I'll just keep charging until it reaches its peak which I doubt will ever be close to 100% because of the bluelink.

 

Must be careful ..... if it reaches 100% the battery will explode LOL :=)

 

Just back from a 210 mile freeway drive, half in dark and the myhyundai android app showed battery at 82% so I'm thinking no way to get 100% this way.

 

I charged mine all weekend and only got it to 82%. Then I gave up.

Now it's at 74% so who knows what the deal is.

 

Mine was at 68%, left it with a battery maintainer on it when I left and went south for a few weeks. Was up to 74% at last check. However, I could only check for 4 days and have not been able to get an update since then. I finally called Bluelink support and this is what I was told:
1. Charge between 60% and 100% is considered GOOD or OK
2. One will lose the ability to get Vehicle Status updates (via the bluelink app) if the vehicle has not been started in 4 days. That system seems to go to sleep. Sure glad my car is at home in the garage and not at an airport or something. Four days seems pretty quick to lose the ability to see vehicle status. The agent thought if the car was remotely stated, it would reset the 4 day timeout. Unfortunately, since mine is in the garage, it is probably not a good idea to start it until I get home and open the garage door (smile). I think the 4 days should be extended to at least 10 days before the Status function goes to sleep. I assume this is done to save battery, just a guess.

If I can remember, I'll post an update on my battery charge when I get home.

 

Just got my 2019 SF back from 1.5 weeks at the dealer because the Stop and Go wasn't working. They found out that when my car was manufactured the battery was charged at 78% and with Hyundai's "Smart Charging" system it will only charge the battery to the level it to the it was at when built, so when the battery reached the 78% level, the charging stopped. The only solution was to install a new one charged at 100%. The Stop and Go system (along with a bunch of other items) requires that the battery charge be at better than 80%.

 

Thanks, great information to know. This may tie directly to some of the issues posted over on the ASG thread.

 

Before they did an update to the MyHyundai app, Nov or so 2018??, not real sure of the date, however the battery voltage had always registered 100%. Shortly after this I noticed it down to 79%, then 72%, and today down to 62%. I drove it yesterday and had no issues with the car at all. I put my Battery Tender on it this morning just to be sure, and just checked it a bit ago and it shows on the Tender that it is at full charge. The app, when I just checked it now still says 62% on the battery. I called Bluelink last year when I first noticed the battery issue and they checked from their system at that time and said that it reported no issues and everything on the car checks out good. I'm guessing that someone (developer) may have changed something in the app that doesn't agree with the readings coming back to it and they just need to go back in and fix the app.

 

Just got my Santa Fe (Ultimate 2.4 FWD). My battery says 93%.

 

Well something isn't right then.


Either the app is wrong or the batteries are low on charge.
If stop and go requires at least 80% to function, then my battery must be at 80% because it's working.


So after I charged it and it read 79%, what was it really at? 102%


The blue link app is useless for this and at 30 below temperatures it would be nice to know if I am really at 64%, 44% or 84%

 

I leased a Sonata Ltd 2.0T on Feb 9th, and the battery (per my iPhone's MyHyundai's app) was 86%. It's at 83% now (3/1), and I'm going to try to get on Florida's Turnpike this weekend and get over 2000 rpm, which is almost impossible for me to where I live, even on I-95, due to traffic congestion. Even at 75 mph, the rpms are at or below 2000, and it's impossible for me to maintain that speed on I-95 for more than a few minutes.

I find it hard to believe that an app could accurately display battery status, so maybe I'm obsessing over nothing.

Nothing to worry about at all. The app has shown anywhere from a 61% to 78% charge for me over the course of 4 months. I put very little faith in the accuracy of the app. The car has started fine every time. Battery is fine :grin2:

 

My Myhyundai app has read 0% with a warning notice at the top since last October, which was the first time I'd ever seen this indicator. I have a 2015 Sonata. Dealer says battery is in great condition and bluelink help desk can't figure it out either. Pretty sure the app doesn't work. Screenshot attached.

 

Wow, that bad reading would make me very hesitant to trust anything else that the app says.

 

I know this has been discussed a lot. Just adding my experience... My battery level was in the low 70s and high 60s before I was out of town for a month. I left a battery tender on the car while gone. Came home to 98%. Drove the car, down in the 80s, sometimes in the 70s. Very short drives will bring this down in the low 70s. The battery tender will help bring it back up. One of the stated ISG requirements is battery charge level of 68% or more for ISG to engage. It does appear that driving the vehicle longer distances will get the battery level into the 80s for me. Based on what I see and what others have reported, I have to believe anything from the 60s up to 100% is acceptable and expected.

 

But how can 60% be “acceptable” if the ISG system will not work if the battery drops below 68%? Do you get my drift?

 

I seriously doubt that the battery reading shown in the My Hyundai app is anywhere near accurate. To properly test a battery it has to be under load, and when the vehicle is just sitting there after driving it should be close to 100%, unless you have an electrical problem.

I drove 150 miles last week on a trip and when I got home the app said my battery was at 77%. The only turned on for the trip was the radio. Later that evening it showed 80% after sitting in the garage for 2 hours. It magically went up 3% all by itself.....:|
