Dead 12V battery in 2019 Niro EV

I would not be surprised. I had a brand new Honda a few years ago and the battery died when it was just shy of two years old. I have a June 2019 built Niro now and the 12v battery died a few weeks after I purchased the car. I jump started it then and it has been running just fine since then.

 

What's the best battery for our EVs?

 

Have look this guy has the answer, although if in auxiliary mode the battery won’t drain. I’m a bit surprised as with my Kona if left as you did a warning is displayed.

 

In this interesting video mr. EV monitor’s the 12 V battery.

 

I have a 2019 NIRO PHEV EX. My 12v battery went dead on me once.

I did as others have already suggested and bought a Battery Booster, a NOCO BoosterPlus GB40. This stays in the car at all times. It is a very simple matter to immediately start the car if the 12v battery is dead.

We camp out quite a bit and coming back to a dead 12v battery in the wilderness with no options is not going to ever happen to me. It is also a tool that I can use to render assistance to individuals needing a jump start.

 

Can you provide the battery info form the one you purchased, everywhere I ask, they just tell me they don't have that battery and I really don't want the same crappy one.

 

Here is a copy of some research I did for if I have to replace our 2019 NIRO PHEV 12v Battery:

I did go to our Advanced Auto Part Store to check out a Battery they had in stock. It is a DieHard H4 Model with dimensions almost exactly like our PHEV Battery. Its price is $189.00- about $30 above what the KIA Dealer quoted for their battery that they would have to order.
The DieHard Battery has a 3 year year warranty.

Disclaimer: did not purchase as I don't need it and of course did not try to install it only visually looked at it to confirm measurement and compatibility with battery hold down system on our vehicle.

I was very happy to find a replacement battery locally at our towns part store.

Here is a link to the Battery (currently they have a sale on for $20 off on products over $100)

Battery, Group Size H4, 480 CCA H4: Advance Auto Parts

It also has vent ports on each side to hook up existing vent hose.

Take your old battery with you and you will see this is an exact replacement. H4 Group batteries are the same spec as our NIRO PHEV/EV 12v batteries.

Of course the vehicle fitment software does not show if fitting the NIRO as the Niro PHEV is not popular enough to be researched and listed in many suppliers databases.

 

Here is a link to the KIA spec for NIRO PHEV/EV 12v battery specifications.

Scroll down to the Battery Specification section and then the information blow that will tell you dimensions etc.

Kia Niro : Specifications : Engine Electrical System (kniro.net)

 

Some DIY and dimensions are not so a issue

 

The battery shown in the video above would not come close to fitting in the space provided for the PHEV battery.

In the video the installed replacement battery doesn't seem to be setting in the battery tray properly but is on top of the tray.

 

Great video, huge battery though and I wonder what Kia would say in regards to car warranty. I measured mine and found some similar sizes and the ones in Walmart have 5 year warranties. I'm in Canada so we have different choices. I think I'll pull it and go to Walmart and match it.

I realize that I'm replying to a post that's over a year old, but I think that what I have to say is important.

I sure don't feel comfortable with GM's approach. When my 2017 Chevrolet Bolt EV was a year and a half old, I parked it in my garage one night. It had 160 miles of range, so i didn't plug it in. The next day when I tried to use it, it was totally dead. On investigation, I found that the 12 V battery was dead. I jump-started it, following the directions in the owner's manual. That woke it up so it would turn on, but it would not shift into drive or park. I left it charging for 45 hours. It still would not shift into drive or park. It had to be towed to the dealer (that sold it). The tow truck driver turned on the emergency flashers, and they worked fine. The dealer claimed that when they received it, the 12 V battery was dead, and nothing else was wrong with it. They said that nothing was wrong to cause the battery to die. So, I had a car that could become undrivable unpredictably, perhaps when moving at highway speed. Since my car had nothing wrong, I concluded that it must be normal behavior for GM cars with nothing wrong to have to be towed to the dealer. I'll never own another GM product. I am now the happy owner of a Kia Niro EV.

 

The first thing I though when I read the first sentence was why did he buy GM? Lol
Thankfully you've learned your lesson. Their answer when the bolts battery was catching fire was to park it 50 ft away from basically everything!

So I will looked around for batteries for my car cuz it was randomly giving us issues and instead I just bought one of those battery jump devices and it has been fine since. Kiss answer was you need a new battery and it's $200, which is total crap. I can size out of battery that will work in Walmart for under $200 and it comes with a 5-year warranty
Cad dollars.

What is the expected life of the 12v battery? I've got a 2019 with 69K miles and starting to wonder about it. In my ice cars the batteries seemed to last 3 years.

 

3 years is basically what I read

Do you have a battery # from Walmart to fit our vehicle's. Thank you.

 

Well I just measured the width and length and as long as the height wasn't too different I found two I like.
I haven't swapped it yet and will do it on the weekend and let you know which one I went with.

Thanks
Appreciate it.

 

I changed the battery tonight. All I did was pull it. Put it in a Walmart shopping cart and find the best match in the aisle. I went with the one in the photos, I'll look at my receipt for a number but I didn't even know the price until I paid. It was $137 and they charge $15 core which I got back because my gave them the old battery. The battery was about the same size and had the same type of base to clip in perfectly. I could not put back the negative cover and I think I broke it taking it off anyway..lol

 

I, too, have been confronted with an inexplicably dead 12v battery on several occasions since getting the drive motor swap on my 2019 model. Yes, I have the aux battery help turned on. I now suspect that the 12v battery that came with the car is crap, and on its last legs after three years; that the symptom presented after the drive motor swap may be coincidence, maybe not. Anyhow, I'm going over to Pep Boys tomorrow and getting their top of line replacement battery; we'll see what happens next. More to follow...
