well done! Thanks I have a 2019 too

In Europe, this Hyundai Ioniq phev battery has a size of 209x175x190 mm (wxdxh). That is a standard battery size, easily available. However, this Hyundai battery has its + pole at the left front, which is rare these days. That is not on offer by the regular (European) brands like Varta and Bosch. I got a "VMF 54464" battery for about €90, which was a perfect fit. Note that this battery also says 'calcium' as mentioned earlier in this thread.

 

Thanks for the dimension info!
Details of the Napa 6526 battery 450 CCA seen above are here: https://www.napaonline.com/en/p/BAT6526
and it's Calcium-enhanced.
But sadly does NOT state the diameter of the terminal posts. Here in UK there are 2 types in use, the old UK size ones which are larger than the Japanese ones.

I'm going to look at tayna.co.uk to see what batteries might be suitable for the Phev.

We already know the Yuasa YBX 3056 (36 Ah) or better still YBX 5056 (40 Ah) is good for the 28 & 28 Bevs.
This battery has the smaller Japanese style posts! so BIG qn is, what style does the Phev use? Does it use the larger ones because it's a substantially bigger battery?

@jos.van.eijndhoven Is the height 190mm measured to the top face of the pastic box bit, or to the top face of the terminals?
Tayna measurements are to the top of the terminals.


The Phev takes a bigger battery than the 28/38 Bevs.. Tayna have standard sizes, as far as I can see the ones suitable are:
Size 004R: 202 x 173 x 225H (might be a bit tall? But looks to be plenty of headroom in the pics!)
Correct terminal layout, but looks to be UK not japanese terminal sizes (?too large?), and lacks retaining lip along the edge at bottom. So forget this one.

Size 012: 210x175x190H Wrong terminal layout, so forget this one.

Size 077: 210x175x190H Correct terminal layout! All these have retaining lip along the bottom edge - good!
BUT they all have the UK "larger" terminal sizes.

Acc to Tayna, the UK terminals measure 17.5mm dia a base of -ve post, 19.5 at base or +ve post.
Japanese terminals are 13.1 dia at base of -ve post, 14.7 dia at base of +ve post.

So please can someone with the Phev measure the post diameter & tell us whether H are using UK posts or Japanese posts!

If H use Japanese size posts, then we're out of luck as far as Tayna are concerned, I think.
If H use UK size posts, there's quite a few mfrs making batteries which should fit. Vent might need different pipes, but that should be easy to fix.

edit: Just done a v approx guesstimate based on -ve terminal of pic above, and I make the base diameter of this to be in region of 21mm. This looks closer to UK size than Japanese, but the photo isn't taken square-on so this isn't conclusive. But I'm hopeful!
Of the several 077 size batteries at tayna, only 2 are arted the same 450A CCA.
these are:
Exide 077SE
Enduroline 077
and both are 50 Ah capacity. So these 2 look like the best fit so far.

 

I replaced my 12V battery today with the Napa 6526. I was concerned about not having the vent connection, but the battery has vent attachments on either side, bit they are a flattened oval shape rather than round. It is not clear if each half of the battery vents separately, which would require 2 vent connections.

 

Not sure what a vent attachment is, but I'm still using my battery.

 

And I saved over $250 vs the dealer price of $408.

 

According to the NAPA specs, the replacement is a "Calcium-calcium alloy provides minimal water loss and very little gassing". Even so, I'm planning to adapt some plastic tubing so that I can connect the vent. Will look at it this afternoon.

 

I added the "plumbing" to my battery to vent the fumes. I bought some 5/16 ID vinyl tubing and a tee connector. The tubing would stretch over the vents on the NAPA battery. Connected the two vents with the plastic tee and then added a piece of tubing to connect the vent hose in the car (which went completely inside the tubing). About $8 in parts. I may go back and add some angle connectors so the connections at the battery are not stressed to where they pop off. It would also allow the tubing to fit more neatly along the sides. Latex rubber tubing would probably grip better.

.

 

U.S. Department of Transportation regulations mandate that all passenger compartment battery manufacturers incorporate external venting mechanisms to mitigate the risk of fume release in the event of battery boiling.

 

Excellent Thread: my son's 2019 Ioniq PHEV died and my NAPA store did not have a 6526 in stock. They did have a 7526 which has a longer warranty (24-month) and more power (665 CA, 540 CCA). The price was $199. It is slightly taller than the battery that was in the car, but is actually a better fit to the bracket.

 

We had the same problem just over a year ago. We were able to crawl back and use a portable charger to get the car going.

Good news is several years later the car was totaled while parked in a hit and run. We no longer have to work through CHECK ENGINE LIGHTS or wait for three months for a dealership appointment.

The care was fine, but the dealership was impossible. Any little problem becomes a big problem if it's a Hyundai. The happiest day is seeing the last of having to deal with Hyundai and the dealership.

 

我的12V电池也坏了。根据你的帖子，我从NAPA网站订购了一块NAPA Proformer 6526电池。安装新电池时，我发现它没有通风孔。现在电池工作正常了。
