ICCU died last week and just on a 2 week wait for parts.
Unfortunately it also led to the death of the 12v battery due to rapid discharge, which workshop argues its part of wear and tear with only 2 year warranty, price of replacement $560.
Trying to put forth the argument that it failed only due to the iccu failing. it's a consequential loss, not from wear and tear and I should be covered along under the Australian consumer law.

Despite that, I still want to replace the oem 12v.
Can't find a shred of info on it, is it some proprietary shape or design of the group 65 agm?

The whole HKG group seems to be riddled with this iccu (new vehicles still have the same part) and 12v battery issue, surprised there hasn't been some group action of sorts.

Have you looked on the Hyundai parts site? I would imaging it is used on more than one model, including Kia. Also search for photos of battery installation. I finally identified the Korean manufacturer of my original GV80 "reverse terminal" battery via installation pics on various forums and YouTube. From there I found a local dealer and saved about $300 from what Genesis wanted for it. Not sure if it would help at all but the product name is "Rocket Battery" and is a large Group H9/49 for the GV80. I suspect the 12v on your GV60 is smaller. A lot of GV80 users have indeed switched to the Group 65 because it is easier to find in USA with the reversed terminals our vehicles need. I preferred not to do that due to the reduced CCA and reserve capacity, but if it is regularly used and kept in a climate controlled garage or in milder climes, then it should be fine but maybe not last as long. Are you not able to access the battery in your car to see what it looks like, specs, and product label? See pic for mine.

One other thing...If you have not already tried or determined it, before you spend the $$$ on a new 12v, I would take it out, put it on a good AGM charger and then test it when it reaches 100% (or whatever max it goes). That one may be perfectly fine even though it fully discharged.

And dont reinstall it until they fix the ICCU.

Thanks, work shop can't it won't charge, now I don't know if they bs'ing me or never bothered.

Also not very forthcoming with details on the battery.

Is the cradle on the battery very specific ie height and base molded? Found potential replacements but it's taller and longer slightly.

Its your damn car! Make them give you the old battery. Or make them guarantee to replace it under warranty.
It is theft for them to keep the old one and then say you have to buy a new one!

Once in hand, you will then know what specs, model etc. you need for a replacement, exactly, and you can also charge it yourself and test it!

I am not at all sure if the clamp down unit on the eGV70 is custom fitted to the battery size, but I can definitely say the one on the GV80 is so. There is a little "play" but not much. You can usually go smaller but not bigger. But if you go smaller, generally you are downsizing the electrical specs as well which could affect both warranty and performance of the car. And you would need to shim whatever gap might be left to make sure the tie down is fully secure.

In the case of the GV80 you can go a little taller with longer bolts, but since the battery is located under the back floor, if you go too tall, the battery hatch and thus the rear floor/hatch board will not lay flat.

You also have to make sure whatever you do, your battery has a vent hole connected to the vent tube that vents to the outside of the vehicle to prevent explosive gas build up. It is a low probability danger risk, but one none the less, and most states in the US mandate that batteries installed in the cabin of the car (or in the trunk/boot) are vented to the outside. It is very easy to connect the vent tube which is already in place in the car to the battery, but if you go with a non-spec battery version, then the vent hole might be located in a different/difficult place or may not be present at all--both bad options.

In any event I would not buy a new battery unless and until you have your hands on the old one.
You dont want to add to your problems by buying the wrong one.
And as I mentioned, in the GV80 at least, the battery terminals are in reversed direction to almost every other battery that size.
Get the old one, take it in to a parts store that does battery testing, ask them to charge it fully, then to test it. If its fine, you're good to go, if not, then they have the exact model of what you need to replace it. In the US the bigger auto parts chains will usually do the testing for free and the new installation for free as well if you buy the battery there.

Good luck. Dont let them push you around. Let us know the outcome!
