Battery OEM Hyundai or Deka

my 2022 Hyundai Ioniq 5 has 71k+ miles and coming up on 3 years of ownership. I plug in when, where, how I want. ONE thousand charging sessions. It has ZERO range loss.....300 miles per charge still. I have no battery degradatiion. State of Health = 100%.

My Mechanic had me get non-AGM style from Deka. I have the dual battery setup, and have drained my spare a few times already and it’s out performed the previous brands.

I really like the Deka ETX12. Point is these batteries are bulletproof. They last longer than any other battery I have ever gotten. I highly recommend them.

I currently run a Deka Intimidator in my rig and it's been problem free for 3 years now

Deka ETX15, Deka makes a great battery and they’re sold under a few manufacturers.

I use Deka for all of my cars and they take Minnesota winters like a champ

Original battery in my GF’s Elantra finally died today after 10 years.

Deka is the best I’ve found.

Yes and you can go the route I suggested earlier, with a Group 47 AGM , Deka brand. I paid $135 for mine 4 years ago at Battery Mart. Fit is good, just add a wedge under the battery hold clamp. Cannot leak acid due to the design. I run diesel farm tractors, too. AGM's are the only batteries I can get a decent life from due to the vibration. The extra capacity over the standard lead acid batteries is great for the cold morning diesel start. My point is that they are quite durable. An AGM for a Rabbit is not overkill when you consider the quality problems in regular lead-acid batteries these days.

My I6 battery died after 4mo and 2200km (1370mi). Car is sitting at the dealership awaiting warranty decision.
