Battery Energizer or OEM KIA

I'm at over 90k miles in a 2022 Kia EV6 and haven't had an ICCU issue. All I've done outside normal wear and tear like tires is upgraded to an AGM 12V battery to solve crappy OEM battery problems

When i changed my battery in my Kia eSoul (same car, different brand) the only thing that happened was that the aux bat SOC said 255 for some time. Then car calibrated itself to the new battery and said the right value.

I typically use what is shipped with the packaging. Most of my red dots are trijicon and they ship with energizer so I will continue to use it. I feel the companies do their own testing trail and error with battery life and usage at all power levels under all temperatures.

Energizer. Better QC than Duracell imho.

Duracell lasted 18 months on my RMR 3.25 Type 2 on auto setting, Energizer lasted 23 months on same setting!

Having ran both Duracell procell, and Energizer lithiums in RMR's, the energizers last 3+ years. I've gotten 2-2.5 years out of Duracell.

Funny enough I also have an 18 Elantra and had my battery replaced recently from Costco. What I got was a:

- H6-AGM

- 760/120/70 cold crank amps/reserve capacity/amp hours respectively

the cars are decent, the customer service at the dealers, hit or miss.

the Vancouver (Coquitlam) dealership i bought my Kia from knew jack squat about my car - I basically just needed them to sell me a car, that I knew more about at the time of sale than they did.

went to a different one, and got a much better experience, they were willing to sit down and talk to you about what the problems were, what options were, etc. So in short, the early EVs (like the one I drive) were kinda iffy depending on your experience, could be great could be terrible, but the classic ioniq is one I would hands down trade in for. The extra cobalt inside the cells means the degradation happens less, it doesn't overheat as quickly, charges reasonably fast, and more efficient than tesla :p

Mine died at about 44k. Good news is Kia is fully covering the replacement and the mileage warranty restarts with the new battery

I'm at the third battery at 7000 miles and 6 months (2024 niro ev) and the battery is dead again this morning, like wtf.
