Battery Panasonic or OEM KIA

I had a 2004 Scion xb back in the day that was made in Japan. Had to get rid of it after the engine developed excessive oil consumption. Had a hell of a battery in it. Panasonic brand.

Yeah, the oem Panasonic battery is easy to kill. I replaced mine (2022 Turbo) with an AGM type. Most all batteries are made by Johnson Controls, under different names. The cheapest price I found was $179 with a 4 year warranty at Walmart. Everstart Platinum group 35. Was a 10 min job to remove and replace. They can even test your old one. The agm type is in the deep cycle family, it can be discharged quite a bit without any issues, the stock battery (flooded acid type) is easy to damage.

My 2019 Mazda 3 died on me randomly a couple months ago. The dealership ran a test on it and it came out fine. I changed it anyway as it was a stock 5 year old battery. It’s been fine since, even in the -20°C temps where I am.

I just replaced the battery on my eco drive from maybe 2008ish? Battery itself was 14 bucks on ebay, oem brand(Panasonic). Swap took 5 minutes.

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.

My original Panasonic lasted seven years in my car when new

Another is that the OEM Kia battery just sucks…they fail. The fix is to get a new battery that doesn’t suck. Kia will replace the dead one within warranty but you’ll get another dodgy OEM battery. Most people seem to trend towards buying a good AGM aftermarket battery for this.

I run Panasonic in ours, so far so good.

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.
