Battery OPTIMA or OEM KIA

Even though the battery tested fine the problem went when I replaced the battery.

Love the optima redtops, seem to last forever

Finally pulled the trusty old Panasonic battery out of my CX-5 and replaced it with an Optima Yellowtop. When I buttoned everything up, I still had my radio stations and settings right where I left them.

Buy a nice battery. I bought used 6 months ago and did a week of nightly research first, by FAR the biggest complaint was the battery going out or having constant low messages. I put a yellow top in mine a few days after getting it, not one issue this far.

Also, most car manufacturers know that customers are generally bad at doing the "correct" thing, so they protect their batteries by design.

When you are charging to 100% you are actually closer to 95-97%, when you run your car to 0% it's actually 5-7%

All because it's easier to show you another number and build the protection into the system, than to change people's habits.

Get the battery from the dealer. It lasts longer and has a 7 year warranty. The Optima Yellowtop died on me after 3 years.

Of course you do. 16-19 kWh/100km to 20-23 kWh/100km. Kia EV6.

I bought a ‘24 GT with 5k miles and regret it every day. The battery had to be replaced at 9k miles and we had a loaner for a 5 weeks. Everyday issues like Carplay not working 50% of the time and the backup sensors being way too sensitive drive me insane.

Fwiw optima batteries have been garbage for the last 20 years.

Optima batteries are absolute trash for deep discharge use. Their quality is also not what it used to be. Anytime I see them in marine use, I swap them out for a proper AGM. Only thing they are decent at is starting applications in cars.
