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.

Pros: settings remained intact
Vehicle: Mazda

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.

Pros: no issues, reliable

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.

Pros: batteries protected by design
Vehicle: Kia

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

Pros: lasts longer, 7 year warranty
Cons: died after 3 years

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.

Cons: battery replaced, carplay issues
Vehicle: Kia
Mileage: 5000 km

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.

Pros: decent at starting cars
Cons: trash for deep discharge
