Battery Bosch or OEM KIA

OEM KIA Battery

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

Bosch Battery

(for general reference Lion are one of the worst battery brands out there. Exide are OK but that's far too expensive. Bosch and Varta are generally the exact same product with different stickers on and are always good, and rarely all that expensive.

Pros: good, rarely expensive
Cons: far too expensive

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

I went to a Škoda dealer to look at a car to buy. The car was a Rapid 1.4 SE DSG which was advertised at £8995. The car was stored remotely from the dealer, basically in a field. The battery was completely flat.

Cons: flat battery
Vehicle: Skoda Rapid
