Battery Tesla or OEM KIA

I've never had any reason to regret my decision in the past 15 months of ownership, and I absolutely love driving it.

As an owner of a 2016 model S (bought new) with 228k miles on it, still on original battery with a range reduction of less than 15% compared to new.

Just replaced mine in my model 3, it lasted about 4.5 years before I get the alert on my app. Had it replaced in less than 20 minutes via mobile service in the app (there was already a tech in the area).

when we bought our 2024 Kia Sportage hybrid, the salesman was showing us around it and got around to popping the hood, I did not see a 12 volt battery.

I had a 12v battery give me a low voltage warning and they just came around and changed it.

It's a Tesla thing.

Tesla doesn't keep a buffer zone at the top end of the battery. 100% means 100% in a Tesla. Tesla advises to only use 100% when you need the extra range.

2018 M3P with 54K and it is right at 7%

My 2019 M3 with 50K miles says 288 miles today (310 original) but it has been far lower at times (255 miles) and bounces around.

2019 model 3 SR with 10% loss based on full charge at 52k miles.

Biggest issue was it ate batteries, never had a car go through so many batteries
