vs
Battery Tesla or OEM Mazda
Tesla on nmc battery drops around 10% after 8 or 10 years (can't remember exactly) from what I read. But lfp battery is inherently able to have longer life span and charge cycles. On top of inherently having ability to be safer / less explodey.
Pros: longer life span, safer
Cons: 10% drop after years
For context, I have a first generation Tesla Model S - 2014. It has 215,000-ish miles on it. The battery capacity has gone down by about 10-12%. It still runs and drives like a dream. It's on the original battery.
Pros: runs and drives great
Cons: battery capacity decreased
Mileage: 346000 km
I've never had any reason to regret my decision in the past 15 months of ownership, and I absolutely love driving it.
Pros: 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.
Pros: original battery, low range reduction
Mileage: 366939 km
I don't want someone else's crusty ass battery. Charge times are already low and are plentiful (Tesla at least), I don't see the utility of swapping the battery out when I could stop for like 15 mins.
Pros: charge times are low
Cons: unnecessary complication
Vehicle:
Porsche
2020 SR+ 51K I get about 229 miles at 100%, advertised range was 250 when it was purchased new.
Pros: 229 miles at 100%
Cons: range loss
Mileage: 51000 km
162km at 42% battery is still kinda poor for 2025.
Cons: poor range
Vehicle:
Mazda
My 2025 CX-30 battery is already showing signs of dying but I bought the car in April but then had surgery in June and only went back to work today so it sat for long periods and I do leave my dash cam in parking mode. It might come back some after being driven more or it might not.
Cons: showing signs of dying
Vehicle:
Mazda
Knowing what I know now I would. My 2021 was built in July 2021 and about a year ago my car bricked on me and wouldn\u2019t start. I had zero warning ahead of time.
Pros: mobile service dame
Cons: car bricked, zero warning
The OEM batteries are shit. It died around the two-year mark.
Cons: poor quality, short lifespan
