In my car (2021 Mach E AWD with standard battery), the battery state of health the first time I checked it was around 94% at around 48,000 kilometers. I’m not sure how accurate the car’s data is because it seemed to drop a percentage or so immediately after a couple of OTA updates. It sat at around 92% until between 80,000 km and 113,000 km, but now it’s says 92.5% at 120,000 km. Again, I’m not entirely confident at how accurate the car’s information is, but my range is still about the same as when it was brand new. I think I’m past any danger of manufacturing defects, so I don’t have any reason to suspect that the battery won’t easily last a couple hundred of thousand kilometers more.
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.
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.
I've never had any reason to regret my decision in the past 15 months of ownership, and I absolutely love driving it.
I replaced the battery in my '16 F150 last year - I'd say it had a good run. Went with another OE battery since the original lasted so long.
2020 SR+ 51K I get about 229 miles at 100%, advertised range was 250 when it was purchased new.
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.
My first Tesla battery died after 1.5 years of gentle use and the replacement they gave me is currently at 84%. Just like my 2 year old iPhone. Batteries degrade much more than these studies suggest.
battery life is astonishingly unpredictable. I drove 20 miles, but lost ~35 miles of range. Not driving crazy, either. Everything else is decent, but can't help but feel like it's a time bomb.
