vs
Battery Tesla or Deka
Deka. Solid battery.
Pros: solid battery
My Mechanic had me get non-AGM style from Deka. I have the dual battery setup, and have drained my spare a few times already and it’s out performed the previous brands.
Pros: outperformed previous brands, withstood draining
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
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).
Pros: replaced in 20 minutes
Cons: lasted 4.5 years
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
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.
Cons: battery died prematurely, replacement degraded quickly
