Battery Tesla or Duracell

Am folosit la cheie de mașina cu keyless go & entry, cele de la auchan țin maxim 4 luni, indiferent că folosești cheia sau că o ți in casa (daca e rezerva), cele de la Duracell țin un an și ceva.

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.

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.

I got a Duracell at Sam's Club for around $150, no prorating on 3 year warranty if it goes. Just a new battery.

Not near Utah but here on the west coast I use Powersonic or Genesis or Yuasa with good luck. For some reason all the Duracells I have purchased over the years fail about a year out of install.

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.

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.
