Battery Tesla or OEM Volkswagen

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.

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).

My 2014 jetta TDI does the exact same thing as in your video when the battery is dying. I've had the car now for 6 years and it's happened 3 times. If the alternator checks out fine, then I would attempt a new battery.

Change it when it can no longer meat a battery test to spec, which has good margin before it starts causing issues, like freaked out ECU or hard starting.

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.

On a Jetta, it will leave you stranded, and it being a VW, the symptoms will be nothing like a dead battery, most likely.

I recently had to sell my 2013 model s for scrap value because the battery was out of spec. Tesla wanted 25k to replace. It was right at 200,000 miles.

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.
