Battery Tesla or Duralast

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).

I replaced mine in my 2018 GLE63s with an aftermarket one from Auto Zone (Duralast Platinum). I finally got my start/stop feature back which I had forgotten about and also forgotten how annoying it was to have it ????

I did just replace the battery in the Trans Am in the fall after 15 years (bought when I picked the car up - I really got my money's worth on that Duralast). It had never been on a tender and that car sees maybe 1500 miles in a big year. But of course it also has virtually zero parasitic drain. I didn't even realize how weak it was progressively getting until I had a no start moving it out of the garage for a wash. It started so much easier on the new batt, I was actually laughing.

I had a 12v battery give me a low voltage warning and they just came around and changed it.

I'm about to replace the battery on my 2013 acura tl 3.5L, looking for some advice on choosing between two batteries. The two batteries im looking at are the ACDelco Advantage 24FS or the Duralast ProPower Plus 24F-DL. They are similar in specs, same CCA though the duralast does have about 100 more cranking amps and 17 minutes more of reserve time. The acdelco comes with 18month warranty while the duralast has 2 years.

If you actually worked at AutoZone and knew anything you know the duralast golds are decent.

As promised: 2019 M3 LR , 55k miles/88514km, latest Tesla Battery Health Test 83%

A bit worse than expected.

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.
