Battery Tesla or Duracell

It's a Tesla thing.

Tesla doesn't keep a buffer zone at the top end of the battery. 100% means 100% in a Tesla. Tesla advises to only use 100% when you need the extra range.

My tesla model y recommendation is 90%. I know lfp batteries are recommended to do 100% at least weekly. We do 90% but drive the car about 100 miles every work day so it doesn't even sit at 90% for very long, maybe 3-4 hours.

My 2015 Jeep Patriot's factory battery from Chrysler had one, until I replaced it last year with a Sam's Club Duracell special

I got a Duracell from batteries plus because it has a two year warranty. Starts strong so far, but it’s only been maybe 4 months.

I have a ‘21 (Dec 2020) M3 LR AWD w/19”. I’ve put 52K miles on it so far. Generally speaking, I’ve seen very little degradation.

I bought a used 2019 LR in 2020 and my estimated range is 302 miles with 48k miles.

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.

A month ago I bought a 2022 M3P with 7k miles, was at 310 estimated fully charged, now 280 all of a sudden at 10k miles.

Duracell killed 6 pieces of electronics of mine over 10 years. If you paid me, I would not use them.
