Battery Tesla or OEM Mercedes

Historically, OEM Mercedes batteries are really good and last many years.

At 4 years both our Teslas appear to have essentially the same range as new. Which is to say a bit lower than Tesla advertised but no worse

Everyone's suggesting things that might save you half a percent or so, but no one has pointed out that by driving at 80mph, you lose *around 30% more battery* than if you were doing 70mph over the same distance

I'm going to turn 230k miles on my 2018 model 3 tomorrow. The only time it has been to a service center is when the 12v battery died on a road trip. Other than that, I've put tires on it. I'm at about 21% degradation but everything still runs as it should. I'm hoping to get to 300k miles on the original battery.

For my Mercedes sprinter I had the same battery in it for 10 years. I went and bought it at the dealership. Since the last one lasted 10 years. I shouldn’t have a problem with it.

Warranty: side repeater, spoiler, battery (at 82k)

After 3 years, my Tesla Model 3’s battery range dropped about 7 to 15 percent, which seems pretty typical based on what others report. It isn’t catastrophic, but it is definitely noticeable for anyone doing longer trips.

Yes. Mine was from 2020 and quit without warning March of this year. Contrary to what some people have said, the car won\u2019t always warn you that the battery is weak.

Yes, my 2021 battery died mid 2024. No warnings, no abnormal behaviour. Luckily it was still under warranty and the towing and repairing were free.

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.
