Battery degradation after 8,700 miles...

[overthepond]

New here, just got delivery of my first Tesla, a used Model X 2016 90D with 8,700 miles.

Charged for the first time maxed out at 237 miles.

Left it overnight unplugged, and woke to 229 miles.

Car was delivered new early 2017, so ~4.5 years old.

Looking at some other threads of battery degradation, I suspect it's the age of the car that's resulted in this ~8% drop and/or a calibration issue.

Does that seem reasonable?

What you're describing is vampire drain which is the loss of charge when the car is unplugged and sitting idle. This is perfectly normal. Battery degradation is when you charge it to full again and you get less than the 237 miles that you're currently getting.

Yours is an interesting data point with such low mileage. Your range seems reasonable. I originally had a 2016 P90D X.

FYI, on related thread on X 90s : Model X 90kWh battery pack degradation

Thanks, understood.

Is 237 (down from 257 new) reasonable after 8,700 miles and 4.5 years?

I've seen 6-8% degradation quoted, but that's typically in the 20-40k mile range from what I can tell.

I suspect the variable here that might matter is time. 8,700 mileage is obviously low for a 4 and a half year old car. I haven't been able to find anyone with such low mileage after this long... presumably most people drive more than 2,000 miles a year!

Not sure what to expect.

Degradation in the early years of ownership seems to be more about time than mileage. My 125,000 mile Model 3 is seeing the same degradation as the rest of the fleet of the same age. We'll see how that trend continues as age and mileage continue to increase. 90 kWh packs in S and X seem to have a little more initial time degradation than other packs, but that appears to be leveling off.

Good to know, thanks!

Just wondering what setting everyone is getting these numbers from?
Is the distance set on "Rated" or "Ideal"?

 

[Harvey Danger]

Rated

Rated

ideal is more realistic than the 2 weeks for fsd

I heard both charging cycles and age play the role of degradation.

My X shows 366 miles at full charge now

so I threw it on the ground
