13% Degradation for 2017 75D at 84,000 miles

[Raroia]

Does about 13% degradation seem reasonable for a 2017 75D with 84,000 miles?

I have about 17 months remaining on HV battery and DU warranty.

- Stored mostly in underground garage that is not conditioned (90F + in the summer)
- Charged about 50% DC (FUSC SC01) and 50% mobile charger

Any input appreciated. I live right by 057tech and plan on getting their warranty at some point.

Absolutely LOVE the car, it is so awesome.

Yes. My 2015 85D reached 15% degradation in spring 2020, and was still at that threshold the last time I did a Supercharge-required trip earlier this year.

My 2016 S75 was probably pretty close to that at the same mileage. Degradation slowed down to almost nothing after that, reaching 15% at 175,000 miles.

As for whether it's normal/reasonable - since your battery has no degradation warranty the only possible answer is yes. Tesla will not do anything for you until it outright fails.

Thanks, I appreciate it

It's in the ballpark - I'm at just under 12% after 107000 miles.

Hi. How do you guys get the degradation percentage? Is it by running the service menu battery health test?

Make sure your display is set to rated miles. So, say on a 2012 P85 that was originally rated at 265 miles at 100% State of Charge now has 225 rated miles, then you have a 15% degradation. (40/265=15%) or (225/265=85%)
