Proud to say I take care of my battery pretty well! :D

Battery Degradation what!?

now before y'all pounce on me, i realize my miles are low, but i would like to try to get a new thread started for Model X owners to have a place to officially post their findings.

Below are photos showing my car charged to 100% this morning before i head to Knoxville TN today. I'm still at 251 miles!!

FWIW, at ~33000 miles I charged to 250 at 100% last weekend. It lost 7 miles in the first 7500 miles and has basically stopped since then. When it's below 20F or so it only shows ~245 though.

Fun, but really this isn't a good way to track degradation.

Battery charge levels are estimated.

Nice, that is what I get (251-252) on my regular 90D so be glad with it for a P90D. 250 is what the P90D is rated at by EPA at 100% so that's cool ;-) Especially since you have 22s, and OH isn't the warmest climate always.

The battery charge display does not take into account battery degradation. The only way to inspect battery degradation is compare trip meter readings WRT percentage charge left after journey. Ideally, for comparison, you would drive until battery is almost empty, new vs. old battery.

It's same as mobile phone battery charge indicator, full battery looks same in old and new phones, but reality is different (the charge runs out quicker in old phones, you get less talk time and less standby time).

I just hit 50k miles and I have 251 at 100%

The last full charge on my MX90D showed 261 miles:

Cool, but check out this thread and my post regarding this topic based on feedback I received from a Tesla Service Engineer:

X: What's your 90%?

X90D 263 here

I agree i posted this a little hastily and proved that i'm naive/newbie or whatever. I would like to figure out true degradation...if any.
