Turn the steering wheel completely counter-clockwise and then go look behind the front passenger wheel. You will see the label on the battery pack. The last letter is the battery pack version you have.
2013 delivered in May of that year S85.
221 rated / 256 ideal at 90 %. Have 20,000 miles and a lifetime 373 kWh / mile.
Sounds low. They have revamped the software so many times I really do not know what to think. I rarely charge to 90. Usually charge to 70 or 80. Have supercharged six times. Perhaps because I park and charge on my driveway (no room in garage, of course)?

S85 delivered Apr 2013. "A" pack. 28,000 miles with 298 Wh/MI over the life of the car.
I get 225 miles at 90%.
Have range charged maybe 10 times.

As rhythm raced inside, the ship came alive
Is there any consensus on whether there's a tradeoff between what charging behavior yields "best range" and what yields "optimal battery lifespan"?
Elsewhere on the forums, I've read that keeping the battery between 20% and 80% is best for lifespan, and some have even said keeping SOC at 50% is ideal. But would that also be expected to result in decreasing range, or is this simply a matter of losing calibration when charge cycle deltas are relatively small?
My 90% has gone from 239 to 233 rated miles over the span of a year. This might be because I've been charging only to 80% most of the time, and I never go below 20%. Does the battery periodically need to be exercised over its full range to report accurate stats, and is it a good idea to do so? Haven't really seen an answer to this yet.
Nobody but Tesla knows for sure. All we know is that 20-50% charge is the best for the battery, but if the car isn't charged to 90% regularly, the battery gets out of balance. It's possible to get it back into balance with either many consecutive range charges, or just charging to 100% for a while(both are bad). Hot rodding the car with a low state of charge is also bad, so if you step on it all of the time, it's better to charge to 90%.

That's pretty consistent with me (you are a bit higher, but I have over 56,000 miles on my March 2013 S85). I'm around 218 Rated at 90%, and the big drop happened during the first year or so then remained fairly steady since.

Charged mine up to 100% + 30-45 minutes of what I assume was rebalancing, down to 18%, then back up to 90% for the first time in about 18 months. I recovered a mess of miles: was 227.9 at 90%, now it's 232.4. Much better rebound than I had hoped. 16k miles now, built in 11/2013.

My 90%?! About four beers...
My car's rated range at 90% battery state of charge? So far this summer 214 to 217 miles.

60,000 miles on the car, 41,000 on this battery that I know of (mine was a refurb replacement pack due to the contactor issues, before the service centers could fix them). My 90% charge is 238 miles, range charge is 264 miles (240/266 when installed). I always charge at 80A when at home, and supercharge without concern (although I don't have a "local" supercharger).
40s or cans? and is that including pouring one out for all the gas stations that aren't getting money from you?

Hehe, yeah, pints, and it depends on the beer and the head winds
What's a gas station?

It's interesting that your 90% is substantially above average (and above the standard "new" value of 235), but your 100% isn't.

265 Rated Miles is standard for the 85 kWh pack. My S85 came in spot on 265 on a 100% charge I did when it was nearly new, and I got around 240 @ 90% at that time.
EDIT: Although at that time, they only had two charging options: Trip (100%) and Daily (??? %) so I can't be sure about my early 90% numbers.
*shrug* If I walk out to the car within 2 hours of it completing charge it'll be at either 238 or 237 (238 seems to be there for about 30 minutes or so). A full range charge was 266 until about 2 months ago, when it dropped to 264 or so. Either way, it's not bad for a refurbished pack with at least 41,500 miles.
