It seems highly unlikely that a new unused pack has been sitting around for 9 years. More likely a reman that wasn't restickered, it's happened before.
But it has been restickered, it clearly says "REMAN" right on it.

Just because Tesla used to add a R# to the serial number indicating the number of times it was remanufactured, doesn't mean they still do that.
 
Tesla S85P 2014 / 110'000 miles here. I am in Europe.
I never charge to 100% so I can't tell you the range at 100%
I can drive between 100 and 130 miles on a single charge (80% to 15%)
I suspect the battery to be very deteriorated... What do you think ?
Few months ago the car stopped completely on highway when the battery reached 7% so I am now very careful to never go below 10%...

See attached a recent trip I did in Italy. Mainly highway at 80 miles per hour. For 95 miles done, the battery dropped from 82% to 20%

Belgian neighbour here.
My opinion is that the car needs to be charged to 100%, then driven to below 10% now and then.
Driving below 10% (after charging to 100%) is something I do when close to home, just in case it would fail like yours, to avoid being stranded during vacation.
We charge to 100% each time we go on vacation or longer trip (3-4 times a year). Give some more miles and don't think it hurts the battery really.

I believe it allows the BMS to recalibrate and be reliable. I do this in the hope the BMS remains correctly calibrated and will not stop the car like yours, way above 0%. I avoid going below 5%. (*)

That trip example is a bit surprising, and 62% needed seems high. But depending on outside temperature, can be normal. ABRP announces 50% needed.

I recently drove 286km (180 miles) from 97% to 5%, with outside temperature in the morning (one way) just above freezing, and return around 12 degrees Celsius.

Looks similar to my car.

Again, probably close to my car too. I calculated the battery lost around 12%. Not bad at this mileage.

(*) I avoid going below 5% more to have some range left in case there is a deviation, unforeseen issue or problem at the charger or on the way.

So this is your original battery?
 
I don't think there's a way to know the percentage of all 2012-2015 Model S's that have had their battery packs replaced, but I'm curious about the owners here on TMC. In addition to answering the poll, if you want to provide any amplifying information such as miles, rated range at 100%, etc., feel free to post that as well.

I'm still on the original pack with my 2015 Model S 85D ~78k miles and only ~202 miles at 100% charge.
2013 S P85+ 192,000 miles 190miles at 90% or 215 miles 100%. I supercharge 90% of the time

Happy to see this thread. Have a "new to me" '15 70D (7/15 MFG date) that I purchased with <10K on the odometer in Jan '16. 119,945 miles with original battery pack and DUs. Car has taken us on some really awesome and long road trips in the U.S. Excluding tires and electricity my total out of pocket maintenance costs have been $4670 (biggest bills were the front sway bar links, parking brake assembly replacement and replacement of front lower control arms). According to Teslamate I'm at 10.6% degradation and last charge to 100% was March 8, 2024 at 118704 miles. I've got things coming today for SMT as I want to see how it compares to Teslamate numbers.

Your numbers look pretty accurate. I would expect SMT to match closely to the TeslaMate values you have shown, although what TeslaMate calls usable is not really usable, unless you include the 4.0 kWh buffer. In SMT, your 61.5 kWh equivalent value is called Nominal Full Pack.
My car is the same year as yours, so it is a good comparison. I only have about 55 kWh compare to your 61.5, but I have close to 170k miles total on the odometer.

Got everything working for SMT..... all this taken at 70% SOC

Nominal full pack = 61.7kWh (very close to TeslaMate)
CAC Imbalance = 3.40Ah
CAC min = 206Ah
CAC avg = 207Ah
CAC max = 209Ah
Cell Imbalance = 6.00mv

I'll likely start tracking monthly/quarterly those values. Fingers crossed that the "classic" EV in our home (have a '21 LR MY and '21 Bolt) continues to be reliable for another 5 years .

Oldest car I ever owned was a '99 Accord with 250K miles on ODO before I sold it for $4K - 14 years after buying it new. Would love to have the MS70D go 15+ years. :)

What version of SMT are you using? I didn't know you could get the CAC values from the older cars.
Where did you get the parts (cable and adapter for SMT)?
 
2013 S P85+ 192,000 miles 190miles at 90% or 215 miles 100%. I supercharge 90% of the time
I have a 2015 MS 70D still with original battery and drive train, 105,000 miles (mostly CA miles) , MCU2 upgraded.
Still charging I think to 215-220 miles. I try to drive efficiently and avoid supercharging. Keeping fingers crossed I might make it to 200,000 miles! Wishful thinking??? Last time in service was told 4 bushings torn and need replacement! Great to hear from other 2015 70D owners regarding their battery and maintenance experience.

What is your llifetime Wh/mi? I am at 292 Wh/mi lifetime after about 170k total miles. If I am driving moderate speed on the freeway, I get around 265 Wh/mi.

I reset both my trip meters 32,000 miles ago. They both show 265 Wh/mi.
I'm a madman for not driving fast. Supercharging only on road trips. I've done quite a few road trips from SoCal to Seattle, Utah, and Phoenix! Your 170k gives me some hope for maybe a few more years!!
 
We have a (originally) 2016 model 60. As I recall, I discovered on this forum that all of the 60s, 70s, and 75s have the same physical battery that, in the case of the 60s and 70s, are software limited. At the time there was an upgrade available to upgrade the 60 to a 75 for around $5000+(?). About 6 months in, that number went down to 2k to upgrade to a 75 and we did it. We have almost 80k miles and get 216miles at 100%, about a 10% degradation. Half the miles are local, 25-30k worth of trips of 1500 miles or more, and free supercharging. So 90% of the charging is at superchargers. 300Wh/mi.

Interesting! 👍
 
2014 MS60 12/14 manuf. that the SC has told me started life as an MS40 - how can I confirm that? And if true, when was the cap removed?

A couple friends with Chevy Bolts, one a 2017 also with a 60kW pack, questioned my range estimate and questioned if the 40kW cap had been removed. They say they get the full EPA milage estimate whereas I don't. And my MS60 is 1200 lbs heavier than their Bolts so no big surprise it'd have shorter range!

But it got me questioning things so this past weekend I ran the battery down to 7% SOC and then charged it to 98% SOC which added 50kW to the pack during the charging session showing it's not capped. See attachments.

EPA estimated range at 98% is 190 miles down from the original 208 miles at 100% charge. That would equate to ~194 miles @ 100% which would indicate ~6.7% degradation over 9+ years.

The pack appears to be original. It's got 44.4K miles and has never been licensed for SuC so for the past 6+ months I've owned it, it's been charged at home at usually 9kWh L2 rate.

Tomorrow morning I'm having my ICE mechanic check the speed sensor for LDU coolant leakage. Fingers crossed!

If you can charge past 68% the cap has been removed. (That is how the cap was implemented on the Model S 40.)


Nobody here is going to be able to tell you that.
Thanks, yeah, thus the test this past weekend.

Yeah, I don't think I'll ever get the true answer on the 40/60 kW cap. If you read my earlier thread about trying to enable the car for CCS fast charging, when it didn't work, I was told I first needed to remove the 40kW cap, which clearly is no longer in place. Later, working with the SC to try to find a way to get SuC licensed, they kept coming back to "originally it was a 40....." ignoring that it no longer is a 40..... Or maybe the cap got removed but the records never got updated....
