Shouldn’t that have reset the battery warranty to 4/50 from install?No, not new -- I misspoke -- it was a remanufactured battery, 85 kWh, 400V, p/n 1088815-01-D. Installed July 2020, five months from warranty ending. The fact that it failed 25 months later is basically all the reason I need to avoid putting a "remanufactured" battery into the car -- for $6500 more I am going for the actual NEW battery.
And, yes, in a kinder, gentler world Tesla would say "Failed after 25 months? Should last 4 years. So even out of warranty, let us fix that for you gratis." But this ain't their business model.
No, because all they have to do with a battery replacement under warranty is honor the original 8 year warranty, which in my case ended December of 2020. When someone pays out of pocket for a battery, the 4/50 warranty kicks in.Shouldn’t that have reset the battery warranty to 4/50 from install?
If the original 85 kW packs had 265 miles at 100%, an increase to 87.5 should then be 273 miles at 100%, so what I am seeing is in the ballpark.
charged the car to 100% twice and it showed 269 mile and 270 miles,
with the charging remaining above 104 kW and 330 mi/hr to at least 50% SOC and tapering to 80 kW until 100%
the label on the battery specifies 350V but doesn't mention kW capacity at all.
Just Tesla being vague as usual.There's definitely some weird stuff going on over at Tesla with regard to the 100-type S/X modules. While I'm fairly confident as to what is actually happening, the problem is that 99% of the data and info I have is not 100% conclusive in this regard. Suffice it to say, I'm not convinced that the cells that are going into these "new" 14-module packs are actually new in every situation The chassis are easy to make. (If it's old stuff in a new shell is it still technically new?) The cells, not so much.
As for the labeling of the older packs, there's some huge threads (some started by me) from ages ago where this is discussed in length... but overall seems just to be unnecessary marketing BS. They could have just as well sold it as the Model S 80 and no one would have cared. At least then the rounding would have make some sense.
I'd suggest a CAN tool/CAN logger to validate.
@Droschke, I can't recall exactly what it was pulling just before 100% SOC -- I think it held 80 kW all the way to the end but maybe it tapered down from there in the last minute or two. I wasn't planning to charge it to 100% again soon but perhaps I will and will report back. I also didn't notice if I had regen available at 100% -- that would be interesting to know as I guess it suggests that there is more capacity if it's available. I'll report back if Tesla responds but I'm not holding my breath.
@Droschke , Thanks, very helpful. I will note these things and report back. It's definitely interesting that we both get precisely 270 -- this suggests to me that the batteries are software limited despite their assurance that it wouldn't be. I've messaged them and I'm going to press this issue, even though I'm fine with 270, simply because they told me 280, and I based part of my decision on that. One hurdle is that almost no one I talk to in the service department seems actually to know anything about this stuff.
