New 85kWH battery for my 2013 P85+

Got my original battery pack revision "B" (unsure of the part#) replaced over the weekend and just picked up my car. To my surprise, I now have a new battery showing a ~92% charge to be 265mi and according to the app, 100% is 288mi!!! I initially thought I got a 90kWH pack as a replacement but when I picked it up, battery label shows a part# 1014116-00-A with 85kWh, 350VDC (vs the old pack 400VDC) Hopefully this pack does delivered the original performance or more, but my initial feeling is that my car is slower - but that might be because of the P85D+ loaner that I was driving for the past 2 weeks. I will see if I can talk to someone knowledgeable at Tesla to see what I can find out. In the meantime, what do you guys think of this?

Thanks for the reply guys! Battery Label is attached as well as my Tesla app screenshots (Yes, they are rated not ideal)

Ucmndd, I think you are right on that. I am just hoping my P85+ can take full supercharging speed as well as not suffer any performance downgrade (I think original pack is 400V)

Super interesting! Seems like you're the first person reporting this battery in the wild. Wonder if this is a precursor to an impending return of an updated "standard range" Model S/X.

Indeed, it does show up in the Tesla parts catalog now. Of note, this is the ONLY 85kwh battery that is still listed in either the 2012-2016 or 2016+ Model S sections of the parts catalog.

I believe you might be right again about the return of standard range! (just checked Tesla' - it hasn't return yet. Let's give it a week or 2!)

Tesla has been able to coax some great performance out of 350vdc batteries (my uncorked 75D is about as fast as your P85). I think Tesla might have really done you a solid if you end up with the same performance but with much much better battery cell chemistry, cooling, and pack design.

I would like to believe so too. I am happy with the range now. will tell if the supercharging performance as well as the 0-60 time is as good . That's why I don't want to jump into conclusion saying this is a "lesser pack" when it might have been a much better pack. :)

Would seem weird to me if performance is the same at 350volts unless the fuse was always way oversized and they are just allowing more amperage.

Another angle here is, is this going to be the batterygate fix?

That is the million dollar question. Crossing one's fingers.

Neat. New battery pack design. I was sort of expecting this to happen sooner or later. I am guessing Tesla is trying to retire the older module design manufacturing equipment. It would make sense to standardize the remaining 18650 packs based on the 100 pack design. So this new 85kwh type pack must use the 14 of the 16 modules used on a 100kwh pack.

I believe the original type 85 packs from 2012 to 2015 were only 400VDC packs, even the early ones that maxed out at 90kw supercharging. At least from everyone that I have seen...
I also can't find any evidence of an 85kwh "A" pack at 350 VDC. I'm not even sure how Tesla would have created such a beast in 2012 without a completely different module design.
