Where's the degradation?

2012 P85 #2446 here.

It's been exactly one year since I got my new (not reman) out of pocket pack from Tesla. 90 kWh corked to 85 kwh. Since day one 244 rated miles at 90% SoC. Same 244 today.

My question - No degradation because corked to 85 and any degradation is in the 5 kWh I don't see? Or no degradation because, well, no degradation?

How did your SC rates of charge compare after changing to the new battery?

I got my BMS-u029 alert requiring pack replacement 3 days after purchase of the car, so I have nothing to compare it with. That said currently 120ish kW max and 50 kW min.

Folks I've talked to who have a valid comparison state their new pack is 2x SC rate of charge from before.

Almost certainly no degradation, not the use of the hidden 5kWh. Your case makes a good argument for getting a new battery instead of a reman.

My new uncorked 90Kwh battery has shown degradation in the last 2 years. It has gone from 275 miles to 262 miles at 90% charge in the last 2 years. So I would say you are not seeing the degradation due to the corking. Just my opinion based on my sample of one.

My battery left the service center corked 100% was 275, about 2 weeks it got uncorked charged to 304, after 30,000 miles, and almost a year it charges to 288.
