I very nearly had an identical issue. I hit a rock with 102k miles on the car. With a $1k deductible insurance approved Tesla's estimate and a replacement battery was installed.
Frankly, I fully expected a new battery replacement. But I found out only after the install that Tesla replaced it with a remanufactured battery. And for the real kicker, the newly installed remanufactured replacement battery showed an 11% degradation from a new battery!
I was shocked. I called Tesla. They explained that yes, it was a remanufactured battery they used (they did not tell me beforehand). And that it was "their policy" to replace a damaged battery with a battery that delivered an equivalent amount of charge. I was floored. I most certainly would have chosen a new battery regardless of the cost. But because I found all this out only afterward I was left with very little recall.
The total cost of the repair was $11,333.80. It was $9,923.80 in parts, $1,410 in labor. The battery p/n was listed as "ASY,HVBAT,75KWH,AWD-RWD,1PH,RMN(1137375-01-K) for $9,000. I now learn the RMN in the part number refers to "remanufactured".
I have Tesla's repair invoice if interested.
The question I'd be interested in in a scenario such as this (and perhaps the OP's, as well) is how Tesla determines the degradation level of the old battery if the car electronics (specifically the charging system and the BMS) are non-functional?
Wouldn't shock me if they throw a dart and "estimate" old battery degradation based upon its age. In any case, count me among those who think Tesla ought to provide the option of a new pack for those willing to pay for it.
