I bought a used battery and installed it. After attempting software upgrades I took the car to Tesla. They said the battery was incompatible and offered to install a rebuilt one for $20K.

I had not heard of this before as most forums and Tesla service documentation does not mention incompatibilities across the range of batteries from 60-85KWH.

Anyone know if the car, battery or both can be reprogrammed to work with this battery? Apparently the P and D require a different battery. This is news to me.

There's got to be a way to get around this.
