Does anyone know ( or is knowledgeable about batteries enough to surmise ) if the Li battery in the refreshed Model S can be retrofitted to the older cars?

Model S Li 12V battery

Battery cells != scalable
If it requires active thermal management, which it will if they're using the same cells as the HV pack, then it will not be easily retrofittable. If it does not require active thermal management then it should be easily retrofittable, might need an adapter. Additionally if it is integrated into the main HV pack then it is not going to be a retrofittable product.
If the new 12V battery has a BMS then the charging profile from the HV battery would seem to be the last hurdle. I doubt they would change the battery group size simply because of the manufacturing cost to do so and integrating it into the HV battery seems equally unlikely due to the increased difficulty servicing it. It sure would be nice to be rid of the lead/ acid battery using a replacement blessed by the Mothership. Let’s hope it happens.

Why make a new thread when this one exists?
6.9 Ah and it says 99Wh. The model X 12v battery is 40Ah. That 5.7x more charge! (Amp-hours is charge. Watt-hours is energy. Long story.). Tesla must be managing the lithium version a lot better than they did the lead-acid.
1P4S means 1cell in parallel and 4 cells in series. It’s a 4 cell pack. But which cells? 2170s? Or someone else’s pouch cells?
No idea. It looks square-ish. Flat. Someone can scale the size from those bolts, which are most likely 10mm hex heads.
Seems tiny. I look forward to seeing more info about this.
