    I finally got a response from Tesla on the 'can I charge to 100% all the time with a 60kw pack?' question. Unfortunately the standard restrictions and advice applies, that is charging to 100% all the time will result in faster degradation of the battery.

    Even though the new 60kw version of the Model S is in fact a 75kw battery pack, the extra cells are completely cut off from receiving any charge until the OTA upgrade is taken.

    Was the response from a local store employee or tesla corporate? All other info I've heard since the 60 was reintroduced is contrary to that, saying the entire 75 will charge but only 60 available for driving discharge.

    It was from my delivery experience specialist. It would be nice to hear either way from Elon.

    My understanding is that the 60kWh battery can be charged to 100% all the time since in effect it is indeed charging the 75kWh total capacity of the battery to 80%.

    That is the most logical theory but I dont want to risk damaging the battery without any official word on the issue, and the only official word I have so far is from my local service center. Hopefully it will get clarified.

    A test would be to charge to 100% and see if the regen brake line shows up. If in reality it is charged to 90% and its not too cold, you should have full reg braking available. If the battery is truly 100% full, regen braking would be limited.
    Or find another 75 to time a supercharge recharge to 80% and the 60 to 100% and see if the time is comparable

    Yeah you'd think that it has to work upto 100 as the cells aren't 'dead' until the software wakes them up.

    60 is 80% of 75, not 90%.

    Still a question back and forth on TMC. Seems to be 100% charge is OK. IMHO I think Tesla does not answer this question clearly because the truth would cut into 75KWH sales.

    Yes. The new 60kwh Model S is OK to charge to 100% because the screen charge meter is scaled down to reflect a real charge rate of 80% of the physical 75kWh battery. You're effectively charging the battery to 80% even though the charge rate meter is displaying 100%

    If someone pays to unlock the rest of the battery the software recalibrates the charge screen display and the charging system to allow full access to the 75kWh pack.

    Another argument that this might be wrong, is that batteries have a self-discharge rate. If you don't charge them ever, the charge leaks, and eventually the battery gets to a point where it is physically damaged, and can't be used at all.

    Thank you kindly.

    Quick question on this subject, but if you have a 60 and you unlock the car to 75 after market via the OTA update, would Tesla install 75 tags on the car for free or would you have to pay for that? Or do they even do it at all?

    I think I heard that badging could be updated at a service center, but there was a comment made earlier this year that the downside to the OTA battery upgrade was the VIN/title would be tied to the lesser battery size. So probably not an issue for the owner driving the car, if anything maybe getting a deal on insurance (but flip side also could be if totaled, could miss out of the extra value), but when the vehicle is sold, it would technically be listed as a 60 and not a 75 and that could not be revised once the car leaves the factory. (much like my '67 mustang with a 302 but it's VIN will always say it has a 289)

    That all makes sense. If you buy a 75 from the factory does it come with a 75 badge and show 75 on the title?

    For the price charged the least they could do is give the 75 badge w/o an extra charge

    This subject has been on my mind. Good to know that the 60kw can be charged to 100% and it would be like owning the 75kw but at 80%.
    I wonder if you save a little on insurance since the 60kw would be less expensive and you later upgrade to the 75kw and still get rated by insurance as the 60kw. Bummer about the totaling of a car though. Perhaps proof of the upgrade can be submitted and accepted in order to get the real value out. Can we have our cake and eat it too?
