if you charge at home every night, and don't commute across state lines every single day, no need to charge that high. Charge to 80 and only to 100 when taking a long trip.I was wondering how much % I should charge my SR.
It is downgraded from SR+, so 100% in SR now is actually just about 90% to the original.
Will charging 100% in this SR every time be ok?
I charge to 100% nightly on my SR. It is supposed to be top locked which would mean that is fine to do and would be like charing it to 90% ish based on the batteries actual capacity. There have been plenty of times we had a decent amount of stuff to do or went to a park a little ways away and were close on available range. I just keep it charged to 100% in case we need the range.I was wondering how much % I should charge my SR.

I don't. But top lock is how they have traditionally done it on previous vehicles. I'd change my charging behavior if Tesla or someone provides differing information.How do you know it's not "bottom locked"?

Previously posted comments by SR owners who charge to 100% state, that regenerative braking is not limited at 100%, like it normally is for all non software-locked models. This heavily implies the SR is top locked, and not bottom locked.
Bottom locking might also interfere with the BMS re-calibrating or re-balancing the batteries, which requires low charge levels to work.

Yes, Tesla Service has access to that sort of information but Tesla owners do not. Which makes sense from Tesla’s point of view: they don’t want to deal with obsessive owners pestering them with questions about the exact state of charge of individual cells or groups of cells.There is got to be a way to get cell voltage read outs from the car in some debug mode or something?
apart from mswlogo noone here really gets the OPs question.

I will test this tomorrow morning.Previously posted comments by SR owners who charge to 100% state, that regenerative braking is not limited at 100%, like it normally is for all non software-locked models. This heavily implies the SR is top locked, and not bottom locked.

There's also an interesting paper posted in the battery/charging section of the forum, which states that low charge levels are necessary to self heal cracks that form when nickel cathodes are under strain from being charged to high levels. This applies to high nickel content (above 0.8 ratio) cathodes, which the Model 3 probably does use.
Regen is disabled/limited at high charges.What happens if you charge to 100%, and then regen down a tall mountain?
