Model 3 SR+ LFP Battery Range, Degradation, etc Discussion

What SOC had it mostly been at ?
What kind of climate? Parked outside or garage?

In average temperatures we would expect around 10% (10-11%) calendar aging if the SOC was mostly 70-90%.

I usually charge it to 90%, and it stays between 40% and 90% most of the time. There was one time where it dropped to 1%. Charged a few times a year to 90% at supercharger.

Average temperature, parked inside garage always

Your car is doing great and it sounds like the cool temperatures are doing it good. You can continue to get good results by keeping it below 55% most of the time, which sounds like it would be easy for you to accomplish. If you barely use it you could consider even lower but given the long periods where you leave the car and cannot charge it, it might make sense to just leave it at 60% initially or whatever.

It sounds like he chargers to 90% then parks it where there is no L2 charger available (apartment complex for example) for months on end. That’s not suitable for low SOC due to vampire drain.

Considering how he is treating the battery (high SOC storage, although temp is good) it has held up extremely well.

Yeah sounded like he could get away with 60%.

For interest, 108 cells is confirmed for the 60.5kWh LFP (M3 RWD, Aug 2022, MIC, 4%SOC).
