Tesla Calendar Aging: LFP vs NMC Battery Truth
Most EV owners assume a parked Tesla is a safe Tesla. It is not. Even while your car sits in the garage a slow chemical process is quietly reducing your battery capacity every single day. LFP and NMC handle this process very differently and understanding which one ages faster on the calendar could change how you buy, manage, and store your next Tesla.
In this video:
What the SEI layer is and why it grows whether you drive or not
Why NMC loses 2% to 4% capacity per year from calendar aging alone
Why LFP loses roughly half that at equivalent temperatures
How every 10 degree Celsius increase doubles your degradation rate
The optimal storage state of charge for both chemistries during extended periods
Plus real community data showing calendar aging in actual owner numbers.
