How Long Does It Take To Charge A Tesla?

The net and total capacities of an EV battery are different. There is always a 3-5% buffer remaining

since the manufacturer doesn't let it totally empty or charge in order to use it most efficiently and prolong its lifespan

This indicates that while the overall battery capacity is more than the net

you can only use the net area. To minimise battery deterioration

 it is generally advised for EV users to maintain charging levels between 20% and 80%. The new lithium iron phosphate (LFP) battery cells,

 however, which could be frequently completely charged up to 100%, 

were introduced by Tesla for the most recent 2022 models

The owner can pick 100% without harming the battery if the limit is explicitly established.
