Used Tesla Model S Prices Have Fallen Dramatically, but Their Batteries Are Holding up Great

Used Tesla Model S prices have dropped sharply on the secondary market, but a closer look at battery degradation data suggests the long-term outlook for these vehicles may be more positive than their sale prices indicate.

What Happened

InsideEVs analyzed real-world battery degradation data from older Model S vehicles, examining how these cars have held up over time despite significant shifts in used car pricing. The findings show that even high-mileage examples of Tesla's flagship sedan are retaining a larger portion of their original battery capacity than many buyers may expect.

Why It Matters

For potential buyers considering a used Model S, battery health is often the primary concern when evaluating whether an older EV represents good value. These degradation figures matter because a replacement or repair could cost thousands of dollars, making strong battery retention a key indicator of long-term ownership costs. Meanwhile, dramatically lower purchase prices mean more buyers can access Tesla's premium segment at accessible price points.

The Bottom Line

Used Model S values have fallen considerably, but the underlying data suggests these vehicles remain mechanically viable for owners willing to monitor range and plan charging accordingly. Battery longevity appears solid enough that concerns about pack health may be less warranted than used car prices might imply.
