Model X battery degradation and used range
EV batteries lose capacity slowly. At the average rate measured across 22,700 EVs (2.3% a year), a 2016 Model X rated for 465 km would have roughly 368 km of range today.
Model X used range by model year
| Model year | Rated when new | Age (years) | At 1.5%/yr | At 2.3%/yr | At 3.0%/yr |
|---|---|---|---|---|---|
| 2016 | 465 km | 10 | 400 km | 368 km | 343 km |
| 2017 | 475 km | 9 | 415 km | 385 km | 361 km |
| 2018 | 475 km | 8 | 421 km | 394 km | 372 km |
| 2019 | 523 km | 7 | 470 km | 444 km | 423 km |
| 2020 | 565 km | 6 | 516 km | 491 km | 471 km |
| 2021 | 597 km | 5 | 554 km | 531 km | 513 km |
| 2022 | 560 km | 4 | 527 km | 510 km | 496 km |
| 2023 | 560 km | 3 | 535 km | 522 km | 511 km |
| 2024 | 539 km | 2 | 523 km | 514 km | 507 km |
| 2025 | 529 km | 1 | 521 km | 517 km | 513 km |
The three columns reflect how the car was charged. Telematics firm Geotab found about 1.5% a year for EVs that rarely use DC fast chargers, 2.3% on average, and around 3% for EVs that fast-charge heavily at high power. Rated range is the longest version for each model year.
Checking a used Model X
Ask the seller for a battery health or state-of-health report from a dealer or a battery-testing service, and check whether the original battery warranty still applies. A full charge that shows a much lower range estimate than this table, in mild weather, is worth questioning.
