Battery and warranty

  • Chemistry: NCA (Panasonic 18650 NCA).
  • Battery and drive unit warranty: 8 years or 150,000 miles, with at least 70% of the battery's capacity guaranteed.
  • 2012–13 cars: the VIN's 8th character shows the pack — C = 40 kWh tier, G = 60 kWh tier, N = 85 kWh tier, P = 85 kWh tier with the Performance motor. (2014–15 VINs only say standard or high capacity in the 7th character.)
  • Badges can mislead: 2016–17 cars badged 60/60D (and some 70/70D) use a 75 kWh pack limited by software. If yours has been unlocked, choose the 75 version.
  • Older 85 kWh packs: a 2019 software update capped range on about 1,700 cars; if your range dropped suddenly in 2019, that may be software rather than wear.

The last Model S and Model X were built at Fremont on 10 May 2026; 2026 was the final model year. (Wikipedia gives 13 May; contemporary reports say 10 May.)
