Battery and warranty

  • Chemistry: NCA (Panasonic 2170L NCA).
  • Battery and drive unit warranty: 8 years or 100,000 miles, with at least 70% of the battery's capacity guaranteed.
  • VIN, 7th character: F = LFP (Shanghai-built cars, and all Model 3s from 2024). E = nickel-based — but on Fremont-built cars before 2024, E just means “electric”, so use the touchscreen check.
  • VIN, 11th character: plant — C = Shanghai, F = Fremont. VINs starting LRW are Shanghai-built, 5YJ Fremont-built.
  • UK cars: 2019–20 Model 3s came from Fremont (VIN 5YJ, nickel-based); from late 2020 UK cars came from Shanghai, with LFP on Standard Range Plus / Rear-Wheel Drive.
