What type of battery is in the 2021 Toyota RAV4 Hybrid?

  • Two systems: the RAV4 Hybrid uses a high-voltage hybrid traction battery that supports electric drive functions and a separate 12V accessory battery for electronics and control systems.
  • Hybrid chemistry: many Toyota hybrid traction packs use proven chemistries chosen for durability and thermal management; specific chemistry and design are matched to Toyota engineering standards.
  • 12V options: the accessory battery is typically a sealed, maintenance-free design (lead-acid or advanced AGM in some configurations); exact specification depends on production date and equipment.
  • Dealer confirmation: our factory-trained technicians will identify the precise OEM battery type for your exact VIN and provide the correct replacement and programming to preserve performance.
  • Warranty and parts: using OEM-specified battery types at our dealership helps ensure any warranty-covered repairs remain valid and perform as intended.
