  • Our dealership installs OEM-specified replacements and confirms the correct chemistry and specifications for both the hybrid pack and the auxiliary battery.
  • Warranty-covered battery work must be completed at a certified dealership to ensure proper parts, programming and coverage continuity.

What size battery is in the 2018 Toyota Prius c?

  • The high-voltage hybrid battery is a model-specific pack measured by voltage and module configuration; it is served as a complete pack replacement rather than a typical automotive group size.
  • The 12-volt auxiliary battery uses a standard automotive group size specified by Toyota; exact group sizing can vary by production options and region.
  • Our service advisors confirm the precise OEM part number and group size for your specific vehicle before ordering to ensure fit, performance and warranty compliance.
