What type of battery is in the 2023 Lexus RX 450h+?

  • The vehicle uses a high-voltage hybrid battery pack to enable electric driving and a separate 12V auxiliary battery for accessory and control systems.
  • The high-voltage pack in this plug‑in hybrid architecture is a lithium‑ion design, engineered to deliver energy density and efficient charge acceptance for EV driving.
  • The 12V auxiliary battery may be an AGM or comparable OEM-specified type depending on equipment; exact specification is confirmed by VIN and factory records.
  • For safety, performance, and warranty compliance, replacements should use OEM-approved batteries and be installed by certified technicians at a dealership.

What size battery is in the 2023 Lexus RX 450h+?

  • Battery 'size' is measured differently: the high-voltage battery is specified by energy capacity (kWh), while the 12V battery is specified by group size, cold cranking amps (CCA), and reserve capacity.
  • Exact sizes and specifications depend on vehicle options and build; Nalley Lexus Smyrna will verify the correct battery size and part number from your VIN to ensure precise replacement.
