2023 Lexus NX 350h Battery Type

Understanding the battery types in your 2023 Lexus NX 350h is key to effective maintenance. The vehicle employs a 12‑volt auxiliary battery for accessories and control modules alongside a high-voltage hybrid traction battery that manages propulsion and regenerative charging. Each requires a distinct diagnostic and service approach. Routine battery checks identify chemistry-specific issues—such as reduced cell capacity or state-of-charge drift—that can impact hybrid efficiency and reliability. Nalley Lexus Roswell’s factory-trained technicians use OEM diagnostic tools to evaluate both systems accurately and determine the correct OEM replacement chemistry and configuration. Using genuine manufacturer parts assures compatibility with vehicle software and safety systems, preventing faults that can arise from incorrect aftermarket components. This attention to detail reduces long-term repair costs, maintains fuel efficiency, and protects the vehicle’s electrical architecture.
