2018 Acura NSX Battery Type

The 2018 Acura NSX uses a sophisticated hybrid architecture that pairs a high-voltage lithium-ion battery pack with a dedicated 12V auxiliary battery to manage electronics, control modules and accessory loads. The hybrid pack supplies energy to the electric motors and regenerative systems, while the 12V unit supports starting circuits and onboard electronics. Proper maintenance must address both systems because symptoms in one can affect the other. Nalley Acura inspects battery health using OEM diagnostic software to measure state of charge, cell balance, and system faults. We recommend OEM-specified replacement components when needed, because aftermarket substitutes can present compatibility risks and may not meet Acura’s tolerances. Our technicians are trained to safely service high-voltage components and to document work that preserves factory warranties. Choosing dealership service ensures the correct battery chemistry and form factor is installed and verified, giving you predictable performance, reliable start-up, and full adherence to manufacturer standards. Contact Nalley Acura’s service department for a comprehensive battery type review and diagnostic appointment.
