2018 Lexus GS 450h Battery Type

The 2018 Lexus GS 450h relies on two complementary battery systems: a 12V auxiliary battery that supports accessories and control systems, and a high-voltage traction battery that powers the hybrid drive. Understanding the differences is important for proper care. Auxiliary batteries are typically lead‑acid or absorbed glass mat designs and are replaced like conventional car batteries; they’re critical for reliable starts and stable electrical performance. The traction battery is a dense rechargeable pack engineered to deliver sustained power and manage regenerative braking cycles—these packs require factory-calibrated diagnostics and careful handling. At Stevinson Lexus of Frederick our certified technicians use dedicated equipment to test battery health, state of charge, and hybrid system integrity. We stock OEM-equivalent 12V batteries and source proper hybrid components when needed; any traction battery work is performed under strict safety protocols and manufacturer guidelines.
