2021 Lexus RX 450h Battery Type

The 2021 Lexus RX 450h is a hybrid crossover that uses a dual-battery approach: a high-voltage traction battery that supports electric drive functions and a conventional 12‑volt battery that powers lights, infotainment, and control modules.

Our Park Place Lexus technicians in Plano inspect both systems during routine maintenance to detect weak cells, poor charging behavior, or parasitic drains early. We explain the pros and cons of available replacement choices without industry jargon and recommend OEM-equivalent components whenever possible. That approach preserves fuel economy, maintains hybrid efficiency, and protects factory warranties.
