2025 Toyota Highlander Hybrid Battery Type
Understanding the battery types in your 2025 Toyota Highlander Hybrid helps guide smart maintenance decisions. The vehicle uses a high-voltage hybrid traction battery pack to power electric assist and recapture energy through regenerative braking, plus a 12V auxiliary battery for conventional electronics. Chemistry for traction batteries can vary by build—Toyota uses robust hybrid chemistries chosen for longevity and thermal stability—while the 12V unit is typically lead-acid or AGM depending on factory options. Routine battery checks at the dealership assess both systems and identify issues like low charge acceptance, cell imbalance, or terminal corrosion. Our factory-trained technicians use OEM diagnostic equipment to read battery management system data, ensuring accurate health assessment and the correct replacement type when needed. Selecting dealership service provides immediate savings through precise diagnosis and avoidance of unnecessary parts, and long-term savings by preventing incorrect replacements that can shorten battery life.
