Yaris Hybrid Battery — NiMH Care Guide
Yaris Hybrid uses a Nickel-Metal Hydride (NiMH) traction battery — same proven chemistry as Prius hybrid. Toyota's warranty covers the hybrid battery for 8 years or 160,000 km. NiMH batteries tolerate Malaysian heat better than lithium-ion. Signs of degradation: reduced EV-mode time, fuel economy drops 20–30% vs when new, battery charge depletes quickly. The battery does not need replacement at fixed intervals — it is changed on condition. A health check with Toyota's diagnostic tool confirms state of health (SOH).
