Hybrid battery health on older models
Toyota hybrids use nickel-metal hydride (NiMH) or lithium-ion battery packs depending on generation. Toyota's hybrid battery warranty covers 5 years or 100,000 miles (extended to 10 years on some UK models sold after 2020). Most UK Corolla and Yaris hybrids are well within this window. On older models, battery capacity can reduce over very high mileage, leading to reduced electric-only range. Check for any battery-related warning history in the MOT advisories.
