Lexus ES 300h Hybrid Battery Replacement
The Lexus ES 300h executive sedan shares its hybrid drivetrain and battery architecture with the Toyota Camry Hybrid, using a 244.8V NiMH battery pack. ES 300h owners in Kelowna and the Okanagan are typically long-distance commuters or executive drivers who have accumulated significant mileage. When the battery begins to fail, the contrast between the ES 300h's normally smooth power delivery and the degraded hybrid performance is particularly noticeable — and dealer quotes for replacement are often a shock.

Lexus ES 300h Battery — Common Questions
Specific to this vehicle. Call us for anything not covered here.
Both the ES 300h and the later ES 400h use NiMH battery packs, but the ES 400h uses a slightly larger, more powerful configuration. Our pricing covers both — call to confirm your exact model year and spec when booking.
The Lexus ES engine is extremely durable and regularly reaches 300,000–400,000 km. At 180,000 km the engine and transmission are barely broken in. A $1,799 battery replacement that restores full performance and fuel economy is almost always the right financial decision compared to a vehicle purchase.
