How Long Do Lexus RX 450h Hybrid Batteries Last?
On average, a Lexus RX 450h hybrid battery lasts between 8–10 years or 100,000–150,000 miles. However, real-world results vary depending on:
- Climate – Hot weather (like California summers) can stress battery cells.
- Driving habits – Smooth, steady driving preserves battery life.
- Maintenance – A clean cooling fan and filter prevent overheating.
- Usage – Letting the car sit unused for long periods can damage cells.
For many RX 450h owners, battery replacement becomes necessary once the vehicle approaches the 10-year mark.
