How often should I replace my Toyota Prius battery?

I've had my Toyota Prius for 5 years and I'm starting to experience decreased performance. How often should I replace my battery and are there any indicators that it's time for a replacement?

It is recommended to replace the battery in your Toyota Prius every 8 years or 100,000 miles. However, if you are experiencing decreased performance or receiving error messages, it may be time to replace it sooner.

To determine if your battery needs replacing, you can use a diagnostic tool or bring your vehicle to a Toyota dealership. They will be able to test your battery's health and provide the best course of action.

Maintenance and regular checkups can help extend the life of your Toyota Prius battery. Make sure to schedule routine maintenance inspections and follow the manufacturer's guidelines for battery care.
