When should I replace my Toyota Prius battery?

I have a Toyota Prius and I am wondering when I should consider replacing the battery. What are the signs that the battery's performance is declining and when is the best time to get it replaced?

It is highly recommended to replace your Toyota Prius battery after 100,000 miles or 8-10 years of use.

If you are experiencing a decline in performance, such as reduced fuel efficiency or difficulty starting the car, it may be time to replace your battery.

Regularly checking your battery's voltage and ensuring it is within the recommended range can also help determine when to replace it.
