How do I know when it's time to replace my Toyota Prius battery?

I'm worried about replacing my Toyota Prius battery. How can I tell when it's time to replace it?

The battery on a Toyota Prius typically lasts around 8-10 years. You can check the battery health by using a diagnostic tool or by taking it to a mechanic. If it's below 80% health, it's time to replace it.

Watch out for any warning lights on your dashboard, as they can indicate a problem with your battery. Also pay attention to how your car is performing - if it's struggling to start or has a significant decrease in fuel efficiency, it's likely time to replace the battery.

Don't wait too long to replace your battery - a dead battery can cause other electrical components to fail, resulting in a more expensive repair.
