How often should I replace the batteries on my Toyota Prius?

I've had my Toyota Prius for a few years now and I'm wondering how often I should replace the battery. I've heard different opinions from different people. What's your advice?

There is no set time frame for replacing the battery on a Toyota Prius. It depends on your driving habits and the overall condition of the battery. Some people have reported needing to replace their battery after 8-10 years, while others have gone over 15 years without replacing it. It's important to monitor your battery health and replace it when necessary.

It's always better to be proactive and replace your battery before it completely dies. If you notice a decrease in performance or difficulty starting your vehicle, it's probably time for a new battery. Keep in mind that a well-maintained Prius battery can last up to 15 years or more.

I've found that replacing the battery every 10 years or so is a good rule of thumb. This ensures that you're not caught off guard with a dead battery, but also not replacing it prematurely and wasting money.
