How often should the battery on my Toyota Prius be replaced?

I am thinking about purchasing a used Toyota Prius, but I am concerned about the longevity of the battery. How frequently should the battery be replaced? Will it be costly and labor-intensive?

Typically, a Toyota Prius battery will last for about 8 to 10 years. However, it largely depends on driving habits and environmental factors such as temperature. It's best to have it checked by a certified technician every few years to determine its health and when it may need to be replaced.

Fortunately, Toyota offers a warranty for the battery of up to 10 years or 150,000 miles. So if you purchase a used Prius with a low mileage and within the warranty period, you shouldn't have to worry about replacing the battery anytime soon.

In case the battery does need to be replaced, it can be costly, ranging from $2,000 to $4,000. However, there are third-party companies that offer refurbished batteries for a lower cost. Just make sure to do your research and choose a reputable company.
