My GenII Prius Battery warning lights finally went on at $198,00 miles so called the stealerships only to be quoted $3,000 to $4,000. I shopped around and found Joe who installed a refurbished one for $899. They even drove to where I am instead of having me drive 30+ miles all the way to Sherman Oaks where they are based. The change was quick and 5,000 miles later I am still running on the battery good as new.
