My 2003 Prius has 150K miles and the engine light came on. I was told by the dealership that I needed a new hybrid battery and they quoted it would cost between 3 to 4 thousand dollars to replace. I just didn't have the money to fix it and couldn't go without a car. I did some online research to find out if it was possible to buy a used Prius battery. I found http://hybridbatteryrepair.net and called to get more. Joe was extremely professional and educated about the Prius and the replacement of the battery. He came to my house the very next day and I paid him $1,599 and he replaced my battery. He was on time, clean, and very organized. He was done in about 2 hours and he went with me on a test drive to make sure the car was running properly before he left. My friends and relatives all advised against paying someone I didn't know to work on my car so I remained skeptical and purposefully waited 6 months to make absolutely sure that his claims and work were worthy of my praise. I am happy to report that it has been 6 months and my Prius is running like new. I highly recommend this company if it has been proven that your hybrid battery needs replacing and you can't afford a new battery.
