Hi all, I "accidentally" purchased a 2006 Prius in December 2017 at an auction. It threw (I know that's why the previous owner got rid of it) the P0AA6 code, and after researching. I decided to eliminate some suspected causes; so I purchased a new Duracell battery, and replaced the inverter coolant pump. The code came back, and I came to the unfortunate realization that the traction battery needs to be replaced. I am selling the Optima battery that came with the car. I believe the battery was manufactured in August of 2017 (if I am deciphering the bar code correctly). Autozone tested the battery and said it's a good battery.The battery is for cars with smart key. I am selling for $100.
