I had a Prius II battery reconditioned/refurbished by Auto Trends. They did it in 3 days and thoroughly tested (put 90 miles on the car!) it to make sure everything was right. The price was less than they first quoted, so I was happy about that. They listed some other things that needed doing, and answered my questions about these things. I had them take care of a few more things and did some myself because it seemed too expensive to have them do the easy things (air filter, cabin filter, spark plugs).
