The question is; over time how much power is the battery producing compared to when new? A Toyota Prius gets 50 mpg when it is new, but as the battery loses capacity, what is the fuel mileage in year 5? Its not like the battery that starts the car, you know it is finished when it won't start the car. In year 5, the Prius might be doing 35 mpg, but does anyone notice?
