It may just be selective memory on my part, but the battery charge indicator on my 2009 Prius seems to be staying full green most of the time. I thought in the past it was mainly in the blue, unless I had descended a long hill. Also, when I am accelerating going up a steep hill, the MFD shows the battery charging even though it is 8 bars. Is this normal? I have had it checked by the dealer and they say everything is normal.
