The broken lines shown in the drawings show portions of the battery housing cover which form no part of the claimed design.
The shade lines in the Figures show contour and not surface ornamentation.
It should be noted that references to relative positions (e.g., “left,” “right,” “front,” and “rear”) in this description are merely used to identify various elements as are oriented in the Figures. It should be recognized that the orientation of particular components may vary greatly depending on the application in which they are used.
