AA AAA AAAA

a close-up of a package of AA batteries, with the camera panning across the packaging to reveal the text "AA4" and "ALKALINE" in red and gray lettering on a white background. The camera then moves to show a package of AAA batteries, also labeled "ALKALINE" with a red and white design, before panning back to the AA package. The camera movement is slightly shaky, and the focus shifts between the two packages.
