Vertical photorealistic macro photo in an engine bay of an ordinary passenger car inside a repair shop. The top of a car battery covered in road dust, damp grime and wet streaks; the positive terminal clamp has crusty white and pale green corrosion buildup. A mechanic's finger in a black nitrile glove points at the corrosion. Hard side light from a work lamp, moisture droplets, physically accurate battery terminal geometry. No faces, no logos, no brand labels, no text, no lettering.
