Comparing:
9V Battery
D Battery
A 9V battery (IEC designation 6LR61, commonly called PP3) is a rectangular battery measuring approximately 48.5mm x 26.5mm x 17.5mm with two snap terminals. Alkaline 9V cells output 9.0V nominal from six internal 1.5V cells in series, with typical capacity around 400-600 mAh.
A D battery (IEC designation LR20, ANSI 13A) measures 34.2mm in diameter and 61.5mm in length -- the largest common cylindrical primary cell. Alkaline D cells output 1.5V nominal, with typical capacity in the range of roughly 12,000 to 20,000 mAh depending on discharge rate.
