Comparing:
9V Battery
AA 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 standard AA battery measures 14.5mm in diameter and 50.5mm in length. Primary Alkaline cells output 1.5V, NiMH rechargeable cells output 1.2V. Inserting a 3.6V 14500 Li-ion cell into 1.5V AA devices destroys the circuit.
