Button cells are available in the same size under different manufacturer specific names. 1.5V cells are available as alkaline batteries or as more expensive but more durable silver oxide batteries. The alkaline and silver oxide batteries used to have different names.
How tall is a AA battery?
An AA cell measures 49.2–50.5 mm (1.94–1.99 in) in length, including the button terminal—and 13.5–14.5 mm (0.53–0.57 in) in diameter. The positive terminal button should be a minimum 1 mm high and a maximum 5.5 mm in diameter, the flat negative terminal should be a minimum diameter of 7 mm.
Are all AAA batteries the same?

Is there a single a battery?
A single A has a single cell of 1.2 to 1.5 volts(3.0 or 3.6 for lithum). The battery you have is a stack of three button cells. the size of one of these cells often being referred to as a #1 or R50. The capacity should be far greater than using 3 of the commmon R44 button cells, but less than the 123A, AA combination.
