Duracell (tm) makes a cell which is larger than AA, smaller than C, 
with roughly twice the capacity of AA.  It is available in a 3-cell 
battery (Duracell # MN1203) commonly available in Europe but rarely 
seen in the U.S.

Old battery sizes die because of unpopularity or obsolescence. For 
example, The #6 dry cell is still available, but in the early 1900's 
there were smaller #4 dry cells, and giant #8 dry cells (about the 
size of a Quaker Oats box). The number refers to size; #6 dry cells 
are 6" tall.
