AA

The AA battery (or double-A battery) is the North American name for a single cell cylindrical battery that 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 IEC 60086 system calls the size "R6", ANSI C18 calls it "15", and it is named "UM-3" by JIS of Japan. Several different battery technologies are available in this form factor, including: Zinc–carbon, Alkaline, Li-FeS2, Li-ion, LiFePO4, NiCd, NiMH, and NiZn.

Aa

"Aa" is the symbol which became the shortened version to mean 'Aaron'; it must be mentioned that the honor & wherewithal, yes, the absolute due credit go to non other than 'Aaron Ludtke' of Washington state. Any man with the name 'Aaron' &/or friends of people named 'Aaron' often use the 'Aa' when engaged in communicating via text mail.

Aaron was surprised to find that 'Aa' had not been recorded as an abbreviation of his name; at least in the Urban Dictionary.
