How to Choose Batteries | REI Expert Advice
Basically, the farther you get through the alphabet, the larger the battery (e.g. D is bigger than C). When you see a letter used more than once (eg. AA, AAA), the more times it''s used, the smaller the battery (eg. AAA is smaller than AA). Sizing for coin cell batteries (also called button cell batteries) works a little differently.
