ANSI battery nomenclature

Previous editions of the ANSI accepted acclimated a letter cipher to analyze the ambit of the cell. Since at the time there were alone carbon-zinc cells, no suffix belletrist or added characters was required. The arrangement was alien in the 1924 copy of the standard, with belletrist A through J assigned about in adjustment of accretion corpuscle volume, for beef about bogus at that time.6 By 1934, the arrangement had been continued and revised and now had 17 sizes alignment from NS at 7/16 inch bore by 3/4 inch height, through admeasurement J at 1¾ inches bore by 5 7/ 8 inches high, to the better accepted corpuscle which retained its old appellation of No. 6 and which was 2½ inches in bore and 6 inches high.

edit Admeasurement and appearance codes

4.5-Volt, D, C, AA, AAA, AAAA, A23, 9-Volt, CR2032 and LR44 cells.

The accepted copy of the accepted uses a after cipher to appearance the corpuscle size. Common annular corpuscle sizes are:

ANSI primary corpuscle sizes and agnate admeasurement designations Number

code Other name IEC size

13 D R20

14 C R14

15 AA R6

24 AAA R03

25 AAAA R8D425

Since these IEC and ANSI array standards accept been harmonized, for example, an R20 corpuscle will accept the aforementioned ambit as an ANSI 13 cell.

Flat cells, acclimated as apparatus of multi-cell batteries, accept an F prefix and a alternation of numbers to analyze sizes. Coin beef were assigned admeasurement codes in the 5000 range.

Secondary beef application systems H and K (nickel-metal hydride and nickel-iron sulfide) accept a abstracted alternation of admeasurement codes, but the beef are dimensionally changeable with primary cells.
