Round button batteries aswell backpack two-digit admeasurement codes such as R44, see the button array table for archetypal dimensions. Added round, flat, and aboveboard sizes accept been connected but are acclimated mostly for apparatus of multi-cell batteries.

Several sizes of button and bread cells. Some are acrid and others argent oxide. 2 9V batteries were added as a admeasurement comparison.

The afterward is a fractional account of IEC accepted recommended bore and acme codes for annular cells:

edit Modifiers

After the amalgamation admeasurement code(s), added belletrist may optionally arise in the blazon appellation to announce the electrolyte used:

S: sodium hydroxide electrolyte

P: potassium hydroxide electrolyte

no letter: amoebic electrolyte

Terminal styles and variants of the aforementioned array can be appointed with the belletrist X or Y. Performance levels may aswell be appointed with a C, P, S, CF, HH, or HB or added letter suffixes. Rechargeable types may accept a suffix L, M, or H to baptize low, average or top acquittal appraisement designs. An added letter "W" states that this array complies with all the requirements of the IEC 60086-3 accepted for watch batteries.
