respectively. For reference, the ANSI letter codes for the electrochemical systems are also listed in
Table 4.2c. The ANSI nomenclature system does not use a code to designate shape.
Nomenclature for existing batteries was grandfathered. Examples of the nomenclature for some
of these primary cells and batteries are shown in Table 4.3a. Examples of the IEC nomenclature
system for primary batteries are shown in Table 4.3b.
