Test conditions in the standard must consider and therefore specify the following:
Cell (battery) temperature
Discharge rate (or load resistance)
Discharge termination criteria (typically loaded voltage)
Discharge duty cycle
If rechargeable, charge rate, termination criteria (either time or feedback of cell response) and
other conditions of charge
Humidity and other conditions of storage may also be required.

4.7 MARKINGS

Markings on both primary and secondary (rechargeable) batteries may consist of some or all of
the printed information given in Table 4.7 in addition to the form and dimension nomenclature
discussed.

4.8 CROSS-REFERENCES OF ANSI IEC BATTERY STANDARDS

Table 4.8 lists some of the more popular ANSI battery standards and cross-references to the interna-
tional standard publications for primary and secondary batteries.

4.9 LISTING OF IEC STANDARD ROUND PRIMARY BATTERIES

The eleventh edition of IEC 60086-2 for primary batteries lists over one hundred types with dimen-
sional, polarity, voltage, and electrochemical requirements. The second edition of IEC 61951-1 for
rechargeable nickel-cadmium cells (batteries) lists 25 sizes with diameter and height specified in
chart form. Several rechargeable nickel-cadmium and nickel-metal hydride batteries are also pack-
aged to be interchangeable with the popular sizes in the primary replacement market. These have
