ANSI C18.3M-1-2005 pdf download American National Standard for Portable Lithium Primary Cells and Batteries— General and Specifications
1.1 Scope and purpose
1.1.1 Scope
This standard applies to portable lithium primary cells and batteries. This edition includes the following electrochemical systems:
a) Lithium/carbon monofluoride;
b) Lithium/manganese dioxide;
c) Lithium/iron disulfide.
1.1.2 Purpose
The purpose of this publication is:
a) To ensure the electrical and physical interchangeability of products from different manufacturers;
b) To minimize proliferation of cell and battery types;
c) To define a standard of performance and provide guidance for its assessment;
d) To provide guidance to consumers, manufacturers, and designers.
This is achieved by specifying nomenclature, dimensions, polarity, terminals, marking, test conditions, and procedures.
1.2 Normative references
The following standards contain provisions which, through reference in this text, constitute provisions of this American National Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this American National Standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.

ANSI C18.3, Part 2-2003, For Portable Lithium Primary Cells and Batteries–Safety Standard 1.3 Definitions
1.3.1 application test: A test which simulates the actual use of a battery in a specific application.
1.3.2 battery: One or more cells, including case, terminals, and markings.
1.3.3 battery, coin: Small round battery, in which the overall height is less than the diameter.
1.3.4 battery, portable: A battery that is easily carried.
1.3.5 battery, primary lithium: A battery that is not designed to be charged and has metallic lithium or lithium alloy as its anode.
1.3.6 battery, prismatic: A battery with non-round geometry.
1.3.7 battery, round: Cylindrical battery, the overall height of which is greater than or equal to its diameter.
1.3.8 capacity: Quantity of electricity, usually expressed in Ampere-hours (Ah), which a battery can deliver under specified discharge conditions.
