Description / Abstract:

This publication applies to portable rechargeable, or secondary, cells and batteries1 based on the following electrochemical systems:

a) Nickel-cadmium

b) Nickel-metal hydride

c) Lithium-ion including lithium ion polymer

Section 1 of this standard contains general information and all standardized performance and mechanical tests upon which all the specifications in Section 2 are based.

Section 2 specification sheets list those tests and requirements described herein that are required for each battery. Not all tests in Section 1 are necessarily required on every specification sheet.

Part 2 of this standard describes all safety tests and requirements.


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 standard performance tests and provide guidance for their assessment; and,

d) To provide guidance to consumers, manufacturers, designers, and other end users.

This is achieved by specifying designations, dimensions, polarity, terminals, markings, test conditions, and procedures.
