IEC 60254-2:2000 pdf download.Lead-acid traction batteries – Part 2: Dimensions of cells and terminals and marking of polarity on cells
1 General
1 .1 Scope and object
This part of IEC 60254 is applicable to lead-acid traction batteries used as power sources for
electric propulsion.
The object of the present standard is to specify
– the maximum external (overall) dimensions of traction battery cells, that is, the width, the height and the length;
– the form of the marking of traction battery cell polarity and dimensions of corresponding symbols;
– the basic dimensions of some commonly used traction battery terminals designed to connect output cables to the battery;
– the dimensions of cells commonly used in Asia and North America.
1 .2 Normative references
The following normative documents contain provisions which, through reference in this text,
constitute provisions of this part of IEC 60254. For dated references, subsequent amendments
to, or revisions of, any of these publications do not apply. However, parties to agreements
based on this part of IEC 60254 are encouraged to investigate the possibility of applying the
most recent editions of the normative documents indicated below. For undated references, the
latest edition of the normative document referred to applies. Members of IEC and ISO maintain
registers of currently valid International Standards.

2.2.2 The dimensions of traction battery cells in accordance with this standard shall
correspond to those of table 1 .
2.3 Cell range prevalent in Asia 1 )
The dimensions of traction battery cells in this range are given in table 2.
2.4 Cell range prevalent in North America 2)
The dimensions of traction battery cells in this range are given in table 3. Width and length only
are specified.
3 Marking of polarity on traction battery cells and dimensions of
corresponding symbols
3.1 General provisions for marking of cell polarity
To comply with this standard, traction battery cells shall carry the marking of polarity, at least of
the positive terminal.
3.2 Form of marking
The marking shall take the form of the symbol +, indented or in relief, on the lid adjacent to the
positive terminal.
If the negative terminal is also marked, the marking shall take the form of the symbol –,
indented or in relief, on the lid adjacent to the negative terminal.
3.3 Symbols used for marking and their dimensions
Symbols used for the marking of the polarity shall be in accordance with future IEC 6041 7-1 .
The marking of the positive terminal shall be in accordance with the symbol 5005-a: Plus,
positive polarity.The eventual marking of the negative terminal shall be in accordance with the symbol 5006-a:Minus, negative polarity.The actual value of dimension ” a ” of these symbols shall be equal to or greater than 5 mm.
NOTE A dimension ” a ” of 5 mm corresponds to a total length of each arm of the symbol equal to 6 mm.
4 Basic dimensions of traction battery terminals
4.1 General provisions for dimensions of battery terminals
This standard gives only basic dimensions of standardized types of battery end terminals
necessary to ensure interchangeability. The use of other forms of terminal is not precluded.4.2 Conical traction battery terminals
The traction battery terminals shall be chosen from the three types listed in figure 1 , based
upon the cross-sectional area of cable used.
4.3 Bolted traction battery terminals
The traction battery cable ends for bolted terminals shall be chosen from the four types listed in
figure 2, based upon the cross-sectional area of cable used.
NOTE For smaller size connections, reference should be made to the dimensions of terminals shown in IEC 60095-2.
