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.
This fourth edition cancels and replaces the third edition published in 1997 and its Amendment 1 (2000). It constitutes a technical revision. The main modification concerns the introduction of new dimensions.
