Abstract

This part of IEC 61960 specifies performance tests, designations, markings, dimensions and other requirements for coin secondary lithium cells and batteries for portable applications, watches, and backup power supply such as memory backup applications. In particular, watch-specific requirements are specified in Annex A. This edition includes the following significant technical changes with respect to the previous edition: a) added an annex to standardize requirements for secondary lithium watch batteries; b) added new chemistries; c) added a table to standardize dimensions and size codes for secondary lithium watch batteries; d) modified marking requirements.
