Final IECEE-CMC Decision on Batteries
Final CMC decision (based on a vote):
• (Lithium Ion) Batteries tested to UL standard 1642 will be
accepted without additional testing until June 25, 2010.
• From June 26, 2010 until June 26, 2011, LI batteries tested to
the UL standard 1642 must be subjected to additional testing to
the identified differences between UL 1642 and IEC 62133.
• From June 27, 2011, batteries must be tested and certified to
IEC 62133 only.
p/16
IECEE-CMC Decision on BatteriesScope:
• Original CTL and CMC decisions covered Lithium Ion Batteries only and UL Standard 1642
• The CTL standards comparison covers only IEC 62133 and UL 1642
• The final CMC decision covers all batteries that are in the scope of IEC 62133, including– LI cells and battery packs– Ni cells and battery packs
• UL Standard 2054 - often used together with UL 1642 - is similar in scope to IEC 62133 for LI and Ni cells and batteries
p/17
IECEE-CMC Decision on BatteriesUL’s Position
• UL is committed to work closely with Battery and End-Product Manufacturers to find the most efficient approach to this transition
• UL is also very well positioned to provide industry feedback to the CB Scheme into the future review of this issue by the CB Scheme
p/18
IECEE-CMC Decision on BatteriesLatest updates:
• At a very recent IECEE meeting (Feb. 2010), the US Information Technology Industry Council (ITI), with UL’s support, presented a letter requesting more time for the transition to IEC 62133.
• It was pointed out that the IECEE has not provided to the industry the differences between IEC 62133 and UL 1642, as promised in the CMC meeting minutes
• The discussion resulted in a recommendation to the CMC to re-start the transition time when the official standards comparison is completed and released by CTL.

Interim Requirements
The scopes of IEC 62133 and UL 1642 and 2054 are not equivalent and therefore some of the tests not identical.
• We will now review additional requirements in IEC 62133 and compare them to UL requirements
• We will also briefly identify potential challenges during testing for those cells and battery packs that are already UL Recognized
For batteries (cells and battery packs) already Listed or Recognized by UL and submitted for additional testing to IEC 62133 during the transition period, UL will use the existing test data to minimize the need for retesting.

p/31
Future stage• The first edition of IEC 62133 published in 2002 has some
shortcomings identified by the test houses and manufacturers and it has not been widely used by the industry
• The second edition of IEC 62133 will address many issues with the first edition. This edition is currently at the stage of its third CD. However, due to controversies that still exist, it is not clear when this edition will be published
• UL plans to both provide input into the second edition of IEC 62133 and to harmonize the UL battery standards with it as soon as thestandard is published
• In the meantime, UL will start introducing some of the requirements of the IEC 62133 second edition into UL standards. This will ease the transition to the IEC based standard.
• UL standard Bulletin should be ready for review in the first or at the beginning of the second quarter this year.
p/32
In the meantime...• The CMC decision on the use of IEC 62133 is only applicable to
IECEE CB Test Certificates and Reports
• UL will continue applying UL standards for US Market until the new or updated standard is published
• SC 21A is having difficulty reaching consensus on IEC 62133
• TC 108 is undecided about the battery requirements for IT, Communication and Entertainment Equipment
• The IT industry prepared a letter to the IECEE requesting a substantial delay in implementation of IEC 62133 in the CB Scheme
• It is likely that the transition period will be extended

Meeting Agenda
p/34
In summary• You have heard about several changes with the IECEE CB Scheme regarding batteries. Now
the choice is up to you, the manufacturer.
• The decision to start additional testing or full retesting of the battery cells and battery packs for the IECEE should be based on the manufacturer’s marketing plans
• It is up to the manufacturers of battery cells and battery packs, and end-products, to make their own business decisions regarding the transition to the IEC battery standard – you have the timetable for implementation, which may change, but it is coming – we can help you plan
• UL will support your decisions. We took your input to IECEE and CMC before and we continue bringing your feedback to the IECEE for further discussion of this issue. We have done it at the recent meeting of PAC in collaboration with the ITI. We encourage you to provide input as well, directly to the IECEE.
• The current UL requirements have not changed, but may change depending on the final disposition of IEC 62133. In the meantime, your existing or future certifications to UL 1642 and UL 2054 can be used to reduce necessary testing to demonstrate compliance with IEC 62133 First Edition.
• As always, we are ready to provide an efficient testing and certification service for verifying compliance with the relevant global battery requirements including UL, IEC and others, fully leveraging the testing related to any previous or concurrent UL evaluations based on UL 1642 and UL 2054. Depending on your marketing plans we can help you set up the most time and cost effective approach to obtaining all necessary battery certifications.
