I say that because in my experience, UL has required it in past Listing efforts of products with them. And, if this is a cell phone application, please note that the CTIA has recently imposed requirements for lithium batteries. Supporting this, from UL2054's scope: - These requirements cover portable primary (nonrechargeable) and secondary (rechargeable) batteries for use as power sources in products. These batteries consist of either a single electrochemical cell or two or more cells connected in series, parallel, or both, that convert chemical energy into electrical energy by chemical reaction. - These requirements are intended to reduce the risk of fire or explosion when batteries are used in a product. The proper use of these batteries in a particular application is dependent on their use in a complete product that complies with the requirements applicable to such a product. - These requirements are intended to cover batteries for general use and do not include the combination of the battery and the host product which are covered by requirements in the host product standard. - These requirements are also intended to reduce the risk of injury to persons due to fire or explosion when batteries are removed from a product to be transported, stored, or discarded. - These requirements do not cover the toxicity risk that results from the ingestion of a battery or its contents, nor the risk of injury to persons that occurs if a battery is cut open to provide access to its contents. The battery manufacturer would quite likely be already aware of all of this. They would be the one to approach for getting this work done. Also, in addition to what Brian stated about shipping, the US and international shipping authorities have specific testing and labeling requirements for lithium batteries or products containing lithium batteries. Testing involves the UN T1-T8 tests. IHTH.

In general, conformity to the applicable standard is always "necessary"; but not always 'required'. In any case, note that UL 1642 is scoped specifically for Li batteries In particular, 'it depends'. Is the charger and end-use installation a fire or shock hazard if a battery, dies a violent death ? Is there any normal or abnormal operating condition in the charger or the end-use install that could result in battery damage/explosion/fire ? Also, there are separate DOT requirements for the shipment of some types of Lithium batteries. luck, Brian From: [email protected] [mailto:[email protected]]On Behalf Of Gartman, Richard Sent: Wednesday, July 02, 2008 6:51 AM To: [email protected] Subject: RE: UL 2054 testing for lithium batteries I am looking for when UL 2054 testing is necessary for rechargeable lithium batteries? Required on cell phone batteries? Required on consumer electronic? All perspectives on rechargeable lithium batteries are welcome. Thank you W.
