Must lithium ion batteries be tested pursuant to the UN Manual of Tests and Criteria?
Starting in 2003, new testing requirements took effect that require testing for all lithium ion cells and batteries shipped internationally. In the U.S., UN testing requirements for small, consumer-size lithium ion cells and batteries went into effect on October 1, 2009. • How is the “equivalent lithium content” for a lithium ion cell and battery determined? Equivalent lithium content means, for a lithium ion cell, the product of the rated capacity, in ampere-hours of a lithium ion cell times 0.3. The total equivalent lithium content is expressed in grams (g). The equivalent lithium content of a battery equals the sum of the grams (g) of equivalent lithium content contained in the component cells of the battery. Example: A lithium ion cell in a laptop battery pack may have a rated capacity of 2.2 ampere-hours. Applying the conversion factor of 0.3, a battery pack with 9 of these cells contains 5.94 grams of equivalent lithium content.
