2. 49 CFR and
Lithium battery: cells and batteries containing lithium in any form, including lithium polymer and lithium ion cells and batteries. It includes PRIMARY and RECHARGEABLE batteries
Two shipping names:
UN 3090: Lithium Batteries
UN 3091: Lithium Batteries Contained In Equipment or Lithium Batteries Packed With equipment

3. Recent DOT Activities on Lithium Batteries
April 2, HM-224C, Notice of proposed rulemaking
December 15, HM-224E, Interim final rule

4. Proposed Revisions of 49CFR (HM-224C)
UN Model Regulations revised Li Bat provisions in 2000 which were implemented in ICAO, IMDG regulations in 2003**
Notice of proposed rulemaking, HM-224C (April 2, 2002) intended to incorporate the 2000 UN revisions
**: LAX incident of April 28, 1999
involving Li batteries

5. Proposed Revisions of HM-224C
1. Changes to test methods
2. Revisions to exceptions for
small batteries
3. Eliminate the 5 g for cell and 25
g for battery exception
4. Exceptions for aircraft
passengers and crew (175.10)

6. Proposed revisions in HM-224--- Continued
1. Changes to test methods:
Adopting the revised UN test requirements described in Section 38.3 of the UN Manual of Tests and criteria, Rev. 4
6 tests (T.1 to T.6 in Rev. 3) to 8 tests (T.1 to T.8 in Rev.4)

7. Proposed Revisions in HM-224C--- Continued
2. Changes for excepted small size
batteries:
Limit of lithium content: 1.0 g for cells (1.5 g for lithium ion), 2.0 g for batteries (8.0 g for lithium ion)
Must meet the testing requirements
Each package contains more than 24 cells or 12 batteries be: (i) marked, (ii) accompanied with a document, (iii) limited to 30 Kg (gross wt.), and (iv) pass 1.2 meter drop test

8. Proposed Revisions in HM-224C--- Continued
3. Eliminate (c)(49 CFR,
Oct.1, 2004 edition)---
exception for 5 g cells and 25 g
batteries

9. Proposed Revisions in HM-224C--- Continued
4. Changes to (air regulations):
Allow passengers and crew to carry consumer electronic devices containing lithium (lithium ion) cells or batteries for personal use on board an aircraft
Allow spare battery to be carried in carry-on baggage: 1 battery with not more than 2 g lithium content; up to 2 lithium ion batteries 8 to 25 g equivalent lithium content

10. Proposed Revisions in HM-224E
Prohibit transportation of primary lithium cells and batteries, as cargo, aboard passenger aircraft
Packages containing lithium cells and batteries that are excepted by (b) or (c) can only be transported by cargo-only aircraft and the package has to be marked with “PRIMARY LITHIUM BATTERYIES—FORBIDDEN FOR TRANSPORT ABOARD PASSENGER AIRCRAFT”

11. Proposed Revisions in HM-224E---Continued
Limit the quantity of secondary lithium cells and batteries aboard passenger aircraft to 5 Kg (gross weight) per package
Primary cells and batteries excepted by (b) or (c) contained or packed with equipment are allowed on board passenger aircraft but limited to 5 Kg (gross weight) per package

12. Proposed Revisions in HM-224E---Continued
Secondary lithium cells and batteries are allowed on board passenger aircraft but limited to 5 Kg (gross weight) per package

13. Proposed Revisions in HM-224E---Continued
Lithium cells (5 g Li content) and batteries (25 g Li content) installed in or as spare part for personal use electronic devices or medical devices are allowed in carry-on or checked baggage aboard passenger aircraft
This rule (HM-224E) applies to both domestic and foreign transport aboard passenger aircraft
