FAQ

1. How to identify battery types and their classification

1.1        What types of batteries are classified as dangerous goods?
There are basically 4 battery families, based on their reference chemical element:
·       Lithium based
·       Lead based
·       Nickel based
·       Sodium based
 
1.2        What are the UN numbers of the batteries handled on this platform and classified as dangerous goods?
·       Lithium based
-      UN 3090 LITHIUM METAL BATTERIES
-      UN 3091 LITHIUM METAL BATTERIES CONTAINED IN EQUIPMENT
-      UN 3091 LITHIUM METAL BATTERIES PACKED WITH EQUIPMENT
-      UN 3480 LITHIUM ION BATTERIES
-      UN 3481 LITHIUM ION BATTERIES CONTAINED IN EQUIPMENT
-      UN 3481 LITHIUM ION BATTERIES PACKED WITH EQUIPMENT
-      UN 3536 Lithium batteries installed in cargo transport unit
·       Lead based
-      UN 2794, BATTERIES, WET, FILLED WITH ACID
-      UN 2800, BATTERIES, WET, NON SPILLABLE
·       Nickel based
-      UN 2795, BATTERIES, WET, FILLED WITH ALKALI
-      UN 2800, BATTERIES, WET, NON SPILLABLE
-      UN 3496, BATTERIES, NICKEL-METAL HYDRIDE (only for maritime transport)
·       Sodium based
-      UN 3292, BATTERIES, CONTAINING SODIUM or
-      UN 3292, CELLS, CONTAINING SODIUM


1.3        Are button cells dangerous goods?
Not all electrochemistries can  be produced in the form of button cells, most of them are not classified as dangerous goods, with the exception of lithium metal UN 3090 and lithium ion UN 3480 button cells. Lithium button cells are dangerous goods, but given their low lithium content or their low rated capacity, they have some exemptions, particularly when installed in equipment and / or electronic boards.
The applicable transport conditions are clearly described in the e-books.
 
1.4        How to transport used batteries? 
Specific special provisions and packing instructions have to be followed:
-      For lithium batteries, special provision 377 and packing instruction P909,
-      For lead-acid and NiCd batteries, the packing instruction P801,
-      For sodium batteries, the same conditions apply as for new and waste batteries.
-      The applicable transport conditions are clearly described in the e-books.
 
Q. Why are there different summary sheets for WASTE LITHIUM ION CELLS/BATTERIES and CELLS AND BATTERIES FOR DISPOSAL or  RECYCLING ?
A. The differentiation is necessary as in the e-books we have identified waste batteries according to their known characteristics: 
-     if they are still conform and are identified of a type which has passed all tests of UN Manual of Tests and Criteria, session 38.3, they can be transported like new batteries, according to P903
-    if they are not identified as compliant to a tested type, then they cannot be demonstrated as compliant to section 2.9.4 of the UN model regulation. In this case, they may be transported according to the Special provision 377 and P909
1.5        Can defective and damaged (D&D) batteries be transported?
Defective or damaged batteries, of any type, may cause safety problems during transport. The necessary measures must be taken to avoid any releases of liquids, short circuits, breakages, or overheating.
In addition, specific special provisions and packing instructions must be used for lithium batteries. The diagnosis of these batteries must be performed by competent personnel or by the manufacturer, who will also establish whether the D&D batteries are critical for transport (such as the liability to initiate a thermal runaway).
For non-critical D&D, the requirements of special provision 376 and packing instructions P908 and LP904 must be applied.
For critical D&D batteries, liable to rapidly disassemble, dangerously react, produce a flame or a dangerous evolution of heat or a dangerous emission of toxic, corrosive or flammable gases or vapors under normal conditions of carriage shall be packed and carried in accordance with packing instruction P911 or LP906
The applicable transport conditions are clearly described in the e-books.
1.6        Can prototype batteries be transported?
With the exception of lithium batteries, prototype batteries follow the same transport rules as production batteries.
Prototypes of lithium batteries must in practice follow the indications of special provision 310 and the packing instructions P910 and LP905; each cell or battery shall be individually packed in an inner packaging and placed inside an outer packaging.
Each inner packaging shall be completely surrounded by sufficient non-combustible and electrically non- conductive thermal insulation material to protect against a dangerous evolution of heat.
Outer packagings shall conform to the packing group II performance level.
The applicable transport conditions are clearly described in the e-books.
