Batteries such as AA or 9 volt batteries are not regarded as dangerous for sea or air transport, however if these batteries are accidentally crushed they become a transport hazard. All cargo containing batteries must be clearly marked to indicate the contents.
When transporting large batteries it is important that they are identified as to their type including a proper UN number as identified on the SDS. Batteries commonly transported are listed below, along with some procedures that should be followed to ensure safe transport. All batteries are required to be packed in a way that ensures that the terminals cannot be crossed and thus cause a fire risk.
Procedures for transporting batteries
UN 2794: Batteries, wet, filled with acid
These batteries should be packed into a strong outer box and the upright position clearly marked on the outside of the box. For air transport the outer needs to be of a UN approved type and the battery cannot weigh more than 30 kg for shipment on a passenger flight. Batteries in equipment must be securely installed and fastened in the upright position, if the equipment is not to be transported upright then the battery must be removed and packaged as above.
UN 2795: Batteries, wet, filled with alkali
Batteries shall be protected against short circuits. Batteries stacked shall be adequately secured in tiers separated by a layer of non-conductive material. Battery terminals shall not support the mass of other superimposed elements. Batteries shall be packaged or secured to prevent inadvertent movement. For UN 2794 and UN 2795, batteries shall be capable of passing a tilt test at an angle of 45° with no spillage of liquid. 6 Batteries should be transported in rigid outer containers.
UN 2800: Batteries, wet, non-spillable
These batteries must be packaged into a strong outer box. Batteries in equipment must be securely fastened inside of the equipment.
UN 3171: Battery-powered equipment
These batteries must be secure inside of the equipment and if the battery is wet then the upright position should be clearly marked.
UN 3090: Lithium metal batteries*
This relates to individual batteries not packed with or contained in equipment. Ensure battery connections are protected from inadvertent short circuit.
UN 3091: Lithium metal batteries*
Contained in equipment or packed with equipment (eg laptops/cameras, etc.)
UN 3480: Lithium ion batteries*
This relates to individual batteries not packed with or contained in equipment. Ensure battery connections are protected from inadvertent short circuit. This includes Lithium Ion Polymer (Li-Po).
UN 3481: Lithium ion batteries*
Contained in equipment or packed with equipment (eg laptops/cameras, etc.). This includes Lithium Ion Polymer (Li-Po).
*Contact Supply Services for information regarding the transport of lithium batteries to Antarctica and sub-Antarctica.
For Air Transport: Lithium batteries can not travel as checked baggage and must only travel as carry on baggage. This includes lithium batteries installed in devices as well as loose batteries.
