Transport of Lithium Metal and Lithium Ion Batteries

Revised for the 2015 Regulations

Introduction

This document is based on the provisions set out in the 2015-2016 Edition of the ICAO Technical Instruction for the Safe Transport of Dangerous Goods by Air and the 56th Edition of the IATA Dangerous Goods Regulations (DGR).

The purpose of this document is to provide guidance for complying with provisions applicable to the transport by air of lithium batteries as set out in the DGR.

Specifically the document provides information on:

Definitions; Classification (including classification flowcharts); Transport Conditions Exceptions; Special Provisions; Prohibitions; Passenger Provisions; and Frequently Asked Questions

Definitions

Lithium Battery – The term “lithium battery” refers to a family of batteries with

different chemistries, comprising many types of cathodes and electrolytes. For the purposes of the DGR they are separated into:

Lithium metal batteries. Are generally primary (non-rechargeable) batteries that

have lithium metal or lithium compounds as an anode. Lithium metal batteries are generally used to power devices such as watches, calculators, cameras, temperature data loggers.

Note:

As of 1 January 2015 lithium metal batteries packed by themselves (not contained in or packed with equipment) are forbidden for transport as cargo on passenger

aircraft).

Figure 1 - Example of Lithium Metal Batteries

Lithium-ion batteries (sometimes abbreviated Li-ion batteries) are a type of

secondary (rechargeable) battery commonly used in consumer electronics. Also included within the category of lithium-ion batteries are lithium polymer batteries.

Lithium-ion batteries are generally found in mobile telephones, laptop computers, etc.

Figure 2 - Example of a Lithium Ion Battery

The technical definition of a battery and cell, as indicated in the UN Manual of Tests

and Criteria, is as follows:

“Battery” means two or more cells which are electrically connected together and fitted with devices necessary for use, for example, case, terminals, marking and protective devices. A single cell lithium battery is considered a "cell" and must be tested according to the testing requirements for "cells" for the purposes of these Regulations and the provisions of subsection 38.3 of the UN Manual of Tests and Criteria (see also the definition for "cell").

Note:

Units that are commonly referred to as “battery packs”, “modules” or “battery

assemblies” having the primary function of providing a source of power to another piece of equipment are for the purposes of these Regulations and the provisions of Subsection 38.3 of the UN Manual of Tests and Criteria treated as batteries.

“Cell” means a single encased electrochemical unit (one positive and one negative electrode) which exhibits a voltage differential across its two terminals. Under these Regulations and the UN Manual of Tests and Criteria, to the extent the encased electrochemical unit meets the definition of “cell” herein, it is a “cell”, not a “battery”, regardless of whether the unit is termed a “battery” or a “single cell battery” outside of these Regulations and the UN Manual of Tests and Criteria

Button cell or battery means a round small cell or battery when the overall height is less than the diameter.

Classification (DGR 3.9.2.6)

Lithium batteries are classified in Class 9 – Miscellaneous dangerous goods as:

UN 3090, Lithium metal batteries; and

UN 3480, Lithium ion batteries

or, if inside a piece of equipment or packed separately with a piece of equipment as:

UN 3091, Lithium metal batteries contained in equipment; or

UN 3091, Lithium metal batteries packed with equipment; and

UN 3481, Lithium ion batteries contained in equipment; or

UN 3481, Lithium ion batteries packed with equipment.

In the absence of exceptions, these batteries must be shipped in quantities that comply with the limitations contained in the DGR (see DGR Table 4.2 and the applicable packing instruction). They must be contained in a UN specification packaging as prescribed by the applicable packing instruction in the DGR. A

completed package must display a Class 9 hazard label in addition to markings that identify the applicable proper shipping name and UN number. A shipper must document the shipment using a Shipper’s Declaration for Dangerous Goods.

Beginning 1 Jan 2013 the classification criteria for lithium batteries stipulates that cells and batteries must be manufactured under a quality management program. () includes the elements that must be included in such a program.

Transport Conditions

The following information is a summary of the conditions that apply to various sizes of batteries for air transport. More details on the exceptions are found in the next section of this document.

1. Section I / IA Packing Instructions 965 – 970

Lithium ion and lithium metal cells and batteries (PI 965 & PI 968, Section IA and PI 966, PI 967, PI 969 & PI 970, Section I) are subject to all of the applicable

Packages containing lithium batteries, or lithium batteries contained in, or packed with, equipment that meet the provisions of Section II of these packing instructions are not required to have a Class 9 hazard label and there is no requirement for a Shipper’s Declaration for Dangerous Goods for consignments of these batteries. However, in the event of an incident involving these batteries, the incident reporting requirements apply.

Note:

Only batteries that have successfully passed the test procedures of Part III, Sub-

Section 38.3 of the UN Manual of Tests and Criteria qualify under this exception. This is also true for so-called “OEM” or “aftermarket” batteries. Any battery manufacturer or distributor should be able to provide documentation confirming that the batteries have been so tested.

Quantities of lithium metal and lithium ion cells and batteries that exceed the “per package” limits described in Section II of the packing instruction 965 (Table 965-II) and 968 (Table 968-II) must be assigned to class 9 and shipped as “Section IB”. All applicable requirements contained in the IATA Dangerous Goods Regulations

relating to these commodities must be complied with, including the training

requirements, except that UN Specification packaging is not required.

Packages must bear the Class 9 hazard label in addition to the lithium battery

handling label.

Lithium metal and lithium ion batteries larger than those permitted by Section II of the applicable packing instruction must be assigned to Class 9 and consigned as

UN 3090 (Lithium metal batteries), UN 3480 (Lithium ion batteries), UN 3091 (Lithium metal batteries contained in equipment or Lithium metal batteries packed with

equipment) or UN 3481 (Lithium ion batteries contained in equipment or Lithium ion batteries packed with equipment). All applicable requirements contained in the IATA Dangerous Goods Regulations relating to these commodities must be complied with, including the training requirements; a “Shipper’s Declaration for Dangerous Goods” must be issued, and packages must bear the Class 9 hazard label.

Special Provisions

There are a number of special provisions which may allow for the transport of lithium batteries other than in accordance with the defined conditions or limits, or which require the shipper to take additional precautions when preparing batteries for

transport. The special provisions applicable to lithium batteries are set out following. Notwithstanding the general requirement that prior to being transported each type of lithium battery must have successfully passed the UN test requirements, there is provision for prototype lithium batteries that have not yet passed the UN test

requirements to be shipped for testing purposes, this testing includes pre-production or product compatibility testing, in accordance with Special Provision A88, as follows:

A88 Prototype or low production, (i.e. annual production runs consisting of no

more than 100 lithium cells or batteries) lithium cells or batteries that have not

been tested to the requirements in subsection 38.3 of the UN Manual of Tests

and Criteria may be transported aboard cargo aircraft, if approved by the

appropriate authority of the State of origin and the following requirements are

met:

a) except as provided in paragraph (c), the cells or batteries must be

transported in an outer packaging that is a metal, plastic or plywood drum

or a metal, plastic or wooden box and that meets the criteria for Packing

Group I packagings;

b) except as provided in paragraph (c), each cell or battery must be

individually packed in an inner packaging inside an outer packaging and

surrounded by cushioning material that is non-combustible, and non-

conductive. Cells or batteries must be protected against short-circuiting;

c) lithium batteries with a mass of 12 kg or greater and having a strong,

impact resistant outer casing, or assemblies of such batteries, may be

packed in strong outer packagings or protective enclosures not subject to

the requirements of Section 6 of these Regulations. The batteries or

battery assemblies must be protected against short circuiting; and

d) a copy of the document of approval showing the quantity limitations must

accompany the consignment.

Irrespective of the limit specified in Column L of Table 4.2, the battery or

battery assembly as prepared for transport may have a mass exceeding 35

kg.

For air transport, specific quantity limits apply to the net weight of lithium batteries in a package. The maximum net weight of lithium batteries per package for Cargo Aircraft Only is 35 kg. However, there is provision for large lithium batteries that have a net weight exceeding 35 kg to be consigned on a cargo aircraft in accordance with Special Provision A99 as follows:

A99 Irrespective of the per package quantity limit for cargo aircraft specified in Column L of the List of Dangerous Goods (Subsection 4.2), and in Section I of Packing Instructions 965, 966, 967, 968, 969 or 970, a lithium battery or battery assembly (UN 3090 or UN 3480), including when packed with, or contained in equipment (UN 3091 or UN 3481) that meets the other requirements of Section I of the applicable packing instruction may have a mass exceeding 35 kg, if approved by the appropriate authority of the State of origin. A copy of the document of approval must accompany the consignment. There will be occasion where a manufacturer may wish to have a defective battery returned for analysis. However, where such batteries may pose a safety risk they are prohibited from transport by air as set in Special Provision A154, as follows:

A154 Lithium batteries identified by the manufacturer as being defective for

safety reasons, or that have been damaged, that have the potential of producing a dangerous evolution of heat, fire or short circuit are forbidden for

transport (e.g. those being returned to the manufacturer for safety reasons).

One of the major risks associated with the transport of batteries and battery-powered equipment is short-circuit of the battery as a result of the battery terminals coming into contact with other batteries or metal objects. Special Provision A164 requires that all batteries and battery-powered equipment must be packed to prevent short circuit an inadvertent operation as follows:

A164 Any electrical battery or battery-powered device, equipment of vehicle

having the potential of a dangerous evolution of heat must be prepared for

transport so as to prevent:

(a) a short circuit (e.g. in the case of batteries by the effective insulation of

exposed terminals; or in the case of equipment, by disconnection of the

battery and protection of exposed terminals); and

(b) unintentional activation.

When a shipment of a combination of lithium batteries contained in equipment and lithium batteries packed with equipment is presented for transport, the classification is to be lithium batteries packed with equipment as indicated by special provision A181.

A181 When a package contains a combination of lithium batteries contained

in equipment and lithium batteries packed with equipment, the package must

be marked UN 3091 Lithium metal batteries packed with equipment, or UN

3481 Lithium ion batteries packed with equipment as appropriate. If a

package contains both lithium ion batteries and lithium metal batteries, the

package must be marked as required for both battery types. However, button

cell batteries installed in equipment (including circuit boards) need not be

considered.

Questions have been asked regarding whether to classify equipment with lithium batteries as battery-powered equipment, or only lithium batteries contained in

equipment. Special Provision A182 makes it clear that the requirement is to use the lithium battery specific entries when only those batteries are present.

A182 Equipment containing only lithium batteries must be classified as either

UN 3091 or UN 3481.

It has been clarified that waste batteries are not permitted in air transport with the addition of Special Provision A183.

A183 Waste batteries and batteries being shipped for recycling or disposal are prohibited from air transport unless approved by the appropriate national

authority of the State of Origin and the State of the Operator.

Questions have been asked regarding whether to classify vehicles powered only by lithium batteries as vehicles, or using a lithium battery entry. Special Provision A185 makes it clear that the requirement is to use the battery-powered vehicle entry.

A185 Vehicles only powered by lithium metal batteries or lithium ion batteries

must be consigned under the entry UN 3171, Battery-powered vehicle

Effective 1 January 2015 lithium metal batteries by themselves (UN 3090) are

prohibited on passenger aircraft. An exemption may be granted by the States

concerned in accordance with Special Provision A201:

A201 States concerned may grant an exemption from the prohibition to transport lithium metal batteries as cargo on passenger aircraft in accordance with 1.2.6.

Authorities issuing exemptions in accordance with this special provision must provide a copy to the Chief of the Cargo Safety Section within three months of issuance via email at: CSS@icao.int, via facsimile at +1 514-954-6077 or via post to the following address:

Prohibitions

Transport of lithium metal batteries

Lithium metal batteries shipped by themselves (UN 3090) are not permitted on passenger aircraft. All packages prepared in accordance with packing instruction 968, Section IA, IB and II, must bear a Cargo Aircraft Only label, in addition to existing labels.

Transport to, from or through the United States

Lithium metal batteries shipped to, from or through the United States are subject to additional limitations specified in the US national dangerous goods regulations contained in Code of Federal Regulations Title 49 (49 CFR). The basis of these limitations is reflected in State Variation USG-02, which states that:

Primary (non-rechargeable) lithium metal batteries and cells, (UN 3090), are forbidden for transportation aboard passenger-carrying aircraft. Such batteries

transported in accordance with Section I of Packing Instruction 968 must be labelled with the CARGO AIRCRAFT ONLY label. Such batteries transported in accordance with Section II of Packing Instruction 968 must be marked “PRIMARY LITHIUM BATTERIES — FORBIDDEN FOR TRANSPORT ABOARD PASSENGER

AIRCRAFT” or “LITHIUM METAL BATTERIES — FORBIDDEN FOR TRANSPORT ABOARD PASSENGER AIRCRAFT”.

Primary (non-rechargeable) lithium metal batteries and cells contained in or packed with equipment (UN 3091) are forbidden for transportation aboard passenger-carrying aircraft unless:

1. the equipment and the batteries and cells are transported in accordance with

Packing Instruction 969 or 970, as appropriate;

2. the package contains no more than the number of lithium metal batteries or

cells necessary to power the intended piece of equipment;

3. the lithium content of each cell, when fully charged, is not more than 5 grams;

4. the aggregate lithium content of the anode of each battery, when fully

charged, is not more than 25 grams; and

5. the net weight of lithium batteries does not exceed 5 kg (11 lb).

Primary (non-rechargeable) lithium metal batteries and cells contained in or packed with equipment (UN 3091) and transported in accordance with Section I of Packing Instruction 969 or 970 that do not conform to the above provisions are forbidden for transportation aboard passenger-carrying aircraft and must be labelled with the CARGO AIRCRAFT ONLY label.

Primary (non-rechargeable) lithium metal batteries and cells contained in or packed with equipment (UN 3091) and transported in accordance with Section II of Packing Instruction 969 or 970 that do not conform to the above provisions are forbidden for transportation aboard passenger-carrying aircraft and must be marked “PRIMARY LITHIUM BATTERIES — FORBIDDEN FOR TRANSPORT ABOARD PASSENGER AIRCRAFT” or “LITHIUM METAL BATTERIES — FORBIDDEN FOR TRANSPORT

ABOARD PASSENGER AIRCRAFT”.

Passenger Provisions

Transport within Passenger Baggage

Certain restrictions apply to the carriage of lithium metal and lithium ion batteries even when carried by passengers as baggage. Once again, only batteries that have successfully passed the Tests outlined in Part III, Sub-Section 38.3 of the UN Manual of tests and criteria may be carried.

As said before batteries manufactured, distributed or sold by major companies do meet this requirement, however, certain replacement batteries which are not OEM or aftermarket batteries but simply low-cost copies of those – also called “fakes” – may not have undergone the required tests. Untested batteries are consequently excluded from air transport.

Users of equipment powered by lithium metal and lithium ion batteries should

therefore be vigilant when buying replacement batteries from unknown sources, such as on markets or Internet auction platforms. The differences between genuine and copied battery types may not be visible but could be very dangerous; such untested batteries may have a risk of overheating or causing fires.

Because of the risks associated with the carriage of spare batteries these may not be transported within passenger checked baggage. Spare batteries must be in carry-on baggage.

These requirements are stipulated by subparagraph 2.3.4.7 and 2.3.5.9 of the IATA Dangerous Goods Regulations:

2.3.4.7 Lithium Battery-Powered Electronic Devices

Lithium battery-powered electronic devices are permitted in checked and carry-on baggage with the approval of the operator as follows:

(a) portable medical electronic devices (Automated External Defibrillators (AED),

Nebulizer, Continuous Positive Airway Pressure (CPAP), etc.) containing lithium metal or lithium ion cells or batteries may be carried by passengers for medical use as follows:

1. for lithium metal or lithium alloy batteries, a lithium content exceeding 2 g, but

not exceeding 8 g; or

2. for lithium ion batteries, a watt-hour rating exceeding 100 Wh, but not

exceeding 160 Wh;

3. batteries must be of a type that meets the requirements of the UN Manual of

Tests and Criteria, Part III, subsection 38.3.

(b) portable electronic devices (such as cameras, lap-top computers, camcorders)

containing lithium ion batteries as follows:

1. lithium ion batteries with a watt-hour rating exceeding 100 Wh, but not

exceeding 160 Wh;

Tests and Criteria, Part III, subsection 38.3.

2.3.5.9 Portable Electronic Devices (including medical devices) containing Batteries

2.3.5.9.1 Portable electronic devices (including medical devices) (such as watches, calculating machines, cameras, cellular phones, lap-top computers, camcorders, etc.) containing batteries when carried by passengers or crew for personal use, which should be carried in carry-on baggage. Spare batteries must be individually protected to prevent short circuits by placement in the original retail packaging or by otherwise insulating terminals, e.g. by taping over exposed terminals or placing each battery in a separate plastic bag or protective pouch, and carried in carry-on baggage only. In addition, lithium batteries are subject to the following conditions:

(a) each installed or spare battery must not exceed:

1. for lithium metal or lithium alloy batteries, a lithium content of not more than

2 g; or

2. for lithium ion batteries, a watt-hour rating of not more than 100 Wh.

(b) batteries and cells must be of a type that meets the requirements of the UN

Manual of Tests and Criteria, Part III, subsection 38.3;

(c) articles containing lithium metal or lithium ion cells or batteries, the primary

purpose of which is to provide power to another device, are permitted in carry-on baggage only. These articles must be individually protected to prevent short

circuits by placement in the original retail packaging or by otherwise insulating terminals, e.g. by taping over exposed terminals or placing each battery in a separate plastic bag or protective pouch.

(d) if devices are carried in checked baggage the passenger/crew member must take

measures to prevent unintentional activation.

There is also provision, with the approval of the airline, for larger lithium ion batteries with a watt-hour rating in excess of 100 Wh, but not more than 160 Wh in equipment and no more than two spare lithium ion batteries as set out in subparagraph 2.3.3.2 as follows:

2.3.3.2 Spare Lithium Batteries

Spare lithium batteries are permitted in carry-on baggage as follows:

(a) for portable medical electronic devices (Automated External Defibrillators (AED),

Nebulizer, Continuous Positive Airway Pressure (CPAP), etc.):

1. no more than 2 lithium ion batteries with a watt-hour rating exceeding 100 Wh

but not exceeding 160 Wh or lithium metal batteries, with a lithium content

exceeding 2 g but not exceeding 8 g may be carried;

2. spare batteries must be individually protected so as to prevent short circuits

(by placement in original retail packaging or by otherwise insulating terminals, e.g. by taping over exposed terminals or placing each battery in a separate

plastic bag or protective pouch);

Tests and Criteria, Part III, subsection 38.3. No more than two individually

protected spare batteries per person may be carried.

(b) for portable electronic devices (such as cameras, lap-top computers,

camcorders):

1. no more than 2 lithium ion batteries exceeding a watt-hour rating of 100 Wh

but not exceeding 160 Wh may be carried;

2. spare batteries must be individually protected so as to prevent short circuits

(by placement in original retail packaging or by otherwise insulating terminals,

e.g. by taping over exposed terminals or placing each battery in a separate

plastic bag or protective pouch);

3. batteries must be of a type that meet the requirements of the UN Manual of

Tests and Criteria, Part III, subsection 38.3. No more than two individually

protected spare batteries per person may be carried.

Lithium ion batteries exceeding a watt-hour rating of 100 Wh but not exceeding 160 Wh may be carried as spare batteries in carry-on baggage, or in equipment in either checked or carry-on baggage. Batteries must be of a type that meets the requirements of the UN Manual of Tests and Criteria, Part III, subsection 38.3. No more than two individually protected spare batteries per person may be carried. Although the text provided above does not impose a limit on the number of lithium metal and lithium ion batteries that fall under the 2 g or 100 Wh limitation (See

2.3.5.9) being carried as spares within a passenger’s carry-on baggage it must be emphasized that the number of spares must be “reasonable” in the context of the equipment used by the passenger and his or her itinerary. Furthermore, these must be intended to power portable electronic devices (including, but not limited to,

cameras and professional film equipment, laptop computers, MP3 players, cell

phones, Personal Digital Assistants (PDA’s), pocket calculators etc).

Batteries which are carried for the purpose of resale or beyond personal needs are clearly not covered.

The regulations imposed on these commodities by the United States competent authorities (Department of Transportation and FAA) match the ICAO / IATA

regulations addressed in this document.

Lithium-ion battery powered wheelchairs or other similar mobility aids for use by

passengers whose mobility is restricted by either a disability, their health or age, or a temporary mobility problem (e.g. broken leg), are permitted in air transport but

subject to the following conditions:

(a) the batteries must be of a type which meets the requirements of each test in the

UN Manual of Tests and Criteria, Part III, subsection 38.3;

(b) the operator must verify that:

(1) battery terminals are protected from short circuits, e.g. by being enclosed

within a battery container,

(2) the battery must be securely attached to the wheelchair or mobility aid; and

(3) electrical circuits have been inhibited.

(c) the mobility aids must be carried in a manner such that they are protected from

being damaged by the movement of baggage, mail, or other cargo;

(d) where a battery powered or other similar mobility aid is specifically designed to

allow its battery(ies) to be removed by the user (e.g. collapsible)

(1) the battery(ies) must be removed. The wheelchair / mobility aid may then be

carried as checked baggage without restriction;

(2) the battery(ies) must be protected from short circuit by insulating the terminals

(e.g. by taping over exposed terminals);

(3) the removed battery(ies) must be protected from damage (e.g.) by placing

each battery in a protective pouch. The battery(ies) must be carried in the

passenger cabin;

(4) removal of the battery from the device must be performed by following the

instructions of the manufacturer or device owner;

(5) the battery must not exceed 300 Wh;;

(6) a maximum of one spare battery not exceeding 300 Wh or two spares each

not exceeding 160 Wh may be carried; and

(e) the pilot-in-command must be informed of the location of the mobility aid with an

installed battery or the location of the lithium battery when removed and carried in the cabin.

(f) It is recommended that passengers make advance arrangements with each

operator.

Note: most scooters have a key which can be switched to the off position, removed and given to the passenger for safe keeping. However, most power chairs are

switched on and off with a push-button which could be reactivated in flight by the

inadvertent movement of baggage or cargo. Accordingly, further steps are required to inhibit the circuits of such devices, for example separating the power supply between the batteries and the control mechanism by disconnecting cable plugs or connectors, or inserting an inhibiting plug. Any exposed electrical terminals must be insulated to prevent short circuit. Batteries should not be routinely disconnected or removed,

since this is often very difficult to do, and if not done properly can increase the risk of a fire.

To check that electrical circuits have been inhibited, prior to loading place the device into drive mode (i.e. not freewheel mode), try to power up the device be pressing the on/off switch and see if use of the joystick results in the mobility aid moving. A check should also be made that batteries are securely attached to the mobility aid and battery terminals are protected from short circuit. If it is evident that an electric mobility aid has not been made safe, it must not be loaded.

Once loaded onboard the aircraft or into a ULD, the electric mobility aid should be returned to drive mode as this will help prevent it moving with the potential for

damage. Devices must be secured to prevent movement and may require load-spreading (consult the airline ground handling manual for details).

Frequently Asked Questions

Part 1 – Questions Related to Definitions

A. What are the various types of lithium batteries?

Lithium batteries fall into two broad classifications; lithium metal batteries and lithium ion batteries. Lithium metal batteries are generally non-rechargeable and contain metallic lithium. Lithium ion batteries do not contain metallic lithium and are

rechargeable.

B. What are lithium polymer batteries?

A lithium polymer battery is a type of lithium ion battery. Generally, the main

difference is lithium ion polymer batteries contain a polymer electrolyte.

C. What is the difference between a lithium cell and a lithium battery?

A lithium cell is a single encased electrochemical unit consisting of one positive and one negative electrode that exhibits a voltage differential across the two terminals. A lithium battery is two or more cells electrically connected. A single cell battery is considered a cell and not a battery for the purposes of the limitations set out in the DGR. primary function of providing a source of power to another piece of equipment

are for the purposes of these Regulations treated as batteries. Refer to the

section on Definitions for complete details.

D. How are component cells connected to form a battery?

Cells in batteries may be connected in parallel, in series, or in a combination of the two. When cells are connected in series the voltage of the battery increases but the capacity in ampere-hours (Ah) does not change. By contrast, when cells are

connected in parallel the capacity in ampere-hours of the battery (Ah) increases but the voltage stays the same.

E. How do I determine the watt-hour rating for a particular lithium ion battery? The watt-hour (Wh) rating is a measure by which lithium ion batteries are regulated. Section II Lithium ion batteries manufactured after 1 January 2009 are required to be marked with the watt-hour rating. Section I Lithium ion batteries manufactured after 31 December 2011 are required to be marked with the watt-hour rating.

You can also arrive at the number of watt-hours your battery provides if you know the battery’s nominal voltage (V) and capacity in ampere-hours (Ah):

Ah x V = Wh

This information is often marked on the battery.

Note that if only the milli-ampere-hours (mAh) are marked on the battery then divide that number by 1000 to get ampere-hours (Ah) (i.e. 4400 mAh / 1000 = 4.4. Ah).

Most lithium ion batteries marketed to consumers are below 100 watt-hours. If you are unsure of the watt-hour rating of your lithium ion battery, contact the

manufacturer.

F. What is a button cell battery?

A button cell battery is a round small cell or battery where the overall height is less than the diameter.

Part 2 – Questions related to Packaging and Transport Provisions

A. How do I safely package lithium batteries for transport?

One of the major risks associated with the transport of batteries and battery-powered equipment is short-circuit of the battery as a result of the battery terminals coming into contact with other batteries, metal objects, or conductive surfaces. Packaged

batteries or cells must be separated in a way to prevent short circuits and damage to terminals. They must be packed in a strong outer packaging or be contained in equipment. Sample packaging meeting these requirements is shown below:

B. How can batteries be effectively protected against short circuit?

Methods to protect against short circuit include, but are not limited to, the following methods:

a. Packing each battery or each battery-powered device when

practicable, in fully enclosed inner packagings made of non-

conductive material (such as a plastic bag);

b. Separating or packing batteries in a manner to prevent contact with

other batteries, devices or conductive materials (e.g., metal) in the

packagings; and

c. Ensuring exposed terminals or connectors are protected with non-

conductive caps, non-conductive tape, or by other appropriate means.

If not impact resistant, the outer packaging should not be used as the sole means of protecting the battery terminals from damage or short-circuiting. Batteries should be securely cushioned and packed to prevent shifting which could loosen terminal caps or reorient the terminals to produce short circuits.

Terminal protection methods include but are not limited to the following:

a. Securely attaching covers of sufficient strength to protect the terminals; b. Packaging the battery in a rigid plastic packaging; and c. Constructing the battery with terminals that are recessed or otherwise protected so that the terminals will not be subjected to damage if the package is dropped.

C. What does the lithium battery handling label look like and when is it

required?

The lithium battery handling label is required as specified in the additional

requirements of Section II of packing instructions 965, 966, 967, 968, 969 and 970. It is also required as specified in the additional requirements of Section IB of packing instruction 965 and 968 in addition to the Class 9 label and Cargo Aircraft Only label for Packing Instruction 968. The label is as shown in Figure 7.4.H of the IATA Dangerous Goods Regulations. The border of the label must have red diagonal hatchings with text and symbols in black on a contrasting background. The lithium battery handling label may be printed directly on the outer packaging provided that there is sufficient contrast between the elements of the lithium battery label and the colour of the packaging material. The minimum dimensions are 120 mm wide x

110 mm high.

* Place for “Lithium ion battery” and/or “Lithium metal battery”
