More information on lithium battery packaging requirements
Lithium ion batteries are the power source for ever greater numbers of products, with everything from phones and MP3 players, to batteries for industrial equipment and even electrical cars using them due to their efficiency, cost, and performance.
However, with greater use has come increased reports of safety incidents, due to both the high “densities” of energy they can contain, plus an increased risk of combustion and fires.
To tackle this, a raft of UN and IATA regulations (International Air Transport Association) were introduced, governing what could be shipped, and how (i.e. detailed criteria that the lithium battery packaging must meet).
Zarges 40582 cases / fireproof battery boxes
The Zarges 40582 case – part of the K470 range of aluminium containers – has been designed to satisfy the requirements of this new legislature, absorbing the energy released during a fire.
The interior of the 40582 case is coated with an intumescent material (i.e. one that foams when heated), meaning the cases’ interior swells up to prevent the fire from spreading further.
The other benefit of this is that the temperature of the fireproof battery box exterior does not exceed 100°C, and any smoke is contained within the case as well (preventing alerts being raised).
Zarges 40582 cases have also been tested under the strictest conditions (including UN3480 Class 9 hazardous goods) to ensure all regulatory requirements are met.
Besides this, Zarges lithium battery transportation cases are durable and robust, making the resistant to impact and shock, as well passing the required drop tests for specific types of transit.
This is also in addition to all of the usability benefits inherent in these aluminium cases. This includes easy loading and unloading thanks to the hinged lids, being resealable with the easy to use clasps (which also makes it possible to lock the cases), as well as being easy to transport thanks to their light weight and comfortable handles.
Flame retardant foam and / or Cirrux inserts
However, just as critical to the success of your lithium ion battery packaging / cases, is that of the interior.
As standard, the fireproof battery boxes are supplied with “Cirrux” interior padding, which helps to contain any fires within the specific compartment where it occurs. Similarly to the cases interior coating, the absorbent material filters out solid components from the battery gases. It also allows liquid constituents to condense on the fibres’ surface, preventing any leaked flammable gases from igniting.
This is also an ideal solution if you are transporting lithium batteries by air, road or sea that vary in size and shape (as the Cirrux can be simply wrapped around these differing configurations).
If you are shipping high volumes of the same battery however, an alternative option is to use Plastazote foam inserts and, in particular, fire-retardant grades.
Whilst the principal of containing any fire and ignitable material within a specific compartment of the Zarges 40582 cases interior is the same, there are a number of inherent benefits of this material.
Firstly, the foam can be designed to provide calculated levels of protection from impact, shock and vibration – something which can be critical if transporting damaged or defective batteries.
The foam recessed can also be shaped to exactly match the profile of the batteries to be placed within, further reducing movement (and potential impact) within the case. This also improves usability in terms of packing and retrieval of the batteries.

Common questions on lithium battery packaging
The below covers some of the most commonly asked questions concerning these Zarges battery cases. However, for even more specific questions, please view the detailed lithium battery guide by clicking here.
What products typically include lithium batteries?
Widely used due to their efficiency, cost and low weight, lithium ion batteries are a key part of the drive towards using electric vehicles, as well as in consumer items such as smartphones and power-tools etc. With the automotive industry in particular using increasing numbers of lithium ion batteries due to the demand for hybrid and fully electrical vehicles, their use is also increasing across items such as drills, electrical garden appliances (e.g. strimmers) and various other tools, mainly due to their light weight.
Why do lithium batteries require specialist packaging for transportation?
Shipping damaged Lithium Ion batteries is arguably the hardest challenge manufacturers now face, alongside lithium battery disposal and recycling. Defective or malfunctioning batteries can lead to overheating, or thermal runaways. The worst-case scenario is this resulting in fires, explosions, or gas leaks. Lithium batteries can also go into thermal runaway when coming into contact with external heat sources, such as fire. As such, lithium batteries – and products containing them – are considered hazardous materials or dangerous goods.
What are UN3480 regulations?
UN 3480 comprises the United Nations regulations covering Lithium ion batteries (shipped by themselves). This is closely related to UN 3481, which are the regulations covering Lithium ion batteries contained in equipment or packed separately with a piece of equipment
Will Zarges fireproof battery boxes meet UN regulations?
Any form of lithium battery packaging will require a fairly in-depth design, testing and approval process. However, Zarges cases with customised interiors have passed performance tests related to the package integrity, plus the aluminium Lithium Ion battery cases have UN approval and feature the mandatory UN certification labelling /marks.
Should I use Cirrux or foam inserts my Zarges case?
Both the Cirrux inserts and flame retardant Plastazote can provide a safe solution for shipping lithium ion batteries. Cirrux tends to be used for lower volumes and when the size and shape of the batteries being shipped my vary, whereas Plastazote lends itself to higher volumes of a specific item. Foam inserts also provide additional protection from impact and mishandling too.
What are fully excepted shipments?
Lithium ion (effectively rechargeable) batteries that are rated at 100-watt hours or less, and lithium metal batteries with two (2) grams or below of lithium, are often classed as fully excepted items. Any “fully-excepted” items only need the appropriate lithium battery mark, displaying the UN number(s), plus a telephone number providing a 24/7 emergency-response number.
Do other battery types require specialist packaging?
Although lithium-based batteries have been the focus of recent legislation, there are a number of other battery types that require specialist shipping / packaging. For example, Lead acid batteries – and those termed as “spill able” – are classed as dangerous goods under Class 8 (controlled by UN 2749). Besides this, Nickel based batteries, whilst having no specific transit limitations / regulations, require many of the same precautions as listed for lead acid batteries to prevent electrical shorts which could result in fire.
