F.A.Q (Frequently Asked Questions) :
Storage of Audioroot batteriesTransport of Audioroot Lithium Ion Batteries
We recommend storing our Lithium-Ion batteries with a charge between 40 and 60 %, i.e 2 or 3 bars on the liquid crystal fuel gauge embedded on each of our batteries. The internal micro controler's power consumption is very low but is capable of fully discharging the battery after several months of storage. We therefore recommend a visual check of the battery's charge status at least every month . Recharge the battery to 60% (3 bars) when it's capacity falls below 40 % (1 bar). We also recommend storing our batteries in a cool place to minimize it's natural capacity loss ; you can improve your battery's life by storing it in a fridge around 4 ° C.
TRANSPORT OF AUDIOROOT LITHIUM ION BATTERIES
What is IATA?
The International Air Transport Association (IATA) has existed since 1945, and in association with the International Civil Aviation Organisation (ICAO) and the United Nations (UN) set clearly defined rules regarding the air transportation of specific items including those deemed as hazardous or
dangerous goods. More importantly, the IATA Dangerous Goods Regulations clarifies the laws
surrounding how goods should be classified, marked, packed and labelled when you place in carryon
or checked-in baggage on civil airlines. The laws also apply to goods that are air freighted and
road freighted as cargo.
How does this affect Lithium Ion batteries?
The transportation of Lithium Ion batteries have their own set of set of regulations under IATA. Air travel is essential to many of our customers and
broadcasters, so when global news stories break or major sports events need to be covered, they
can jump on an airplane with the right amount of AUDIOROOT batteries to power their gear for the whole
event.
For those aware of the previous regulation, the maximum lithium content per cell will be replaced by
the watt hour (Wh) rating of the battery. Therefore, the 8g maximum lithium content has been
replaced by a Wh rating of 100Wh, and the 25g maximum lithium content has been replaced by a Wh
rating of 160Wh.
For users who wish to air freight their batteries as cargo, there are rules regarding the weight of each
package, how the package is labelled and what information must accompany the batteries. Without
a battery below 100Wh in capacity and without following these guidelines, preparing batteries for air
freight can be a time consuming and costly procedure as they must be classified as CLASS 9 -
MISCELLANEOUS DANGEROUS GOODS. This can lead to the shipper incurring extra costs for
specialised packing and written documentation in the form of a Dangerous Goods Note, in addition to
the physical freight costs. Happily, with AUDIOROOT batteries this is not a problem.
What is the law regarding the transportation of Lithium Ion
batteries on commercial airlines?
The 50th edition of the IATA Dangerous Goods Regulations released on 1st January 2009 may be
bad news for some battery users, but not those with AUDIOROOT batteries. A summary of the regulations:
Lithium Ion Batteries less than 100Wh
You can safely carry on-board an unlimited amount of spare batteries, provided that you take safety
precautions and cover any exposed terminals with tape or put them in an insulated plastic bag.
Lithium Ion Batteries over 100Wh but less than 160Wh
You can safely carry on-board a maximum of 2 spare batteries, provided that you take safety precautions
and cover any exposed terminals with tape or put them in an insulated plastic bag. You can
carry on-board 1 extra battery if it is physically installed or attached to your camera or equipment.
Lithium Ion Batteries over 160Wh
You are not allowed to carry-on any spare batteries over 160Wh under any circumstances.
Lithium Ion Batteries as Checked-In Baggage
You cannot check-in as baggage any spare batteries regardless of the battery Wh rating.
However, if your battery is less than 160Wh and is physically installed or attached to your camera or
equipment you can transport this as checked-in baggage.
If your battery is over 160Wh you cannot check-in or carry-on under any circumstances, even if it is
attached or installed to your camera or equipment. To transport batteries over 160Wh, you have to
do so by shipping as separate cargo and classified as CLASS 9 - MISCELLANEOUS DANGEROUS
GOODS.
What AUDIOROOT batteries can I carry-on ?
AUDIOROOT batteries are not affected by the IATA regulations and are all rated below 100Wh, which means
you can carry-on an unlimited amount of spare batteries provided you follow the correct safety
precautions. Please find below a list of AUDIOROOT Lithium Batteries and their Wh rating:
Product Wh Rating:
eSMART Li-95Wh : 95Wh
eSMART Li-75Wh : 75Wh
eSMART Li-37Wh : 37Wh
