TSA rules being effective on January 2008 regarding Li-ION batteries:
Power limit rules (these apply for more powerful batteries, whether spare or
installed, in either carry-on or checked baggage):
For a lithium metal battery, the limit on lithium content is 2 grams per battery.
Almost all lithium metal batteries are non-rechargeable batteries which are disposed of once the initial charge is gone.
Up to 8 grams equivalent lithium content (ELC) for any number of lithium ion batteries
(about 100 watt-hours).
Lithium ion batteries are rechargeable batteries, such as those found in laptop
computers and cell phones.
Up to 2 other lithium ion batteries with an aggregate equivalent lithium content of up to 25
grams, (about 300 watt-hours), in addition to any batteries that fall below the 8-gram
According to this rules Barbolight SL company certifies that:
1. Each Li-ION rechargeable cell 18650 type (18 mm diameter, 65 mm length), 3,7 V 2200
mA ( 8,14 Watt ) has a ELC (Equivalent Lithium Content) of 0,67 gr.
2. Each CR123 primary battery (17 mm diameter, 34,5 mm length) 3 V 1550 mA (4,65 Watt)
has a ELC of 0,38 gr.
3. When locked on “safe-lock mode” it is impossible to activate accidentally any of our lights.
Activation is purely mechanical and they are not sensitive to EM (Electromagnetic fields).
They can be safely shipped on checked-on baggage with batteries inside.
