TSA Regulations Concerning Lithium Batteries


Effective January 1, 2008, you may not pack spare lithium batteries in your checked baggage.

You may pack spare lithium batteries in your carry-on baggage. Please see the TSA's Spare Battery Tips and How-To sections to find out how to pack spare batteries safely. If you pack a device containing batteries, secure it against activation by locking the activation switch in the "off" position, placing the device in a protective case, or by other appropriate measures.

While there is no explosion hazard associated with lithium batteries, the Federal Aviation Administration has studied fire hazards associated with both primary and lithium-ion cells, and their extensive research is publicly available. As a result of this research, the FAA no longer allows large, palletized shipments of these batteries to be transported as cargo on passenger aircraft.

The research also shows that an explosion will not result from shorting or damaging either lithium-ion or primary lithium batteries. Both are, however, extremely flammable. Primary lithium batteries cannot be extinguished with firefighting agents normally carried on aircraft, whereas lithium-ion batteries are easily extinguished by most common extinguishing agents, including those carried on board commercial aircraft.

The TSA has and will continue to work closely with the FAA on potential aviation safety and security issues, and TSA security officers are thoroughly and continually trained to find explosive threats. TSA does not have plans to change security regulations for electronic devices powered by lithium batteries.

The information we are providing may be changed by the TSA at any time without notice. So in order to have the latest information and updates on this restriction, please visit the TSA website.
