Following is advice from the U.S. Department of Transportation's Pipeline and Hazardous Materials Safety Administration's SafeTravel.dot.gov web site on flying with battery-powered devices:
- Batteries pose little risk contained in the devices they power. Taking the battery out of the device does not enhance safety. To be safest, carry the device with you, not in your checked baggage. Do not remove the battery!
- Carry your battery-powered devices or spare batteries in your carry-on baggage. In the passenger compartment, flight crews can better monitor safety conditions to prevent an incident, and can access fire extinguishers, if an incident does happen.
- Finally, if you must carry a battery-powered device in your checked baggage, package it to prevent inadvertent activation. Cordless power tools, for instance, should be packed in a protective case, with a trigger lock engaged.
Many travelers like the convenience of readily available spare batteries. It's safe to travel with spare batteries, as long as you follow these simple spare battery tips:
- Pack spare batteries in carry-on baggage. In the passenger compartment, flight crews can better monitor safety conditions to prevent an incident, and can access fire extinguishers, if an incident does happen.
- Keep spare batteries in the original retail packaging, to prevent unintentional activation or short-circuiting.
- For loose batteries, place tape across the battery's contacts to isolate terminals. Isolating terminals prevents short-circuiting.
- If original packaging is not available, effectively insulate battery terminals by isolating spare batteries from contact with other batteries and metal. Place each battery in its own protective case, plastic bag, or package. Do not permit a loose battery to come in contact with metal objects, such as coins, keys, or jewelry.
- Use only chargers designed for your type of batteries. If unsure about compatibility, contact the product manufacturer.
- Take steps to prevent crushing, puncturing, or putting a high degree of pressure on the battery, as this can cause an internal short-circuit, resulting in overheating.
