Whether or not we regard this as an issue, the FAA considers lithium batteries are capable of overheating. And in extreme cases, entering thermal runaway, catching fire, and even exploding. We explain the passenger FAA guidelines for lithium battery transport here, to help our readers avoid embarrassing situations at terminals. Or indeed, inadvertently contributing to an aircraft fire.
Which Lithium Batteries Fall Under The FAA Guidelines?
The FAA rules apply to lithium-ion, and lithium-metal batteries, whether in a device or packaged separately. The agency is concerned various factors could lead to thermal runaway, and these causes include:
- The battery has manufacturing defects that could cause it to overheat internally.
- If the battery is damaged, overheated, exposed to water, or overcharged.
- Poor preparation and packaging that allows unprotected terminals to short circuit.
When we think about it, we realize the FAA guidelines for lithium battery handling are all under user control. For example, we can purchase quality batteries from a reputable supplier.
We can also take reasonable care with our batteries, whether in a device or on their own. And finally, we can take sensible precautions by insulating the terminals of loose batteries. Small things like this can make a great difference to our, and our fellow-passenger safety.
Things to Know Before Boarding an Aircraft
The FAA guidelines for lithium battery precautions when flying, only apply in areas under its jurisdiction. Nonetheless, it seems wise practice to follow them anywhere we travel. The single most important thing would be to declare a problem with a battery. Once we notify the flight crew of a problem, they should know what to do.
In a nutshell then, we may only have lithium-ion and lithium-metal batteries with us on a flight as carry-on baggage, where we can keep an eye on them. This advisory (see link below) includes lithium batteries in devices for external battery charging. As well as spare batteries for personal electronics, including cameras, cell phones, laptop computers, tablets, watches, calculators, etc.
