You may have noticed that airlines strictly prohibit the transport of lithium batteries in checked luggage or as cargo. This has left many wondering, “Why no lithium batteries on planes?”
In this article, we will take a closer look at the reasons behind the ban on lithium batteries in air travel and explore the safety concerns that have led to these regulations.
Why No Lithium Batteries On Planes? Getting To Understand The Reasons
You might wonder why lithium batteries aren’t allowed on airplanes. The reason is simple: safety. These batteries can be a fire hazard, especially when they get damaged or short-circuited.
The heat they generate can potentially start a fire, and that’s a risk airlines want to avoid.
To keep everyone safe, airlines have strict rules in place. They don’t allow you to check these batteries in as luggage, but there’s still good news. You can travel with your devices that have lithium batteries by carrying them in your hand luggage.
This way, you can keep a close watch on them and reduce the risk of any damage during your journey.
When packing your lithium batteries, be sure to take some precautions. Store each battery in its original packaging, and if there are any loose terminals, cover them with electrical tape or some other insulation material.
For added safety, it’s also a good idea to power off all devices with lithium batteries during the flight and store them away from metal objects.
By following these guidelines, you can travel with your devices and lithium batteries more safely and confidently.
What Type Of Battery Is Not Allowed On Airplanes?
There are two types of batteries you can’t bring on airplanes: lithium-metal batteries and lithium-ion batteries. Let me explain why.
- Lithium metal batteries are these small and lightweight ones that contain a really flammable substance called lithium metal. When they come into contact with other materials or get damaged, they can catch fire or cause short circuits. This has actually led to fires on planes, so airlines don’t allow them in checked luggage.
- Now, lithium-ion batteries are more common. You’ll find them in everyday things like laptops, smartphones, cameras, power banks, and e-cigarettes. While they do have some volatile stuff in them, they’re not as likely to catch fire as lithium metal batteries.
But there’s still a catch. You can’t put electronic cigarettes and vaping devices in checked baggage because they can explode or start a fire. So, it’s important to know the rules when you’re traveling with these types of batteries.
What Size Lithium Batteries Are Not Allowed On Airplanes?
When it comes to lithium batteries on airplanes, there are some rules to follow. Lithium metal batteries, the non-rechargeable ones, weighing more than two grams per battery are a no-go. Also, lithium-ion batteries, the rechargeable kind, with a rating exceeding 100 watt-hours (Wh) per battery can’t be carried, whether it’s in your carry-on or checked luggage.
Now, these limits pretty much cover the batteries you’d find in most consumer electronics. But there’s a bit more to it. Airlines won’t allow any lithium metal or lithium-ion batteries larger than 160 watt-hours (Wh).
If your device has a non-removable battery, it has to be packed in your carry-on bag, and you need to disconnect the battery from the device. These guidelines help keep everyone safe in the skies.
Will TSA Confiscate Lithium Batteries?
You might be concerned about the TSA confiscating your lithium batteries, but the good news is they generally won’t take them away. They might ask you to take your batteries out of your carry-on bag for a screening, but they can’t confiscate them without approval from an airline representative.
In most cases, airlines permit spare lithium-ion and metal batteries in both your carry-on and checked luggage, but there might be limits on how many you can bring.
It’s not just about the number, though. You also need to ensure your batteries are protected from short circuits. This means that loose batteries must be stored in a case, pouch, or plastic bag and kept separate from metal objects, like keys or coins, in your luggage.
So, if you follow these safety measures, you can travel with your lithium batteries without worrying about the TSA taking them away at the airport.
What Are TSA Restrictions On Lithium Batteries On A Plane?
When traveling, it’s crucial to pack spare lithium batteries in your carry-on luggage. This rule applies to both non-rechargeable and rechargeable lithium batteries, and their capacity should not exceed 100 watt hours (Wh). If you have batteries that exceed this limit, you’ll need to seek special permission from the airline before your flight.
For lithium metal (non-rechargeable) batteries, they are limited to 2 grams of lithium per battery. Any devices containing these batteries should also be placed in your carry-on bag, and remember to power off these devices.
If your device happens to have both lithium-metal and lithium-ion batteries, they must be removed from the device. Store each battery type separately and make sure to follow the specific restrictions for their transport.
How Does TSA Detect Lithium Batteries?
The secret to identifying lithium-ion batteries at airport security lies in the power of X-rays! TSA agents employ a method known as X-ray absorption to spot these batteries and further examine them. When X-rays penetrate your luggage, they create an image on the opposite side.
TSA personnel examine this image to check for any suspicious items. However, unlike metal objects, lithium-ion batteries don’t interact with X-rays in the same way. Instead of bouncing off them, X-rays are absorbed by the battery, forming a distinctive pattern on the X-ray image.
This method allows TSA agents to single out lithium-ion batteries amidst the array of items in your bag.
Furthermore, X-ray absorption helps TSA personnel determine how many batteries are inside your bag and their sizes and shapes, which aids in identifying potentially risky items before they make it onto the plane.
Apart from X-ray absorption, TSA employs other techniques to detect lithium-ion batteries in your luggage.
One such technique is called “density scanning,” which involves using low-level radiation to measure the density of different objects inside a bag.
Another method used is called “thermal imaging,” which involves using infrared cameras to detect heat signatures from the batteries.
What Kinds Of Batteries Does The FAA Allow In Carry-On Baggage?
The FAA provides specific guidelines on the types of batteries that can be brought into the cabin. Here’s a brief summary:
- Dry cell alkaline batteries, such as AA, AAA, C, D, and 9-volt cells, are allowed in carry-on bags.
- The same rule applies to dry cell rechargeable batteries, such as Nickel Metal Hydride (NiMH) and Nickel Cadmium (NiCd).
It’s crucial to safeguard your batteries from damage and short circuits. This means covering any exposed terminals with electrical tape or keeping them in their original packaging when possible.
Additionally, it’s important to ensure that your battery-powered devices are shielded against accidental activation or heat generation.
If a battery is damaged or recalled, whether it’s inside a device or not, it should not be brought on board the aircraft. This includes lithium metal and lithium-ion batteries commonly found in items like laptops, tablets, and smartphones.
What Kinds Of Batteries Does The FAA Allow In Checked Baggage?
The Federal Aviation Administration (FAA) typically permits various types of batteries in checked baggage, as long as they are shielded against damage and short circuits. These batteries encompass non-spillable wet cells (flooded), non-spillable gel cells, lithium-ion, and nickel metal hydride batteries.
However, for safety considerations, spare lithium metal and lithium-ion/polymer batteries, including external battery packs, are not allowed in checked luggage.
It’s also crucial to ensure that battery-powered devices with moving parts or those prone to generating heat are safeguarded from accidental activation.
Additionally, it’s important to note that electronic cigarettes and vaporizers are strictly prohibited in checked baggage at all times.
Any other device containing a battery must be removed from its carrying case, placed in a protective pouch, and carried in the cabin.
Is There A Limit To The Number Of Batteries Or Devices You Can Carry?
When it comes to batteries and devices, there are specific limitations when it comes to air travel. Batteries and battery-powered devices are generally allowed for personal use, including professional use. However, batteries and devices carried for the purpose of resale or distribution by a vendor are not eligible for these exceptions.
For large lithium-ion batteries (101-160 Wh) and non-spillable batteries, there is a limit of two spare batteries.
Moreover, it’s essential that all spare lithium-ion or lithium-metal batteries are individually safeguarded against short circuits.
This means they should either be kept in their original packaging, have their terminals covered with tape, or be stored in a protective pouch or case.
They must also be no larger than 160Wh each or 12g equivalent lithium content per battery.
The same rules apply to devices that use lithium-ion or lithium-metal batteries, with the additional requirement that they cannot exceed 2kg in weight.
