Are Alkaline Batteries Allowed on Planes?

Here is a quick guide on whether alkaline batteries are permitted on airplanes since it can be confusing to remember what you can and cannot bring on a flight.

In most cases, it is feasible to fly on a plane while carrying batteries. Although the regulations governing them can be inconvenient, we shouldn’t complain too much since they are in place to ensure the safety of flights. You need to identify what kind of battery you are taking because not all batteries are treated equally.

When it comes down to your typical dry cell alkaline batteries, you can carry AA, AAA, C, D, 9-volt, and button-sized cell batteries. Learn more about airplane batteries in the paragraphs that follow, along with details on power banks and chargers.

Are Alkaline Batteries Allowed on Planes?

Alkaline batteries are about the only way to go when you want to get around to it. Dry alkaline batteries are about the only way to go when you want to get around to it. Batteries such as AA, AAA, C, and D are included in this, along with rechargeable dry batteries. TSA allows dry batteries in carry-on luggage and checked luggage. Since they don’t specify any restrictions, you could theoretically pack as many as you like.

However, according to the FAA, batteries can only be brought for personal use. Accordingly, neither carry-on nor checked luggage containing large quantities that appear to be for resale would be permitted.

Here are other issues with alkaline batteries:

Lithium Batteries on Planes

Are Alkaline Batteries Allowed on Planes?

Lithium-ion battery regulations from the FAA are a little bit more intricate. Check out the differences between Lithium Vs Alkaline Batteries.

These are the types of batteries typically found in laptops, cell phones, tablets, and other small consumer electronic devices. The rules for flying with lithium batteries vary depending on the battery’s watt-hours.

Lithium Batteries With 100 Watt Hours Or Less

As long as they have 100-watt hours or less, lithium batteries are allowed in carry-on luggage. You probably have a lithium-ion battery of this type, but you should always check before taking it off. You are also allowed to bring spare lithium batteries in carry-on luggage as long as they are protected from damage and short circuit.

Lithium batteries with 100-watt hours or less are allowed in checked luggage only when they are still attached to a device. The device must be turned off completely, not just in sleep mode. This implies that you must turn your laptop off before packing it if you must pack it in checked luggage for some reason. There is no room for loose lithium batteries in checked luggage.

However, if at all possible, pack your laptop, tablet, and any other electronic devices in your carry-on luggage. Since the airline won’t take responsibility for items like laptop damage, you don’t want to take the chance of having your laptop stolen or damaged while in transit.

See what kind of devices you can bring on planes:

Lithium Batteries With More Than 100 Watt Hours

You can only pack this kind of lithium battery in your carry-on baggage if you get airline approval ahead of time. In accordance with airline policy, two spares may be packed in carry-on bags, but they must be secured against damage and short circuit.

If lithium batteries contain more than 100 watt-hours, you cannot pack them in checked luggage. This applies to both loose batteries and batteries that are attached to a device.

Lithium Metal Batteries

Batteries made of lithium metal cannot be recharged. As long as each battery has no more than 2 grams of lithium, these can also be carried in carry-on luggage. These kinds of loose batteries are acceptable in carry-on luggage as long as they are shielded from damage and short circuit.

You are also permitted to bring lithium metal batteries in checked luggage if they are in a device. But loose batteries of this type are not permitted in checked baggage.

How Do I Know the Capacity of My Battery?

Well, it’s not complicated; in fact, most of the time, it’s written right there, with the exception of power banks, where it’s more arbitrary. On the other hand, the problem you will face is that very often the information is mentioned in mAh which does not help you much.

So the magic formula to know is that mAh*V/1000 = Wh.

In more concrete terms, if I use my Anker PowerCore 20100 mAh battery (which can charge an iPhone more than 6 times or an iPad Air twice), I’ll never throw it away. I’m just under the cap because it has an output power of 4.8V, which equals 96.48 WH. Before heading to the airport, make sure you have everything you need because even more potent models are now on the market.

Travel with the user manual or any other documentation that demonstrates the power bank’s capacity if it is not stated on the device.

Can You Take a Power Bank on a Plane?

Many of us never leave the house without a power bank, also known as a portable phone charger. It functions as a tiny, portable power source that you can use to recharge your phone or tablet without plugging it into the wall.

In-flight use of these power banks is permitted. If they contain lithium-ion batteries, they must be packed in your carry-on luggage, not checked luggage. This is going to be most of them, so you’re probably better off taking a power bank in your carry-on luggage.

In fact, the TSA website says “NO” to packing power banks in checked luggage, and then clarifies by saying, “Carry-on bags must be filled with portable chargers or power banks that have lithium-ion batteries.”

Our Travel Tips

First of all, use only “quality” Lithium batteries and power banks and if their capacity is not mentioned on them, make a photocopy of any document proving its characteristics (in English of course). A battery in apparent poor condition may also be confiscated.

For batteries (not power banks), pack them in specific boxes so that they do not touch a metal element at the bottom of your pocket or bag. In actuality, it is necessary.

Then, as you will see in the discussion, it’s Russian roulette if you encounter a picky employee (usually because he or she can’t read English).

Beware, however, that an airline is completely free to have a more restrictive policy than the international standards. I, therefore, suggest that you carefully review what your airline says about this. Take Air France, Lufthansa, Swiss, Austrian, Air China, or China Airlines, as examples.

Conclusion: Are Alkaline Batteries Allowed on Planes?

You can take typical dry-cell alkaline batteries on planes. Avoid traveling with any batteries or electronics that have been subject to recalls. Usually, because there are safety concerns, it won’t be permitted on the aircraft.

Additionally, covering the battery’s terminals with tape is a smart move to reduce the risk of a fire starting.


What Type of Battery is Not Allowed in Checked Luggage?

It is not permitted to check luggage with a spare lithium-ion battery that is not attached to a device. When the TSA scans your luggage, they will take this out if they find it.

What Type of Battery is Not Allowed on Airplanes?

Never bring a battery on an airplane that has a capacity greater than 300 watt-hours.
