Can You Bring Batteries on a Plane?
QUICK ANSWER
Yes, you can bring batteries on a plane, and the type decides where they go. Common AA, AAA, and other dry-cell batteries can travel in either carry-on or checked bags. Spare lithium batteries, including power banks and portable chargers, must go in your carry-on, never in checked luggage.
Batteries are allowed on planes, but the rules split cleanly between ordinary household batteries and lithium ones. The concern is fire: lithium batteries can overheat, and a fire is only manageable in the cabin. Here is which batteries go where, and how to pack them so they arrive without setting off any alarms.
Can you bring batteries on a plane?
Yes, batteries are allowed, but where they can go depends on the chemistry. Ordinary dry-cell batteries, the AA, AAA, C, D, and 9-volt alkaline and rechargeable batteries most people use, can travel in both carry-on and checked bags without a quantity limit for personal use. Lithium batteries are handled more carefully. According to the FAA, spare lithium batteries that are not installed in a device, including power banks and portable chargers, are prohibited in checked baggage and must be carried in the cabin. Batteries installed inside a device, like a laptop or camera, can go in either bag, though carry-on is recommended.
Which batteries can go in checked luggage?
Standard dry-cell batteries are the ones cleared for checked bags. Alkaline batteries (AA, AAA, C, D, 9-volt) and common rechargeables like nickel-metal hydride can be packed in checked or carry-on luggage, though the FAA suggests keeping spares in your carry-on to reduce any risk. What cannot go in checked bags are loose lithium batteries, power banks, portable chargers, and spare lithium cells of any kind. Spillable wet batteries, like a car battery, are also banned. The simple rule: if it is a spare battery and it is lithium, keep it with you in the cabin, and if it is a basic household battery, either bag is fine.
What are the rules for lithium batteries and power banks?
Spare lithium batteries and power banks must always fly in your carry-on. Each lithium-ion battery is allowed up to 100 watt-hours (Wh) without special approval, which covers virtually all phones, laptops, cameras, and standard power banks. Batteries between 100 and 160 Wh, found in some professional camera gear and larger power banks, require your airline's approval, and anything above 160 Wh is not permitted. Protect the terminals from short circuits by keeping batteries in their original packaging, taping over the terminals, or using a battery case. If you gate-check your carry-on at the door, remove any power bank or spare lithium battery and keep it on you.
How should you pack batteries for a flight?
A little prep prevents problems at screening. Keep spare lithium batteries and power banks in your carry-on, with each one protected so the terminals cannot touch metal or each other; original packaging, a plastic bag, or tape all work. Put ordinary AA and AAA batteries in whichever bag is convenient, ideally in their retail packaging or a battery organizer so they do not rattle loose. Do not pack any battery that is damaged, swollen, or recalled, since those are banned entirely. Finally, power down devices with installed batteries rather than leaving them in sleep mode, and pack them so they will not switch on by accident in your bag.
Yes, you can bring batteries on a plane. Everyday AA, AAA, and other dry-cell batteries travel in either carry-on or checked bags. Spare lithium batteries, power banks, and portable chargers must go in your carry-on, with terminals protected, because a lithium fire can only be handled in the cabin. Never pack a damaged battery.
