Checked Bags: Yes in the most common sizes: AA, AAA, C, D, button cell, 9-volt, etc. Batteries must be protected from damage and creating sparks or a dangerous evolution of heat. For more information, see the FAA regulations on batteries.
◾ Batteries: Regular AA and AAA batteries are fine in either checked or carry-on bags, but most devices that use lithium-ion batteries like cellphones and smart luggage have to be brought into the cabin. The batteries can be a fire hazard in the cargo hold.
Batteries in portable electronic devices (for example laptops, electric toothbrushes, handheld gaming devices) may be kept in checked luggage under some conditions. You should ask your airline when you check in. You must carry all spare or loose batteries in your carry-on baggage only.
Most consumer personal electronic devices containing batteries are allowed in carry-on and checked baggage, including but not limited to cell phones, smart phones, data loggers, PDAs, electronic games, tablets, laptop computers, cameras, camcorders, watches, calculators, etc.
The AAA Battery is a small cylindrical cell battery of alkaline, lithium, or Ni-MH composition. The AAA Battery is an extremely common battery and is produced by many large brands such as Duracell, Atomic, Energizer, Toshiba, and more.
Typically the first letters in the alphanumeric code will identify the type of battery. The first letters (LR) indicates an Alkaline battery and may be thrown in the trash. Batteries with the first letters (CR) indicates a Lithium battery, (SR) indicates a Silver Oxide which contain heavy metals.
They're ideal in smoke alarms, for example, where the average power draw is very low and where extreme long-term stability is key. AA lithium cells have a shelf life of up to 9 years, and they can last a far longer time than most other AA types in the right sorts of devices.
The Federal Aviation Administration rules permit devices with lithium batteries installed in checked bags as long as they are powered off and can't be accidentally powered on.
Anything Flammable
Flammable items aren't allowed in your checked baggage or carry-on. This includes paints, gels, and liquids. It's for everyone's safety.
Spare batteries and power banks, however, always have to be transported in your carry-on baggage - never in your checked baggage - and they must be individually protected to prevent short-circuits. E-cigarettes must always be in your hand baggage.
A certified AAA emergency Roadside Assistance technician will come to you and test your battery with state-of-the-art technology.
Spare larger lithium-ion batteries and power banks (101-160 Wh) are forbidden in checked baggage.
Portable chargers or power banks containing a lithium ion battery must be packed in carry-on bags.
Duracell High Power Lithium batteries have up to 10 years in storage guaranteed so you can be confident these batteries will be ready when you need them. Long-lasting Power, Guaranteed.
Travel Tip: Put an Apple Airtag in your checked luggage so that you can track it and don't have to worry about the airline loosing it. 😉 After having to deal with the airline loosing my luggage more than once, I now put an Apple AirTag in my luggage before checking in it. Highly recommend 10/10.
Good news! Most are allowed in carry-on or checked bags depending on the type of product and if they are battery operated. Battery operated toys that use traditional non-rechargeable batteries (AA, AAA, etc.) can go in checked or carry-on bags.
We recommend packing all liquids, gels, and aerosols that are over 3.4 oz or 100 ml in your checked baggage, even if they are in a secure, tamper-evident bag. Liquids more than 3.4 oz or 100 ml not in a secure, tamper-evident bag must be packed in checked baggage.
Each passenger is limited to one quart-size bag of liquids, gels and aerosols. Common travel items that must comply with the 3-1-1 liquids rule include toothpaste, shampoo, conditioner, mouthwash and lotion.
Electronic devices that can be carried in cabin baggage
In addition, devices like power banks, trimmers with batteries, and chargers can be carried with you. Interestingly, devices like wireless routers, desktop PCs, CPUs, and monitors cannot be carried in checked-in baggage.
Checked Bags: Yes
Batteries must be protected from damage and creating sparks or a dangerous evolution of heat.
Alkaline AAA batteries weigh around 11.5 grams (0.41 oz), while primary lithium AAA batteries weigh about 7.6 g (0.27 oz). Rechargeable nickel–metal hydride (NiMH) AAA batteries typically weigh 14–15 g (0.49–0.53 oz).
Spare (uninstalled) lithium ion and lithium metal batteries, including power banks and cell phone battery charging cases, must be carried in carry-on baggage only. Lithium metal (non-rechargeable) batteries are limited to 2 grams of lithium per battery.
AA batteries measure 14.5 x 50.5 mm, while AAA batteries measure 10.5 x 44.5 mm. This size difference results in a major variation in volume. AA batteries have approximately 8.3 cm³ (0.506 inch³), whereas AAA batteries have about 3.8 cm³ (0.232 inch³).
CHECK FOR MARKS AND SYMBOLS Battery labels help you determine the type of battery (Li = lithium and Pb = lead), and lithium battery labels can be a different color than their lead battery counterparts.
Lithium-ion AA Batteries
They use lithium combined with other compounds and power most electronics today, including laptops, cell phones, and tablets. On the other hand, AA lithium batteries (non-ion) are meant for quick and powerful bursts of energy but aren't designed to be recharged.
