TSA Bans Lithium-Ion Batteries in Checked Bags Over Fire Risk

If you’re packing for your next flight, take note: the Transportation Security Administration (TSA) has banned lithium-ion batteries from checked luggage due to growing concerns over in-flight fire risks.

That means devices powered by lithium-ion batteries—like laptops, tablets, smartphones, e-readers, power banks, and Bluetooth headphones—must now be packed in carry-on bags only.

These rechargeable batteries are found in nearly every personal electronic device and are known for their efficiency and high energy output. But they’re also sensitive to heat, cold, moisture, and physical damage. If something goes wrong, a battery can go into thermal runaway, a chemical reaction that causes the battery to overheat, catch fire, or even explode.

While rare, such fires are especially dangerous when they occur in a plane’s cargo hold, where detection and suppression are far more difficult—if not impossible—once the plane is in the air. A fire breaking out at 30,000 feet could have catastrophic consequences.

Sharp Rise in Battery Incidents

The decision follows a growing trend of incidents involving lithium batteries. According to CBS News, there was a 42% increase in lithium battery-related incidents reported between 2018 and 2023. These include overheating, smoking, or even catching fire—many occurring inside aircraft or at airport security checkpoints.

Flight crews are trained to manage lithium-ion battery fires in the cabin, where they can quickly respond using fire containment bags and extinguishers, according to Daily Passport. But if a device were to catch fire in the baggage hold, the situation could become far more dangerous.

What’s Still Allowed

Passengers can still bring lithium-powered devices on board, but they must keep them in carry-on bags. The new rule also applies to spare batteries and portable chargers, which have long been subject to special handling rules due to their fire risk.

The TSA reminds travelers to follow these tips:

• Carry all devices with lithium-ion batteries in carry-on luggage
• Keep spare batteries and power banks protected from physical damage
• Turn off devices not in use during the flight
• Never charge devices while in your bag during the flight
• Alert flight crew immediately if you see smoke or smell something burning

Why This Matters

As more people travel with multiple personal electronics, the risk of battery-related incidents has grown. This new TSA rule is designed to reduce that risk and keep passengers safe.

So before you zip up your suitcase, double-check that your phone, laptop, tablet, and chargers are in your carry-on—not your checked bag. It could save you time at security—and help prevent a potentially serious in-flight emergency.
