How does TSA detect lithium batteries?

How Does TSA Detect Lithium Batteries? The answer lies in the power of X-rays! Through a process called X-ray absorption, TSA agents are able to identify lithium-ion batteries and remove them for further inspection. When X-rays pass through a piece of luggage, they create an image on the other side.

A: The bags are scanned for security, not specifically for lithium batteries. If you leave a lithium battery in your bag it will travel with you. It is safer for the battery to be in the cabin so that if a thermal runaway occurs the cabin crew can deal with it.

Power Banks and Battery Packs
The airport staff will check to see that your power bank is under 100Wh (watt hours); if it isn't, or is up to 160Wh without prior approval from the airline, it will probably be confiscated. This isn't directly due to any notion that airport scanners damage batteries.

Can you see a tampon during an airport body scan? This is a frequently asked question on Google, and if it's something you're worried about, you can breathe a sigh of relief. Airport body scanners can't see inside the body and therefore can't detect a tampon on a TSA female body scan image.

Airport body scanners alert the TSO to threats—mainly weapons such as knives, guns and explosives. They are designed to detect “metallic and nonmetallic threat items,” according to the TSA. Those are things like explosives or knives made out of materials other than metal, like ceramics, says Malvini Redden.

Methods include: leaving the batteries in their retail packaging, covering battery terminals with tape, using a battery case, using a battery sleeve in a camera bag, or putting them snugly in a plastic bag or protective pouch.
