Airport Security Scanners and Batteries

Have you heard the story about the laptop owner who passed her device through a metal detector security scanner?  This was after the security person refused to allow her to use the x-ray, and assured her it was safe. To make double sure she turned the laptop off before she carried it through the metal detector. Then she entered the nightmare world of airport security scanners and batteries.

The Battery Damage Airport Security Scanners Cause

To prove a point, the security person asked the laptop owner to turn it on again after scanning. Everything looked good, with no sign of deterioration.

Two days later, the battery was stone dead despite the fact she had not been using it since.

The laptop BIOS went as far as telling her she did not have a battery installed at all. The most likely scenario is the laptop was close to, and directly opposite, the electromagnetic ray.

The Only Two Work Arounds of Which We Know

We understand and sympathize with the laptop owner. But the security person was only doing what they were told.

What’s more, there are security alerts for laptops, which is why airports insist on using airport security scanners.

Perhaps she could have negotiated removing the laptop battery and passing just it through the x-ray. The other workaround would be to leave the laptop at home, and rent or borrow one at one’s destination.

Can X-Rays Damage Batteries and Electronics

While large x-ray doses can harm living tissue, batteries and electronics are generally immune because they have none at all. The same applies to data, whether on a hard drive, a backup, or a USB. Media players, mobile phones, cameras, and camcorders should also be impervious to x-rays. However, if you are shooting with photosensitive high-speed camera film, have it developed before departing for the airport.

About Author

Electricity has always intrigued me. I have been writing about batteries and energy storage for more than ten years, and have published over 4,000 articles on this website. During that time, I have researched developments across lead-acid, lithium-ion, sodium-ion, flow batteries, and emerging energy-storage technologies. My goal is to explain complex battery concepts in clear, practical language that anyone can understand. My writing career began unexpectedly after leaving the corporate world. What started as a search for a new direction gradually became a fascination with batteries, renewable energy, and the science that powers modern life. Writing may not have made me wealthy, but it has given me the opportunity to explore an industry that continues to evolve in remarkable ways.
