TSA does not require you to remove a laptop battery during screening. Keeping the battery installed in the laptop is fine.

Key points to know:

• Lithium batteries

  • Keep the battery installed in the device whenever possible.
  • Spare lithium batteries (including power banks) are not allowed in checked bags; they must go in carry-on with terminals protected.
  • Typical limits: up to 100 Wh (or 2 g lithium metal) in carry-on without airline approval; 100–160 Wh may require airline approval; over 160 Wh not permitted for passengers.
  • Devices with installed batteries may be checked, but carrying them on is safer and preferred.

• Security screening

  • In standard lanes, you’ll usually remove your laptop and place it in a separate bin for X-ray.
  • If you’re in TSA PreCheck—or in lanes using CT scanners—you may be allowed to leave laptops in your bag. Follow the officer’s instructions at the checkpoint.

• International travel

  • Rules can vary by country, airline, and connecting airports. Check both the departure and destination authorities, plus your airline, before you fly.

• TSA PreCheck

  • You can typically keep your laptop (and small electronics) in your bag, which speeds things up.

Always confirm the latest policies on the TSA and airline websites, as requirements can change.
