Travelers using personal electronics on flights in 2017 relied on lithium batteries packed in both carry ons and checked bags. The Transportation Security Administration issued specific guidance that year to clarify screening procedures and safety expectations for these power sources.
As air travel security evolved, the 2017 rules emphasized consistent packing, device accessibility, and strict limits on spare batteries. This article explains what the TSA required for lithium batteries in 2017 and how passengers could comply without delays.
| Category | Carry On Luggage | Checked Luggage | Key Notes |
|---|---|---|---|
| Lithium metal batteries | Allowed, must be accessible | Restricted or prohibited | Spare cells limited to reasonable quantities |
| Lithium ion batteries | Allowed in devices and as spares | Limited, often prohibited in checked bags | Maximum size and quantity limits applied |
| Installed batteries in devices | Remain in device during screening | Generally permitted with packing limits | TSA requires easy access for inspection |
| Power banks and portable chargers | Allowed in carry on, must be declared | Often not allowed | Capacity labeled, no damaged units |
Carry On Rules for Lithium Batteries 2017
Accessibility During Screening
In 2017, the TSA required passengers to remove laptops and large power banks from bags and place them in a dedicated bin for X-ray screening. This step reduced manual checks and kept the line moving.
Quantity and Size Limits
Carry on lithium batteries were limited to those needed for personal electronics. Spare lithium ion cells had to be under 100 watt hours, with airline approval required for larger units.
Protection Against Damage
Passengers were instructed to protect terminals using original retail packaging, cases, or tape. Preventing short circuits was a central concern for both the TSA and airline crews.
Checked Bag Policies and Exceptions
Prohibition on Spare Batteries
Most spare lithium batteries were not allowed in checked luggage by 2017 standards. The risk of fire without immediate access led security to mandate carry-on storage for critical spares.
Installed Batteries in Devices
Devices with lithium batteries already installed, such as cameras and medical equipment, could be checked if securely packed. Gate agents and screeners retained the right to remove items if safety concerns arose.

Variations by Airport and Airline
While TSA set the baseline rules, individual airlines and foreign airports applied their own limits in 2017. International travelers were advised to verify specific requirements for each destination and carrier.
Documentation and Labeling
Power banks and larger lithium packs often required visible rating labels in 2017. Clear markings of capacity in watt hours helped screeners quickly validate compliance and prevent unnecessary confiscation.
Practical Tips for Flying with Lithium Batteries in 2017
- Keep batteries and power banks in carry on luggage only, whenever possible.
- Place loose batteries in a dedicated, clearly labeled pouch.
- Verify watt hour ratings and airline policies before travel.
- Protect terminals to prevent accidental short circuits during handling.
- Be ready to remove devices and batteries quickly during screening.
- Check updated guidance at the airport before departure.
FAQ
Reader questions
Can I bring a portable charger on a domestic flight in 2017?
Yes, you can bring a portable charger in your carry on as long as it is labeled with its capacity in watt hours, is in good condition, and does not exceed airline limits. Keep it accessible during screening.
How many spare lithium batteries can I carry in 2017?
You may carry only the spare lithium batteries you need for your trip, typically limited to those under 100 watt hours without special approval. Larger quantities usually require airline authorization.
Do I need to remove my phone from its case during screening in 2017?
Phones may be left in their cases, but you must remove them from thick sleeves or bulky accessories that could obscure the X-ray image. The device itself should be clearly visible on the screening belt.
What happens if my lithium battery is swollen or damaged at the checkpoint in 2017?
TSA officers will not allow swollen or damaged lithium batteries in either carry on or checked bags. You will be required to dispose of the item before proceeding through security, often through a designated receptacle.
