How many spare POC batteries can I bring on a plane?

For batteries under 100 Wh (which covers most Inogen and OxyGo single and double batteries), the FAA sets no numerical limit—but you must be able to physically carry them. Use the 150% rule based on your total transit time to determine the exact number you need.

Can POC batteries go in checked luggage?

No. All spare lithium-ion batteries must be in your carry-on baggage. Only the battery currently installed in the device may be in checked luggage (inside the device). This rule is non-negotiable under FAA Advisory Circular AC 120-76E.

🔋 Lithium-Ion Battery Conditioning

For optimal electrochemical performance, new lithium-ion batteries should undergo 2–3 complete charge and discharge cycles before reaching full capacity.

This stabilization phase allows the internal cell chemistry to achieve balanced ion distribution, ensuring maximum runtime, stable voltage output, and extended cycle life.

After this initial conditioning period, no further full discharge cycles are required.
