Battery Replacement
•
Battery operating times will degrade with battery age, number of charge cycles and operating
environment. While it is not uncommon for batteries to last more than two years, it is recommended
that battery capacity be evaluated after two years of device use and replacement considered.
Any battery with a capacity of less than 70% or less than 4,480mAh should be replaced. Battery
capacity readings can be accessed using the device serial number on the O2 Concepts

Air Travel
•
The Freedom is an approved portable oxygen concentrator as indicated by the requisite FAA
statement on the rear label. Please note that many air carriers require prior notification (usually at
least 48 hours) for passengers traveling with portable oxygen concentrators. Not all air carriers
provide an electrical outlet on board the aircraft, so the patient should have sufficient batteries (or
confirmed alternative power source) to account for at least 150% of your total travel time,
including, but not limited to: (A) commuting time to and from the airport; (B) transition time in and
out of airports; (C) the duration of your flight; and (D) any unexpected delays. Please be aware
that battery requirements may vary based upon Freedom use at the prescribed flow rates. Use
requirements may also be affected by the aircraft cabin environment.
