Frequently Asked Questions
How long does an Inogen battery last per charge?
Roughly 2–5 hours depending on model, flow setting, and cell count — lower flow settings and higher-capacity packs extend runtime. Charge fully before each outing.
How often should I replace my Inogen battery?
Every 1.5–3 years of regular use, or when runtime per charge drops noticeably. Frequent travelers and air users typically cycle batteries faster than stationary users.
Can I carry Inogen batteries on a plane?
Yes — spare lithium-ion batteries meeting airline watt-hour limits are accepted in carry-on baggage. Always check your airline's current policy and keep terminals protected.
