Official Inogen Replacement Battery — Keep Your Concentrator Running Longer

This is the genuine Inogen standard replacement battery for Inogen One portable oxygen concentrators. Having a spare battery is essential for patients who travel, spend extended time away from AC power, or need to exceed the run time of a single battery.

Stocked and recommended by MyRespCo's Licensed Respiratory Therapist (RRT).

Why You Need a Spare Battery

  • Air travel — FAA requires 150% battery capacity of total flight time
  • Extended outings — day trips, medical appointments, travel
  • Power outages — maintain oxygen therapy when AC power is unavailable
  • Aging primary battery — lithium batteries degrade over time; a spare ensures full runtime

Important Compatibility Note

Inogen batteries are model-specific. Please confirm your exact Inogen model before ordering. Contact us with your device serial number or model number if unsure — our Licensed Respiratory Therapist can confirm compatibility.

Battery Maintenance Tips

  • Fully charge before first use and after any extended storage period
  • Store at room temperature — avoid extreme heat or cold
  • Cycle the battery monthly if not in regular use (charge to full, then run down, recharge)
  • Replace when runtime drops below 70% of original specification
