Battery Care and Maintenance
Your Inogen One® G4 Lithium Ion Battery requires special care to ensure proper performance
and long life. Use only Inogen One® G4 Batteries with your Inogen One® G4 Concentrator.
Keep Dry
Always keep liquids away from batteries. If batteries become wet, discontinue use
immediately and dispose of battery properly.
Effect of Temperature on Battery Performance
The Inogen One® G4 single battery powers the Inogen One® G4 Concentrator up to 2.7 hours
under most environmental conditions. To extend the run-time of your battery, avoid running
in temperatures less than 41˚F (5˚C) or higher than 95˚F (35˚C) for extended periods of time.
Battery Time Remaining Clock
The Inogen One® G4 continuously displays battery time remaining. This displayed time is
only an estimate and the actual time remaining may vary from this value.
Please Follow These Important Guidelines to Maximize Battery Performance and Life:
• Store battery in a cool, dry place. Store with a charge of 40-50%.
• If using multiple batteries, make sure that each battery is labeled (1, 2, 3 or A, B, C, etc.)
and rotate on a regular basis. Batteries should not be left dormant for more than
90 days at a time.
Battery Charge Indicator Gauge
When the single or double battery is not attached to the Inogen® One G4 Concentrator, you
can check the battery gauge on the battery to determine the amount of charge available.
Determine the amount of battery charge available by pressing the green battery icon button
and observing how many LEDs illuminate.
4 LEDs Light: 75% to 100% full
3 LEDs Light: 50% to 75% full
2 LEDs Light: 25% to 50% full
1 LED Lights: 10% to 25% full
1 LED Blinks: Battery is less than 10% full and needs to be recharged
