Inogen G4 4 cell battery


The Inogen One G4 Single Battery powers your Inogen One G4 concentrator when you’re away from a power source to give you complete freedom and mobility.

With an extra single battery, you can have a backup battery in place while traveling around town or around the country. Stay active for a longer period of time with your Inogen One! An extra single battery will give you up to 3 hours (setting of 1) of battery life.


There are two Rechargeable Lithium Ion Batteries available for the Inogen One G4 — the Single (4-Cell) Battery and the Double (8-Cell) Battery. Both batteries are designed for use with all InogenOne G4 Oxygen Concentrators.

Inogen One G4 batteries are perfect for trips to the store, seeing a movie, catching a flight, or a dinner out with friends. For longer trips keep multiple batteries on hand to make sure that you can get up and go whenever you want and wherever you want.

Inogen One G4 batteries will charge automatically while in the Inogen One G4 device (when connected to an AC or DC power supply), or using the External Battery Charger. Four LED indicators on the battery indicate current overall charge.
