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 the perfect power source 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 InogenOne G4 device (when connected to an AC or DC power supply), or using the External Battery Charger. Four lighted indicators on the battery indicate current overall charge.
