There are two Rechargeable Lithium Ion Batteries available for the Inogen One G3 -- the Single (8-Cell) Battery and the Double (16-Cell) Battery. Both batteries are designed for use with all InogenOne G3 Oxygen Concentrators.

Inogen One G3 batteries are the perfect power source for trips to the store, seeing a movie, or a dinner out with friends. For longer trips keep two batteries on hand, or use the 16-Cell Battery to make sure that you can get up and go whenever you want and wherever you want. (Fly from New York to London on one battery!)

Inogen One G3 batteries will charge automatically while in the InogenOne G3 system (when connected to an AC or DC power supply), or using the External Battery Charger.

  • Long Lasting Battery

    I received the long lasting battery for my portable concentrator and installed it. It works great and I am able to stay in one place longer without having to charge the battery.

  • 16-cell battery

    So far, no problems. I bought this battery because airlines required a longer lasting battery. The problem was that I expected a faster shipping instead of over a week.

  • 8 hr battery

    Was shipped in a timely manner and seems to be working as expected but we were worried because it took so long to reach 100% - it showed 56% for a long time so we unplugged it and the tried again later - it then started accepting the charge.
