Learn More About Concentrator Batteries


The replacement batteries we carry are compatible with the CAIRE Eclipse series, SimplyGo Battery, Inogen One G3 8 cell and 16 cell batteries, Inogen One G2 12 cell and 24 cell batteries, Respironics EverGo, AirSep Focus, Invacare Solo, Oxlife Independence and Inogen One lithium ion battery.

We also carry supplemental batteries for some models that don’t house a battery that can be inserted and removed later. The AirSep Battery Belt with Battery is compatible with the AirSep Focus, Freestyle and Freestyle 5, and is plugged into the concentrator when you want to add extra battery life to what is already charged in the concentrator itself. It is worn around the waist and weighs a little under 3 lbs.

The Invacare Supplemental Battery Pack only weighs a little under 2 pounds and supplements the internal battery of the Invacare XPO2. The Lifechoice external battery pack is compatible with the Activox and the Lifechoice concentrators, as well as the Activox External battery.

Extra batteries are good to have, because you never know when you could be out somewhere with a delay in travel, or your car breaks down and you can’t charge your concentrator when you need.
