The Inogen One G4 Extended Battery powers your Inogen One G4 concentrator when you’re away from a power source. The G4 Extended Battery is a (8) Cell Lithium Ion battery that snaps easily onto your G4 portable oxygen concentrator giving you complete mobility and freedom. It doubles the battery life of the single battery.
Extra batteries are perfect for extending your power to travel or as a backup to your current battery, offering peace of mind. An extra extended battery can provide up to 5.5 hours of battery life (battery life varies depending on setting and breath rate) giving you more power to explore the world around you.
When on vacation, you'll want extra batteries to stay out longer, see more sights, and fly farther on the airplane without having to recharge. Extra batteries add freedom and independence to your life!
