Inogen One G5 8 Cell Battery

I’m sorry to say that right now we have a shortage of batteries and cannot provide any battery sales to our customers. We are not aware of when we will have stock either.   These are the additional or replacement Inogen One G5 Rechargeable Batteries for the Inogen One G5 portable oxygen concentrator system.The new Inogen One G5 delivers the previous Inogen One portable concentrator's independence, but it's smaller, lighter, and makes more oxygen per pound. It's a portable concentrator light enough to be worn care-free by the active oxygen user. That means there are no tanks to refill and no worry about running out of oxygen.The Inogen One G5 is your one solution, your single solution, for oxygen at home or away. The Inogen One G5 is Oxygen. Anytime. Anywhere. Duration Times 8Cell Battery: 1 lpm= 6 hrs 35 min 2 lpm= 5 hrs 03 min 3 lpm= 3 hrs 27 min 4 lpm= 2 hrs 25 min 5 lpm= 1 hrs 51 min 6 lpm= 1 hrs 26 min FREE SHIPPING
