I ordered my enogen with 2 of the long lasting batteries. I’m a person who lives in the country and have much work to do outdoors. This gives me the opportunity to get things done. Glad I went with extended batteries to keep on going. I’m not ready to give up yet.

Everything about the G5/Rove 6 Extended Battery
The upgrade frequent flyers buy first
Airlines require battery for 150% of your flight time — a single extended battery covers most domestic routes on its own. On the ground, 13 hours at setting 1 means a full day out (appointments, lunch, the long way home) without watching the gauge.
Fits both generations
The BA-516 16-cell pack clicks into the Inogen One G5 and the newer Inogen Rove 6 identically, and charges from the concentrator’s own AC/DC supply or the optional BA-503 external charger.
Real-world runtimes
Expect roughly 13 hours at setting 1, 10 hours at setting 2, 7 hours at setting 3, and 5 hours at setting 4 (averages; actual time varies with breath rate and conditions). At about 2 lbs, it adds one pound over the standard battery — a trade most users make happily.
