InogenExtended (16-cell) Battery - for the Inogen One G5/Inogen Rove 6 - Up to 12 hours, 45 minutes of battery life on setting 1-2.18 lbs.

This was a blessing to have on vacation. We bought it not only for the airline requirement of extra batteries for duration of the flight, but was great to have during our daughter's wedding and reception. Apria messed up and gave us a new Innogen (that obviously hadn't been tested for the ability to charge) the day before our trip and we didn't check it first just started off using the new unit, but found out in Wyoming they gave us one that would not charge at all. Thank God we purchased this battery or my husband would have had to use 0² tanks the whole 2 week trip. Definitely worth the price from just one trip away from home!

Great Inogen Extended Battery!Have had it for 6 months and has never failed. No problems!Fit mi Inogen G 5 perfectly!Run time 6 hours on setting of 2.I am very pleased.I will purchase another one for back up on those real long days!!

I have Pulmonary Arterial Hypertension. This battery was worth every penny. Although expensive, it gives me much more freedom to enjoy life away from the in home concentrator. I had 2 smaller batteries provided by Medicare. I would always have deal with one dying and switching over to the spare. Then I would be forced to leave because that one was running low too.

Works great. Lasts a long time at a great price!

This worked so much longer than the single battery. So happy we grabbed this off Amazon instead of thru the company directly. Great price.

Has great battery life, more that twice the single battery on oxygen setting 2. Only issue is the carrying case is very difficult to close and I fear breaking the zipper.

The battery came in Inogen box. It charged fully and I love having so much time on the battery. Great buy!

Works great! No issues!
