Inogen Extended (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 works well. It is a large battery and is quite heavy so be aware of that.

Works perfect in my husband’s inogen. Much cheaper than from manufacturer too.

having extra batteries gives you peace of mind, the battery is great!

Works great

Its just a battery

This is the exact battery you can get directly from Inogen and works with the Rove 6. Provides about 6 hours of battery on 5L flow. Takes a couple of hours to recharge. I wish there was an easy way to recharge without having it attached to the portable concentrator. There is an external charger that can be purchased, but it costs almost as much as the battery.

Battery is as advertised, but cost is disproportionately high when compared to to the 8 cell battery.

Fits and works great

it helps a lot ,

I like the double battery as it gives a longer time using my portable oxygen machine. Saves having to take tanks with me. A very valuable piece of equipment!

The product has a 2023 -5 production date, it is still new but older stock. The question of warranty might arise if battery fails and production date is used not date of purchase. Arrived when it was scheduled. It also works fine.
