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.

Battery works good my gf is on oxygen and she had the reg battery she got 2 hrs on that on setting 3 now she has extended battery she has gotten up to 7 hrs so far being out from 8 am till 130 pm so I say it’s worth buying cheaper than the indogen site if you can afford it get it

Had it for years now, works great and somehow much less than straight from inogen.

I love this battery!!! I now can do a 3 hr craft group and go shopping without having to recharge the battery. I hate having to re-adjust my activities due to low battery.

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!!

On 3 it last about 51/2 to 6. Hrs. So much easier than carrying 2 or 3 extra batteries

I though it would last longer than it it does

I bought this so I would have plenty of battery power while golfing. I’ve now used it twice and each time I’ve had enough reserve for another 18 if I wanted. I haven’t timed it, but it runs for me probably 9-10 hours at flow rate of 2. It’s a little pricey, but I think it’s worth it.

Very easy to use.
