Worth the Cost!!
These double batteries are worth the high cost. The 1st double battery I purchased gave me many more hours of freedom, time away from home, compared to the single battery. The battery lasted for 5 years with good care.I am assuming this new battery will give me another 5 years of freedom! Thank you, Inogen!!

Going strong after a year
I was a little reluctant to buy this rather than a battery from inogen but the cost finally won out. I’ve waited to post this review for one year since purchase. I use my machine all day, every day, so my batteries get a work out. After a year, it’s working perfect. I highly recommend!

Works well!
My portable oxygen concentrator is powered by a single battery, which gives me little more than an hour of supply at my LPM setting, hardly enough to run a simple errand. I purchased this double battery because my oxygen equipment supplier has no intention of stocking them, and now I have at least 3 hours available to me. Delivery was quick and unit performs well.

Great Product. A must for people going out a lot.
After my oxygen setting increased to level 3 the single battery only good for 2 hours 30-45 minute and a bit short for me. I go out a lot, so I ordered this Double Battery. It arrived on time and with excellent instruction to inform me to fully charge the battery before using. I've using it sever times and it last 6 hours and no worry about battery running out and no need to carry an extra single battery and charger.
