Inogen One G3 Standard (8-Cell) Battery - Portable Replacement Battery - Oxygen Accessory - for The One G3 – 1.3 lbs. – 8.75 x 3.0 x 1 in.

I had concerns about the price but they came in bubble wrap no real packaging they all had good charge and are working fine

I’m renting the machine from Apria, but only 1 battery comes with it. When asked thru we’re willing to sell me and extra. Even buying it for Inogen was super expensive. This was the best price around.

I’m very pleased that you carry this battery. It’s a lifesaver for me, and it didn’t take long to get to me. Thank you.

Arrived on schedule. Was definitely an Inogen battery. Inside box was from Inogen. All numbers matched the Inogen battery I had from factory,

Very good

These batteries work great and mine had been mounted to a concentrator before. For the money I bought 2 more because they are factory take offs that work very well at quarter the price of the Inogen store.Use your Inogen G3 to harge them all before you go out.I have a double battery and 3 singles that cost the same as half a double battery. This was a Good Deal.

This is an older model so you call Inogen and all they want to do is sell you a new one. It’s great being able to get parts for the one I have.

My supplier wants over$300 for a battery to fit my portable concentrator. Got it here for $90. When fully charged, gives me 4.5 hours of machine time. Now when I go out, I can breathe for about 9 hours before having to stop for recharge. Works great! Thanks

Llegó en el tiempo esperado. Muy buena compra, rinde igual que las originales pero a buen precio.

I bought a new battery!!!!…. and the item is used looks old and dirty so I’m so disappointed I need my money back
