Worked

It is a little heavier than the original

We got my hubby an Inogen One G4 which advertised a 4.7 hour on setting 2 double battery life, Nope. Closer to 3.45 on setting 2. Jumps up and down by 30 minutes sometimes (according to the app). So to be on the safe side and never caught off guard we purchased several other doubles to try to make sure we always with power. Still haven't figured out how/why the battery life drops and rises like it does, but thankful that he can continue to keep life as normal as possible by being able to get out and about.UPDATE: We've had these long enough to determine that heat and humidity play a large part in the lifespan of the battery. When we are outside and it's hot and humid, the battery life goes down, sometimes significantly, depending on how hard he's breathing. I've since learned to always learned to carry a spare, and we did buy a car adapter so we can get to the car and "plug him in".Issues or not, this is still the best thing ever. We'd both be miserable if he (we) didn't have the ability to get out and about (without lugging tanks). We continue to learn what we can and cannot do, and about how long we can do it, but always carry a spare battery, just in case!!

Fits machine

This is the same battery I got from the company but few dollars cheaper.
