It came all most fully charged. First use it lasted 4+hours on 4.it looks new but no inogen package. Delivery was fast

### ⭐⭐⭐⭐⭐ Worth the Cost!!
*by K***N on May 11, 2025*

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!!
