Ideal for Inogen One G5 portable oxygen concentrators, replacement battery needs, backup oxygen concentrator power, daily outings, medical appointments, travel preparation, home oxygen therapy, and users who need an 8 cell battery for compatible Inogen One G5 systems. Confirm the battery is compatible with the Inogen One G5 before installation — G5 batteries are not interchangeable with other Inogen models — power the device down, and seat the battery according to the manufacturer's instructions, confirming the concentrator powers on and shows the expected charge. Charge the battery only with the Inogen-specified charger or docking method, remember that runtime varies with the prescribed flow setting, and carry a charged spare for outings longer than the battery's real runtime at your setting, as advised by your oxygen provider. Do not use a battery that is swollen, cracked, leaking, or no longer holding useful charge, keep batteries away from heat, moisture, and impact, and store spares at the manufacturer's recommended storage charge in a cool, dry place. Confirm airline lithium battery rules and required spare-battery handling before flying with a POC, and dispose of worn batteries at a battery recycling point per local regulations rather than in household waste.

Very welcoming and informative. We went in to rent a Walker for my mom to see if she would use it. They had no rentals left so he gave us a brand new one on rental. Highly recommend this company for all your ADL needs.

Fantastic service and experience, from delivery to pickup we could not have asked for anything more! We rented a hospital bed, and I do not believe you would get better service anywhere. Highly recommended!
