FAQs
Is this battery new, refurbished, or used?
This battery is used. That means it has been previously owned and used with a portable oxygen concentrator. Runtime and cosmetic condition will vary from unit to unit, and you should expect shorter runtime than a brand‑new battery.
What devices is this battery compatible with?
This battery is designed for the Inogen One G5 and is also compatible with the Inogen Rove 6 and OxyGo Next. It is not compatible with the Inogen One G3 or Inogen One G4.
How do I choose between the 8-cell and 16-cell battery?
Choose the 8-cell battery if you want a lighter option for shorter outings and everyday portability. Choose the 16-cell battery if you need longer runtime for travel, long appointments, or more time away from a charger.
How long does each battery last?
Battery life depends on your flow setting, breathing pattern, temperature, and battery condition. Typical maximum runtimes when new are up to 6.5 hours for the 8-cell battery and up to 13 hours for the 16-cell battery, but used battery runtime may be lower.
Is this battery a good option for travel?
Yes, many customers choose this battery as backup power for travel, errands, and long days away from home. If you plan to fly, check the battery specifications and confirm airline rules before traveling.
What should I expect from a used battery?
Used batteries may show cosmetic wear and typically have less runtime than a new battery. They are best for customers looking for a lower-cost backup option who understand that battery performance can vary.
Is this product covered by Medicare or my insurance?
Most of our products are sold as cash‑pay purchases. However, you can request an insurance‑ready receipt from us after your purchase. This detailed receipt includes the information many insurers ask for (such as item description, cost, and HCPCS code), so you can submit a claim yourself and ask your plan about partial or full reimbursement if out‑of‑network or self‑purchase benefits are available.
