Batteries

Portable oxygen concentrators run on rechargeable lithium-ion batteries, and run time depends on your flow setting and the battery’s cell count. Here you’ll find replacement and extended (double-capacity) batteries to keep your concentrator powered through longer outings, travel days, or as a spare. We carry batteries for Inogen, Rhythm, GCE and other major POC brands, in new and certified pre-owned condition. Not sure which battery fits your model? Our team can help you match it.
