Freestyle 3 Standard Battery
Portable Oxygen Concentrator Battery
The Freestyle Standard Battery is easy to change and offers you up to 2 1/2 hours of battery life (based on a setting of 2). Imagine leaving your home in the morning, visiting friends, doing some shopping, maybe playing with the grandkids, and having a nice dinner out - all without having to plug your oxygen into a wall. Add the optional Desktop Charger for even more flexibility.
Compatible with both the Freestyle 3 and Freestyle 5 POC models
