Caire Freestyle Comfort 16-Cell Battery

The Caire FreeStyle Comfort 16-cell battery delivers roughly double the runtime of the smaller Caire FreeStyle Comfort 8-cell battery, extending your cordless use. At a setting of 2 it provides up to 8 hours of portable oxygen therapy, giving you longer periods between charges. Built for hassle-free mobility, this battery reduces the risk of running out of oxygen and lets you move, travel, and participate in activities with greater freedom.
