BA-224 (24-Cell Battery), BA-200 (12-Cell Battery) Discontinued
There are two Rechargeable Lithium Ion Batteries available for the Inogen One G2 -- the standard 12-Cell and the extended life 24-Cell. Both batteries are designed for use with all InogenOne G2 Oxygen Systems. When fully charged this 24-Cell battery will last up to 8-hours at an average flow rate of 2. Higher flow settings, such as 4 or 5, will reduce overall battery time by approximately 25%.
