Battery Time Remaining Clock
The Inogen One® G2 continuously displays battery time remaining. This displayed time is
only an estimate and the actual time remaining may vary from this value.
Please Follow These Important Guidelines to Maximize Battery Performance and Life:
• Store battery in a cool, dry place. Store with a charge of 40-50%.
• If using multiple batteries, make sure that each battery is labeled (1, 2, 3 or A, B, C, etc.)
and rotate on a regular basis. Batteries should not be left dormant for more than
90 days at a time.
