Inogen One G5 Replacement Battery | 8 & 16 Cell – 8-Cell

This is a replacement rechargeable lithium-ion battery for the Inogen One G5 portable oxygen concentrator, in an 8-cell single battery (Inogen BA-500) or a 16-cell extended battery (Inogen BA-516). It's for G5 users who need a spare or a replacement for a battery that no longer holds a full charge.

Fits: Inogen One G5 and Inogen Rove 6. Inogen sells these batteries as G5/Rove 6 batteries.

Does not fit: Inogen One G4, which uses its own BA-400 and BA-408 batteries.

Which one to choose:

• 8-cell (BA-500): up to 6.5 hours on a G5 at flow setting 1 when new, and recharges in up to 3 hours. The lighter choice for errands and shorter outings.
• 16-cell (BA-516): up to 13 hours on a G5 at flow setting 1 when new, and recharges in up to 6 hours. Better for long days and travel.

Run time is shorter at higher flow settings. The battery charges in the concentrator when it's plugged into AC or DC power, or off the unit with the Inogen external battery charger (sold separately).

Battery life and care: Inogen's G5 user manual gives these batteries an expected life of 500 full charge and discharge cycles. Store a spare in a cool, dry place at about 40 to 50 percent charge, and don't leave it unused for more than 90 days at a time. Keep it away from liquids.

Flying: the Inogen One G5 meets FAA acceptance criteria for use on board aircraft. Check your airline's rules for spare lithium batteries before you fly.
