Inogen 16 Cell Battery

The Inogen 16-Cell Extended Battery (Model BA-516) is a rechargeable lithium-ion battery designed exclusively for the Inogen One G5 and Inogen Rove 6 portable oxygen concentrators. Offering up to 13 hours of runtime at flow setting 1 or 2, it provides nearly double the battery life of the standard 8-cell battery — ideal for all-day outings, travel, and long-haul flights.

Compatible Devices

• Inogen One G5

Up to 13 Hours of Runtime

FAA Approved for Air Travel
Approved by the FAA for carry-on use on commercial flights (approximately 99 Wh energy capacity). Passengers should confirm specific airline regulations before travel.

4 LED Charge Indicators
Four LED indicator lights display the current charge level at a glance, so you always know how much runtime remains before needing to recharge.

Flexible Charging Options
Fully recharges in approximately 3–6 hours via:

• AC (wall outlet) power supply — while inserted in the concentrator
• DC (car/vehicle) power cable — while inserted in the concentrator
