Product Details

Inogen One G5 Double Battery

Specially made for the G5 Portable Oxygen Concentrator, the Inogen One G5 Double Battery offers double the battery life and double the independence.

It provides up to 13 hours of continuous unplugged therapy — twice the duration of the standard G5 Single Battery.

With such a long runtime, you’ll have fewer batteries to maintain and weigh you down during road trips, long-haul flights, and outdoor adventures. And when the power goes out, you can rely on this lithium-ion battery for uninterrupted oxygen therapy. 

On top of that, the G5 Double Battery offers multiple charging options. You can charge it at home or in the car while inserted in the G5 concentrator.

If you prefer to charge it separately, you can use the optional G5 External Battery Charger. Battery charge time is up to 6 hours with AC or DC power and around 9 hours with the external charger.

Battery Duration

Battery duration listed below are approximate values. Battery duration is affected by a number of factors including operating temperature, battery age, altitude etc.

Setting 1: 13 hrs 
Setting 2: 10 hrs
Setting 3: 7 hrs
Setting 4: 5 hrs
Setting 5: 3.8 hrs
Setting 6: 2.75 hrs

Battery Life Indicator

To check the remaining battery life, simply press the green battery icon button and wait for the LED indicators to light up. The number of illuminated LEDs will tell you the amount of battery charge available:

4 LEDs: 75% to 100%
3 LEDs: 50% to 75%
2 LEDs: 25% to 50%
1 LED: 10% to 25%
1 blinking LED: Less than 10%. The battery needs to be recharged.

Usage Instructions

To replace the battery, press the latch and slide the battery off the G5 concentrator. Then, slide the new battery into the concentrator until the latch clicks.  

Note: When charging a fully depleted battery, the process may start and pause for the first few minutes. 

Battery Care Information

To extend the runtime of the battery, avoid running the Inogen One G5 in temperatures below 41°F (5°C) or higher than 95°F (35°C) for prolonged periods. 

When not in use, store the battery with a charge of 40 to 50% in a cool, dry place. If you have multiple G5 batteries, make sure to rotate the use of each battery regularly and avoid leaving batteries idle for more than 3 months.
