LifeChoice Portable Oxygen Concentrator Battery Level indicators

Understanding the battery level on your Portable Oxygen Concentrator is essential for your health and well being.  You do not want to misread the power remaining on the portable concentrator least you will leave yourself out of batteries, out of oxygen, and out of breath! Today we’ll focus on the LifeChoice Portable Oxygen Concentrator specifically, but understand, the type of read out used on the LifeChoice is pretty standard on the ultra light portable oxygen concentrators.

With so many Portable Oxygen Concentrators on the market today, we will take a close look at the LifeChoice Portable Concentrator by Inova Labs.  The LifeChoice  is in the class of Portable Concentrators we call Compact.  The compact class of POC’s are characterized by a small on-board battery, usually capable of about 2 hours of operation.  These compact POC’s all use some type of supplemental battery, that is either attached directly to the unit, or can be worn around your waist.  The AirSep LifeStyle, Invacare XPO2, and Inova Labs LifeChoice are all examples of compact POCs.

As the most important thing in this class of Portable Oxygen Concentrators is the size and weight under 10 lbs, or just to be one of the smallest and lightest, some sacrifices had to be made as far as output capacity and visual bells and whistles.  For our discussion, the most important items left out of these Concentrators for their considerations of the size and weight was a detailed display of battery life indication.

On the Full Size Portable Oxygen Concentrators SeQual Eclipse 3 for example, there is a LCD display that clearly indicates battery level. You can simply look at the battery indicator and determine if you have 90% battery life or 20% battery life. The same hold true for the Medium Size Portable Oxygen Concentrator from Respironics, the Evergo.  In this case two LCD displays for each on-board battery allows the user to accurately gauge their remaining battery life.

There is nothing wrong with the way the compact Portable Oxygen Concentrators display battery life, you need only know how to accurately read and understand what LED indicators mean.



There are 4 green LEDs used to indicate battery level on your LifeChoice Portable Oxygen Concentrator, one for 25%, one for 50%, one for 75% and one for 100%.  Simple enough, but this is where some confusion may arise.

When the indicators light up all the way to 100%, the unit DOES NOT indicate you have 100% on your battery remaining. What it is telling you is that you have between 76% and 100% on the unit. So you could have all 4 LEDs illuminated, but only have 76% of your battery capacity available to you.

Here is a chart identifying the Life Choice Portable Oxygen Concentrator’s Battery LEDs and the relationship to battery capacity.

  • 25%         Indicator 1 = 0% -25%      Battery Capacity
  • 50%        Indicator 2 = 26% – 50%   Battery Capacity
  • 75%        Indicator 3 = 51% – 75%   Battery Capacity
  • 100%     Indicator 4 = 76% -100% Battery Capacity

Understanding the real battery capacity you have on your POC is vital, I hope you found this FAQ useful.

very well explained. i’ve had this machine for almost 2yrs, and this is the first time I really understood how the batter leds work. Thank You.

Now if I could only find out why the red alarm led starts beeping, even though I still have battery capacity.

Most likely the alarm is beeping for a ‘no breath alarm’. However, the LifeChoice, as the sieve beds start to degrade, will alarm constantly more and more frequently.

The unit will need sieve beds replaced eventually, when they replace sieve beds, the unit gets a software update as well
