Troubleshooting LifeChoice Portable Oxygen Concentrator Tripped Battery Circuit

LifeChoice Portable Oxygen Concentrators have a feature that is unique among all other portable oxygen  concentrators.  Built into the supplemental battery of each Life Choice portable oxygen concentrator is a surge protector.

The concept is great, who would not want to protect their $4000 POC from a power surge that could fry the complex electronics that operate this five pound wonder?  By design, the engineers at Inova Labs built an electronic switch into the LifeChoice battery to cut power to the LifeChoice Portable Oxygen Concentrator should external current exceed limits, or the internal draw from the unit exceed the capacity of the battery.

Anyone who uses a LifeChoice Portable Oxygen Concentrator should be aware of this feature and know how to reset the battery if the mechanism was tripped.

Two things we always teach our Life Choice customers,

  1. Never turn your LifeChoice Portable Oxygen Concentrator on with a cannula attached and in your nose
  2. How to identify and reset a tripped battery circuit.

In case you were never told or forgot the way to identify if your battery surge protector has been tripped, or how to reset your battery if the surge protector was tripped, follow these simple instructions.

How To Identify If Your Lifechoice Portable Oxygen Concentrator has a Tripped Battery Circuit

1) Plug the LifeChoice Supplemental battery into the POC, look for solid green light on LifeChoice Battery Indicator.

You should see a solid green light on the Battery Indicator LED.  WHENEVER YOUR LIFECHOICE PORTABLE OXYGEN CONCENTRATOR IS PLUGGED INTO AN EXTERNAL POWER SOURCE (AC Adapter, DC Adapter, or Battery) the Battery Indicator LED will be illuminated SOLID GREEN and NOT FLASHING.

If you have an external power source attached to your LifeChoice Portable Oxygen Concentrator, and the Battery Indicator LED is not solid green, that external power source is not supplying power to the POC.

If your AC Adapter or DC Adapter light is on, you know you have power to the adapter. If you press the yellow battery indicator button on the LifeChoice Portable Oxygen Concentrator supplemental battery and the indicator lights illuminate you know you have power in  the battery.

But, if you attach the supplemental battery to the LifeChoice Portable Oxygen Concentrator, and the Battery Indicator on the POC is not SOLID GREEN, your battery circuit has been tripped.


First, and most importantly, unplug the external battery from the LifeChoice Portable Oxygen Concentrator!! If the battery is not unplugged, the reset will not work. Undo the Velcro all along the battery, and pull the battery out of the case.

At the top of the battery, where the wire comes out of the case, you will see a glowing RED LED.  That LED only glows when the circuit is tripped, but it can be difficult to see inside the case.

On the same side of the circuit board as the RED LED, about one inch away, is a small red reset button.  PRESS THE RESET BUTTON!!

Put the battery back in the case, close the Velcro, and plug the battery into your LifeChoice Portable Oxygen Concentrator.  You will now have a SOLID GREEN LED on the LifeChoice Portable Oxygen Concentrator Battery Check, which means the LifeChoice is now operating again, on external power.

I bought my LIFE CHOICE ACTIVOX pro new Jan 20 2015. It was working great until now. What happens is after it runs for around a1/2 hr. the yellow alarm light comes on. I shut it off and after 10 seconds turn it back on. Again it runs OK for 1/2 hour sometimes longer then on comes the yellow alarm light again. I was told by the salesman to run it every day for at least an hr. It has not been abused in any way. I have been very careful handling it. I has been set 2 feet above the floor and open on each ends so that it can breathe. I had an older version that went haywire almost the same way. They talked me into buying this newer version by trading it in saying it would be much better. They want $400.00 just to look at it plus postage both ways. I don’t know if you can answer this but thought you could give me some ideas. Also I did try setting it back to factory default. by holding the on button on for 10 seconds but that did not help. I am a retired person so every penny counts. Do you have any ideas Also it still has the warranty’s. THANK YOU Robert Baumann

BS, you are dealing with a crappy provider. Warranty service, and that unit is under warranty is free. Problem with dealing with some of these internet providers, the two largest volume dealers are the two worst offenders.
You should have them send you a free loaner while they send your unit in for repair.
Your unit is under full warranty for the first year, then 3 year limited after that. Inova is a good company with their patients, make sure you let them know the BS the company is giving you. Then, write on social media and yelp about their crappy service.

The alarm and red light comes on whether I have it plugged in at home or in my car while traveling. It is really annoying. It cost a lot of money and hasn’t been very good. I spent another $200 getting it repaired recently. I finally purchased a home type for my cabin in Montana and have one on lease at my home. They both work great! Not so with my portable unit that cost 3 to 4 times as much. I am very disappointed.
