How to Care for & Maintain Your Concentrator Batteries

Did you know that one of the most important aspects of caring for your oxygen concentrator is properly maintaining the batteries? These important power sources allow your unit to run and if not cared for correctly you risk your unit not working properly, batteries draining far too quickly, or in many cases, your batteries no longer holding a charge! Luckily, there are easy steps you can take to care for and get the longest life out of your concentrator batteries. Keep reading below for more!

Not All Are Equal
The first thing you will want to know is that the batteries that came with your machine are specific to that model. Although the batteries for portable machines are all lithium ion based, they are not universal to every portable machine.

Additionally, it is important to note that amount of battery life given for each battery does change from machine to machine and setting to setting. For example, the battery life, on the rechargeable batteries, for the Respironic’s SimplyGo is roughly 3.5 hours for a full charge. However, that is at an oxygen flow setting of 2. The higher the oxygen setting, the more of the batteries power it’ll require to run, therefore, shortening your battery life.

Store in a Safe Place
When storing your concentrator batteries, it’s important to ensure they are not stored at elevated temperatures. Extremely high and, in some cases, extremely low temperatures can damage your battery and affect it’s ability to hold a charge. Additionally, it’s important to note any increases in elevation as each unit and battery will be functional up until a certain elevation point. To learn the parameters of your individual machine, please consult your owner’s manual. Can’t find it? Click: Download Online Manual(s).

Maintain Your Charge
If you have any spare batteries you’re not regularly using it’s advised to store these batteries at a 50% charge. Not only will this ensure your concentrator will have power should any emergencies arise, it will also help preserve the life of the battery. If a concentrator battery is allowed to drain completely and remain without a charge over an extended period of time, the battery will begin to deteriorate much quicker.

Pay Attention to Battery Life
Most manufacturers list in user manual that batteries are meant to be recharged through their charging cycle, roughly 350 - 500 times before they, unavoidably, begin to loose their efficiency. If your batteries are over 2 years old, pay attention to how long they’re holding their charge. When you begin to notice that the time is getting shorter and shorter for the battery to drain from full to less than half, it’s time to consider ordering a new or spare battery.

Monthly Recalibration
It’s suggested by most manufacturers that you preform a battery recalibration once a month. To do this, ensure all of your AC/DC power cords are removed from the machine. Keep only the replaceable battery on the unit and use the unit as normal until the battery is completely exhausted of all power. You will then want to remove the battery from the unit and refrain from using your unit for one hour. After one hour, charge the battery to 100% full and place back in the unit. Keep an eye on the unit and battery for the next 2 hours to ensure it is functioning properly.

Safety First
Another great safety tip is to always travel with both the internal, supplemental, and/or spare batteries at a full charge if you plan to be gone more than 3 hours at a time. It’s always best to err on the side of caution and not be caught without power in an emergency.

    What about leaving charger on fully charged battery when not in use? Will this hurt the battery?

      Just like any other electronic, it is not good to keep something continuously charging and pulling power. Just like how leaving a laptop constantly charging can eventually damage the components. Leaving your batteries constantly charging is hazardous to the lifespan of the battery.

    Fellow battery-users probably know this, but I've found that having an automobile charging device is not just comforting, it can be critical. When I am driving, I connect the device to continually charge while I am driving. The automobile charging equipment is not that expensive.... the result is super.

    Thanks for this good article. Yep...the main problem with these portables is the batteries don’t last long at all. And anyone who needs more than 2 L pulse has a short battery life. Too bad technology can’t figure out a way to do better.

    Inogen - G-4 battery with extended time. Purchase 3 @$500 each . 2 are still operating and 1 has no life.
    I've charged it and noting happens. Per AMSR, these were purchase 2 yrs - 2mos. I use my POC for flying only. I personally think that the one battery was defective. Hate paying that money and not have it last! Do you think I should speak with customer service from Inogen?

      Thank you for your comment, Margie. Did you purchase your machine through Inogen or our company American Medical Sales and Rentals the Oxygen Concentrator Store?

    We have had a problem with use of our EquinOx car charger in a Chrysler van. Our local mechanic states that the power draw from many portable concentrators' car chargers is greater than the car's electrical system can handle, resulting in blown fuses!

      Thank you for your comment, Linda. This can definitely be the case. If you refer to your owner's manual, it will specify the power output required for charging. Always be sure to refer to your owner's manual if you have questions regarding operating your machine correctly or safely.

      After purchase of Respironics Simply Go and a home unit, I was denied Medicare reimbursement because American Medical Sales and Service is not a Medicare Provider. I wish I had been told that. I am trying to appeal. Any ideas?

    I have an outfit called Lincare that supplies me with oxygen into tanks. they are supposed to get me a portable one, but it is taking a long time, I do not if it's because of medicare issues or what. I am starting to get on their case, so I have to wait. In meantime have you in mind, have to have patience?

    When traveling in my car should I take the battery out of my concentrator before hooking it up to car charge. I have an Eclipse 5 concentrator. Does the car hook up charge the battery . I have battery set on Pulse 6.0
    Thank you for your response to my query

      Thank you for your inquiry, Fred. That depends on the vehicle you are using and it's available power output. Your user manual will indicate the information you need.Feel free to redownload a manual here: https://www.oxygenconcentratorstore.com/portable-oxygen-concentrator-manuals/

    When I purchased my oxygen machine, I was told I didn’t have to unplug my charge that it would not damage anything. Was I misinformed by one of the specialist that I spoke to.

    • Danielle Jason

      That depends on the machine you are using, Teresa. Some machines require a power outlet to run at all times. Most portables do not. Which unit do you have?

    to Mr Hansen - I too have Lincare. I am in south Florida. A word of caution. If you get a "Inogen G4" from Lincare - it is NOT. They get them from another company and "renames" them. I have had one for 3+ years. I am on L3. Only with this unit was I able to go to work every day (8-10 hours). I have 2 #8 batteries, 1 #16 + 1 charger that I could plug in and charge while using a different battery. Lincare's service here is HORRIBLE. THEY DO NOT HAVE A BACKUP AVAILABLE - so if the unit breaks, you are out of luck - they will only offer you tanks - which I have never used. I lost my job 2 years ago because I did not have oxygen (mine was out being fixed because it kept overheating) and the company where I worked would not allow tanks in the building. It is a great machine, and certainly gave me the freedom not to be homebound. I would change to another company that would support the equipment before I ordered it. Your insurance company should be able to help you find another company(besides Lincare) in your area.
    Good Luck
