Tips for Improving Inogen One Battery Life

In order to help your portable oxygen concentrator’s lithium-ion battery work as efficiently as possible, it’s important to understand how to use and care for your battery properly. Here are some tips to help you improve your battery life with proper storage and charging habits.  

Charging Your Battery

Charging your battery correctly can extend the life of your battery over time, allowing it to charge and hold a charge more effectively. 

  • Avoid fully discharging your battery as it puts more stress on the battery
  • Partial charges and recharges are better; aim for 50% battery life before recharging
  • Avoid pushing your battery all the way to 100% every time
  • Discharge the battery fully once a month (or every 30-40 uses) to maintain internal estimates of remaining battery time
  • Only use the provided chargers and charging cords to ensure that your battery charges efficiently
  • Never charge your battery in hot conditions (like a hot car)

Storing Your Battery

Store your portable oxygen concentrator’s battery correctly to avoid damaging it or impacting its ability to hold a charge properly. 

  • Avoid extreme temperatures whenever possible 
  • Do not leave your portable oxygen concentrator battery in a hot or cold car, or other location with uncontrolled temperatures
  • Avoid storing batteries when they are fully discharged to avoid damage to your battery
  • Store your battery with a charge of about 40-50% when possible
  • Do not store your battery with it plugged in to a charging station

Quick Battery Life Tips

When in doubt, just remember the following quick tips to keep your battery working its best!

Avoid:

  • Extreme temperatures
  • Discharging or recharging completely 
  • Storing batteries on less than 40% charge

    This information should be included in the owners manual, as well as the weight of each size battery. It would be nice to find this information easily without scouring the website.

    I've been having my machine for several years and many times have had questions about something I thought of well the answer to any questions was never able to be found because there is no owners manual or if there is one it is not much of a manual.

    Will it harm the battery if we plug in the G5 and as it is recharging unplug it to walk around the house for 10 – 15 mins and then plug it back in?

    1. Inogen Inogen says:

      HI Denise,
      That should be fine. 🙂

    Will the battery charge if the Inogen G3 is turned off but is plugged into the wall charger?

    1. Inogen Inogen says:

      Hi Jayne,
      Yes, it will charge just like a cell phone would. 🙂

    what is the battery life of a double inogen battery at 4 liters?

    1. Inogen Inogen says:

      Hi Larry-
      Please visit the manuals section of our website for the specs on our different units. Generally, the higher the flow setting is congruent with less battery life per charge.

    Can I keep my inogen g4 plugged in to the AC outlet 24/7 while using it in my home?

    1. Inogen Inogen says:

      Yes, you absolutely can.

    Sometimes we switch my sister from her In oven to oxygen tanks. Do I have to unplug the Inogen from the wall outlet?

    1. Inogen Inogen says:

      Hi Dian,
      You don't have to because plugging it to the wall unit helps it charge, but I suggest unplugging it after it is at capacity.

  11. Avatar Diane Martin says:

    Will it harm the battery Of the Inogen 4 if fully charged but left in unit while using plugged in for a long time?

    1. Inogen Inogen says:

      HI Diane,
      You can store the battery inside the unit, but we don't suggest leaving it turned off for long periods of time. Please power it up frequently even if you are not using it.

  12. Avatar Ordella Park says:

    Since Inogen batteries can't touch, how far apart should they be? Thank you.

    1. Inogen Inogen says:

      Hi Ordella,
      Each battery should be in it's own bag (like a ziploc).
      Thank you,

    I am on 2 liters of oxygen, but recently went on a trip with my daughter to a higher altitude. I had to put my flow setting to a 3. I notice that at 3 liters my battery drains a lot faster than if I am at 2 liters. It does not last as long at 3 liters. Is this normal?

    1. Inogen Inogen says:

      Hi Saundra,
      Yes, that is completely normal that a higher flow setting results in a shorter battery performance.
