Portable Oxygen Battery Buying Guide
One of the most important things about your portable oxygen concentrator are the batteries. All batteries that are made to specifically fit each model, so you will need to buy any replacement batteries accordingly. At full charge, your battery should give you enough time to explore, travel and take a shopping trip, untethered to an external power source. These are essentially what makes your portable oxygen concentrator your ticket to freedom. It's important to compare the life of the battery for each model, as well as the prices when buying a portable oxygen concentrator.
Purchasing an external or replacement battery, besides the one that came with your concentrator, is important. Having an extra, fully charged battery with you on trips is always a good idea. Not only do most airlines require that you bring an extra fully charged battery with you on a flight, but you never know when you could get stranded, have to wait for transportation, or experience a power outage.
Inogen 12-cell and 24-cell – When buying an Inogen One G2, you have two different options for battery size and life. One 24-cell Lithium-Ion battery will stay charged enough to run the concentrator, for 6 to 8 hours, depending on the flow setting, and the 12-cell for 3 to 4 hours at a time. The 24-cell battery is larger and heavier than the 12-cell, as well as more expensive.
Inogen One G2 External Battery Charger – This charger will only charge the external 12-cell and 24-cell batteries for the Inogen One G2. It takes 3 hours for it to charge the 12-cell battery, and 6 hours to charge the 24-cell.
Sequal Eclipse Replacement Battery – Also called the replacement power cartridge. These can be quickly switched out so that the other can start charging while the first is being charged. You can expect between 1 to 5 hours of battery life, depending on the flow setting.

Lifechoice External Battery Pack – The internal battery of the Lifechoice will last for around 2 hours, but, you will have an addition 3 hours (on any setting) with the external battery, which can be worn inconspicuously around your waist while it is hooked up to the concentrator.
Invacare XPO2 Supplemental Battery Pack – Adds 2.5 hours of battery life onto the internal battery of this model. It weighs little more than 1 lb, so you won't even notice that it's there.

External Battery – A battery that can be charging outside of the concentrator on a charger, or while attached to the concentrator and plugged into a power source.
How to Choose a Concentrator Battery
Look at how long a battery will last and ask yourself if this is the right amount of time for you, depending on what you want to do. If you want to take long trips between charges, select a model with a battery that lasts longer. Keep in mind that most of the time, a longer lasting battery will cost more, but it's worth it if you need it.
If you are traveling outside the country, be sure to purchase an adapter that will be compatible with outlets in whatever country you will be traveling to. An automobile outlet adapter is needed for long road trips, and is a good thing to have in case you need it.
