Inogen One G3 Single Battery Pack

The Inogen One G3 single battery is one of the possibilities which you can use with the Inogen One G3 portable oxygen concentrator. More exactly, there are 2 types of batteries: single battery (8 Cell) and double battery (16 Cell).

Even though they are not much different, each of these accessories has its own specifications which make them unique. So, let’s see what makes the G3 single battery different and popular.

Key Features

  • 8.75 inches W x 3 inches D x 1 inches H
  • Weighs 3 pounds
  • Up to 4 hours battery duration
  • Under 3 hours battery charging time (AC or DC power supply)
  • Quick release button
  • Non-slip grip base
  • 83.5 Wh Li-ION Power
  • Battery Time Remaining Clock
  • 90 Day Warranty
  • FAA Approved

Even though the running time of the 8 Cell battery is only half of the 16 Cell battery, the charging time is also half of the time of the double one. Apart from this fact, there is a significant difference in the weights.

The 8 Cell Battery weighs 0.6 kg and the 16 cell weighs 1 kg. So, each user needs to find the best solution for his/her needs. The battery is the most important aspect of each oxygen concentrator. After all, the battery is the part which provides mobility for the G3 users.

The lightest option for your Oxygen Concentrator

As mentioned above, the single battery weighs almost as half as the double battery. The 8 Cell battery weighs 600 grams / 3 pounds and is the lightest option for your concentrator on the market. However, this option (which is much lighter) has a shorter running time.

Battery life / duration

The required time for charging the 8 Cell battery is around 3 hours. After charging the battery, the duration of the battery is around 4 hours. So, if you are planning a long trip, hiking or walking, you may consider the 16 Cell Battery. However, in order to achieve the optimal battery duration, the battery requires special care and maintenance.

The battery life is extended when the device is used at lower settings. More exactly, a lower flow setting doesn’t draw as much electricity. Consequently, the device doesn’t generate much heat and noise. This allows the system components to last longer and don’t wear as quickly as usual.

Effect of Temperature on Battery Performance

The standard 8 Cell pack’s duration is between 2 to 4.5 hours. However, the optimal battery duration is considered in most environmental conditions. To obtain the maximum run-time of the battery, users should avoid temperatures less than 40 degrees F (4 degrees C) or higher than 95 degrees F (35 degrees C).

So, the duration of the temperature is highly dependent on the temperature at which the device is operating. Inogen – the manufacturer recommends not charging the batteries at room temperatures exceeding 75 degrees F (24 degrees C).

Battery Charging

When a battery icon is displayed on the LCD Screen, the battery is operating properly. Unlike the old batteries, the Inogen One G3 batteries can be partially charged or discharged without damaging the whole battery pack.

Initially, the batteries are shipped 40% to 100% charged. This means that the battery can be immediately used. However, it is highly recommended to charge the battery in order to ensure adequate run time.

If you provide the right care and maintenance of the batteries, they will reach around 500 charge/discharge cycles. Afterward, their capacity will retain 80% from the original one.

There are three options for charging your 8 Cell batteries:

DC Power Cord

The DC power cord for Inogen One G3 is the most compatible out of all power supplies. More exactly, this cable doesn’t demand a wall outlet. So, you can charge the batteries using an electrical source in your car, truck or even on a boat.

What’s more, the DC Power Cord can be used while using the oxygen concentrator too. More specifically, you can charge your device while operating. The key factor in this possibility is that the DC Power Cord speeds up the charging process instead of slowing it down.

The DC Power Cord comes with the Inogen G3 Package.

AC Power Supply

Unlike the DC Power Cord, the AC power supply has certain limitations. Yet, this product has remained as the most useful one among users. Even though the AC Power Supply requires a wall electrical outlet, users can charge their batteries while chilling at home or finishing some of their daily tasks.

Unlike the DC Power Cord, the AC Power Supply slows down the charging process. However, it is quite a benefit to be able to charge the device while using it.

External Battery Charger

Apart from the above mentioned, standard chargers, the 8 Cell batteries are compatible with the external battery charger too. The external charger requires a wall outlet. However, once you charge it, the procedure is quite easy.

This charger is extremely useful for users who have purchased more than one battery. They usually use this charger at home and for long trips. When using the external charger at home, users usually try to save time by simultaneously charging two batteries at once.

Battery Time Remaining Clock

In order to track the battery time remaining, the Inogen One G3 constantly displays it. However, note that this device only displays the estimated time and the actual remaining time may vary from this number. In order to avoid running out of battery, you should always check the monitor that displays the remaining battery time.

Also, an option is to carry a back-up power supply. For instance, you can take an extra charged battery or AC Power Supply.
