Check Battery – Inogen One G3

Is your Inogen One G3 showing a “Check Battery” error message? If so, you should follow the troubleshooting steps found in the Inogen One G3 User Manual. You may find that it is time to replace your battery with a new one.

An Inogen One G3 battery will power your Inogen One G3 concentrator. It’s very important that you have a battery that is in good condition, and even better if you have backup batteries available.
