What does a ‘Remove Battery to Cool’ message mean?

This message is displayed on Inogen oxygen concentrators. The concentrators battery has exceeded its charging temperature and charging has stopped. The battery will not charge while this alert is present but will begin to charge when the battery temperature returns to the normal operating range. This helps to prevent any future errors or damage occurring to the device.

If battery charging is desired sooner, remove the battery from the concentrator and allow it to cool in an open area for approximately 10-15 minutes. Then, re-insert the battery into the concentrator. If the message persists the concentrator may need a service.

This is a low-priority alert message and is accompanied by a double beep and a solid red light.
