is intended to provide Astral ventilators with an additional eight hours of power during typical use.
For full details on using the Astral External Battery, refer to the External Battery user guide.

Using the External Battery

Connecting a fully charged External Battery to the Astral device can provide an additional 8 hours of
power during typical use. A second fully charged External Battery can be connected to the Astral device
to provide a further 8 hours of power during typical use. A maximum of two External batteries can be
connected to the Astral device.
Once the External Battery is connected to the Astral device, the DC mains indicator on the User Interface
will illuminate.
Information on system and battery charge levels can be accessed in one of two ways.

1. Battery Indicator

The capacity of the External Battery will be added to the RunTime indicator on the Information bar of
the Astral interface. (this may take a couple of minutes). The total will be the sum of the Astral
internal battery plus either one or two external batteries.
Under normal operating conditions, the ventilator will display:
-
Total system state of charge as a percentage when in ventilation standby mode or connected to
mains power. The battery percentage is an average of all batteries connected to the system. Full
details of individual battery capacities can be reviewed in the information page.

Estimated remaining run time while delivering therapy.
2. Battery information page
The battery information page can be accessed from the device information page. This screen will
display the current charge level (0-100) for any batteries currently detected by the system, as well as
the total system charge.
