Internal battery
CAUTION
Over time, the capacity of the internal battery will decrease. This depends on
individual use and ambient conditions. As the battery degrades, it could lead to
battery related alarms and or system errors. ResMed recommends the battery be
tested after two years to assess the remaining battery life. Testing and replacement
of the internal battery should only be performed by an authorised service agent.
Note: T
he battery duration depends on the state of charge, the environmental conditions,
the condition and age of battery, the device settings and the patient circuit configuration.
In case of a mains power disruption, the device will op
erate using the internal battery if
there is no external battery connected to the device. The internal battery will operate for
approximately two hours under normal conditions (see “Technical specificatio
ns” on
page 27). The power status of the battery is displayed on to
p of the LCD screen. Check the
battery status regularly while ope
rating the device with the internal battery and connect the
device in time to mains power or alternatively to the external battery.
Additionally the Internal battery use alarm
will be displayed. Press the Alarm mute button
to clear the alarm.
To recharge the internal battery, connect the device to main
s power. It can take up to three
hours to fully recharge the internal battery, however this can vary depending on
environmental conditions and if the device is in use.
Maintenance
The internal battery has to be discharged and recharged every six months.
1 Remove the power cord while the Stellar is turned on (standy-by or in operation) and let
the device operate with the internal battery to a charge level of 50%.
2 Reconnect the power cord to the mains power. The internal battery will be fully recharged.
Storing
If the device is stored for a longer period the internal battery should be at the charge level
of approximately 50% to increase the durability.
Note: Chec
k the charge level every six months, if necessary recharge the internal battery
to a charge level of 50%.
ResMed USB stick
A ResMed USB stick may be used with the device either to help the clinician to monitor
your treatment or to provide you with updated device settings. For more information, see
“Data management” on page 19.
