HeartMate III Left Ventricular Assist System Instructions for Use
7-13
No External Power Alarm
The 11 Volt Lithium-Ion backup battery inside the System Controller provides power to the Pump
for at least 15 minutes when fully charged if the main power source is disconnected or fails.
Refer to
System Controller Backup Battery Power
on page 2-36 for details about the 11 Volt
Lithium-Ion backup battery inside the System Controller.
IMPORTANT!
If external power is not restored, the Pump gradually slows to the Low Speed Limit
to save power in an effort to prevent the Pump from stopping. When adequate power is supplied,
the Pump reverts to the previous speed and the red battery alarm clears.
