HeartMate Universal Battery Charger IFU 22
calibration ends may result in a depleted battery (the on-battery fuel gauge will
reflect this status).
Note
: It is important to calibrate a battery as soon as possible after being prompted
to do so. This helps ensure the best possible battery performance. Be sure to have
enough charged batteries when planning for calibration, which can take up to 12
hours. For example, under normal conditions, having four charged batteries will
allow you to exchange batteries twice during a 12-hour calibration cycle.
Follow these steps to calibrate a HeartMate 12 volt NiMH or 14 volt Li-Ion
battery:
1
Receive a calibration prompt from the charger (blinking yellow light,
broken battery symbol on display panel screen) (
Figure 18
).
2
If you do not want to calibrate the battery now, do nothing. After ten
seconds, the UBC will continue to charge the battery as usual (see Section
3.2,
Charging Batteries
).
OR
2
If you do want to calibrate the battery now, within ten seconds of the start
of the blinking yellow light, press and release the number button for this
pocket.
Note
: During calibration, the yellow light for this pocket remains on and
“HeartMate CHARGER” appears on the display panel screen, unless the
number button for this pocket is pressed. Pressing the number button
during calibration brings up the calibration status screen for the battery
(
Figure 19
). Once calibration is complete, the yellow light turns off and
the green light comes on. Green means the battery is charged and ready for
use.
CAUTION!
Leave a calibrating battery in the Universal Battery Charger for
the entire calibration cycle. Removing the battery before it is fully calibrated
may result in a depleted battery (the on-battery fuel gauge will reflect this
status).
