3-7-3-2 Charging the Battery
1) Place the battery into the battery bay making sure that the 5-way connector is fully seated.
The LEDs in the status window (see Figure 3-56) will provide status information as detailed in
Table 3-3 below, and the charger will automatically begin to charge the battery.
• Recharge Time:
The time for a full charge from 0% to 100% state of charge is typically 4.5 hours.
• Recalibration Time
The recalibration cycle begins by discharging away any residual capacity. Then a calibration
charge is delivered to the battery. This is followed by a calibration discharge. Finally the
battery is given a regular charge. A calibration cycle will be faster if the battery is fully
discharged to begin with.
The recalibration time is approximately 9 hours for an empty battery, and approximately
14 hours for a fully-charged battery.
NOTE: Calibration is initiated each time the button is pressed, so it is not recommended to press the
recalibration button part way through the recalibration cycle.
During the charging procedure, the green LED will be seen flashing.
At the end of this procedure, when the battery is fully charged, the solid green LED will be
illuminated in the status window, indicating a fully charged battery.
2.) Remove the battery from the charger unit battery bay and install it in the
Vivid q N portable ultrasound scanner.
