Battery Maintenance
When you receive a new battery:
•“Wake it up”
• Charge it and start rotating
• Familiarize yourself and the user with the HeartStart XL+ Lithium-Ion Battery: Characteristics and
Care Application Note (available in various languages).
“Waking Up” a Battery
Your HeartStart XL+ lithium-ion battery is shipped at about one-third of full charge and in a “shutdown”
or “sleep” mode to extend battery shelf life. In this mode the power is not delivered, and the fuel gauge
lights do not light up, until the battery switches into the working mode.
To transition a new battery into the working mode (wake up a battery):
1 Insert a new battery in a HeartStart XL+ defibrillator/monitor.
2 Plug the device into AC power.
When the Battery Charging light starts flashing, the battery is in the working mode.
3 Continue charging, or you may start using the battery for therapy if needed.
Once in the working mode, the HeartStart XL+ lithium-ion battery cannot be returned back to the sleep
mode.
Battery Calibration
Calibrate the battery when any of these conditions occur:
•the Battery Calibration Required Technical Alarm appears
• Op Check Battery Test results in Calibration Required
•the Replace and Service Battery Op Check message appears
• six months pass after previous calibration.
Calibration of a fully charged Battery may take up to 11 hours to complete.
TIP: To reduce calibration time, charge the Battery before calibration. The Battery charges faster when the
HeartStart XL+ is turned off.
NOTE: Running a calibration cycle at temperatures above 30°C (86°F) or below 10°C (50°F) increases the
chance of a calibration failure.
If during Battery calibration your device becomes needed for clinical purposes, use the Exit Calibration
and then Exit Service soft keys. Repeat the Battery calibration later. After the initial charge phase, the
Battery charge level never falls below 60% during calibration.
To calibrate a Battery:
1 Insert the Battery that needs calibration into the Battery compartment.
2 Connect the AC power.
3 Access Service Mode (see “Accessing Service Mode” on page 8).
4 From the Service Mode Main menu, select Battery Calibration and press the Menu Select button.
The Battery Calibration main screen is displayed, see Figure 12:
