Battery The Battery Pack in the LIFEPAK 9 defibrillator/monitor provides short-term
Maintenance interim power while transporting patients or during other brief interruptions
of ac power. The defibrillator/monitor automatically switches to battery
power if the power cord is disconnected or the ac power source fails.
Warning POSSIBLE DEFIBRILLATOR SHUTDOWN. When operating on
battery power, the large current draw required for defibrillator charging
may cause the defibrillator to reach shutdown voltage levels with no low
battery warning. If the defibrillator shuts down without warning, or if the
LOW BATTERY: CONNECT AC POWER message appears on the monitor
display, immediately connect the power cord to an ac power source.
Recharging Batteries The defibrillator/monitor continually charges the installed Battery Pack
whenever the instrument is connected to an ac power source, even with the
front panel power switched off (although the rear panel ac mains power
switch must be on). The BATT CHRG message appears on the lower left
