Battery Maintenance

The Battery Pack in the LIFEPAK 9A defibrillator/monitor provides short-term 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 corner of the monitor display during battery charging. A fully depleted Battery Pack is recharged to 90% capacity in three hours, and to full capacity in 24 hours. After full charging, the defibrillator/monitor continues to supply a trickle-charge which maintains the charge on the Battery Pack.
