Lithium Ion Battery
The Efficia DFM100 uses a Lithium Ion battery for power.
A new fully-charged battery, at 20 °C (68 °F), provides power for at least:
Low Battery Conditions
The Efficia DFM100 enters a low battery condition when:
To optimize performance, a battery that is in the low battery condition (less than 40% remaining)
should be charged as soon as possible.
NOTE: The longer the battery stays in the Low Battery condition without charging, the ability to deliver six
full-energy shocks and perform 10 minutes of monitoring diminishes.
With AC power connected and the device turned off, the Efficia DFM100 recharges its battery to
80% capacity in less than 2 hours and to 100% capacity in less than 3 hours. Charge time can be
substantially longer if the device is turned on.

The Power Indicators are located in the upper right corner of the Efficia DFM100's front panel (see
25). The green AC Power Indicator is lit whenever AC power is connected to the Efficia
DFM100, even if the device is turned off.
The green Battery Charging Indicator flashes when the battery is charging. The indicator is solid
green when the battery is fully charged and AC power is present. The light is off if no battery is
installed, the battery is installed but not functioning properly or there is no AC power present.
100 full-energy charge/shock cycles.
2.5 hours of monitoring (ECG, EtCO
sampled every 15 minutes) followed by 20 full-energy charge/shock cycles.
Two hours of pacing (180ppm at 140mA with 40msec pulse) and monitoring (ECG,
continuously monitored and NBP sampled every 15 minutes).
The battery charge is low but contains sufficient power to provide at least six full-energy
charge/shock cycles and at least 10 minutes of monitoring.
The Efficia DFM100 cannot determine the battery's charge level.
