Internal Battery
The device contains an internal battery that can be used as a back-
up power source. It is intended for use during short periods while
switching between external power sources, emergency situations, or
short durations when the user needs to be mobile. The length of time
the ventilator will operate on internal power depends on many factors
such as device settings, battery charge level, and condition or age of the
battery. When fully charged, a new battery can power the ventilator for
approximately three hours under typical patient conditions.
Whenever the ventilator is connected to AC power, it will
automatically recharge the internal battery. A completely discharged
internal battery will reach 80% charge status within 8 hours when
charging at approximately 23˚ C (73 ˚ F) ambient temperature.
