Hamilton C1 Ventilator 10.8V 46Wh Lithium Ion Rechargeable Battery REF 369108
The mandatory backup battery protects the ventilator from low power consumption or power outages.
In the event of a power failure, the ventilator automatically switches to battery backup mode without interrupting the ventilation. An alarm will sound to indicate the change. Disable alarms to acknowledge notifications of power system changes and reset alarms.
If the battery is completely discharged, the buzzer will sound continuously for at least two minutes.
The battery charges when the fan is connected to AC power, regardless of whether the fan is on or off. The battery indicator on the device indicates the charge status of the battery.
The battery and power icons in the lower right corner of the screen show the energy consumed. The box around the power icon shows the current fan power.
