Hamilton C2 ventilator Battery 14.4V 6.6Ah 97Wh Lithium Ion Battery REF 369106

► Brief Introduction

HAMILTON MEDICAL recommends that the ventilator’s batteries be fully charged before you ventilate a patient. If the batteries are not fully charged and AC power fails, always pay close attention to the level of battery charge.

Two backup batteries, one standard and the other optional, protect the HAMILTON-C2 from low, or failure of, the primary power source. When the primary power source (either AC mains or a DC power supply) fails, the ventilator automatically switches to operation on backup battery with no interruption in ventilation. An alarm sounds to signal the switchover. You must silence the alarm to confirm notification of the power system change; this resets the alarm. If the optional battery (battery 2) is available and adequately charged, the ventilator switches to this battery first. When battery 2 is depleted or not installed, the ventilator switches to the standard battery (battery 1). The batteries power the ventilator until the primary power source is again adequate or until the battery is depleted. Each battery powers the ventilator typically for 2.5 h.

As a further safeguard, the HAMILTON-C2 provides a low battery alarm. It also has a capacitor-driven backup buzzer that sounds continuously for at least 2 min when battery power is completely lost.

► Specification

5. The listed operating times and conditions apply to batteries revision 3 and later. For earlier battery revisions, the following specifications apply: Operating time with one battery in use (with turbine in use and the following settings: C = 15 ml/cmH2O, Rate = 10 b/min, Pinsp = 10 cmH2O, PEEP = 5 cmH2O): 2.5 h minimum, 3 h typical.

► Replacing the batteries

Open the battery door (3). To remove battery 1 (1), turn the retaining screw until the battery is released. To remove battery 2 (2), press on the tab, and slide the battery out of its housing. Replace with a newly charged battery.

• To ensure that the ventilator always has battery backup, keep locked battery 1 in the ventilator at all times during ventilator operation. Battery 2 may be hot swapped while the ventilator is operating.
