Testing The Battery; Recharging The Battery - Covidien Puritan Bennett 560 User Manual

Internal Battery
Warning
Due to its limited internal battery's reserve capacity, the ventilator should only be operated on
the internal battery when no other power source is available. Ensure that the internal battery
never becomes fully discharged.
When the "LOW BATTERY" alarm is triggered, immediately connect the ventilator to an AC
power supply to maintain ventilation and recharge the internal battery.
From the time that an "EMPTY BATTERY" alarm is activated, if no external supply is connected to the ventila-
tor, other alarms may be triggered due to insufficient supply voltage.
In the final discharge phase, the "EMPTY BATTERY" alarm will become continuous, and ventilation may be
interrupted at any time during this phase.
Note:
The "EMPTY BATTERY" alarm symbol may disappear shortly before the ventilator completely stops, but it
always triggers a final, continuous alarm.

Testing the Battery

Your ventilator continuously and automatically checks the state of the internal battery, even when the battery
is not used as the main source of energy. The "BATTERY FAULT1" alarm is activated whenever a problem is
detected in the battery or the charger.
However, on a monthly basis you should disconnect the ventilator from the external power supply to check the
integrity of the connections linking the internal battery to other ventilator components.

Recharging the Battery

In the event that the battery charge level is considered insufficient, as per the reserve capacity display, recharge
of the internal battery is necessary. In general, it is recommended that the ventilator be allowed to charge
when the battery drops below 80%, and that the ventilator be recharged systematically after storage and
before using it again.
Note:
To avoid cycling and extend battery life while connected to an AC power source, the battery will not begin
charging until it has dropped below an 85%-90% charge.
TTo charge the internal battery, do the following:
Connect the ventilator to the AC power source.
