Running the Nippy on Battery Power
Nippy jnr+ may be powered from the mains, external battery or internal battery.
When running on mains, the ventilator will recharge its own internal and/or
external battery. Charge time is normally around 8 to 11 hours, per battery,
depending on the ventilator settings.
Batteries will also be charged when the Nippy is connected to the mains supply
but not running. Leave connected to the mains supply in between periods of use
to keep the batteries charged or to recharge ready for the next use.
When an external battery is connected to a machine, which has an internal
battery, each battery is charged to approximately 90%, starting with the internal
one. Then both batteries are fully charged starting with the internal one. When
the battery(s) are charged, the charge will terminate and the battery will be
monitored to maintain its charge.
NOTE: Basic models, not fitted with the internal battery have no reserve power
unless an external battery is connected.
The ventilator will select its power source, according to the power available, in
the following sequence:-
1. – Mains Electricity
2. - External Battery (if connected)
3. – Internal Battery (if fitted)
In order to save battery power, the ventilator will always run on mains electricity
if it is present.
If the mains fails or is not connected, the ventilator will select external battery as
the next choice. The external battery, if present, will always be run flat before the
internal battery is selected.
If there is no external battery, the ventilator will switch to its internal battery.
If there is no internal battery the ventilator will shut down and alarm.
Battery Run Times
Battery run times are dependent on the ventilator settings and the amount of
leak. High pressures and /or high breath rates use power and therefore shorten
run times. Large leaks use power and shorten run times.
The expected run time can be displayed on screen. Double press the SET
button to display a bar graph of run time. The time for each battery connected
will be calculated, according to the ventilator settings, and shown on the screen.
