Run the ventilator from the battery until the low battery alarm operates and
record the running time. Look up the run time in the table. If the battery is not
achieving minimum run time replace it.
•
If the battery is good, fully recharge it immediately after testing.
•
A run time record is provided at the end of this manual.

Battery Health Quick Test
If it is not practical to check battery run times, a crude quick test may be performed to
identify a battery that is at the end of its life and has not been
noticed by the user or
for a quick check on a battery that has not been used regularly. This test is not an
indication that the battery is good, but is a useful way of identifying
a failed battery.
This test is not intended to replace regular run time testing used to determine battery
state of health.
Quick Test Procedure
1. Remove the external battery from the Aux Power socket if being used.
2. Connect NIPPY+ to mains power supply and fully charge the internal battery
overnight.
3. Turn the NIPPY+ on with the patient circuit fitted to the outlet.
4. Disconnect the mains power supply so the NIPPY+ is running on its internal
battery.
5. Remove the patient circuit from the outlet and allow the NIPPY
+ to ‘free flow’.
This will create maximum flow and load on the battery.
6. If the battery symbol turns red or the NIPPY+ shuts down within 2 minutes the
battery MUST be replaced immediately.
Disposal of depleted batteries
Depleted batteries may be disposed of in line with local authority regulations.
