5.11 Using Batteries
Since all batteries, in general, degenerate over time, the recommendations below will ensure
that the battery capacity of the Nippy 4 is maximized during its lifetime.
The internal and click-in batteries in the ventilator are of the Lithium-ion type, which is a
high performance battery. It has a long expected lifetime, low weight in relation to its
capacity and low self discharge.
See the Nippy 4 Service Manual on how to perform service on the batteries.
5.11.1 Power Source Priority
1. AC power (Mains)
2. External DC
3. Click-in battery
4. Internal battery
If the AC power source fails, the ventilator will switch to either the external DC (if installed),
or the click-in battery (if attached) or the internal battery and show a message in the display
window.
