19. BATTERIES
The Sparrow can be configured with two battery options: an internal, re-
chargeable battery pack, and an internal non-rechargeable battery pack.
The battery should be charged or replaced when not in use. For long
storage periods, the battery should not be inserted into the battery
compartment of the ventilator. It is possible to switch between these two
battery options.
