14.1 The internal battery
The iris EFIS has a Li-Ion internal battery, used for powering the unit, if the main power supply
of the plane gets cut, during flight.
The internal battery can power the iris EFIS from 3 to 5 hours , depending on the brightness
level, whether wireless is on, and the volume.
To extend the longevity of your iris EFIS’ battery a few key steps should be taken:
• Avoid using the internal battery, when not needed - Do not intentionally cut the power to
the iris EFIS, when there is still enough power from your main batteries. Do not intention-
ally leave it in flight mode.
• Avoid draining the internal battery - Draining the battery completely is a known culprit
for reducing battery capacity. If you see the iris EFIS changed to its internal power supply,
think about heading to your home airfield.
• Proper winter storage - During periods of long inactivity, especially during winter, when
cold temperatures are present, the battery capacity is lowered by cold temperatures and
it can easily happen that the battery gets completely drained causing the iris EFIS to lose
part of its capacity. To avoid this from happening, it is recommended that, whenever the
iris EFIS is in storage, it should be connected to an external power supply regularly, every
4 to 6 weeks, for at least 3 hours, for the internal battery to charge.
NOTE
The iris EFIS can not power external devices, while on internal power, meaning
Flarms, User port connected PDA/PNA devices and CAN connected devices will
stop working (unless they have an internal power supply of their own.
NOTE
The iris EFIS charges the internal battery automatically, when connected to an
external power supply.
