2.7 Battery Condition
The CoMo AV uses two AA-cells. The battery-state-indication and
battery-info-page keeps you informed about the battery condition.
The battery-info-page shows on the left the actual voltage. New
cells should provide at least 3.2 V. If voltage falls short of 2.2 V,
cells should be changed.
Next to it is a meter for operating-hours. The percentage-
indication converts the voltage into an easily understandable
percent-value.
Any kind of battery state indication will be affected in cold
conditions when battery cells and accumulators suffer a
considerable loss of capacity.
E.g. a pilot may take off at 20 °C with the instrument indicating
a capacity of 40 % only to find it soon afterwards reduced to 5
% at a temperature of -10 °C at 4000 m MSL...
Apart from competition flying, Alkali-Mg cells should work very
well. To ensure satisfactory operation in low temperature
environment (winter flying or high altitudes) 1,5 V Lithium cells
can be used as well (www.energizer-eu.com). Our Solar-Module
represents the ultimate solution (appearing summer 2008).
If voltage drops below 2.2 V, the GPS is turned off, but the audio-
vario-function is maintained. In this case it is high time to change
batteries.
