Battery replacement interval
In critical applications it is recom
mended to preventively replace the
battery once a year. This is due to
the difficult to predict combination of
environmental effects and a varying
average solar irradiance per region
and month. In less critical applica
tions once every 2 years is sufficient.
In an ideal situation, where it is con
stantly around 20 degrees Celsius
and where the battery is always at
95%> charge, the battery would be
able to last 3 to 5 years.
When the battery charge had been
drained too far, the Ranos dB will
automatically shut down when the
battery voltage is too low, and once
the battery has charged up enough it
will also automatically start up again.
Battery health
To keep the battery health optimal,
the following is advised:
•
The Ranos dB should not be stored
with a discharged battery, charge
to at least 6,2VDC before putting
the Ranos in storage.
•
Check the battery voltage every
month when storing for a longer
period of time.
•
In normal operation, make
sure the battery is as full as
possible, as much of the time as
possible by optimizing placement.
