MAINTENANCE
Keep the batteries charged (essential to ensure longevity).
It is possible to operate with the battery store charged to 80% on the
condition that the batteries are charged weekly to 100%.
Never run batteries down below 70% of their nominal capacity.
So as to have correctly charged batteries whenever setting out to sea,
take advantage of periods alongside to use the charger or select an
operation mode which enables the generator to function.

A battery monitor (DC meter on the electrical panel) enables control
of the charge, voltage and depletion rate of the service batteries and
of the generator (optional extra).
For its use see the instruction guide.
Always check the battery and charge system condition before you put
out to sea.
Keep the batteries clean and dry in order to avoid premature wear.
Have the acidity level of the battery checked if left unused for a
prolonged period. Check the level regularly.
Tighten and maintain the terminal connectors by lubricating them
regularly with Vaseline.
WARNING
A damaged battery will never recover its original
capacity.
The service batteries should be charged to their
maximum.
