battery charger by shore power supply or by the generator (selecting the
power source).

WARNING
If batteries are not recharged over long periods of inactivity, they loose
progressively their charge, until they become definitively flat and
irreparably damaged.
S
CAUTION
Always keep the batteries charged and recharge them periodically even
if the yacht is left unattended. If the charge level drops to the minimum,
the batteries can get irreparably damaged. Check each week the
charge status.

DANGER
NEVER clog the air inlets of the cases containing the batteries because
the natural ventilation of the batteries must always be ensured so that
they do not overheat.
S
CAUTION
Monitor the voltage of the batteries. During the charging phase 29.1 V
can be reached, this is a temporary value, well tolerated, both by the
batteries and by the battery charger. This value has to be monitored and
if this situation lasts for too long, the magneto-thermal switches of the
battery chargers must be disconnected.
S
CAUTION
A frozen battery may explode if used or charged; do not start a yacht
with a frozen battery. To prevent the battery from freezing keep it
always completely charged.

DANGER
The battery releases explosive gas: do not approach sparkles or a
flame nor smoke near it. If the battery is used or charged in a closed
area, check for good ventilation. Do not check the battery charge by
short-circuiting the terminals with metal tools: use a density gauge or a
voltmeter.
