The batteries are normally charged by the alternators during the operation of the engines. As an alternative, you can recharge them with the battery charger from shore or with the generator.

The batteries left unloaded over long periods of not operation, loose progressively their charge, until they become completely flat and get irreparably damaged.
Any replacement of the battery bank dedicated to the bow thruster is only to be carried out with sealed VRLA-type batteries.
If the engines are ON; it is advisable to keep the thermal switch of the battery charger to OFF, in order to avoid alternator damage.
NEVER obstruct the air intakes of the cases containing the battery boxes as natural ventilation must always be allowed so that the batteries do not overheat.
Do not lay objects on the cases containing the batteries.
A frozen battery may blow up if used or charged; do not start a Yacht with frozen battery. To prevent the battery from freezing keep it always completely charged.
The battery releases explosive gas: do not approach flames, sparkles or smoke near it. If the battery is used or charged in a closed area, ensure ventilation. Do not check the battery charge by short-circuiting the terminals with metal tools: use a densimeter or a voltmeter.
