6.4.1 Checking and maintaining batteries

Component Maintenance Notes and precautions
Batteries Battery check (accumulators) The batteries installed are low maintenance batteries, with no special control needs: It is recommended, however, to check the status at least twice a year and whenever there is a difficulty or delaying of charging time.
CAUTION

In case of contact with battery acid, wash the contaminated part with fresh water for at least 15 minutes and consult a doctor.

CAUTION

Remove bracelets, rings and every other piece of jewellery before working on the batteries.

WARNING

All maintenance operations listed must be performed only by skilled personnel.

CAUTION

Monitor the voltage of the engine and service batteries. During the charging phase 29.1V can be reached, this is a temporary value, well tolerated, both by the batteries and by the battery charger. This value must be monitored and, if this situation lasts for too long, the magneto-thermal breakers of the battery charger must be disconnected.

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 the charge status each week.

WARNING

The battery replacement must always use the original model of battery originally furnished by the shipyard.

Carry out following checks:
Terminal inspection
