Without an engine running, however, the 12-volt equipment will eventu-
ally drain the batteries they are using. If this occurs, either start the
engines or use the onboard battery chargers to recharge the batteries.
Never allow the boat’s batteries to become completely discharged.
Completely discharging a battery can damage it to the point that it can no
longer be recharged. The battery chargers should always be operating
when your boat is connected to shore power. If you leave your boat for
an extended period of time and the boat is not connected to shore
power, turn all battery master disconnect switches to the “OFF” position.
Your boat is equipped with three battery chargers, one of which is a
combined inverter and battery charger.
2.1.6.1 Main Battery Charger
If your boat has Volvo D12 engines, the main battery charger monitors
and maintains the voltage levels of the generator battery only. If your
boat does not have Volvo D12 engines, the main battery charger moni-
tors and maintains the voltage levels of the engine batteries and the
generator battery. Additionally, when the generator is operating, its
alternator maintains the voltage level of the generator battery.
To operate the battery charger:
1. Provide AC power to the boat, from either a shore power source or
the onboard generator. Refer to 3.2.1 Shore Power or 3.2.2 Gen-
erator Power for more information.
2. On the AC Control Center, switch the Main Battery Charger circuit
breaker “ON.” Refer to 3.3.2 AC Control Center for more informa-
tion on this circuit breaker. The main battery charger now automati-
cally charges the associated battery(ies) when its voltage drops
below a predetermined level.
The main battery charger is located in the engine room on the port aft
bulkhead. Refer to 9.7.4 Engine Room for the exact location of this
battery charger.
2.1.6.2 Bow Thruster Battery Charger
If your boat has Volvo D12 engines, the bow thruster battery charger
monitors and maintains the voltage levels of the propulsion engine/
thruster batteries. If your boat does not have Volvo D12 engines, the bow
thruster battery charger monitors and maintains the voltage levels of the
dedicated thruster batteries only.
