Battery System
Explosive hydrogen gas is given off by charging batteries. Batteries
will explode if an open flame or spark ignites the hydrogen gas.
Never use an open flame in the battery area. Do not strike sparks
near the batteries.
Working on engine starting circuits or alternators with battery
cables connected can cause severe injury or death. Battery cables
should be disconnected from the batteries before working on the
engine starting circuits or the alternator.
If any circuit breaker should trip, do not activate the system until the
cause of the malfunction has been determined and corrected.
The DC electrical system is a 12VDC system and is composed of the following components:
• Batteries
• Battery Charging System
• Circuit Breakers
• Battery Distribution Panel
The batteries are normally charged through an engine-driven alternator or via a shore cord connected to a
battery charger. The number of batteries depends on the number of engines. There is a dedicated battery
for:
• The Port Engine
• The Starboard Engine
There is also a dedicated House battery for running electrical components. Access to the batteries are through an
access port located in the head facility (Figure 3-20).
