DC INSTALLATION (12 V)

7.2.1 Battery use and distribution

General points
On board electrical power is direct current.
The boat's electrical system comprises service batteries and the engine battery or batteries.
The service batteries serve as the power supply for all the boat's electrical components. The
engine battery is used solely to power the engine's starter motor.
the batteries are charged either by a load distributor or:
- by the alternator linked to the engine when the engine is running,
- by the battery charger (if the boat has one).
It is imperative that when the boat is first launched, a professional engineer connects the
batteries.
Always check the condition of the batteries and charge system before putting to sea.
The battery banks are isolated from one another by a charge divider (see below).

Maintenance
- Avoid charging batteries to a voltage greater than 14,6 V.
- Keep the batteries clean and dry.
- Regularly check that the terminals and connection cables are clean. If necessary, apply a
thin coating of paraffin on the terminals, to prevent corrosion.
- Regularly recharge all of the batteries onboard.
- Continuously maintain the charged batteries: this determines their length of life.
- Avoid long periods of electrical inactivity ( for example when wintering the boat).
