3. Remove the battery from the boat to recharge. Do not recharge the battery in the boat.
The service life of your battery depends largely on how it is maintained.
•
Keep batteries dry and clean. Oxidation or dirt on the battery and battery terminals may cause short circuits,
voltage drop, and discharge (especially in damp weather).
•
Clean battery terminals and leads to remove oxidation.
•
Tighten cable terminals tightly.
•
Spray battery terminals and connections with and anti-corrosive agent, or coat them with petroleum jelly.
•
Check that all other electrical connections are dry and free of oxidation, and that there are not loose connec-
tions.
•
Always switch off the charging circuit before removing the battery charger connectors.
•
Inspect your battery at regular intervals for specific gravity (state of charge), individual cell water level, cleanli-
ness and tight, greased connections.
•
If the battery has become discharged for no apparent reason, check all electrical system components for
malfunction, or a switch left
ON, before installing a recharged battery.
•
Electrolyte levels should be 0.2 – 0.4 inches (5 – 10 mm) over the plates in the battery. Top off if necessary,
using distilled water. After topping off, run the engine at fast idle for at least 30 minutes to charge the battery.
Note: Some maintenance-free batteries have special instructions. Make sure to follow them carefully.
Battery electrolyte is a corrosive acid and should be handled with care. If you spill or splash electrolyte on any
part of the body, immediately flush the exposed area with liberal amounts of water and seek medical attention
as soon as possible.
Note: It is important that the battery connections are correct. The negative battery cable must be attached to the
negative terminal (–) on the battery and the engine’s positive cable must be attached to the positive terminal (+) on the
battery.
Failure to follow the safety precautions below may result in electrical sparks igniting fuel vapors, and thereby
causing fire or explosion.
1. Operate boat’s bilge blower for at least 5 minutes. Open engine cover or hatch and check the boat’s bilge
area for gasoline fumes. If any fumes can be detected by smell, do not operate the boat until the source
can be found, the spill cleaned up, and the cause corrected.
2. Do not connect cables to battery until all other electrical connections have been made.
3. Make sure the ignition switch is
OFF before removing or installing electrical equipment, checking any
electrical connections, or installing battery cables.
See your Volvo Penta
dealer for recommendations on installing multiple batteries.
Note:
When replacing your battery, read and understand the information supplied with it before you begin installation.
