NOTE! Some maintenance-free batteries have special
instructions. Make sure to follow them carefully.
WARNING!
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 posi-
tive terminal (+) on the battery.
DANGER!
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 elec-
trical connections have been made.
3. Make sure the ignition switch is OFF before remov-
ing or installing electrical equipment, checking any
electrical connections, or installing battery cables.
See your Volvo Penta dealer for recommendations on install-
ing multiple batteries.
NOTE! When replacing your battery, read and under-
stand the information supplied with it before you begin
installation.
1. Batteries must be heavy-duty and constructed for ma-
rine use. They can be either vented/refillable,
maintenance-free, or deep-cycle with a CCA or MICA
rating. Refer to Specifications pages for the correct bat-
tery sizes.
2. Use bolts and nuts to secure battery cables to the bat-
tery terminals. Do not use wing nuts to secure battery
cables, even if they were supplied with the battery.
3. Loose battery connections can cause damage to the
engine's electrical system.
4. Service electrical components only while the motor is not
running. Be careful when identifying positive and negative
battery cables and terminals. If you touch the wrong termi-
nal with a battery cable, even briefly, the motor's charging
system could be damaged.

WARNING!
The battery terminal connections must always be
insulated. If the battery mounting system does not
cover the connections, install protective covers. This
will help prevent shorting or arcing at the battery
terminals.
DANGER!
Fumes vented during battery charging may cause an
explosion.
Do not expose battery to electrical sparks or an open
flame.
Do not use jumper cables and a booster battery to
start engine.
If the battery compartment is not properly venti-
lated, remove battery from boat to recharge.
If the battery has become discharged ("dead") for no appar-
ent reason, check all electrical system components for mal-
function, or for a switch left in the ON position, before install-
ing a recharged battery.
DANGER!
Failure to follow the safety precautions below may
result in electrical sparks igniting fuel vapors causing
fire or explosion.
Operate the boat's bilge blower for at least 5 min-
utes. Open the 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 you find the source, clean up the spill, and
correct the cause.
Do not connect cables to battery until all other elec-
trical connections have been made.
Make sure the ignition switch is OFF before remov-
ing or installing electrical equipment, checking any
electrical connections, or installing battery cables.
