board requires equipment specially
designed for marine use.
8. GROUNDING AND AC POWER CORD CONNECTIONS
This battery charger is for use on a nominal
120 volt circuit and has a grounded plug.
The charger must be grounded, to reduce
the risk of electric shock. The plug must
be plugged into an outlet that is properly
installed and grounded in accordance with
all local codes and ordinances. The plug
pins must t the receptacle (outlet). Do not
use with an ungrounded system.
DANGER: Never alter the AC cord or
plug provided – if it does not t the outlet,
have a proper grounded outlet installed
by a qualied electrician. An improper
connection can result in a risk of an
electric shock or electrocution.
NOTE: Pursuant to Canadian
Regulations, use of an adapter plug
is not allowed in Canada. Use of an
adapter plug in the United States is not
recommended and should not be used.
USING AN EXTENSION CORD
The use of an extension cord is not
recommended. If you must use an
extension cord, follow these guidelines:
•Pins on plug of extension cord must be
the same number, size, and shape as
those of plug on charger.
•Ensure that the extension cord is
properly wired and in good electrical
condition.
•Wire size must be large enough for
the AC ampere rating of charger, as
specied:
Length of cord (feet) 25 50 100 150

LED INDICATORS
CLAMPS REVERSED (red) LED
ashing:The connections are reversed.
CHARGING (yellow/orange) LED lit:
The charger is charging the battery.
CHARGING (yellow/orange) LED
ashing: The charger is in abort mode.
CHARGED/MAINTAINING (green) LED
pulsing: The battery is fully charged and
the charger is in maintain mode.
NOTE: See the Operating Instructions
section for a complete description of the
charger modes.
BATTERY TYPE BUTTON
Use this button to select the type of battery.
•STANDARD – Used in cars, trucks and
motorcycles, these batteries have vent caps
and are often marked “low maintenance” or
“maintenance-free”. This type of battery is
designed to deliver quick bursts of energy
(such as starting engines) and has a
greater plate count. The plates are thinner
and have somewhat different material
composition. Standard batteries should not
be used for deep-cycle applications.
•AGM – The Absorbed Glass Mat
construction allows the electrolyte to
be suspended in close proximity with
the plate’s active material. In theory,
this enhances both the discharge and
recharge efciency. The AGM batteries
are a variant of Sealed VRLA (valve
regulated lead-acid) batteries. Popular
uses include high-performance engine
starting, power sports, deep-cycle, solar
and storage batteries.
•GEL – The electrolyte in a GEL cell has
a silica additive that causes it to set up or
stiffen. The recharge voltages on this type of
cell are lower than those for other styles of
lead-acid battery. This is probably the most
sensitive cell in terms of adverse reactions
to overvoltage charging. Gel batteries are
best used in VERY DEEP cycle application
and may last a bit longer in hot weather
applications. If the wrong battery charger is
used on a gel cell battery, poor performance
and premature failure will result.
11. OPERATING INSTRUCTIONS

set the ON/OFF switch to the Engine
Start position. The Engine Start LED
will illuminate.
5. Crank the engine until it starts or 5
seconds pass. If the engine does not
start, wait 3 minutes before cranking
again. This allows the charger and
battery to cool down.
NOTE: During extremely cold weather, or if
the battery is under 2 volts, boost the battery
for 5 minutes before cranking the engine.
6. If the engine fails to start, use the
50A Boost rate for 5 minutes before
attempting to crank the engine again.
7. After the engine starts, move the switch
to the OFF position and unplug the AC
power cord before disconnecting the
battery clips from the vehicle.
8. Clean and store the charger in a dry
location.
NOTE: If the engine does turn over but

cranking the engine until the other problem
has been diagnosed and corrected.
AUTOMATIC CHARGING MODE
When an Automatic Charge is performed,
the charger switches to the maintain mode
automatically after the battery is charged.
ABORTED CHARGE
If charging cannot be completed normally,
charging will abort. When charging
aborts, the charger’s output is shut off,
the CHARGING (yellow/orange) LED will
ash, and the display will show an error
code. To reset after an aborted charge,
unplug the charger from the AC outlet,
wait a few moments and plug it back in.
DESULFATION MODE
Desulfation could take 8 to 10 hours. If
desulfation fails, charging will abort, the
CHARGING (yellow/orange) LED will
ash, and the display will show F02.
COMPLETION OF CHARGE
Charge completion is indicated by the
CHARGED/MAINTAINING (green) LED.
When pulsing, the charger has switched to
the maintain mode of operation.
MAINTAIN MODE
(FLOAT-MODE MONITORING)
When the CHARGED/MAINTAINING
(green) LED is pulsing, the charger has
started maintain mode. In this mode, the
charger keeps the battery fully charged
by delivering a small current when
necessary. If the charger has to provide
its maximum maintain current for a
continuous 12 hour period, it will go into
abort mode (see Aborted Charge section).
This is usually caused by a drain on the
battery or the battery could be bad. Make
sure there are no loads on the battery. If
there are, remove them. If there are none,
have the battery checked or replaced.

12. MAINTENANCE AND CARE
A minimal amount of care can keep your
battery charger working properly for years.
•Clean the clamps each time you are
nished charging. Wipe off any battery
uid that may have come in contact with
the clamps to prevent corrosion.
•Occasionally cleaning the case of the
charger with a soft cloth will keep the
nish shiny and help prevent corrosion.
•Coil the input and output cords neatly
when storing the charger. This will help
prevent accidental damage to the cords
and charger.
•Store the charger unplugged from the AC
power outlet in an upright position.
•Store inside, in a cool, dry place. Store
the clamps on their support posts, to
ensure they do not come into contact
with any metallic surface.

on when properly
connected.
AC outlet is dead.
Poor electrical connection.
Battery is defective.
Check for open fuse or circuit
breaker supplying AC outlet.
Check power cord and extension
cord for loose tting plug.
Have the battery checked.
Three LEDs come on for
2 seconds, then turn off.
The charger is plugged into an
AC outlet.
No problem; this is normal.
Engine start does
not work.
Drawing more than 250 amps.
Failure to wait 3 minutes (180
seconds) between cranks.
The charger may be
overheated.
Battery may be severely
discharged.
Crank time varies with the
amount of current drawn. If
cranking draws more than 250
amps, crank time may be less
than 5 seconds.
When the Engine Start LED
blinks, wait 3 minutes of rest time
before the next crank.
The thermal protector may have
tripped and needs a little longer
to reset. Make sure the charger
vents are not blocked. Wait and
try again.
On a severely discharged battery,
use the 40A Boost rate for 10 to 15
minutes, to help assist in cranking.
The Boost LED is
ashing.
The charger was left in Boost
mode for an extended period
of time.
The Boost LED will ash for 30
minutes, then go off, and the
Charging LED will light, indicating
the charger has switched to
Charging mode.
14. BEFORE RETURNING FOR REPAIRS
•When a charging problem arises, make
certain that the battery is capable of
accepting a normal charge. Double check
all connections, the AC outlet for a full
120 volts, the charger clamps for correct
polarity and the quality of the connections
from the cables to the clamps and from
the clamps to the battery system. The
clamps must be clean.
•When an UNKNOWN OPERATING
PROBLEM arises, please read the
complete manual and call the customer
service number for information. This will
usually eliminate the need for return.
