Be sure that power cord fits properly into outlet.
If not, have a qualified technician install a proper
outlet. Never alter the AC cord or plug provided.
Improper connection can result in electrical shock.
Your charger should be grounded to reduce the
risk of electrical shock.
Your charger is equipped with an electrical cord that
has an equipment grounding conductor and a grounding plug designed to be used on a 120V circuit. The
plug must be plugged into an outlet that has been
properly installed and grounded in accordance with all
local codes and ordinances.
WARNING
DO NOT exceed 15 Amps on GFCI Outlets. If
using Battery Charger DO NOT exceed 3 Amps.
A 3-Prong Grounded Wall Outlet
This Battery Charger includes GFCI protected outlets.
Proper grounding is required for correct GFCI operation.
5
Page 7
Using the GFCI Outlet
• This charger includes two – GFCI (Ground Fault
Circuit Interrupter) outlets located on its back. The
purpose of a GFCI outlet is to quickly stop the flow of
electricity in the event a ground fault occurs on the
device plugged into the battery charger’s GFCI outlet.
Ground fault circuit interrupters (GFCI) can help
prevent electrical shock or electrocution.
• The GFCI outlets provide auxiliary power to 120V
devices that require less than 15 amps.
The GFCI must be tested before each use. To test:
1. Push the “Reset” button located on the GFCI
receptacle, first to assure normal GFCI operation.
2. Plug a nightlight (with an “ON/OFF” switch) or
other product (such as a lamp) into the GFCI
receptacle and turn the
product “ON.”
3. Push the “Test” button
located on the GFCI receptacle. The nightlight or other
product should go “OFF.”

Using an extension cord
4. Push the “Reset” button, again. The light or other
product should go “ON” again.
NOTE: If the light or other product remains “ON” when
the “Test” button is pushed, the GFCI is not working
properly and should not be used. Call Customer
Service at 1-800-SEARS-64 (1-800-732-7764).
• The power cord must be plugged into a 3-prong
grounded 120V AC wall outlet for the GFCI operation to function. Ground fault circuit interrupters
(GFCI) can help prevent electrical shock or electrocution.
• If you are charging a battery, the GFCI outlet should
be limited to 3 amps of current draw until the charging functions are complete.
• The GFCI outlet should not be used while the
charger is in the ENGINE START mode.
• If using both GFCI outlets at the same time, the
amperage cannot exceed 15 amps of both devices
combined.
The use of an extension cord is not recommended. If
you must use an extension cord, please make sure
that you follow these guidelines:
• Make sure the pins on the plug of the extension cord
are the same number, size, and shape as those of
the plug on the charger.
• Use only 3-conductor (grounded) extension cord
when necessary.
• Check that the extension cord is properly wired and
in good electrical condition.
• Use the recommended minimum AWG (American
Wire Gauge) to be sure that wire size is large
enough for the rating of the charger.
MINIMUM RECOMMENDED EXTENSION CORD
Length of Cord, in Feet 25 50 100 150
AWG* Size of Cord 14 12 10 8
*AWG=American Wire Gauge
Preparing your battery to be charged
It is important that you read and follow these guidelines while you are preparing to charge your battery.
• Make sure that you have a 12 volt or 6 volt lead-acid
battery. Set the volt/amp selector switch to match
the voltage rating of the battery to be charged.
• Clean the battery terminals. Be careful to keep
corrosion from getting in or around your eyes or on
your hands.
• If you have a battery with removable cell caps, if
required, add distilled water to each cell until the
battery acid reaches the level recommended by the
manufacturer. This will help purge excessive gases
from the cells. Be careful not to overfill. If you have a
sealed battery without cell caps, no action is necessary. Continue to the next step listed below.
• Take time to read all battery manufacturer’s specific
precautions, such as removing or not removing
cell caps while charging, and recommended rates
of charge.
• Wear safety glasses. See additional “Personal
Safety Precautions” on page 2.
• Be sure that the area around the battery is well
ventilated while it is being charged. If ventilation is
poor, any gases emitted from the battery can be
manually blown away by using a piece of cardboard
or other non-metallic material as a fan.
• If it is necessary to remove the battery from the
vehicle to charge it, always remove the grounded
terminal from the battery first. A spark may be
caused if all accessories in the vehicle are not
completely turned off.
NOTE: A marine battery installed in a boat must be
removed and charged on shore.

equipment specially designed for marine use.
Charging your battery in the vehicle:
1. Arrange the power cord and charging leads
carefully in order to avoid damage that could be
caused by the hood, door, or moving engine parts.
2. Keep hands, hair, clothing and jewelry clear of the
fan blades, belts, pulleys, and other parts that can
cause injury.
3. Check the polarity of the battery posts using the
identification marks on the battery case: POSITIVE (POS, P, +) and NEGATIVE (NEG, N, -).
4. Identify which battery post is grounded or con-
nected to the chassis. THE NEGATIVE POST IS
NORMALLY THE ONE THAT IS GROUNDED.
5. To charge a negative grounded post system:
Connect the red (POSITIVE) charger clamp to the
ungrounded POSITIVE (POS, P, +) post of the
battery. Next, connect the black (NEGATIVE)
clamp to an unpainted, heavy metal part of the
chassis or engine block, away from the battery. Do
not connect clamp to carburetor, fuel lines, or
sheet metal parts.
To charge a positive grounded post system:
Connect the black (NEGATIVE) charger clamp to
the ungrounded NEGATIVE (NEG, N, -) post of
the battery. Then connect the red (POSITIVE)
clamp to an unpainted, heavy metal part of the
chassis or engine block, away from the battery. Do
not connect clamp to carburetor, fuel lines or
sheet metal parts.
IMPORTANT: Wear safety glasses and face away
from the battery while making connections.
6. Twist or rock clamps back and forth to make a
solid connection. This will help make better
contact and help keep them from slipping off and
causing sparks.
7. Make sure the POWER switch is set to the OFF
position. Next plug the power cord into a 3-prong
grounded 120V AC electrical wall outlet.

on the battery case: POSITIVE (POS, P, +) and
NEGATIVE (NEG, N, -).
NOTE: On top-post batteries, the positive battery
terminal usually has a larger diameter post than the
negative one.
3. Connect the red (POSITIVE) charger clamp to the
POSITIVE post of the battery. Be sure to rock the
clip back and forth to make a solid connection.
4. Attach at least a 6-gauge (AWG) insulated battery
cable of at least 24-inches in length to the
NEGATIVE battery post. This cable will provide a
safer connection because arcing and sparking will
occur away from the battery. (The battery cable is
not provided with the charger, but may be
purchased at most automotive accessory outlets.)
5. Standing as far away from the battery as possible,
connect the black (NEGATIVE) lead of the charger
to the free end of the cable. Rock the clamp to
make a solid connection. IMPORTANT: Wear

Calculating charge times
The Chart Method
Use the following table to more accurately determine
the time it will take to bring a battery to full charge.
First, identify where your battery fits into the chart.
• Small batteries — motorcycles, garden tractors, etc.
— are usually rated in Ampere Hours (AH). For
example: 6, 12, 32 AH etc.
• Batteries in cars and smaller trucks are usually rated
in Reserve Capacity (RC), Cold-Cranking Amps
(CCA), or both.

• Marine, or deep-cycle batteries are usually rated in
Reserve Capacity (RC).
• NR means that the charger setting is NOT RECOM-
MENDED.
Find your battery’s rating on the chart below and note
the charge time given for each charger setting. The
times given are for batteries with a 50-percent charge
prior to recharging. Add more time for severely discharged batteries.

The Hydrometer or Electronic Method
To find the time needed to fully charge your battery,
determine the battery’s charge level with a hydrometer
or electronic Percent-of-Charge Tester. The following
table will help you convert hydrometer readings to
percent of charge values.
SPECIFIC PERCENT PERCENT OF
GRAVITY OF CHARGE CHARGE NEEDED
1.265 100% 0%
1.225 75% 25%
1.155 25% 75%
1.120 0% 100%
When you know the percent of charge and the Amp
Hour (AH) rating of your battery, you can calculate the
approximate time needed to bring your battery to a full
charge.
To convert Reserve Capacity to Amp Hours, divide
Reserve Capacity by 2, and add 16:
Amp Hours = Reserve Capacity + 16
2
NOTE: The Reserve Capacity can be obtained from
the battery specification sheet or the owner’s manual.
To calculate time needed for a charge:
• Find the percent of charge needed. (A battery at 50
percent charge that will be charged to 100 percent
needs another 50 percent (.50).
• Multiply the Amp Hour rating by the charge needed
(.50) and divide by the charger setting (2, 20 or 60
amps).
• Multiply the result by 1.25 and you’ll have the time
needed, in hours, to bring the battery to full charge.
• Add one additional hour for a deep-cycle battery.
Example:
Amp Hour Rating x % of charge needed x 1.25 = hours
Charger Setting of
charge
100 (AH Rating) x .50 (charge needed) x 1.25 = 3.125
20 (Charger Setting) hours
100 x .50 = 2.5 x 1.25 = 3.125
20
You would need to charge your 100-Ampere Hour
Battery for a little more than 3 hours at the 20-Amp
charge rate using the above example.

Your battery charger can be used to jump-start your
car if the battery is low. Follow these instructions when
using the ENGINE START feature.
1. Set the POWER switch to the OFF position. Then
follow the instructions for connecting the charger
to the battery and power source in the section
“Charging a battery in the vehicle.”
2. Set the BATTERY switch to 6V or 12V to match
the battery’s voltage.
3. Set the POWER switch to the ON position. The
METER display will show MAN (manual mode).
4. Touch RESET, MANUAL and ENGINE START
pads in that order. Wait for the display to show
RDY. The charger is now ready to have the engine
cranked.
5. Crank the engine for no more than 5 seconds. If
it does not start, wait 3 minutes. (The display will
show WAIT during this time and RDY when the
time is up.)
6. During extremely cold weather, or if the battery is
severely exhausted, charge the battery for about 5
minutes in 60 amp setting before cranking the
engine.
7. If the engine still does not start, charge the battery
for five more minutes before cranking it again for
five seconds.
8. After the engine starts, unplug the charger power
cord from the wall outlet. Then move the POWER
switch to the OFF position before disconnecting
from the battery.
Important:
Do not try to start the engine without a battery in it.
You could cause damage to the electrical system.
If the engine does turn over, but never starts up, there
is not a problem with the starting system, there is a
problem somewhere else with the vehicle.
STOP cranking the engine until the other problem has
been diagnosed and corrected.
NOTE: The GFCI outlet should not be used while the
Charger is in the Engine Start Mode.
Maintenance and care
A minimal amount of care can keep your battery
charger working properly for years.
1. Clean the clamps each time you are finished
charging. Wipe off any battery fluid that may have
come in contact with the clamps to prevent
corrosion.
2. Coil the input and output cords neatly when storing
the charger. The cords can be wrapped around
the handle of the charger. This will help prevent
accidental damage to the cords and charger.
3. Occasional cleaning of the case with a soft cloth
will keep the finish shiny and help prevent corrosion.
