BATTERY ChARGING - AC CONNECTIONS
8.1
For all grounded cord-connected battery chargers:
• GROUNDING AND AC POWER CORD CONNECTION
INSTRUCTIONS – Charger should be grounded to reduce risk of electric
shock. Charger is equipped with an electric cord having an equipment-
grounding conductor and a grounding plug. The plug must be plugged
into an outlet that is properly installed and grounded in accordance with
all local codes and ordinances.
dANGER – Never alter AC cord or plug provided – if it will not fit outlet,
have proper outlet installed by a qualified electrician. Improper connec-
tion can result in a risk of an electric shock.
8.2
For grounded, cord-connected battery chargers with an input rating
less than 15 amperes and intended for use on a nominal 120-volt
circuit:
• This battery charger is for use on a nominal 120-volt circuit, and has a
grounding plug that looks like the plug illustrated in sketch A in Figure
8.4. A temporary adapter, which looks like the adapter illustrated in
sketches B and C, may be used to connect this plug to a two-pole recep-
tacle as shown in sketch B if a properly grounded outlet is not available.
The temporary adapter should be used only until a properly grounded
outlet can be installed by a qualified electrician.
dANGER – Before using adapter as illustrated, be certain that center
screw of outlet plate is grounded. The green-colored rigid ear or lug ex
tending from adapter must be connected to a properly grounded outlet–
make certain it is grounded. If necessary, replace original outlet cover
plate screw with a longer screw that will secure adapter ear or lug to
outlet cover plate and make ground connection to grounded outlet.

12. 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:
12.1 Push the “Reset” button located on the GFCI receptacle, first to assure
normal GFCI operation.
12.2 Plug a night light (with an “ON/OFF” switch) or other product (such as a
lamp) into the GFCI receptacle and turn the product “ON.”
12.3 Push the “Test” button located on the GFCI receptacle. The night light or
other product should go “OFF.”
12.4 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).
12.5 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.
12.6 If you are charging a battery, the GFCI outlet should be limited to 3 amps
of current draw until the charging functions are complete.
12.7 The GFCI outlet should not be used while the charger is in the ENGINE
START mode.
12.8 If using both GFCI outlets at the same time, the amperage cannot exceed
15 amps of both devices combined.

14. CALCULATING ChARGE TIME
14.1 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 to 12 AH, or 12 to 32 AH.
• 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 RECOMMENdEd.
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 rate prior to recharging. Add more time for severely
discharged batteries.

14.2 The hydrometer or Electronic Method
To find the time needed to fully charge your battery, determine the bat-
tery’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.
PERCENT OF ChARGE

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 specifica-
tion 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
• 15 •
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 or 10 amps).
• Multiply the result by 1.25 and you’ll have the approximate 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 charge needed

You will need to charge your 100-Ampere Hour Battery for approximately
1 1/2 hours at the 50-Amp charge rate using the above example.
15. USING ThE ENGINE START FEATURE
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.
15.1 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.”
15.2 Set the BATTERY switch to 6V or 12V to match the battery’s voltage.
15.3 Set the POWER switch to the ON position. The METER display will show
MAN (manual mode).
15.4 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.
15.5 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.)
15.6 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.
15.7 If the engine still does not start, charge the battery for five more minutes
before cranking it again for five seconds.
15.8 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.
• 16 •
Important:
Do not try to start the engine without a battery in it. You could cause dam-
age 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.
16. MAINTENANCE INSTRUCTIONS
