PERSONAL SAFETY PRECAUTIONS
For your own personal safety, please follow the following precautions:
SAFETYOPERATIONMAINTENANCETROUBLESHOOTINGPARTS
• Wear complete eye and clothing
protection when working with lead-
acid batteries.
• Be sure that someone is within range
of your voice to come to your aid if
needed while you work with or are near
a lead-acid battery.
• Have plenty of fresh water and soap
nearby for use in case battery acid
contacts your eyes, skin, or clothing. If
this happens, wash immediately with
soap and water. Then get medical
attention.
• Avoid touching your eyes while
working with a battery. Acid particles
(corrosion) may get into your eyes. If
this occurs, flush eyes immediately
with running cold water for at least 10
minutes. Then immediately get medical
attention.
• Remove all personal metal items
from your body, such as rings,
bracelets, necklaces, and watches
while working with a lead-acid battery.
A battery can produce a short circuit
current high enough to weld a ring
(or the like) to metal, causing a severe
burn.
• Take care not to drop any metal tool or
metal object onto the battery. This may
spark or short circuit the battery or
another electrical device that may
cause an explosion.
• Always operate your battery charger in
an open, well ventilated area.
• Never smoke or allow a spark or
flame in the vicinity of the battery or
engine. Batteries generate explosive
gases.
• Neutralize any acid spills thoroughly
with baking soda before attempting to
clean up.

PREPARING YOUR BATTERY TO BE CHARGED
SAFETYOPERATIONMAINTENANCETROUBLESHOOTINGPARTS
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
24 volt lead-acid battery. Set the
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.
• For batteries with removable cell
caps, if required by the manufacturer, add distilled water to each cell
until the battery acid reaches the
level recommended. 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 4.
• Be sure that the area around the
battery is well ventilated while it is
being charged.
• If it is necessary to remove the
battery from the vehicle to charge it,
always remove the grounded
terminal from the battery first. Turn
off all vehicle accessories to avoid
sparks from occurring.
NOTE: A marine battery installed in a
boat must be removed and charged on
shore.
USING YOUR BATTERY CHARGER
To obtain the best results from your battery charger, you must know how to use it
properly. This section will tell you how to set the controls, and how you can charge a
battery while it is still in the vehicle, or you can remove it and then charge it. Follow
the instructions below depending on how you choose to charge your battery.
SETTING THE CONTROLS
All controls are located on the front of
the charger. Follow these instructions
to obtain the correct charge level for
your battery.
SELECTOR SWITCHES:
Your charger has four switches:
• The switch on the top right is used to
select the type of battery being
charged — REGULAR, DEEP
CYCLE, or GEL CELL.
• The switch on the left is used to select
the battery voltage— either 12 or 24
volt.
• The center switch controls the type of
charge you want — AUTOMATIC,
MANUAL, or MAINTAINER.
• The switch on the lower right selects
the charge rate:
• 2 AMP charge for 12 VOLT
batteries/24 VOLT systems.
• 10 AMP charge for 12 VOLT
batteries/ 24 VOLT systems.
• 20 AMP for 12 VOLT batteries or
15 AMP for 24 VOLT systems. The
battery voltage selection (12 or 24
volt) will automatically determine
whether the 20 or the 15 amp
charge rate is used.
6
Page 7
Battery Type:
The charger is designed to provide a
specific charge best suited for charging
each type of battery. Charging a GEL
CELL battery as a REGULAR or DEEP
CYCLE battery can permanently
damage it. Charging a battery on
anything but the proper selection can
result in a partial charge or damaged
battery. DO NOT charge a Gel Cell on
any other setting but, Gel Cell.

GEL CELLREGULAR
Battery Voltage:
Select the voltage of your battery. The
most common applications will be 12 volt,
but 24 volt battery systems are being
widely used in special applications.
12 VOLT
24 VOLT
Charge Type:
• Use the MANUAL setting only if you
check the charging progress
frequently. The charger will not stop
charging when the battery reaches
full charge, possibly damaging the
battery if left on too long. A
severely
discharged battery may not have
enough charge to start the control
circuit in an automatic setting. In this
case, charge on MANUAL until the
battery has enough charge to accept
an Automatic setting.
• Use the AUTOMATIC setting for all
batteries and charge rates. The
charger will automatically stop
charging when the battery reaches full
charge and begin charging again when
battery requires.
• Use the MAINTAINER to maintain a
charge in batteries stored for long
periods, such as those in RVs,
seasonal farm equipment and the like.
Use after fully charging the
battery in one of the charging
positions.
AUTOMATIC
MANUAL
L
MAINTAINER
Charge Rate:
• Use the 2 AMP charge rate when you
can afford the time. The lower the
charge rate, the longer it will take, but
the battery is subjected to much less
stress. Unless a Gel Cell battery
manufacturer recommends otherwise,
use the 2 AMP rate for charging.
• Use the10 AMP 12/24 VOLT rate for
most common charging applications.
It provides the most complete charge
with the least stress on the battery.
• Use the 20 AMP 12 VOLT rate when
speed is important. This rate is
selected when 12 VOLT is selected on
the Battery Voltage switch. It provides
a faster charge than the 10 AMP rate.
The 15 AMP 24 VOLT rate is selected
when 24 VOLT is selected on the
Battery Voltage switch.
10 AMP 12/24 VOLT

AMMETER:
The ammeter indicates the measure
amount of amperes being drawn by the
battery. When you first start charging a
battery, the reading will be high, with
the needle near 20 using the 20 amp
charging rate.
• In the MANUAL setting, as the battery
charges, the needle will fall to about 8
or 10 amps, indicating a charged
battery.
• In both AUTOMATIC settings, the meter
needle will fall to zero when the battery
has completed the charging cycle. A

resume charging. This off-and-on
cycling will continue until the battery’s
voltage no longer drops enough to
restart the charger.
• At the 2 amp charging rate you will
notice very little needle movement.
LED INDICATORS:
Two LED INDICATORS provide
information on the state-of-charge by
glowing steadily or blinking at different
intervals.
GREEN, FAST BLINK:
When the charger is charging a battery,
the green LED indicator will blink rapidly.
GREEN, STEADY GLOW:
In all settings, the green LED indicator
will glow when the charging cycle is
complete. In the MANUAL setting, stop
charging when the green LED indicator
glows steadily.
GREEN, SLOW BLINK:
A slowly blinking green LED indicates that
the charger is maintaining the battery’s
state of charge in the MAINTAINER mode.
RED, STEADY GLOW:
When the red LED indicator glows
steadily, it means that the charger has not
sensed a battery voltage. The leads may
be reversed on the posts, or one or both
connections may not be making solid
contact. Check your connections.
RED, SLOW BLINK:
The charger has sensed a battery
condition which prevents further charging.
Have the battery checked by a Sears
technician.
CHARGING YOUR BATTERY
Charging your battery inside 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.
