PREPARING YOUR BATTERY TO BE CHARGED
It is important that you read and follow these guidelines while you are preparing to
charge your battery.
such as removing or not removing
cell caps while charging, and
recommended rates of charge.
•
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.
•
•
•
Wear safety glasses. See additional
"Personal Safety Precautions" on
page 4.
•
•
Clean the battery terminals. Be
careful to keep corrosion from
getting in or around your eyes.
Be sure that the area around the
battery is well ventilated while it is
being charged.
For batteries with removable cell
caps, if required by the manufac-
turer, 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.
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.
Continue to the next step listed below.
NOTE: A marine battery installed in a
boat must be removed and charged on
shore.
•
Take time to read all battery
manufacturer’s specific precautions,
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
•
•
The center switch controls the type of
charge you want — AUTOMATIC,
MANUAL, or MAINTAINER.
All controls are located on the front of
the charger. Follow these instructions
to obtain the correct charge level for
your battery.
The switch on the lower right selects
the charge rate:
SELECTOR SWITCHES:
• 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.
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.

seasonal farm equipment and the like.
Use after fully charging the
battery in one of the charging
positions.
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.
MANUAL
L
AUTOMATIC
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.
DEEP CYCLE
L
REGULAR
GEL CELL
Battery Voltage:
•
•
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.
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.
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.

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.
2 AMP

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.
•
•
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.
•
In the MANUAL setting, as the battery
charges, the needle will fall to about 8
or 10 amps, indicating a charged
battery.
Use the MAINTAINER to maintain a
charge in batteries stored for long
periods, such as those in RVs,
•
In both AUTOMATIC settings, the meter
needle will fall to zero when the battery
has completed the charging cycle. A
7
freshly charged battery’s voltage will
drop shortly after charging stops, and
the charger, if left connected, may
resume charging. This off-and-on
cycling will continue until the battery’s
voltage no longer drops enough to
restart the charger.
CHARGING YOUR BATTERY
Chargingyourbatteryinsidethe
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.
•
At the 2 amp charging rate you will
notice very little needle movement.
2. Keep 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, -). NOTE:
The positive post on top-post batteries
is usually larger than the negative post.
4. Identify which battery post is the
ground or connected to the chassis.
THE NEGATIVE POST IS
NORMALLY THE ONE THAT IS
GROUNDED.
LED INDICATORS:
Two LED INDICATORS provide
information on the state-of-charge by
glowing steadily or blinking at different
intervals.
5. To charge a negative grounded
post system: Connect the red
(POSITIVE) charger clamp to the
ungrounded POSITIVE (POS, P, +)

fuel lines or sheet metal parts.
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.
IMPORTANT: Wear safety glasses
and turn face away from the battery
when making connections.
RED, SLOW BLINK:
The charger has sensed a battery
condition which prevents further charging.
Have the battery checked by a Sears
technician.
