Personal Safety Precautions
For your own personal safety, please follow the following precautions:
• 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 padicles
(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 toweld a ring (or
the like) to metal, causing a severe
bum.
• 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, wellventilated area.
• Never smoke or allow a spark or flame
inthe vicinity ofthe battery or engine.
Batteries generate explosive gases.
• Neutralize any acid spills thoroughly
with baking soda before attempting to
clean up.

It is important to understand your charger's requirements. This section will tell you
about your charger's electrical requirements and how to prepare a battery for
charging.
PLUGGING IT IN
WARNING: Electrical Shock Hazard.
Be sure that the power cord fits properly
into the outlet. Ifnot, 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 requires a 120V receptacle
installed according to all local codes and
ordinances.
USING AN EXTENSION CORD
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 that the pins on charger's
power cord fit firmly into the extension
cord, and that the extension
cord fits firmly intothe receptacle.
• Checkthat the extension cord is
properly wired and in good electrical
condition.
Make sure that the wire size is large
enough for its length and for the AC
ampere rating as specified in the
chart below.

It is important that you road and follow these guidelines while you are preparing to
charge yourbattery.
Make sure that you have a 12volt or
6 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, ifrequired by the manufacturer,
add distilled water to each cell
untilthe battery acid roaches the
level recommended. This will help
purge excessive gases from the
cells. Be careful notto 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 ofcharge.
• 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.
Ifit is necessary to remove the
battery from the vehicle to charge it,
always remove the grounded
terminal from the battery first. Turn
off allvehicle accessories to avoid
sparks from occurring.
NOTE: A marine battery installed in a
boat must be removed and charged on
shore.
For best results from your battery charger, learn to use it properly. This section will tell
you how to set the controls, how to charge a battery in or out of a vehicle, and how to use
the engine start features.
SE'I-rlNG 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 three switches:
• Use the left switch to match the battery
voltage--either 6 or 12 volt.
• Use the center switch to select a
charge type--MANUAL, AUTOMATIC
DEEP CYCLE, or AUTOMATIC
REGULAR.
• Use the right switch to select a charge
rate--2 AMP charge, 15 AMP charge,
or 125 AMP ENGINE START feature.

Page 7
Charge Type:
• Use the MANUAL setting only ifyou
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.
You must monitor and unplug the
charger when battery is fully charged.
• Use the AUTOMATIC DEEP-CYCLE
setting for all deep-cycle battery
charging. The charger will automatically
stop charging when the battery reaches
full charge and begin charging again
when battery requires.
• Use the AUTOMATIC REGULAR setting
for all but deep-cycle batteries. The
charger will automatically stop charging
when the battery reaches full charge
and begin charging again when battery
requires.
• 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.
AUTOMATIC DEEP CYCLE
AMMETER:
The ammeter indicates the measured
amount of amperes being drawn by the
battery. When you first start charging a
battery, the reading will be high, with
the needle near 15 using the 15 amp
charging rate.
• In the MANUAL setting, as the battery
charges, the needle will fall to about 7
or 8 amps, indicating a charged battery.
In either AUTOMATIC setting, the
needle willfall to zero and the charger
will shut off when the charger's control
circuit senses a full charge. A freshly
charged battery's voltage willdrop
shortly after charging stops, and the
charger, if left connected, may resume
charging. This off-and-on cycling will
continue untilthe battery's voltage no
longer drops enough to restart the
charger.
• At the 2 amp charging rate you will
notice very little needle movement.
When cranking the engine while using
the ENGINE START feature, the needle
will swing into the Start (red) area of the
scale.

Charge Rate:
• Use the 2 AMP charge rate setting for
charging small batteries and warming
large batteries.The lower the charge
rate, the longer itwill take to charge
the battery.
• Use the 15 AMP rate setting for
automotive, deep cycle and other large
batteries.
• Use the 125 AMP ENGINE START
setting only to assist in cranking the
engine.

GREEN, STEADY GLOW:
• In AUTOMATIC, the green LED
indicator will glow steadily and the
meter needle will be at zero when the
charger has completed the charging
cycle.
• In MANUAL mode, YOU MUST monitor
the charging and stop the charging
when the meter indicates about half the
selected rate, 2 or 15 amps.
GREEN, SLOW BLINK:
The charger will be in the MAINTAIN mode
when the LED indicator blinks green
slowly, approximately once per second.
This occurs only in the AUTOMATIC
charging positions after the end of the
AUTOMATIC charging cycle.
RED, STEADY GLOW:
When the red LED indicator glows
steadily, it means that the charger has not
sensed a battery. The leads may be
reversed on the battery posts or one or
both connections may not be making a
solid contact. Check your connections.
RED, SLOW BLINK:
If, after a pre-set number of hours, the
charger fails to fully charge a battery, it
will give up and the red LED indicator will
blink slowly, approximately once per
second, to tell you that something is
wrong with the battery.
CHARGING YOUR BATTERY

Battery Rating Method
Use the following chart to determine the approximate time itwill take to fully charge a
battery that isinitially at 50% State-of-Charge. Identify your battery type and its
associated Charge Time in the table. Common battery types are:
• Small batteries, motomycles, garden tractors, etc., usually rated in Amp-Hours (AH).
• Car and truck batteries, usually rated in Reserve Capacity (RC), Cold Cranking
Amps (CCA), or both.
• Marine, or deep cycle batteries, usually rated in either Amp-Hours or Reserve
Capacity (RC).

Voltmeter Method
To find the time needed to fully charge your battery, determine the battery's charge level
with a Voltmeter or electronic State-of-Charge Tester. Use the table below to convert
Voltmeter and State-of-Charge readings at room temperature to the appropriate Charge
Factor. Then use the formulas that follow the table to determine the approximate Charge
Time.

Charge Time Needed if Amp-Hours is Known
• Find the Charge Factor for your battery in the table on page 11.
• Multiply by the Amp-Hour rating of the battery.
• Divide by the Charger Setting (either 2 Amp or 15 Amp).
• Multiply by 1,25 to get the approximate Hours Needed to bring the battery to full
charge,
Example: 15Amp-Hour (AH) Battery, 50% State-of-Charge,
2 Amp Charger Setting
[(AH x Charge Factor) + Charger Setting] x 1.25 = Hours Needed
(15 x 0.5 - 2) x 1.25 = 4.7 Hours
Charge Time Needed if Reserve Capacity is Known
• Find the Charge Factor for your battery in the table on page 11.
• Multiply by the Reserve Capacity rating ofthe battery.
• Divide by the Charger Setting (either 2 Amp or 15 Amp).
• Multiply by 0.73 to get the approximate Hours Neededto bring the battery to
full charge.
Example: 95-Minute Reserve Capacity (RC) Battery, 25%
State-of-Charge, 15 Amp Charger Setting
[(RC x Charge Factor) ÷ Charger Setting] x 0.73 = Hours Needed
[(95 x 0.75) ÷ 15] x 0.73 = 3.5 Hours
To 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. This will
help prevent accidental damage to
the cords and charger.
