Help us help you
Remember:
•Place charger as far away from battery being
charged as the charger cables will permit.
•Do not expose charger to rain or snow.
•Never charge a frozen battery. If battery fluid (electro-
lyte) becomes frozen, bring battery into a warm area
to thaw before you begin charging.
•Never allow battery acid to drip on charger when
reading specific gravity or filling battery.
•Never touch the battery clamps together when the
charger is energized.
•Never operate charger if it has received a hard blow,
been dropped, or otherwise damaged. Take it to a
qualified professional for inspection and repair.
•Be sure to position the charger power cord to
prevent it from being stepped on, tripped over, or
damaged.
•Never pull out the plug by the cord when unplug-
ging the charger. Pulling on the cord may cause
damage to the cord or the plug.
•Never set a battery on top of the charger.
•Never place charger directly above battery being
charged. The gases from the battery will corrode
and damage the charger.
•Never use charger for charging dry-cell batteries that
are commonly used with home appliances. These
batteries may burst and cause personal injury.
•Do not operate the charger if it has a damaged
power cord or plug. Have the cord replaced.
Personal Safety Precautions
For your own personal safety, please follow the follow-
ing 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 cloth-
ing. If this happens, wash immediately with soap and
water. Then 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.
•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 ten minutes. Then
immediately get medical attention.

BeforeUsingYourBatteryCharger
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
L! WARNING
Electrical Shock Hazard
Besurethatpowercordfitsproperlyintooutlet. If
not, have a qualified technician install a proper
outlet. Never alter the AC cord or plug provided.
Improperconnectioncanresultinelectricalshock.
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 120 volt circuit. The
plug must be plugged into an outlet that has been
properly installed and grounded in accordance with all
local codes and ordinances.
A TEMPORARY adapter may be used to connect the
charger to a two-pole outlet if a properly grounded outlet
is not available. Use the adapter ONLY until a properly
grounded outlet can be installed by a qualified
electrician.
DANGER: Before using an adapter as illustrated, be
certain that the center screw of the outlet plate is
grounded. The green colored grounding clip of the
adapter must be attached by a screw to a properly
grounded outlet. If unsure whether outlet is properly
grounded, contact aLprofessional electrician. If
necessary, replace the original outlet cover screw with a
longer one that will secure the grounding clip to the
outlet cover and make a ground connection to the
grounded outlet.
Using an extension cord
•
Make sure that the wire size is large enough for its
length and for the AC ampere rating as specified in
the accompanying chart.
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 into the receptacle.
Use only 3-conductor (grounded) extension cord
when necessary.

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 6 or 12 volt lead-acid battery.
• Clean the battery terminals. Be careful to keep
corrosion from getting in or around your eyes.
• 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, gas 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.

Charging Your Battery
Charging a battery in the vehicle:
1. Arrange the power cord and charging leads carefully
to avoid damage that could be caused by the hood,
door, or moving engine parts.
2. Keep clear of fan blades, belts, pulleys, and other
parts that can cause injury.
3. Check the polarity of the battery posts as indicated
on the battery case: POSITIVE (POS, P, or +) and
NEGATIVE (NEG. N or -). NOTE: The positive post
on top-post batteries is usually larger than the
negative post.
4. Identify which battery post is ground or connected 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) battery charger clamp
to the ungrounded POSITIVE (POS, P, +) post of the
battery. Then connect the black (NEGATIVE) clamp
to a heavy, unpainted metal part of the chassis or
engine block, away from the battery. Do not
connect clamp to carburetor, fuel lines, or sheet
metal parts.
NEGATIVE GROUNDED SYSTEM
To charge a positive grounded post system:
Connect the black (NEGATIVE) battery charger
clamp to the NEGATIVE (NEG, N, -) ungrounded
post of the battery. Then connect the red
(POSITIVE) clamp to a heavy, unpainted metal part
of the chassis or engine block. Do not connect
clamp to carburetor, fuel lines, or sheet metal parts.
IMPORTANT: Wear safety glasses and face away
from the battery when making connections.
6. Connect the clamp to the battery post and twist or
rock back and forth to make a solid connection.
This will help keep the clamps from slipping off the
posts and causing sparks.
QUICK DISCONNECT HARNESS
To permanently attach to a small battery (i.e.
motorcycle), connect the red POSITIVE eyelet to the
POSITIVE battery terminal. Then connect the black
NEGATIVE eyelet to the NEGATIVE battery terminal.
Loosen and remove each nut from bolts at battery
terminal. One at a time, slip the eyelets of the harness
wires over the bolt at battery terminal. Replace and
tighen nuts to secure.
7. Select the charge voltage with the Selector Switch
and plug the power cord into a grounded AC
outlet to begin charging.

charged. For this reason it is important to check
charging progress fequently. Overcharging can
damage a battery. You must monitor and unplug
charger when battery is fully charged.
9. When the battery is fully charged, unplug the
charger power cord before attempting to disconnect
charger clamps.
10. Standing away from the battery, remove the
charger clamps in this order: (1) from the chassis
connection and, (2) from the battery post or terminal.
11. Clean and store the battery charger in a dry location.
Charging your battery outside the vehicle:
1. Remove the battery from vehicle, making sure to
disconnect grounded terminal first with all accessories
and lights turned off in the vehicle.
2. Check the polarity of the battery posts as indicated
on the battery case: POSITIVE (POS, P, +) and
NEGATIVE (NEG, N, -).

Calculating charge time
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.
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 rate
(1.5 amps).
Multiply the result by 1.25 and you’ll have the
approximate time needed, in hours, to bring the
battery to full charge.
