Help us help you  
Remember:  
Place charger as far away from battery being  
charged as the charger cables will permit.  
Never touch the battery clamps together when the  
charger is energized.  
Do not expose charger to rain or snow.  
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 charge a frozen battery. If battery fluid (elec-  
trolyte) 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 pull out the plug by the cord when unplugging  
the charger. Pulling on the cord may cause damage  
to the cord or the plug.  
Do not operate the charger if it has a damaged  
power cord or plug. Have the cord replaced.  
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.  
Personal Safety Precautions  
For your own personal safety, please follow the  
following precautions:  
Wear complete eye and clothing protection when  
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.  
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.  
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 10 minutes. Then  
immediately get medical attention.

Before Using Your Battery Charger  
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  
Be sure that power cord fits properly into outlet.  
If not, 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 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 ground-  
ing 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 a professional electrician. If neces-  
sary, 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.  
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 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 guide-  
lines while you are preparing to charge your battery.  
• Make sure that you have a 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 neces-  
sary. 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.

Using Your Battery Charger  
For best results from your battery charger, learn to use it properly. This section tells how to set the controls and how  
to charge a battery in or out of the vehicle.  
Setting the Controls  
SELECTOR SWITCHES:  
A 3-way switch is used to select the 2-AMP or the  
10-AMP charge rate or the ENGINE START feature.  
AMMETER:  
L
10 AMP  
L
2 AMP  
L
ENGINE  
START  
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 10 using the 10 amp charging rate.  
As the battery charges, the needle will fall to about  
4 or 5 amps, indicating a charged battery.  
At the 2 amp charging rate you will see little needle  
movement.  
When using the ENGINE START feature, the needle will  
swing into the Start (red) area of the scale while cranking  
the engine.  
START  
The percent of charge scale is intended as a visual aid to  
help simplify reading the state of charge of the battery.  
The meter is scaled for use with the 10 amp charge rate  
only. For the 2 amp charge rate use the red triangle. The  
percent of charge is based on current drawn by the  
battery. For this reason accuracy will vary with the size  
and battery type.  
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  
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 while making connections.  
To charge a positive grounded post system:  
Connect the black (NEGATIVE) battery charger  
clamp to the NEGATIVE (NEG, N, -) ungrounded

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.  
7. Select the charge rate with the Selector Switch then  
plug the power cord into a grounded AC outlet to  
begin charging.  
8. The charger will not stop when the battery is fully  
charged. For this reason it is important to check  
charging progress frequently. Overcharging can  
damage a battery, you must monitor and unplug  
charger when battery is fully charged.  
9. When the battery is fully charged, the AMMETER  
pointer will fall to about half the charge rate  
selected. For specific positions, refer to the  
“Ammeter” section in “Using your battery charger”  
on a page 6.  
10. When the battery is fully charged, unplug the  
charger power cord before attempting to disconnect  
charger clamps.  
11. 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.  
12. Clean and store the battery charger in a dry location.  
Charging your battery outside the vehicle:

3. Connect the red (POSITIVE) charger clamp to the  
POSITIVE post of the battery. Be sure to rock the  
clip back and forth to make a solid connection.  
4. Attach a 6-gauge (AWG) or a 4-gauge (SAE)  
insulated battery cable of at least 24-inches in  
length to the NEGATIVE battery post. This cable  
will provide a safer connection because arcing and  
sparking will occur away from the battery. (The  
battery cable is not provided with the charger, but  
may be purchased at most automotive accessory  
outlets.)  
5. Take the other end of the 6-gauge (AWG) or a  
4-gauge (SAE) insulated 24-inch cable and,  
standing as far away from the battery as possible,  
connect the black (NEGATIVE) lead of the charger  
to the free end of the cable. Rock the clamp to  
make a solid connection.

Calculating charge time  
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.  
Marine, or deep-cycle batteries are usually rated in  
Reserve Capacity (RC).  
NR means that the charger setting is NOT  
RECOMMENED.  
Small batteries — motorcycles, garden tractors, etc.  
— are usually rated in Ampere Hours (AH). For  
example; 6 to 12 AH, or 12 to 32 AH.  
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 prior to recharging. Add more time for se-  
verely discharged batteries.  
Batteries in cars and smaller trucks are usually  
rated in Reserve Capacity (RC), Cold-Cranking  
Amps (CCA), or both.

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 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.

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:  
You would need to charge your 100-Ampere Hour Bat-  
tery for approximately 6¼ hours at the 10-Amp charge  
rate using the above example.

Using the engine start feature  
Your battery charger can be used to jump start your  
car if the battery is low. Follow these instructions on  
how to use the ENGINE START feature.  
1. Connect the charger to the battery. (Follow con-  
necting instructions given in "Charging Your  
Battery" on page 6.)  
2. Set the Selector Switch on ENGINE START.  
3. Crank the engine for no more than 7 seconds.  
If it does not start, wait at least 4 minutes before  
cranking again. In extreme cold or if the battery is  
severely discharged, charge the battery for about 5  
minutes in the 10 amp postion, before cranking the  
engine.  
4. After the engine starts, unplug the charger power  
cord from the AC outlet. Then disconnect the  
charger from the battery.  
IMPORTANT: Do not try to start the engine without a  
battery in it. You could cause damage 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 in the engine. STOP crank-  
ing the engine until the other problem has been  
identified and corrected.  
Maintenance and care  
A minimal amount of care can 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.  
3. Occasional cleaning of the case of the charger  
with a soft cloth will keep the finish shiny and help  
prevent corrosion.
