Important Safety Instructions  
– SAVE THESE INSTRUCTIONS –  
To reduce the risk of explosion, explosive gases, or injury while  
using your battery charger, follow the precautions listed below:  
WARNING  
• Read all instructions and cautions printed on the  
battery charger, battery, and vehicle or equipment  
using battery.  
Do not disassemble charger. Take it to a  
qualified service professional if service or repair  
is required. Incorrect assembly may result in fire  
or electrical shock.  
• Use charger only on lead-acid type rechargeable  
batteries, such as those used in cars, trucks,  
tractors, airplanes, vans, RV’s, trolling motors, etc.  
This charger is not intended to supply power to a  
low voltage electrical system other than in an  
automotive application.  
• To reduce risk of electrical shock, unplug the  
charger from the outlet before attempting any  
maintenance or cleaning.  
Always charge battery in a well ventilated area.  
Use only attachments recommended or sold by  
manufacturer. The use of attachments not recom-  
mended by the manufacturer may result in fire,  
electric shock, or injury.  
Wear complete eye and clothing protection when  
working with lead-acid batteries.  
Help us help you  
Remember:  
Place charger as far away from battery being  
charged as the charger cables will permit.  
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.  
Do not expose charger to rain or snow.  
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.  
Never charge a frozen battery. If battery fluid  
(electrolyte) 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.  
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.  
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.  
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.  
Never use charger for charging dry-cell batteries  
that are commonly used with home appliances.  
These batteries may burst and cause personal  
injury.  
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.  
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.  
Always operate your battery charger in an open,  
well ventilated area.  
Be sure to position the charger power cord to  
prevent it from being stepped on, tripped over, or  
damaged.  
Never smoke or allow a spark or flame in the vicinity  
of the battery or engine. Batteries generate explo-  
sive gases.  
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.  
Neutralize any acid spills thoroughly with baking  
soda before attempting to clean up.  
• WARNING: Handling the cord on this product or  
cords associated with accessories sold with this  
product, will expose you to lead, a chemical known  
to the State of California to cause cancer and birth  
defects or other reproductive harm. Wash hands  
after handling.  
Do not operate the charger if it has a damaged  
power cord or plug. Have the cord replaced.

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.  
WARNING: Improper adapter con-  
nection can result in electrical shock.  
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 metal screw to a properly grounded  
outlet. If unsure whether outlet is properly grounded,  
contact a professional 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  
The use of an extension cord is not recommended. If  
you must use an extension cord, please make sure  
that you follow these guidelines:  
MINIMUM RECOMMENDED EXTENSION CORD  
Length of Cord, in Feet  
25  
50  
100 150  
• Make sure the pins on the plug of the extension cord  
are the same number, size, and shape as those of  
the plug on the charger.  
AWG* Size of Cord  
16  
12  
10  
8
*AWG=American Wire Gauge  
• Use only 3-conductor (grounded) extension cord  
when necessary.  
• Check that the extension cord is properly wired and  
in good electrical condition.  
• Use the recommended minimum AWG (American  
Wire Gauge) to be sure that wire size is large  
enough for the rating of the charger.  
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.  
• Wear safety glasses. See additional “Personal  
Safety Precautions” on page 2.  
• Make sure that you have a 12 volt or 6 volt lead-acid  
battery. Set the volt/amp selector switch to match  
the voltage rating of the battery to be charged.  
• 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.  
• Clean the battery terminals. Be careful to keep  
corrosion from getting is or around your eyes.  
• 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.  
• 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.  
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, such as removing or not removing  
cell caps while charging, and recommended rates  
of charge.

Calculating charge times  
The Chart Method  
• Marine, or deep-cycle batteries are usually rated in  
Reserve Capacity (RC).  
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.  
NR means that the charger setting is NOT RECOM-  
MENDED.  
• Small batteries — motorcycles, garden tractors, etc.  
— are usually rated in Ampere Hours (AH). For  
example: 6, 12, 32 AH etc.  
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 severely dis-  
charged batteries.  
• Batteries in cars and smaller trucks are usually rated  
in Reserve Capacity (RC), Cold-Cranking Amps  
(CCA), or both.

To calculate time needed for a charge:  
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.  
• Find the percent of charge needed. (A battery at 50  
percent charge that will be charged to 100 percent

• Multiply the Amp Hour rating by the charge needed  
(.50) and divide by the charger setting (2, 20 or 60  
amps).  
• Multiply the result by 1.25 and you’ll have the time  
needed, in hours, to bring the battery to full charge.

When you know the percent of charge and the Amp  
Hour (AH) rating of your battery, you can calculate 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  
Battery for a little more than 3 hours at the 20-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 when  
using the ENGINE START feature.  
1. Set the POWER switch to the OFF position. Then  
follow the instructions for connecting the charger  
to the battery and power source in the section  
“Charging a battery in the vehicle.”  
5. Crank the engine for no more than 5 seconds. If  
it does not start, wait 4 minutes. (The display will  
show WAIT during this time and RDY when the  
time is up.)  
6. During extremely cold weather, or if the battery is  
severely exhausted, charge the battery for about 5  
minutes before cranking the engine.  
2. Set the BATTERY switch to 6V or 12V to match  
7. If the engine still does not start, charge the battery  
for five more minutes before cranking it again for  
three seconds.  
8. After the engine starts, unplug the charger power  
cord from the outlet. Then move the POWER  
switch to the OFF position before disconnecting  
the battery leads.  
the battery’s voltage.  
3. Set the POWER switch to the ON position. The  
METER display will show MAN (manual mode).  
4. Touch RESET, MANUAL and ENGINE START  
PADS in that order. Wait for the display to show  
RDY. The charger is now ready to have the  
engine cranked.  
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. The cords can be wrapped around  
the handle of the charger. This will help prevent  
accidental damage to the cords and charger.  
3. Occasional cleaning of the case with a soft cloth  
will keep the finish shiny and help prevent corro-  
sion.
