WARNING – RISK OF EXPLOSIVE GASES.
WORKING IN THE VICINITY OF A LEAD-ACID BATTERY IS DANGEROUS. BATTERIES GENERATE EXPLOSIVE GASES DURING NORMAL BATTERY OPERATION. FOR THIS REASON, IT IS OF UTMOST
IMPORTANCE THAT YOU FOLLOW THE INSTRUCTIONS EACH TIME
• 1 •
YOU USE THE CHARGER.
TO REDUCE THE RISK OF BATTERY EXPLOSION, FOLLOW THESE
INSTRUCTIONS AND THOSE PUBLISHED BY THE BATTERY MANUFACTURER AND THE MANUFACTURER OF ANY EQUIPMENT YOU
INTEND TO USE IN THE VICINITY OF THE BATTERY. REVIEW THE
CAUTIONARY MARKINGS ON THESE PRODUCTS AND ON THE
ENGINE.
PERSONAL PRECAUTIONS2.
Consider having someone close enough by to come to your aid when you 2.1
work near a lead-acid battery.
Have plenty of fresh water and soap nearby in case battery acid contacts 2.2
your skin, clothing or eyes.
Wear complete eye and body protection, including safety goggles and pro-2.3
tective clothing. Avoid touching your eyes while working near the battery.
If battery acid contacts your skin or clothing, wash immediately with soap 2.4
and water. If acid enters your eye, immediately ood the eye with cold running water for at least 10 minutes and get medical attention right away.
NEVER smoke or allow a spark or ame in the vicinity of a battery or 2.5
engine.
Be extra cautious to reduce the risk of dropping a metal tool onto the bat-2.6
tery. It might spark or short-circuit the battery or other electrical part that
may cause an explosion.
Remove personal metal items such as rings, bracelets, necklaces and 2.7
watches when working with a lead-acid battery. A lead-acid battery can
produce a short-circuit current high enough to weld a ring or the like to
metal, causing a severe burn.
Use this charger for charging a LEAD-ACID battery only. Do not use this 2.8
battery charger for charging dry-cell batteries that are commonly used with
home appliances. These batteries may burst and cause injury to persons
and damage to property.
NEVER charge a frozen battery.2.9
NEVER overcharge a battery.2.10
PREPARING TO CHARGE3.
If it is necessary to remove the battery from the vehicle to charge it, al-3.1
ways remove the grounded terminal rst. Make sure all of the accessories
in the vehicle are off, to prevent arcing.
Be sure the area around the battery is well ventilated while the battery is 3.2
being charged.
Clean the battery terminals before charging the battery. During cleaning, 3.3
keep airborne corrosion from coming into contact with your eyes, nose
and mouth. Use baking soda and water to neutralize battery acid and help
• 2 •
eliminate airborne corrosion. Do not touch your eyes, nose or mouth.
Add distilled water to each cell until the battery acid reaches the level 3.4
specied by the battery manufacturer. Do not overll. For a battery without
removable cell caps, such as valve regulated lead-acid-batteries, carefully
follow the manufacturer’s recharging instructions.
Read, understand and follow all instructions for the charger, battery, 3.5
vehicle and any equipment used near the battery and charger. Study all of
the battery manufacturer’s specic precautions while charging and recommended rates of charge.
Make sure that the charger cable clips make tight connections.3.6
CHARGER LOCATION4.
Locate the charger as far away from the battery as the DC cables permit.4.1
Never place the charger directly above the battery being charged; gases 4.2
from the battery will corrode and damage the charger.
Do not set the battery on top of the charger.4.3
Never allow battery acid to drip onto the charger when reading the electro-4.4
lyte specic gravity or lling the battery.
Do not operate the charger in a closed-in area or restrict the ventilation in 4.5
any way.
DC CONNECTION PRECAUTIONS5.
Connect and disconnect the DC output clips only after pressing the 5.1
START/STOP ( ) button to turn the output off and removing the AC plug
from the electrical outlet. Never allow the clips to touch each other.
Attach the clips to the battery and chassis, as indicated in steps 6.5, 6.6 5.2
and 7.2 through 7.4.
FOLLOW THESE STEPS WHEN BATTERY IS INSTALLED IN 6.

A SPARK NEAR THE BATTERY MAY CAUSE A BATTERY EXPLOSION. TO REDUCE THE RISK OF A SPARK NEAR THE BATTERY:
Position the AC and DC cables to reduce the risk of damage by the hood, 6.1
door and moving or hot engine parts.
Stay clear of fan blades, belts, pulleys and other parts that can cause 6.2
injury.
Check the polarity of the battery posts. The POSITIVE (POS, P, +) battery 6.3
post usually has a larger diameter then the NEGATIVE (NEG, N, -) post.
Determine which post of the battery is grounded (connected) to the chas-6.4
sis. If the negative post is grounded to the chassis (as in most vehicles),
see step 6.5. If the positive post is grounded to the chassis, see step 6.6.
• 3 •
For a negative-grounded vehicle, connect the POSITIVE (RED) clip from 6.5
the battery charger to the POSITIVE (POS, P, +) ungrounded post of the
battery. Connect the NEGATIVE (BLACK) clip to the vehicle chassis or
engine block away from the battery. Do not connect the clip to the carburetor, fuel lines or sheet-metal body parts. Connect to a heavy gauge metal
part of the frame or engine block.
For a positive-grounded vehicle, connect the NEGATIVE (BLACK) clip 6.6
from the battery charger to the NEGATIVE (NEG, N, -) ungrounded post
of the battery. Connect the POSITIVE (RED) clip to the vehicle chassis or
engine block away from the battery. Do not connect the clip to the carburetor, fuel lines or sheet-metal body parts. Connect to a heavy gauge metal
part of the frame or engine block.
When disconnecting the charger, press the START/STOP (6.7 ) button
to turn the output off, disconnect the AC cord, remove the clip from the
vehicle chassis and then remove the clip from the battery terminal.

A SPARK NEAR THE BATTERY MAY CAUSE A BATTERY EXPLOSION. TO REDUCE THE RISK OF A SPARK NEAR THE BATTERY:
Check the polarity of the battery posts. The POSITIVE (POS, P, +) battery 7.1
post usually has a larger diameter than the NEGATIVE (NEG, N, -) post.
Attach at least a 24-inch long 4 gauge (AWG) insulated battery cable to 7.2
the NEGATIVE (NEG, N, -) battery post.
Connect the POSITIVE (RED) charger clip to the POSITIVE (POS, P, +) 7.3
post of the battery.
Position yourself and the free end of the cable you previously attached to 7.4
the NEGATIVE (NEG, N, -) battery post as far away from the battery as
possible – then connect the NEGATIVE (BLACK) charger clip to the free
end of the cable.
Do not face the battery when making the nal connection.7.5
When disconnecting the charger, press the START/STOP (7.6 ) button to
turn the output off, disconnect the AC cord, remove the clip from the cable
attached to the negative battery terminal and then remove the clip from

ASSEMBLY INSTRUCTIONS8.4
This charger can be operated on a stable surface either upright or lying
down (brackets not installed). Rubber strips have been provided to help
prevent scratching and denting of the channels. If you would like to permanently mount the charger, use the following instructions:
Slide all 4 brackets (Item 1) into the track on the back, from the right 8.5
side, as shown above. Make sure the set screws (Item 2) are unscrewed
enough so they do not scratch the surface of the housing.
Measure what you are mounting the charger to before deciding where to 8.6
locate the brackets (add an additional ¼ to ½ inch). Use the ruler on the
label (Item 3) to mount the brackets (Item 1) in the correct position (position each bracket an equal distance from the center of the charger). Note
that the inches shown are for both bracket dimensions combined (meaning the dimensions are doubled), this is for easier reference. Make sure
the ¼-28 set screws (Item 4) are unscrewed enough so the pointed end is
almost ush with the bracket. Mount the brackets (Item 1) by tightening all
8 set screws (Item 2).
Lift the charger by its handle and set it against your mounting location, 8.7
• 6 •
tighten the set screws (Item 4) to secure the brackets (Item 1), starting
with the top two brackets rst.
CONTROL PANEL9.
CONNECTED (yellow) LED
The CONNECTED (yellow) LED will light when the battery is properly connected.
CHARGING (yellow) LED
When charging begins, the CHARGING (yellow) LED will light.
CHARGED (green) LED
The CHARGED (green) LED will light when the charger has gone into
maintain mode.
“UP” and “DOWN” ( and ) Buttons
Use these buttons to select the amount of time or voltage depending on
the display function selected.
Start/Stop ( ) Button
This is the start and stop button for all modes.
Digital Display
The Digital Display gives a digital indication of voltage, amperes or time,
depending on the DISPLAY function chosen.
Display Button
Use this button to set the function of the digital display to one of the following:
VOLTS (Voltmeter)•
The voltmeter indicates the voltage at the battery terminals. If the reading
is less than 10.5-volts, the battery may be bad or the connection at the
charger may be poor. If the reading is 10.5 volts to 12.7 volts the bat-
tery is low – recharge it. If the reading is 12.8 volts or more the battery is
charged.
AMPS (Ammeter)•
The Ammeter indicates the amount of current, measured in amps, that is
being drawn by the battery ( 2 amps). For example, in a 20 amp charge
rate a typical discharged battery will initially draw approximately 20 amps.
• 7 •
As the battery continues to charge the current will taper down. At full
charge, the battery may draw less than one amp.
NOTE: The 70 amp charge rate cycles between 20 amps and 70 amps
during the charging process and the ammeter will show this. This is a
normal condition.
TIME (Timer – Range: 10 min to 120 min)•
Used only in manual mode, the main function of the timer is to prevent
over charging while allowing a battery time to obtain a satisfactory
charge. To properly set the timer you must know the size of the battery
in ampere hours or reserve capacity in minutes and the state of charge.
Often the state of charge is not known, this is one reason why the timer
was limited to 2 hours. With the aid of a battery load tester the state of
charge can be obtained within a few seconds. For example, the aver-
age size automotive battery at a 50% state of charge will require 1 to 1½
hours of charging at a 40 amp rate to reach the full charge state. For the
same battery with the timer set to its maximum, 2 hours, over charging
will occur, but not likely to cause harm to a battery that was otherwise in
good condition. When the charge state is not known, start out with a timer
setting of one hour or less.
Hold:• This position defeats the timer function, allowing for continu-
ous operation. Use when you want to charge more than 2 hours. Be
sure to monitor the charging procedure and stop it when the battery
is charged. Not doing so may cause damage to your battery or may
cause other personal property damage or personal injury
MODE Button
Use this button to select between the AUTOMATIC CHARGE, MANUAL
CHARGE and FLASH REPROGRAM function. See Operating Instructions
section for details of these functions.
Battery Type Button
Use this button to set the type of battery to be charged to STANDARD or
GEL CELL.
Regular• – Set button to STANDARD. This battery type is usually used
in cars, trucks and motorcycles. These batteries have vent caps and are
often marked “Low Maintenance” or “Maintenance-free”. This type of
battery is designed to deliver quick bursts of energy (such as starting engines) and have a greater plate count. The plates will also be thinner and
have somewhat different material composition. Regular batteries should
not be used for deep cycle applications.
Deep-Cycle• – Set button to STANDARD. Deep-cycle batteries are usu-
ally marked as “Deep-Cycle” or “Marine”. Deep-cycle batteries are usually
larger than the other types. This type of battery has less instant energy
but somewhat greater long-term energy delivery than regular batteries.
Deep cycle batteries have thicker plates and can survive a number of
discharge cycles.
AGM• – Set button to STANDARD. The Absorbed Glass Matt construction
• 8 •
allows the electrolyte to be suspended in close proximity with the plate’s
active material. In theory, this enhances both the discharge and recharge
efciency. Actually, the AGM batteries are a variant of Sealed VRLA batteries. Popular usage high performance engine starting, power sports,
deep cycle, solar and storage battery. AGM batteries are typically good
deep cycle batteries and they deliver best life performance if recharged
before the battery drops below the 50 percent discharge rate. If these
AGM batteries are discharged to a rate of 100 percent the cycle life will
be 300 plus cycles and this is true of most AGM batteries rated as deep
cycle batteries.
GEL• – Set button to GEL CELL. The Gel Cell is similar to the AGM style
because the electrolyte is suspended, but different because technically
the AGM battery is still considered to be a wet cell. The electrolyte in a
GEL cell has a silica additive that causes it to set up or stiffen. The recharge voltages on this type of cell are lower than the other styles of lead
acid battery. This is probably the most sensitive cell in terms of adverse
reactions to over-voltage charging. Gel Batteries are best used in VERY
DEEP cycle application and may last a bit longer in hot weather applications. If the incorrect battery charger is used on a Gel Cell battery, poor
performance and premature failure is certain.
The Gel Cell and the AGM batteries are specialty batteries that typically
cost twice as much as a premium wet cell. However they store very well
and do not tend to sulfate or degrade as easily as a wet cell. There is little
chance of a hydrogen gas explosion or corrosion when using these batteries; these are the safest lead acid batteries you can use. Gel Cell and
some AGM batteries may require a special charging rate.
Charge Rate Button
Use this button to set the maximum charge rate to one of the following:
4A Charge Rate• – Intended for charging small batteries such as those
commonly used in garden tractors, snow mobiles and motorcycles.
20A and 70A Charge Rate• – Use for charging automotive and marine
batteries. Not intended for industrial applications.

may cause other personal property damage or personal injury.
Charging
If the charger does not detect a properly connected battery, the CON-
NECTED (yellow) LED will not light until such a battery is detected. Charging will not begin while the CONNECTED (yellow) LED is not on. When
charging begins, the CHARGING (yellow) LED will light.
Battery Percent and Charge Time
This charger adjusts the charging time in order to charge the battery completely, efciently and safely. The microprocessor automatically performs
the necessary functions. This section includes guidelines that can be used
to estimate charging times.
The duration of the charging process depends on these factors:
Battery State• – If a battery has only been slightly discharged, it can
be charged in less than a few hours. The same battery could take
up to 10 hours if very weak. The battery state can be estimated by
• 10 •
using the built-in voltage tester. The lower the reading the longer
charging will take.
Battery Rating• – A higher rated battery will take longer to charge
than a lower rated battery under the same conditions. A battery is
rated in ampere hours (AH), reserve capacity (RC) and cold cranking amps (CCA). The lower the rating the quicker the battery will
charge.
Charge Rate – The charge rate is measured in amps. This charger provides charge rates of 4A, 20A and 70A. The 4A rate is for charging smaller
batteries such as those used for motorcycles and garden tractors. Such
batteries should not be charged using the 20A or 70A rate. The 20A and
70A rates are for charging larger batteries. In the 20A and 70A mode, the
charger begins at a low-charge rate and increases the charge rate if it is
determined that the battery can accept the higher rate. All charging modes
will decrease the charge current as the battery approaches maximum
charge.
Automatic Charging Mode
When an automatic charge is performed, the charger switches to the
maintain mode automatically after the battery is charged. For a battery
with a starting voltage under 1 volt, press and hold the START/STOP
( ) button for ve seconds to start Automatic Charging, or use manual
mode to pre-charge the battery for ve minutes, to get additional voltage
into the battery for the charger to analyze.
Aborted Charge
If charging can not be completed normally, charging will abort. When
charging aborts, the charger’s output is shut off, the CHARGING (yellow)
LED will go out and the digital display will display . The charger ig-
nores all buttons except the START/STOP ( ) button in that state. Press
the START/STOP ( ) button to reset after an aborted charge.
Desulfation Mode
If the battery is left discharge for an extended period of time, it could
become sulfated and not accept a normal charge. If the charger detects
a sulfated battery, the charger will switch to a special mode of operation
designed for such batteries. Activation of the special desulfation mode is
indicated by the CHARGING (yellow) LED blinking. If successful, normal
charging will resume after the battery is desulfated. The CHARGING
(yellow) LED will then stop blinking and stay lit. Desulfation could take up
to 10 hours. If desulfation fails, charging will abort and the charger will go
into abort mode.
Completion of Charge
Charge completion is indicated by the CHARGED (green) LED. When lit,
the charger has stopped charging and switched to the Maintain Mode of
operation. If you are charging a deep cycle battery, the CHARGED (green)
LED comes on when the battery is charged enough for normal use.
