IMPORTANT SAFETY INSTRUCTIONS1.
SAVE THESE INSTRUCTIONS – The SE and SF series chargers offer1.1
a wide range of features to accommodate your needs. This manual will
show you how to use your charger safely and effectively. Please read,
understand and follow these instructions and precautions carefully, as this
manual contains important safety and operating instructions.
WARNING: Pursuant to California Proposition 65, this product contains1.2
chemicals known to the State of California to cause cancer and birth de-
fects or other reproductive harm.
Do not expose the charger to rain or snow.1.3
Use only recommended attachments. Use of an attachment not recom-1.4
mended or sold by Schumacher® Electric Corporation may result in a risk
of fire, electric shock or injury to persons or damage to property.
To reduce the risk of damage to the electric plug or cord, pull by the plug1.5
rather than the cord when disconnecting the charger.
An extension cord should not be used unless absolutely necessary. Use of1.6
an improper extension cord could result in a risk of fire and electric shock.
If an extension cord must be used, make sure:
That the pins on the plug of the extension cord are the same number,•
size and shape as those of the plug on the charger.
That the extension cord is properly wired and in good electrical condition.•
That the wire size is large enough for the AC ampere rating of the charger•
as specified in the table in Section 8.2.
Do not operate the charger with a damaged cord or plug; take it to a quali-1.7
fied service person. (Call customer service at: 1-800-621-5485.)

or otherwise damaged in any way; take it to a qualified service person.
(Call customer service at: 1-800-621-5485.)
Do not disassemble the charger; take it to a qualified service person when1.9
service or repair is required. Incorrect reassembly may result in a risk of
fire or electric shock. (Call customer service at: 1-800-621-5485.)
To reduce the risk of electric shock, unplug the charger from the outlet1.10
before attempting any maintenance or cleaning. Simply turning off the
controls will not reduce this risk.
WARNING – RISK OF EXPLOSIVE GASES.
WORKING IN THE VICINITY OF A LEAD-ACID BATTERY IS DANGER-
OUS. BATTERIES GENERATE EXPLOSIVE GASES DURING NOR-
MAL BATTERY OPERATION. FOR THIS REASON, IT IS OF UTMOST
IMPORTANCE THAT YOU FOLLOW THE INSTRUCTIONS EACH TIME
YOU USE THE CHARGER.

•2 •
TO REDUCE THE RISK OF A BATTERY EXPLOSION, FOLLOW THESE
INSTRUCTIONS AND THOSE PUBLISHED BY THE BATTERY MANU-
FACTURER 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 you2.1
work near a lead-acid battery.
Have plenty of fresh water and soap nearby in case battery acid contacts2.2
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, immediately wash the area2.4
with soap and water. If acid enters your eye, immediately flood the eye
with cold running water for at least 10 minutes and get medical attention
right away.
NEVER smoke or allow a spark or flame in the vicinity of a battery or2.5
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 and2.7
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 LEAD-ACID batteries only. It is not intended2.8
to supply power to a low voltage electrical system other than in a starter-
motor application. Do not use this 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 first. 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 is3.2
being charged.

•3 •
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 the battery acid and
help eliminate airborne corrosion. Do not touch your eyes, nose or mouth.
Add distilled water to each cell until the battery acid reaches the level3.4
specified by the battery manufacturer. Do not overfill. For a battery without
removable cell caps, such as valve regulated lead acid batteries (VRLA),
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 specific precautions while charging and recom-
mended rates of charge.
Determine the voltage of the battery by referring to the vehicle owner’s3.6
manual and make sure that the output voltage selector switch is set to the
correct voltage. If the charger has an adjustable charge rate, charge the
battery in the lowest rate first.
Make sure that the charger cable clips make tight connections.3.7
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; gases4.2
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 specific gravity or filling the battery.
Do not operate the charger in a closed-in area or restrict the ventilation in4.5
any way.
DC CONNECTION PRECAUTIONS5.
Connect and disconnect the DC output clips only after setting all of the5.1
charger switches to the “off” position 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, 6.65.2
and 7.2 through 7.4.
FOLLOW THESE STEPS WHEN BATTERY IS INSTALLED IN6.
VEHICLE.
A SPARK NEAR THE BATTERY MAY CAUSE A BATTERY EXPLO-
SION. 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 cause6.2
injury.

•4 •
Check the polarity of the battery posts. The POSITIVE (POS, P, +) battery6.3
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.
For a negative-grounded vehicle, connect the POSITIVE (RED) clip from6.5
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 carbure-
tor, 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) clip6.6
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 carbure-
tor, fuel lines or sheet-metal body parts. Connect to a heavy gauge metal
part of the frame or engine block.
When disconnecting the charger, turn all switches to off, disconnect the6.7
AC cord, remove the clip from the vehicle chassis and then remove the
clip from the battery terminal.
See CALCULATING CHARGE TIME for length of charge information.6.8
FOLLOW THESE STEPS WHEN BATTERY IS OUTSIDE VEHICLE.7.
A SPARK NEAR THE BATTERY MAY CAUSE A BATTERY EXPLO-
SION. TO REDUCE THE RISK OF A SPARK NEAR THE BATTERY:
Check the polarity of the battery posts. The POSITIVE (POS, P, +) battery7.1
post usually has a larger diameter than the NEGATIVE (NEG, N, -) post.
Attach at least a 24-inch long 6-gauge (AWG) insulated battery cable to7.2
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 to7.4
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 final connection.7.5
When disconnecting the charger, always do so in the reverse order of the7.6
connecting procedure and break the first connection while as far away
from the battery as practical.
A marine (boat) battery must be removed and charged on shore. To7.7
charge it onboard requires equipment specially designed for marine use.

•5 •
BATTERY CHARGING – AC CONNECTIONS8.
This battery charger is for use on a nominal 120-volt8.1
circuit and has a grounded plug that looks like the
plug illustrated. The charger must be grounded to
reduce the risk of electric shock. The plug must be
plugged into an outlet that is properly installed and
grounded in accordance with all local codes and ordi-
nances. The plug pins must fit the receptacle (outlet).
Do not use with an ungrounded system.
DANGER – Never alter AC cord or plug provided – if it does not fit the
outlet, have proper grounded outlet installed by a qualified electrician. Im-
proper connection can result in a risk of an electric shock or electrocution.
NOTE: The use of an adapter plug is not recommended.

Ammeter
The Ammeter indicates the amount of current, measured in amps, that is
being drawn by the battery. For example, in a 10 amp charge rate a typical
discharged battery will initially draw approximately 10 amps. As the battery
continues to charge the current will taper down. At full charge, the battery
may only draw a few amps. The start area of the meter indicates a high
rate of current being drawn from the charger. When cranking an engine,
the meter needle will be at the extreme right side of the start area. Some-
times for the first few minutes of its charge a battery will draw more than
70 amps, in this case the needle may be within, but not all the way over,
to the right side of the start area. The 2 amp charge rate may indicate
some activity on the meter although the meter does not have the resolu-
tion to display this low rate. For the 2 amp charge rate, a triangle has been
provided. Its accuracy has been calibrated for use with small batteries. As
a battery takes on a charge, it draws less current from the charger. Cor-
respondingly less of the triangle will fall under the meter needle.

Percent of Charge•
The percent of charge scale is intended as a visual aid to help simplify
reading the state of charge. It is scaled for use with the 6, 10, 12, 15 or
30 amp charge rate only. For the 2 amp charge rate use the triangle.
The percent of charge is based on the current drawn by the battery. For
this reason accuracy will vary with the size and battery type. Typically a
28 ampere hour gel cell battery will draw less current at the end of the
charge cycle than a 140 ampere hour wet cell battery. This means that
the indication for a fully charged large battery may be slightly less than
100%.
Battery Type Switch
Three basic types of lead-acid batteries can be charged with these char-
gers. Use this button to set the type of battery to be charged. If you are not
sure of your battery type, use the Conventional setting.
Conventional and Low Maintenance Batteries –• These are antimony/
lead batteries. Conventional/Low Maintenance batteries require periodic
addition of water to the acid solution (electrolyte). Additional water may
be added by removing the filler caps located on the top of the battery.
When antimony is known to be one of the materials used in the battery’s
construction, that battery is conventional/low maintenance type.
CAUTION: Some low maintenance batteries have a relatively smooth top
without any apparent battery filler caps. If, however, the battery manufac-
turer/distributor recommends periodic checking of the electrolyte level and
provides access to the battery for water additions, the battery is probably a
conventional/low maintenance type.
Maintenance Free –• These are calcium/lead batteries. They normally
do not require water additions. Therefore, filler caps have been removed
from the battery surface. These batteries will have a smooth or sealed
appearance.
Deep-Cycle• – Deep-cycle batteries are usually 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.
Charge Rate Selector Switch (Voltage/Amp Selector)
Use this switch to set the maximum charge rate to one of the following.
2A Slow Charge Rate• – Intended for charging small batteries such as
those commonly used in garden tractors, snow mobiles and motorcycles.
The 2A rate can be used to warm or trickle charge larger batteries.
6A, 10A, 12A, 15A Fast and 30A Rapid Charge Rate• – Use for charging
automotive, marine and deep-cycle batteries. Not intended for industrial
applications.

•9 •
Engine Start• – Provides additional amps for cranking an engine with a
weak or run down battery. Always use in combination with a battery.
Voltage Selector switch
Use this switch to set the charger to charge a 6 volt, 12 volt or 24 volt bat-
tery.
NOTE: These chargers are not recommended for 8 or 16 volt systems.
LED Indicators
Full Charge• – When lit, this LED indicates that the battery is fully
charged and the charger has stopped charging and switched to the Main-
tain Mode of operation (Automatic Mode Only).
Power On• – When lit, this LED indicates that there is AC power supplied
to the battery charger.
Check Battery• – When lit, this LED indicates there is something wrong
with the battery. Check the DC connections for an improper connection;
otherwise the battery may be bad.
OPERATING INSTRUCTIONS11.
Overview
Connect the battery following the precautions listed in Sections 6 and1.
7.
Select the appropriate settings for your battery.2.
Connect the AC power following the precautions listed in Section 8.3.
Charging
Indication of a Fully Charged Battery:•
A hydrometer reading of the specific gravity of the electrolyte (fluid) of a
battery in good condition should be between 1.250 and 1.285. When a
battery reaches 80 to 85% of a full charge, bubbles will appear on the
surface of the fluid. As the battery nears full charge, the bubbling will
become more active. At no time during the charge cycle should there be
any sign of vigorous bubbling of the battery fluid.
There are some important facts to keep in mind when charging a•
battery.
When the battery reaches 77% charged, it has been chargedО
enough to start most vehicles.
The charge % shown is an estimate of the relative charge inО
the battery compared to the charge it should have if the charging
process is allowed to complete and can be used to estimate the
relative charge time. The lower the charge % shown the longer the
charge time for a given battery.
The charge % shown is an indication of the relative progress ofО
the charging process. The higher the charge % displayed, the less
charge time remains.

•10 •
The more a battery is discharged, the faster it absorbs chargeО
from a charger. That means that the charge % increases faster
at the beginning of the charging process than at the end. In other
words, it takes longer for the battery to absorb the last few per-
cents of charge than the first several percents.
Automatic Charging
If the charger has an Automatic Charge Mode, it can perform an automatic
charge. When an Automatic Charge is performed, the charger switches to
the Maintain Mode (see below) automatically after the battery is charged.
For a battery with a starting voltage under 1 volt, use the Manual Mode
first to pre-charge the battery for five minutes, to get additional voltage into
the battery for the charger to analyze.
Manual Charging
If the charger does not have an Automatic Charge Mode, you will be
charging in Manual Mode. A manual charger will continue to charge
and will not shut off. You must keep a visual check on the ammeter to
determine when the battery is charged. Be sure to monitor the charging
process and stop it when the battery is charged. Not doing so may cause
damage to your battery or result in other property damage or personal
injury.
Completion of Charge (Automatic Chargers Only)
When the FULL CHARGE (green) LED is lit, the charger has stopped
charging and switched to the Maintain Mode of operation. If the 12V DEEP
CYCLE battery type was selected, the CHARGED (green) LED comes on
when the battery is charged enough for normal use.
Maintain Mode
When the FULL CHARGE (green) LED is lit, the charger has started
Maintain Mode. In this mode, the charger keeps the battery fully charged
by delivering a small current, when necessary. If the battery voltage drops
below a preset level the charger will go back into charge mode until the
battery voltage returns to the full charge level, at which point the charger
will return to maintain mode. The voltage is maintained at a level deter-
mined by the BATTERY TYPE selected.
NOTE: The charger automatically switches between Charge Mode and
Maintain Mode as necessary. The FULL CHARGE (green) LED will cycle
on when the battery is at full charge and off when the voltage drops below
a preset level and the charger goes into Charge Mode. This cycle will con-
tinue, and the FULL CHARGE (green) LED will stay on for longer periods
of time as the battery becomes more fully charged.
Using the Engine Start feature (If equipped)
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.
IMPORTANT: Follow all safety instructions and precautions for charg-
ing your battery. Wear complete eye protection and clothing protection.
Charge your battery in a well-ventilated area.

•11 •
IMPORTANT: Using the ENGINE START feature WITHOUT a battery
installed in the vehicle could cause damage to the vehicle’s electrical
system.

hicle, set the charge rate selector switch to the engine start position.
Crank the engine until it starts or 5 seconds passes. If the engine does5.
not start, wait 3 minutes before cranking again. This allows the battery
and the charger to cool down.
NOTE: During extremely cold weather, or if the battery is under 2 volts,
charge the battery for 5 minutes before cranking the engine.
If the engine fails to start, charge the battery for 5 more minutes before6.

After the engine starts, move the amp rate selector switch to the off po-7.
sition and unplug the AC power cord before disconnecting the battery
clips from the vehicle.
Clean and store the charger in a dry location.8.
NOTE: If the engine does turn over, but never starts, there is not a prob-
lem with the starting system; there is a problem somewhere else with
the vehicle. STOP cranking the engine until the other problem has been
diagnosed and corrected.
Charging Tips
Read this entire manual before using your battery charger. The following
tips serve only as a guide for specific situations.
If your vehicle won’t start• – It is not necessary to fully charge your bat-
tery to start a vehicle. When the battery’s charge is 77% or more, the bat-
tery has usually been charged enough for the vehicle to start and operate
normally. If operating the vehicle continuously for an extended period
(such as a long drive), the vehicle’s charging system should charge the
battery back to normal during that period. If the vehicle will only be oper-
ated for a short period (short drive), the battery might need to be charged
again before it could start the vehicle again.
Completing an interrupted charge (Automatic Chargers Only)• – Once
the battery has reached 85% charge; if the charging process is inter-
rupted and restarted, the charger could go straight into Maintain Mode.
However, if the original charge was started using the 6, 10, 12, 15 or 30A
rate, the charge can often be completed using the 2A rate.

•12 •
CALCULATING CHARGE TIME12.
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.
Cold cranking amps (CCA) is a measurement of the number of amps a
battery can deliver at 0° F for 30 seconds and not drop below 7.2 volts. So
a high CCA battery rating is good especially in cold weather.
Reserve Capacity (RC) is a very important rating. This is the number of
minutes a fully charged battery at 80° F will discharge 25 amps until the
battery drops below 10.5 volts.
An amp hour (AH) is a rating usually found on deep cycle batteries. If a
battery is rated at 100 amp hours it should deliver 5 amps for 20 hours, 20
amps for 5 hours, etc.
NR means that the charger setting is NOT RECOMMENDED.
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% charge prior to recharging. Add more time for severely discharged
batteries.

MAINTENANCE INSTRUCTIONS13.
Before performing maintenance, unplug and disconnect battery charger13.1
(see Sections 6.7 and 7.6).
After use, unplug charger and use a dry cloth to wipe all battery corrosion13.2
and other dirt or oil from terminals, cords, and the charger case.

•13 •
Servicing does not require opening unit, as there are no user-serviceable13.3
parts.
STORAGE INSTRUCTIONS14.
Store charger unplugged, in an upright position. Cord will still conduct14.1
electricity until it is unplugged from outlet.
Store inside, in a cool, dry place (unless you’re using an on-board Marine14.2
Charger).
Do not store clips on handle, clipped together, on or around metal, or14.3
clipped to cables.
TROUBLESHOOTING15.
PROBLEM POSSIBLE CAUSE REASON/SOLUTION
No reading on the am-
meter. Charger is not plugged in.
No power at the receptacle.
Clips are not making a
good connection to the
battery.
Connections are reversed.
Battery is defective (will not
accept a charge).
2 amp charge rate is being
used.
Plug the charger into an AC
outlet.
Check for open fuse or
circuit breaker supplying AC
outlet.
Check for poor connection
to battery and frame. Make
sure connection points are
clean. Rock clips back and
forth for a better connection.
Unplug the charger and
reverse the clips.
Have battery checked.
Ammeter may show no ac-
tivity at the 2A charge rate.
Ammeter reading stays
high. Battery is severely dis- charged.
Wrong battery voltage.
Continue charging bat-
tery for two more hours. If
problem continues have the
battery checked.
Verify the voltage settings
on the charger are correct.
Charger will not turn on
when properly connected. AC outlet is dead.
Poor electrical connection.
Check for open fuse or
circuit breaker supplying AC
outlet.
Check power cord and
extension cord for loose
fitting plug.
The battery is connected
and the charger is on, but
is not charging.
Clips are not making a
good connection. Check for poor connection at battery and frame. Make
sure connecting points are
clean. Rock clips back and
forth for a better connection.

•14 •
PROBLEM POSSIBLE CAUSE REASON/SOLUTION
The measured current is
much lower than what was
selected.
The charger reached the
maximum voltage and is
reducing the current.
No problem, this is a normal
condition.
Ammeter reads less than
selected charge rate when
charging a discharged
battery
Extension cord is too long
or wire gauge is too small.
Weak cell or sulfated plate
in battery.
Battery is only partially
discharged.
Use a shorter or heavier
gauge extension cord.
A sulfated battery will even-
tually take a normal charge
if left connected. If the bat-
tery will not take a charge,
have it checked.
Continue to charge the
battery.
The charger is making an
audible clicking sound. Circuit breaker is cycling.
Battery is defective.
Shorted battery cables or
clips.
Severely discharged bat-
tery, but otherwise it is a
good battery.
Reverse connections at
battery.
The settings may be wrong.
Check the charger settings.
Have the battery checked.
Circuit breaker cycles when
current draw is too high.
Check for shorted cables or
clips and replace if neces-
sary.
The battery may not want
to accept a charge due to
a run-down state. Allow
charging to continue until
battery has a chance to
recover sufficiently to take
a charge. If more than 20
minutes, stop charging and
have the battery checked.
Shut the charger off and
correct the lead connec-
tions.
Charger makes a loud
buzz or hum. Transformer laminations vibrate (buzz).
Shorted Diode Assembly or
Output Rectifier Assembly
(hum).
No problem, this is a normal
condition.
Have charger checked by a
qualified technician.

•15 •
PROBLEM POSSIBLE CAUSE REASON/SOLUTION
Short or no start cycle
when cranking engine. Drawing more than the Engine Start Rate.
Failure to wait 3 minutes
(180 seconds) between
cranks.
Clips are not making a
good connection.
AC cord and/or extension
cord is loose.
No power at receptacle.
The charger may be over-
heated.
Battery may be severely
discharged.
Crank time varies with the
amount of current drawn. If
cranking draws more than
the Engine Start Rate, crank
time may be less than 3
seconds.
Wait 3 minutes of rest time
before the next crank to al-
low the battery and charger
to cool down.
Check for poor connection
at battery and frame.
Check power cord and
extension cord for loose
fitting plug.
Check for open fuse or
circuit breaker supplying AC
outlet.
The thermal protector may
have tripped and needs a
little longer to close. Make
sure the charger vents are
not blocked. Wait and try
again.
On a severely discharged
battery, charge for 10 to
15 minutes in the highest
manual rate to help assist in
cranking.
BEFORE RETURNING FOR REPAIRS16.
When a charging problem arises, make certain that the battery is capable16.1
of accepting a normal charge. Use a good battery to double check all
connections, AC outlet for a full 120-volts, charger clips for correct polarity
and the quality of the connections from the cables to the clips and from the
clips to the battery system. The clips must be clean.
When a battery is very cold, partially charged or sulfated, it will not draw16.2
the full rated amperes from the charger. It is both dangerous and damag-
ing to a battery to force higher amperage into it than it can effectively use
in recharging.
When an UNKNOWN OPERATING PROBLEM arises, please read the16.3
complete manual and call the customer service number for information
that will usually eliminate the need for return.
If the above solutions do not eliminate the problem or for information about troubleshooting
or replacement parts, call toll-free from anywhere in the U.S.A.
