RISK OF EXPLOSIVE GASES.
WORKING IN THE VICINITY OF A LEAD-ACID BATTERY IS 1.10
DANGEROUS. BATTERIES GENERATE EXPLOSIVE GASES DURING
NORMAL BATTERY OPERATION. FOR THIS REASON, IT IS OF UTMOST
IMPORTANCE THAT YOU FOLLOW THE INSTRUCTIONS EACH TIME YOU
USE THE CHARGER.
To reduce the risk of a battery explosion, follow these instructions and those published by 1.11
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.
This charger employs parts, such as switches and circuit breakers, that tend to produce arcs 1.12
and sparks. If used in a garage, locate this charger 18 inches or more above oor level.
PERSONAL PRECAUTIONS2.
RISK OF EXPLOSIVE GASES.
NEVER smoke or allow a spark or ame in the vicinity of a battery or engine.2.1
Remove personal metal items such as rings, bracelets, necklaces and 2.2
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.
Be extra cautious to reduce the risk of dropping a metal tool onto the battery. It might 2.3
spark or short-circuit the battery or other electrical part that may cause an explosion.
Use this charger for charging LEAD-ACID batteries only. It is not intended to supply power 2.4
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.2.5
NEVER overcharge a battery.2.6
Consider having someone close enough by to come to your aid when you work near a 2.7
lead-acid battery.
Have plenty of fresh water and soap nearby in case battery acid contacts your skin, 2.8
clothing or eyes.
Wear complete eye and body protection, including safety goggles and protective 2.9
clothing. Avoid touching your eyes while working near the battery.
If battery acid contacts your skin or clothing, immediately wash the area with soap and 2.10
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.
If battery acid is accidentally swallowed, drink milk, the whites of eggs or water. DO NOT 2.11
induce vomiting. Seek medical attention immediately.
PREPARING TO CHARGE3.
RISK OF CONTACT WITH BATTERY ACID. BATTERY ACID IS
A HIGHLY CORROSIVE SULFURIC ACID.
If it is necessary to remove the battery from the vehicle to 3.1
charge it, always 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 3.2
while the battery is being charged.
Clean the battery terminals before charging the battery. During cleaning, keep airborne 3.3
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 level specied by the 3.4
battery manufacturer. Do not overll. 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, vehicle and any 3.5
equipment used near the battery and charger. Study all of the battery manufacturer’s
specic precautions while charging and recommended rates of charge.
• 2 •
Determine the voltage of the battery by referring to the vehicle owner’s manual and make 3.6
sure that the output voltage selector switch is set to the correct voltage (if applicable). If
the charger has an adjustable charge rate, charge the battery in the lowest rate rst.
Make sure that the charger cable clips make tight connections.3.7
CHARGER LOCATION4.
RISK OF EXPLOSION AND CONTACT WITH
BATTERY ACID.
Locate the charger as far away from the 4.1
battery as the DC cables permit.
Never place the charger directly above the 4.2
battery being charged; gases 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 electrolyte specic 4.4
gravity or lling the battery.
Do not operate the charger in a closed-in area or restrict the ventilation in any way.4.5
DC CONNECTION PRECAUTIONS5.
Connect and disconnect the DC output clips only after setting all of the charger switches 5.1
to the “off” position (if applicable) 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 sections 6 and 7.5.2
FOLLOW THESE STEPS WHEN BATTERY IS INSTALLED IN VEHICLE6.
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 6.1
risk of damage by the hood, door and moving or hot
engine parts. NOTE: If it is necessary to close the
hood during the charging process, ensure that the hood does not touch the metal part of
the battery clips or cut the insulation of the cables.
Stay clear of fan blades, belts, pulleys and other parts that can cause injury.6.2
Check the polarity of the battery posts. The POSITIVE (POS, P, +) battery post usually 6.3
has a larger diameter then the NEGATIVE (NEG, N, -) post.
Determine which post of the battery is grounded (connected) to the chassis. If the 6.4
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 from the battery 6.5
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 from the battery 6.6
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.
Connect charger AC supply cord to electrical outlet.6.7
When disconnecting the charger, turn all switches to off (if applicable), disconnect the 6.8
AC cord, remove the clip from the vehicle chassis and then remove the clip from the
battery terminal.

FOLLOW THESE STEPS WHEN BATTERY IS OUTSIDE VEHICLE7.
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 7.1
POSITIVE (POS, P, +) battery post usually has a
larger diameter than the NEGATIVE (NEG, N, -) post.
Attach at least a 24-inch (61 cm) long 6-gauge (AWG) insulated battery cable to the 7.2
NEGATIVE (NEG, N, -) battery post.
Connect the POSITIVE (RED) charger clip to the POSITIVE (POS, P, +) post of the battery.7.3
Position yourself and the free end of the cable you previously attached to the NEGATIVE 7.4
(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
Connect charger AC supply cord to electrical outlet.7.6
When disconnecting the charger, always do so in the reverse order of the connecting 7.7
procedure and break the rst connection while as far away from the battery as practical.

Battery Connection Indicator
If the charger does not detect a properly connected battery, the CONNECTED LED
will not light. Charging will not begin if the CONNECTED LED is not on.
Automatic Charging Mode
When an Automatic Charge is performed, the charger switches to the Maintain Mode
(see below) automatically after the battery is charged.
Aborted Charge
If charging cannot be completed normally, charging will abort. When charging aborts,
the charger’s output is shut off, all of the LEDs are turned off and the digital display
will show an error code (see Troubleshooting for a list of error codes). In that state, the
charger ignores all buttons. To reset after an aborted charge, unplug the charger.
Completion of Charge
Charge completion is indicated by the CHARGED LED . When lit, the charger has
switched to the Maintain Mode of operation.
Maintain Mode (Float-Mode Monitoring)
When the CHARGED 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. The voltage is maintained at a level determined by the BATTERY TYPE
selected. If the charger has to provide its maximum maintain current for a continuous
12 hour period, it will go into Abort Mode (see Aborted Charge section). This is usually
caused by a drain on the battery, or the battery could be bad. Make sure there are
no loads on the battery. If there are, remove them. If there are none, have the battery
checked or replaced.
NOTE: For 12V AGM and 12V GEL CELL battery types, the CHARGED LED might
be lit before the Maintain Mode starts.
Maintaining a Battery (3A Charge Rate)
The Schumacher XC75 and XC103 are battery chargers with a maintenance setting that
maintains both 6 and 12 volt batteries, keeping them at full charge. On this setting, it can
charge small batteries and maintain both small and large batteries. If you are maintaining
a fully charged large battery, you will properly utilize the maintenance setting. However, if
you use the maintenance setting to charge a large battery, such as a marine deep cycle
battery, that was not fully charged, you may lose some of the battery’s capacity. This would
• 6 •
cause the large battery to be unable to hold a charge and become useless. Therefore, we
do not recommend charging a large battery on the maintenance setting.
NOTE: The maintain mode technology utilized in Schumacher’s chargers allows you
to safely charge and maintain a healthy battery for extended periods of time. However,
problems with the battery, electrical problems in the vehicle, improper connections
or other unanticipated conditions could cause excessive current draws. As such,
occasionally monitoring your battery and the charging process is recommended.
Using the Engine Start feature
Your battery charger can be used to jumpstart your car if the battery is low. Follow these
instructions on how to use the ENGINE START feature.
Wear complete eye protection and clothing protection. Charge your battery in a well-

or it could damage the vehicle’s electrical system.
With the charger plugged in and connected to the battery and chassis (see section 1.
6), press the CHARGE RATE button until the ENGINE START LED is lit.
Crank the engine until it starts or 3 seconds pass. If the engine does not start, wait 3 2.
minutes before cranking again. This allows the charger and battery 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 before attempting to 3.
crank the engine again.
After the engine starts, move the charge rate selector switch to the off position and 4.
unplug the AC power cord before disconnecting the battery clips from the vehicle.
Clean and store the charger in a dry location.5.
NOTE: If the engine does turn over but never starts, there is not a problem 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.
Engine Starting Notes
During the starting sequence listed above, the charger is set to one of three states:
Wait for cranking – The charger waits until the engine is actually being cranked before
delivering the amps for engine start and will reset if the engine is not cranked within 15
minutes. (If the charger resets, it sets itself to the default start up settings). While waiting
for cranking, the digital display shows rdy.
Cranking – When cranking is detected, the charger will automatically deliver up to its
maximum output as required by the starting system for up to 3 seconds or until the engine
cranking stops. The digital display shows a countdown of the remaining crank time.
Cool Down – After cranking, the charger enters a mandatory 3 minute (180 second)
cool down state. The digital display indicates the remaining cool down time in seconds.
It starts at 180 and counts down to 0. After 3 minutes, the digital display will change from
displaying the countdown to displaying rdy. The CHARGING LED will then be lit.
