RISK OF ELECTRIC SHOCK OR FIRE.
1.1 Keep out of reach of children.
1.2 Do not expose the charger to rain or snow.
1.3 Use only recommended attachments. Use of an attachment
not recommended or sold by Schumacher®Electric Corporation
may result in a risk of re, electric shock or injury to persons or damage to property.
1.4 To reduce the risk of damage to the electric plug or cord, pull by the plug rather than the
cord when disconnecting the charger.
1.5 An extension cord should not be used unless absolutely necessary. Use of an improper
extension cord could result in a risk of re 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 specied
in section 8.
1.6 To reduce the risk of electric shock, unplug the charger from the outlet before attempting
any maintenance or cleaning. Simply turning off the controls will not reduce this risk.
1.7 Do not operate the charger with a damaged cord or plug; have the cord or plug replaced
immediately by a qualied service person.
1.8 Do not operate the charger if it has received a sharp blow, been dropped or otherwise
damaged in any way; take it to a qualied service person.
1.9 Do not disassemble the charger; take it to a qualied service person when service or repair
is required. Incorrect reassembly may result in a risk of re or electric shock.
RISK OF EXPLOSIVE GASES.
1.10 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 YOU
USE THE CHARGER.
1.11 To reduce the risk of a 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.

2. PERSONAL PRECAUTIONS
RISK OF EXPLOSIVE GASES.
2.1 NEVER smoke or allow a spark or ame in the vicinity of a battery or
engine.
2.2 Remove personal metal items such as rings, bracelets, necklaces and
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.
2.3 Be extra cautious, to reduce the risk of dropping a metal tool onto the battery. It might
spark or short-circuit the battery or other electrical part that may cause an explosion.
2.4 Use this charger for charging 12V LEAD-ACID batteries only. It is not intended 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.
2.5 NEVER charge a frozen battery.
2.6 NEVER overcharge a battery.
2.7 Consider having someone nearby to come to your aid when you work near a lead-acid battery.
2.8 Have plenty of fresh water and soap nearby in case battery acid contacts your skin,
clothing or eyes.
2.9 Wear complete eye and body protection, including safety goggles and protective clothing.
Avoid touching your eyes while working near the battery.
2.10 If battery acid contacts your skin or clothing, immediately wash the area with soap 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.
2.11 If battery acid is accidentally swallowed, drink milk, the whites of eggs or water. DO NOT
induce vomiting. Seek medical attention immediately.
3. PREPARING TO CHARGE
RISK OF CONTACT WITH BATTERY ACID. BATTERY ACID IS A
HIGHLY CORROSIVE SULFURIC ACID.
3.1 If it is necessary to remove the battery from the vehicle to
charge it, always remove the grounded terminal rst. Make sure all
of the accessories in the vehicle are off, to prevent arcing.
3.2 Be sure the area around the battery is well ventilated while
the battery is being charged.
3.3 Clean the battery terminals before charging the battery. During cleaning, 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.
3.4 Add distilled water to each cell until the battery acid reaches the level specied by the
battery manufacturer. Do not overll. For a battery without removable cell caps, such as
valve regulated lead-acid batteries (VRLA), carefully follow the manufacturer’s recharging
instructions.
3.5 Read, understand and follow all instructions for the charger, battery, vehicle and any
equipment used near the battery and charger. Study all of the battery manufacturer’s
specic precautions while charging and recommended rates of charge.
3.6 Determine the voltage of the battery by referring to the vehicle owner’s manual.
3.7 Make sure that the charger cable clips make tight connections.

•4 •
4. CHARGER LOCATION
RISK OF EXPLOSION AND CONTACT
WITH BATTERY ACID.
4.1 Locate the charger as far away from the
battery as the DC cables permit.
4.2 Never place the charger directly above the
battery being charged; gases from the battery will
corrode and damage the charger.
4.3 Do not set the battery on top of the charger.
4.4 Never allow battery acid to drip onto the charger when reading the electrolyte specic
gravity or lling the battery.
4.5 Do not operate the charger in a closed-in area or restrict the ventilation in any way.

OF A SPARK NEAR THE BATTERY:
6.1 Position the AC and DC cables to reduce the
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.
6.2 Stay clear of fan blades, belts, pulleys and other parts that can cause injury.
6.3 Check the polarity of the battery posts. The POSITIVE (POS, P, +) battery post usually
has a larger diameter than the NEGATIVE (NEG, N, -) post.
6.4 Determine which post of the battery is grounded (connected) to the chassis. 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.
6.5 For a negative-grounded vehicle, connect the POSITIVE (RED) clip from 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.
6.6 For a positive-grounded vehicle, connect the NEGATIVE (BLACK) clip 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.
6.7 Connect charger AC supply cord to electrical outlet.
6.8 When disconnecting the charger, turn all switches to off, disconnect the AC cord, remove
the clip from the vehicle chassis and then remove the clip from the battery terminal.
6.9 See CALCULATING CHARGE TIME for length of charge information.
7. FOLLOW THESE STEPS WHEN BATTERY IS OUTSIDE VEHICLE
A SPARK NEAR THE BATTERY MAY CAUSE A
BATTERY EXPLOSION. TO REDUCE THE RISK
OF A SPARK NEAR THE BATTERY:
7.1 Check the polarity of the battery posts. The
POSITIVE (POS, P, +) battery post usually has a
larger diameter than the NEGATIVE (NEG, N, -) post.
7.2 Attach at least a 24-inch (61 cm) long 6-gauge (AWG) insulated battery cable to the
NEGATIVE (NEG, N, -) battery post.

•5 •
7.3 Connect the POSITIVE (RED) charger clip to the POSITIVE (POS, P, +) post of the battery.
7.4 Position yourself and the free end of the cable you previously attached to 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.
7.5 Do not face the battery when making the nal connection.
7.6 Connect charger AC supply cord to electrical outlet.
7.7 When disconnecting the charger, always do so in the reverse order of the connecting
procedure and break the rst connection while as far away from the battery as practical.
7.8 A marine (boat) battery must be removed and charged on shore. To charge it onboard
requires equipment specially designed for marine use.
8. GROUNDING AND AC POWER CORD CONNECTIONS
RISK OF ELECTRIC SHOCK OR FIRE.
8.1 This battery charger is for use on a nominal 120 volt circuit
and has a grounded plug. 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 ordinances. The plug pins must t the receptacle
(outlet). Do not use with an ungrounded system.
8.2 Never alter the AC cord or plug provided – if it does not t the outlet,
have a proper grounded outlet installed by a qualied electrician. An improper connection
can result in a risk of an electric shock or electrocution. NOTE: The use of an adapter
plug is not recommended and should not be used.
8.3 Recommended minimum AWG size for extension cord:

minutes before cranking again.

•8 •
NOTE: During extremely cold weather, or if the battery is under 2 volts, charge the battery
for 5 minutes before cranking the engine.
7. If the engine fails to start, charge the battery for 5 more minutes before attempting to
crank the engine again.
8. After the engine starts, move the timer to the off position and unplug the AC power
cord before disconnecting the battery clips from the vehicle.
9. Clean and store the charger in a dry location.
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.
STARTER AND CHARGING SYSTEMS TEST PROCEDURES
When doing starter or charging tests, the Starter test must run rst, before the Alternator test.
Ensure that the charger remains UNPLUGGED for the entire duration of either test. Plug-
ging in the charger will automatically start charging the battery, and suspend the Starter or
Alternator test in progress. Any charging current detected will make the FAIL LED come
on by default, and invalidate test results.
NOTE: Starter and Alternator tests will become disabled and not run while charging is
taking place.
STARTER SYSTEM TEST PROCEDURE
1. With charger UNPLUGGED form the AC outlet, connect the tester clamps to the
battery following the precautions listed in section 6 and 7. Rock each clamp back and
forth to make a good connection.
NOTE: The battery must be good and fully charged for this test.
2. The battery voltage will appear on the LED display, unless the charger is plugged in, in
which case the charge current is displayed and the FAIL LED is lit. The Starter test will
be bypassed if attempting to select it, until current is removed. UNPLUG the charger.
The PASS/FAIL LEDs will alternate blinking until a crank event is detected.
3. Start the vehicle.
• Observe the nal cranking voltage that appears on the LED: If the Volts reading is
greater than 9.6 volts, the Starting System is OK. The PASS LED will light.
• If the Volts reading is less than 9.6 volts, there is a Starting System problem. The
FAIL LED will light.
NOTE: If charge voltage exceeds 19.9V, the FAIL LED lights to highlight a potentially
dangerous situation.
CHARGING SYSTEM (ALTERNATOR) TEST PROCEDURE
The Alternator test is normally selected AFTER the crank (Starter) test. If continuing from
a Starter test, with the vehicle still running, press the Function button to move from Starter
to Alternator test.
1. With charger UNPLUGGED form the AC outlet, connect the tester clamps to the
battery following the precautions listed in section 6 and 7. Rock each clamp back and
forth to make a good connection.
NOTE: The battery must be good and fully charged for this test.
2. The battery voltage will appear on the LED display, unless the charger is plugged in, in
which case the charge current is displayed and the FAIL LED is lit. The Alternator test
will be invalidated until current is removed. UNPLUG the charger.
3. Run the engine at 2000 rpm for 15 seconds. The PASS/FAIL LEDs will indicate the
result immediately. But as this is a semi-live result that will retain the highest measured
value, it is recommended to wait until this peak voltage stabilizes. If the value drifts into
the pass region, the PASS LED will light. If the value further drifts up and out of the
pass region, then the FAIL LED will stay lit.

•9 •
4. Observe the volts reading that appears on the LED:
• If the Volts reading is between 13.3 and 15.5 volts, the Charging System is OK.
The PASS LED will light.
• If the Volts reading is greater than 15.5 volts, there is a Charging System Problem.
The FAIL LED will light. Check regulator.
• If the Volts reading is less than 13.3 volts there is a Charging System Problem.
The FAIL LED will light. Check connections, wiring, and starter.
If charge voltage exceeds 19.9v, the FAIL LED lights to highlight a
potentially dangerous situation.
BATTERY CHARGE ACCEPTANCE TEST
NOTE: This is NOT the same as a conductance test.
1. With charger unplugged from the AC outlet, set both switches to TEST mode (point to
white battery illustration boxes on each dial).
2. Connect the tester clamps to the battery, following the precautions listed in sections 6
and 7.
(If polarity is reversed, attaching the second clamp will cause a spark. Reverse the
clamps.) The battery voltage will appear on the front panel display, and the PASS/FAIL
LEDs will blink alternatively until the 15 minute test time elapses.
NOTE: If charger detects more than 20 volts, the red FAIL light will illuminate and the
display will show 19.9. This may show on the display in BOOST CHARGE mode.
3. Plug charger into outlet, and the battery test will automatically begin. Because the test
starts the instant the charger is plugged in, be sure to PLUG THE CHARGER IN AS
SOON AS POSSIBLE AFTER HOOKING CABLES TO BATTERY.
It is suggested that you stay near the charger for the rst 15 minutes or so to monitor
test results. If the battery FAILS, it is not recommended to attempt to continue charging
a failed battery.
NOTE: To determine the difference between a BAD battery and one that fails simply
because it does not accept a charge, run another test with a dedicated battery tester.
The CXC6525 Digital Wheel Charger is not meant to replace a conductance battery
tester. Remove the battery from the charger for at least 4 hours before doing a
conductance test.
General Charging Notes
Fan: It is normal for the fan to be on all the time. Keep the area near the charger clear of
obstructions to allow the fan to operate efciently.
Voltage: The voltage displayed during charging is the charging voltage and is usually
higher than the battery’s resting voltage.
Charging Tips
Read this entire manual before using your battery charger. The following tips serve only
as a guide for specic situations.
• If your vehicle won’t start – It is not necessary to fully charge your battery to start a ve-
hicle. When the battery’s charge is 75% or more, the battery has usually been charged
enough for the vehicle to start and operate normally. If operating the vehicle continuous-
ly 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 operated
for a short period (short drive), the battery might need to be charged again before it
could start the vehicle again.

•10 •
13. CALCULATING CHARGE TIME
The Hydrometer or Electronic Method
To nd 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.
VOLTAGE
READING
SPECIFIC
GRAVITY
PERCENT
OF CHARGE
PERCENT OF
CHARGE NEEDED
12.65 1.265 100% 0%
12.45 1.225 75% 25%
12.06 1.155 25% 75%
11.89 or less 1.120 0% 100%
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:
Example:
Amp Hour Rating = Reserve Capacity + 16
2
NOTE: The Reserve Capacity can be obtained from the battery specication sheet or the
owner’s manual.
To calculate the time needed for a charge:
1. Find the percent of charge needed. (A battery at 50 percent charge that will be
charged to 100 percent needs another 50 percent).
2. Multiply the Amp Hour Rating by the charge needed (.50) and divide by the charge
rate setting.
3. Multiply the results by 1.25 and you will have the total time needed, in hours, to bring
the battery to full charge.
4. Add an additional hour for a deep-cycle battery.
Example:
Amp Hour Rating x % of charge needed x 1.25 = hours of charge
Charge Rate Setting
100 (Ah Rating) x 0.50 (charge needed) x 1.25 = 1.56 hours
40 (Charge Rate Setting)
100 x 0.50 x 1.25 = 1.56
40
You would need to charge your 100-Ampere Hour Battery for a little less than 2 hours at
the 40 Amp charge rate using the above example.

•11 •
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 ts into the chart.
CCA = Cold Cranking Amps
RC = Reserve Capacity
Ah = Amp Hour
NR means that the charger setting is NOT RECOMMENDED.
Next, nd 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.

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.
17.2 When a battery is very cold, partially charged or sulfated, it will not draw the full rated
amperes from the charger. It is both dangerous and damaging to a battery to force higher
amperage into it than it can effectively use in recharging.
17.3 When an UNKNOWN OPERATING PROBLEM arises, please read the complete manual
and call our customer service number for assistance. This 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.
