PERSONAL SAFETY PRECAUTIONS
• Wear complete eye and clothing
protection when working with lead-
acid batteries.
• 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.
• Make 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.
• 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.
• 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.
• Always operate the battery charger in
an open, well-ventilated area.
• 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 smoke or allow a spark or
flame in the vicinity of the battery or
engine. Batteries generate explosive
gases.
• Neutralize any acid spills thoroughly
with baking soda before attempting to
clean up.
• Never charge a frozen battery.

you follow these guidelines:
PLUGGING IT IN
Your charger requires a 120V AC
receptacle installed according to all local
codes and ordinances.
• Make sure that pins on plug of
extension cord are the same number,
size, and shape as those of plug on
charger.
• Check that the extension cord is
properly wired and in good electrical
condition.
• Make sure that the wire size is large
enough for its length and for the AC
ampere rating, as specified in the
chart below.

PREPARING YOUR BATTERY TO BE CHARGED
It is important that you read and follow these guidelines while you are preparing to
charge the battery.
• Make sure that you have a 12 volt
lead-acid battery. Determine voltage
of battery by referring to vehicle
owner’s manual. Charge battery
initially at charger’s lowest rate.
• Take time to read all of the battery
manufacturer’s specific precautions,
such as removing or not removing
vent caps while charging, and
recommended rates of charge.
• Clean the battery terminals. Be care-
ful to keep corrosion from getting in or
around your eyes.
• Be sure that the area around the bat-
tery is well ventilated while it is being
charged. Gas can be forcefully blown
away by using a piece of cardboard or
other nonmetallic material as a fan.
• Wear safety glasses. See additional
“Personal Safety Precautions” on
page 4.
• If it is necessary to remove the battery
from the vehicle to charge it, always
remove the grounded terminal from
the battery first. Turn off all vehicle
accessories to avoid sparks from
occurring.
• For batteries with removable vent
caps, if required, add distilled water to
each cell until the battery acid reach-
es 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 with non-removable
vent caps, no action is necessary.
• NOTE: A marine (boat) battery
installed in a boat must be removed
and charged on shore.

USING THE BUILT-IN BATTERY TESTER
OVERVIEW
TESTING AFTER CHARGING
The SpeedCharge has a built-in battery
tester that displays either an accurate
battery voltage or an estimate of the
battery’s relative charge based on the
battery voltage and the Battery Council
International scale.
After the unit has been changed from
tester to charger (by selecting a charge
rate), it remains a charger as long as it
has power. Disconnect and reconnect
the power to change the unit back to a
tester.
TESTING SEQUENCE
TESTER STATUS LED’s
There are four basic steps required to
use the SC-6000A as a battery tester.
1. Connect the SpeedCharge battery
clamps to the battery. Be sure to follow
all of the precautions listed under
“OPERATING INSTRUCTIONS”.
2. Connect the SpeedCharge power cord
to a 120 VAC outlet. Again, be sure to
follow all of the precautions listed under
“OPERATING INSTRUCTIONS”.
3. If necessary, press the Battery Type
button until the correct type is indi-
cated.
When the SC-6000A is operating as a
battery tester, the status LED’s light
under the following conditions.
• The CHARGED (green) LED will light
if a charged battery is tested.
• The CHARGING (yellow) LED does
not light in the battery test mode.
• The CHECK (red) LED lights unless a
properly connected battery is de-
tected.
• When the tester display mode is set
to voltage, none of the Status LED’s
light (it could be testing a battery or
an alternator).
4. Read the voltage on the digital LED or
press the display mode button to set
the tester to “Battery %” and read the
battery percent.
INITIAL PERCENT CALCULATION
When a battery % is calculated for the
first time after connecting a battery, the
digital LED will show two dashes (“--”)
for a period as long as several seconds
while the tester analyzes the battery.
TESTER AND CHARGER
When first turned on, the SC-6000A
operates only as a tester, not as a
charger. To continue to use it as only a
tester, avoid pressing the CHARGE
RATE switch button. Selecting a charge
rate activates the battery charger and
deactivates the tester.
NOTES FOR TESTING BATTERY %
A recently charged battery could have a
temporarily high voltage due to what is
known as “surface charge”. The voltage
of such a battery will gradually drop
during the period immediately after the
charging system is disengaged.
Consequently, the tester could display
inconsistent values for such a battery.
For a more accurate reading, the
surface charge should be removed by
temporarily creating a load on the
battery, such as by turning on lights or
other accessories.
POWER-UP IDLE TIME LIMIT
If no switch button is pressed within ten
minutes after the unit is first powered
up, the unit will automatically switch
from tester to charger, if a battery is
connected. In that case, the unit will be
set for the 2A charge rate and REGU-
LAR battery type.
TESTER WITHOUT TIME LIMIT
If either the DISPLAY MODE or BAT-
TERY TYPE button is pressed within the
first ten minutes after the unit is
powered up, the unit will remain a tester
(not a charger) indefinitely, unless a
charge rate is selected.
The battery % ranges from 0 to 100.
The battery tester is only designed to
test batteries. Testing a device with a
rapidly changing voltage could yield
unexpected or inaccurate results.
10
USING THE BUILT-IN ALTERNATOR TESTER
The SpeedCharge has a built-in
alternator tester that displays either an
accurate alternator voltage or an
estimate of the alternator’s relative
output compared to normal alternators.
The Alternator % values displayed
should be taken as general reference,
not precise diagnosis. The alternator
tester functions the same as the battery
tester (see previous section of this
on the digital LED or press the
display mode button to set the tester
to “Alternator %” and read the
alternator percent.
TESTER STATUS LED’s
When the SC-6000A is operating as an
alternator tester, the status LED’s light
under the following conditions.
• The CHARGED (green) LED will light
if the output of the charging system is
at the normally desired level.
• The CHARGING (yellow) LED does
not light in the alternator test mode.
• The CHECK (red) LED lights if the
voltage is much higher or lower than
normally desired.
• When the tester display mode is set
to voltage, none of the status LED’s
light (it could be testing a battery or
an alternator).
manual for details) with a few differences.
TESTING SEQUENCE
There are three basic steps required to
use the SC-6000A as an alternator
tester.
1. Connect the SpeedCharge battery
clamps to the battery or charging
system. Be sure to follow all of the
precautions listed under “OPERAT-
ING INSTRUCTIONS”.
2. Connect the SpeedCharge power
cord to a 120 VAC outlet. Again, be
sure to follow all of the precautions
listed under “OPERATING INSTRUC-
TIONS”.
ALTERNATOR TESTING NOTES
• The alternator percent display can
range from 0 to 199.
• The display mode cannot be set to
“Alternator %” during charging.
3. Start the vehicle and turn on the
vehicle’s headlights. Read the voltage

listed under “OPERATING INSTRUC-
TIONS”.
The SC-6000A has an engine start
function that can be used to jump start
your vehicle if the battery is low by
providing 60 amps of current to assist
engine cranking.
3. Press the CHARGE RATE button
until the 60 START indicator is lit.
4. Crank the engine until it starts or 8
seconds passes.
STARTING SEQUENCE
There are a few basic steps involved
when using the engine start function.
5. If the engine did not start, wait for the
SpeedCharge to cool then repeat
step 4.
1. Connect the SpeedCharge battery
clamps to the battery or charging
system. Be sure to follow all of the
precautions listed under “OPERAT-
ING INSTRUCTIONS”.
During the starting sequence listed
above, the charger is set to one of three
states.
1. Wait for cranking - The charger
waits until the engine is actually
being cranked before delivering 60
amps for engine start. The charger
delivers charge at a rate of 10 amps

second. During the cool down period,
the charger delivers charge at a rate
of 10A and the CHARGING LED is
lit. After 2 minutes, the 60A START
LED will stop blinking and will light
continuously, indicating that another
crank cycle can be started. The
digital LED will change from display-
ing the countdown back to displaying
the battery voltage.
2. Cranking - When cranking is
detected, the SpeedCharge will
automatically deliver up to its
maximum output (at least 60A) as
required by the starting system for up
to 8 seconds or until the engine
cranking stops. The digital display
shows a countdown of the remaining
crank time in seconds. It starts at 8
and counts down to 0.
ENGINE STARTING NOTES:
• When the 60A START rate has been
selected, the battery type selected
does not matter and no battery type
LED will be lit.
• If the battery is disconnected during
the cool down period, the charger will
reset.
3. Cool Down - After cranking, the unit
enters a mandatory 2-minute (120
second) cool down state. During this
period, no settings can be changed.
The buttons are ignored. The digital
USING YOUR BATTERY CHARGER
OVERVIEW
ABORTED CHARGE: If charging can’t
be completed normally, charging will be
aborted. When charging is aborted, the
charger’s output is shut off and the red
CHECK LED and digital LED blink on
and off (at opposite times). In that state,
the SpeedCharge ignores all buttons. To
reset from after an aborted charge,
either disconnect the battery or unplug
the charger.
Using the SpeedCharge battery charger
is very simple. First, connect the battery
and AC power following the precautions
listed under “OPERATING INSTRUC-
TIONS”. Then select the appropriate
BATTERY TYPE and CHARGE RATE
for your battery. The SpeedCharge will
then do everything automatically. This
section explains a few details.
CHARGING: If the charger does not
detect a properly connected battery, the
CHECK (red) LED will light continuously
until such a battery is detected. Charg-
ing will not begin while the CHECK light
is on. When charging begins, the
CHARGING LED will be lit.
DESULFATION MODE: If a battery is
left discharged for an extended period, 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 spe-
cial desulfation mode is indicated by
blinking the CHARGING LED. If suc-
cessful, normal charging will resume af-
ter the battery is desulfated. The
CHARGING LED will then stop blinking
and light continuously. Desulfation could
take up to 10 hours. If desulfation fails,
charging will be aborted and the CHECK
(red) LED will blink.
AUTOMATIC SHUT OFF: When the 2A
or 30Aꢀꢁ10A charge rate is selected,
the charger is set to perform an auto-
matic charge. When an automatic
charge is performed, the charger stops
charging automatically after the battery
is charged.
12
30A CHARGE RATE: When set to
30Aꢀꢁ10A, the unit will charge the
battery for a few minutes at 10A. The
charger will determine whether to
increase the current to 30A, based on
factors including the battery voltage and
type selected. If the current is increased
from 10A to 30A, the 30Aꢀꢁ10A LED
will change from yellow to orange.
Eventually, the current will decrease
from 30A back down to 10A and the
LED will change from orange back to
yellow. The charge current may be
increased to 30A and decreased back
down to 10A several times during the
charging process. After the battery has
been charged enough for the display to
indicate 77%, the current will not be
increased to 30A.
MAINTAIN MODE: When the
CHARGED (green) LED is lit, the
charger has started Maintain Mode. This
mode of operation is also known as
Float-Mode Monitoring. In this mode,
the charger keeps the battery fully
charged by delivering a small current,
when necessary. The voltage is main-
tained at a level determined by the
BATTERY TYPE selected.
GENERAL CHARGING NOTES:
The unit is designed to control its
cooling fan for efficient operation.
Consequently, it is normal for the fan to
start and stop when maintaining a fully
charged battery. The fan does not run in
Tester Mode.
If the charge mode is changed after
charging has started (by pressing the
CHARGE RATE or BATTERY TYPE
button), the charging process will be
restarted.
COMPLETION OF CHARGING: Charge
completion is indicated by the
CHARGED (green) LED; when lit, the
charger has stopped charging and
switched to the Maintain Mode of
operation.
The voltage displayed during charging is
the charging voltage and usually will be
higher than the battery’s resting voltage.
CHARGING TIPS
Read this entire manual before using your charger. The tips below serve only as a
guide for specific situations.
If your vehicle won’t start: You don’t
need to fully charge a battery to start
your vehicle. If the charger won’t start
your vehicle using the 60A START rate,
try charging the battery using the
30Aꢀꢁ10A rate for 10 or 15 minutes.
That should charge the battery enough
to allow the 60A START rate to start the
vehicle. If the vehicle will then be
Reviving your battery: If you only wish
to charge your battery enough to
operate your vehicle, you don’t need to
wait for the entire charging process to
be completed. When the charger
displays a battery % of 77 or more (see
page 14), the battery has usually been
charged enough for the vehicle to start
and operate normally.
operated continuously for an extended
period (such as a long drive), the
vehicle could 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.
Completing an interrupted charge: If
the charging process has been inter-
rupted and restarted after the charger
displays a battery % of 85 or more, the
charger could go straight to Maintain
Mode (see top of this page). However, if
the original charge was started using
30Aꢀꢁ10A, the charge can often be
completed using the 2A rate.

BATTERY PERCENT AND CHARGE TIME
This charger adjusts the charging time
There are some important facts to keep
in order to charge the battery com-
pletely, efficiently and safely. The
microprocessor automatically makes
the necessary decisions. However, this
section includes guidelines that can be
used to estimate charging times.
in mind when charging a battery.
• When the display indicates 77%
charged, the battery has been
charged enough to start most vehicles
and has already been charged as
much as by many other battery
chargers.
The duration of the charging process
depends on three factors:
• When the display indicates 85%
charged, the battery has already been
charged at least as much as by most
other battery chargers.
1. 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 using the built-in
tester (see page 10). The lower the
reading the longer charging will take.
• The battery % shown in tester mode
is an estimate based on the battery
voltage and the Battery Council
International scale. The battery %
shown in charger mode is an estimate
of the relative charge in the battery
compared to the charge it should
have if the charging process is
allowed to complete.
2. 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

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. This will help
prevent accidental damage to the cords and charger.
3. Occasional cleaning of the case of the charger with a soft cloth will keep the finish
shiny and help prevent corrosion.
