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.

BEFORE USING YOUR BATTERY CHARGER  
It is important to understand the charger’s requirements. This section explains the  
charger’s electrical requirements and how to prepare a battery for charging.  
extension cord, please make sure that  
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  
TESTINGAFTERCHARGING  
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  
TESTERSTATUSLEDs  
There are four basic steps required to  
use the 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 6000A is operating as a  
battery tester, the status LEDs 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 LEDs  
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 6000A oper-  
ates 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.

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

• 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 LEDs  
light (it could be testing a battery or  
an alternator).  
TESTING SEQUENCE  
There are three basic steps required to  
use the 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  
on the digital LED or press the

TIONS”.  
The 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.  
STARTINGSEQUENCE  
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  
2. Connect the SpeedCharge power

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 30A10A 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  
30A10A, 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 30A10A 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  
30A10A 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  
30A10A, 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  
(RC) and cold cranking amps (CCA).  
The lower the rating the quicker the  
battery will be charged.  
• The battery % shown in tester mode  
can be used to estimate the relative  
charge time. The lower the % shown,  
the longer the charge time. The lower  
the % shown, the longer the charge  
time for a given battery.  
3. Charge rate – The charge rate is  
measured in amps. This charger  
provides charge rates of 2A and  
30A10A. The 60A rate is for

is an indication of the relative  
progress of the charging process. The  
higher the battery % displayed, the

engine start only. The 2A rate is for  
charging smaller batteries such as  
those used for motorcycles and  
garden tractors. Such batteries  
should not be charged using the  
30A10A rate. The 30A10A rate  
is for charging larger batteries. The  
6000A charges at the selected  
charge rate and eventually reduces  
the charge rate in a controlled  
• The more a battery is discharged, the  
faster it absorbs charge from a  
charger. That means that the battery  
% 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 percent  
of charge than the first several  
percent.  
manner. After the charging process  
has started, the digital display can be  
used to determine charging progress  
by selecting the BATTERY % mode.

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.
