PLUGGING IT IN
Your charger requires a 120V AC
receptacle installed according to all local
codes and ordinances.
extension cord, please make sure that
you follow these guidelines:
• 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.
MINIMUM RECOMMENDED EXTENSION CORD
USING AN EXTENSION CORD
The use of an extension cord is not
recommended. If you must use an
Length of Cord, in Feet 25 50 100 150
AWG* Size of Cord 18 16 12 10
*AWG=American Wire Gauge
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 or
6 volt lead-acid battery. Determine
voltage of battery by referring to
vehicle owner’s manual or the battery
markings. Be sure to set the charger
to the 6V or 12V mode accordingly.
Charge battery initially at charger’s
lowest rate.
• Clean the battery terminals. Be
careful to keep corrosion from getting
in or around your eyes.
• Wear safety glasses. See additional
“Personal Safety Precautions” on
page 4.
• If required, for batteries with removable vent caps, add distilled water to
each cell until the battery acid
reaches 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.
• 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.
• Be sure that the area around the
battery 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.
• 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.
• NOTE: A marine (boat) battery
installed in a boat must be removed
and charged on shore.

USING THE BUILT-IN BATTERY TESTER
OVERVIEW
This battery charger 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.
TESTING SEQUENCE
There are four basic steps required to
use the 10000A as a battery tester.
1. Connect the charger battery clamps to
the battery. Be sure to follow all of the
precautions listed under “OPERATING
INSTRUCTIONS”.
2. Connect the charger 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 indicated.
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.
TESTER AND CHARGER
When first turned on, the 10000A
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.
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 12V
REGULAR battery type.
TESTER WITHOUT TIME LIMIT
If either the DISPLAY MODE or BATTERY 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.
TESTING AFTER CHARGING
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.
TESTER STATUS LEDs
When the 10000A 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 detected.
• When the tester display mode is set
to voltage, none of the Status LEDs
light.
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.
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.
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.
