result in a re, electric shock or injury.
• Locate the battery charger’s power cord so
it cannot be stepped on, tripped over, or
subjected to damage or stress.
• Do not operate the charger if it has received
a sharp blow, been dropped, or otherwise
damaged in any way. Take it to a qualied
professional for inspection and repair.
• Do not disassemble the charger. Take it to a
qualied professional when service or repair
is required.

GROUNDING AND AC POWER CORD CONNECTIONS
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.
NOTE: Pursuant to Canadian Regulations,
use of an adapter plug is not allowed in
Canada. Use of an adapter plug in the
United States is not recommended and
should not be used.
USING AN EXTENSION CORD
The use of an extension cord is not
recommended. If you must use an
extension cord, follow these guidelines:
• Pins on plug of extension cord must be the
same number, size, and shape as those of
plug on charger.
• Ensure that the extension cord is properly
wired and in good electrical condition.
• Wire size must be large enough for the AC
ampere rating of charger, as specied below:

FEATURES/CONTROL PANEL
DIGITAL DISPLAY
The Digital Display gives a digital indication of
voltage, % of charge or time. The display will
show the battery VOLTAGE when the charger
is not charging a battery. When it goes into
charging mode, the display will automatically
change to ON (to show charging has started)
and either 6 or 12 (the voltage of the battery,
determined by the charger). If you manually
stop the charging process (by pressing the
Rate Selection button) before the battery is
fully charged, the display will show Off.
NOTE: During charging, the display will go
into sleep mode and will not show the
percentage of charge or voltage of the
battery. To turn the display back on, press
the Display button.
DISPLAY MODE BUTTON
Use this button to set the function of the
digital display to one of the following:
• Battery % – The digital display shows an
estimated charge percentage of the battery
connected to the charger’s battery clamps,
when charging.
• Alternator % (12V only) – The digital display
shows an estimated output percentage of the
vehicle’s charging system connected to the
charger’s battery clamps, compared to a
properly functioning system. The alternator
percent range is from 0% to 100%. Readings
below 0% (13.2 volts) will read LO and readings
above 100% (14.6 volts) will read HI. If you get
a HI or LO reading, have the electrical system
checked by a qualied technician.
• Voltage – The Digital Display shows the
voltage at the charger battery clamps, in
DC volts.
RATE SELECTION
Use this button to select one of the following:
• 6<>2A CHARGE/MAINTAIN – For charging
small and large batteries. Not recommended
for industrial applications.
• 30<>12A BOOST – This setting may be
used for a quick boost, prior to using the
engine start setting. Do not use this setting
to charge your battery.
• 80A ENGINE START – Provides additional
amps for cranking an engine with a weak or
run-down battery. Always use in combination
with a battery.
NOTE: Once the charger has started charging
the battery, if you press the Rate Selection
button once, the output current is shut off and
the display with show OFF and then the battery
voltage. If you press the Rate Selection button
again, the current will go back on at the same
setting it was when it was turned off.

BATTERY TYPE BUTTON
This selects the type of battery to charge.
• Standard – Used in cars, trucks and
motorcycles, these batteries have vent caps
and are often marked “low maintenance” or
“maintenance-free”. This type of battery is
designed to deliver quick bursts of energy
(such as starting engines) and has a greater
plate count. The plates are thinner and have
somewhat different material composition.
Regular batteries should not be used for
deep-cycle applications.
• AGM – The Absorbed Glass Mat
construction allows the electrolyte to be
suspended in close proximity with the
plate’s active material. In theory, this
enhances both the discharge and recharge
efciency. The AGM batteries are a variant
of Sealed VRLA (valve regulated lead-acid)
batteries. Popular uses include highperformance engine starting, power sports,
deep-cycle, solar and storage batteries.
• Gel – The electrolyte in a GEL cell has a
silica additive that causes it to set up or
stiffen. The recharge voltages on this type of
cell are lower than those for other styles of
lead-acid battery. This is probably the most
sensitive cell in terms of adverse reactions to
overvoltage charging. Gel batteries are best
used in VERY DEEP cycle application and
may last a bit longer in hot weather
applications. If the wrong battery charger is
used on a gel cell battery, poor performance
and premature failure will result.
