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 polarity of battery posts. POSITIVE
(POS, P, +) battery post usually has a larger
diameter than NEGATIVE (NEG, N, –) post.
7.2 Attach at least a 24-inch-long 6-gauge
(AWG) insulated battery cable to
NEGATIVE (NEG, N, –) battery post.
7.3 Connect POSITIVE (RED) charger clip to
POSITIVE (POS, P, +) post of battery.
7.4 Position yourself and free end of cable as
far away from battery as possible – then

8. GROUNDING AND AC POWER CORD CONNECTIONS

This battery charger is for use on a
nominal 120 volt circuit. 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 fit the receptacle (outlet). Do
not use with an ungrounded system.
DANGER: Never alter the AC cord or
plug provided – if it does not fit the outlet,
have a proper grounded outlet installed
by a qualified electrician. An improper
connection can result in a risk of an
electric shock or electrocution.
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.

9. ASSEMBLY INSTRUCTIONS

9.1 Remove all cord wraps and uncoil the cables prior to using the battery charger.

10. CONTROL PANEL

DIGITAL DISPLAY
The digital display indicates the status of
the battery and charger. See the Display
Messages section for a complete list of
messages.
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.
connect NEGATIVE (BLACK) charger clip
to free end of cable.
7.5 Do not face battery when making final
connection.
7.6 When disconnecting charger, always do
so in reverse sequence of connecting
procedure and break first connection
while as far away from battery as
practical.
7.7 A marine (boat) battery must be removed
and charged on shore. To charge it on
board requires equipment specially
designed for marine use.
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
specified:
Length of cord (feet)
AWG* size of cord
*AWG-American Wire Gauge
• Alternator % – 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 LOW and readings above 100%
(14.6 volts) will read HI . GH. If you get a
HI . GH or LOW reading, have the electrical
system checked by a qualified technician.
• Voltage – The Digital Display shows the
voltage at the charger battery clamps,
in DC volts, prior to charging. During
charging, it shows the auto-detected
battery charge voltage.
