Fault LED Lit
The following conditions may light the FA U LT L E D :
• Poor connection to battery (or frame).
• Charging too fast — decrease charge rate by pressing the Charge Rate Selector
2 A / 4 A / 6 A button to select a lower rate.
• Charging too slowly - battery is large and did not complete charging in 24 hours.
Press the Charge Rate Selector 2A/4A/6A button to select a faster rate.
• Shorted battery cell — check battery.
• Open battery cell — check battery.
• Internal shorted battery cell — take your battery to a certified automotive service
center for evaluation.
• Internal overheat in charger — make sure fan is not blocked.

Battery Not Accepting a Charge
•
Make sure that
the charger is plugged into
a “live” 110/120 volt AC outlet
and
Power LED is lit.
• Unplug the
charger
and check
battery connections
-
ensure that
there is a good
connection
at the battery
terminal and/or
vehicle chassis.
• Check that
the correct charge
rate was selected
for
the battery being
charged.
• Ensure
enough charging time was allowed to charge
battery.
Charging a Very Cold Battery
If
the battery to be charged is
extremely
cold (in temperatures
below freezing
—
0ºC/32ºF),
it
cannot accept a high rate of charge, so the
initial charge rate will
be
s l o w. The rate of
charge will increase as the battery warms.
N E V E R attempt
to
charge a frozen
battery.

Input: 120 volts AC, 110 watts
Output: 12 volts DC, 2/4/6 amps
A P P R O X I M ATE CHARGING TIMES
The 2/4/6 Amp 12 Volt Smart Battery Charger will automatically adjust the charge
rate as the battery becomes charged and stop when the battery is fully charged.
Deep cycle batteries may require longer charging time.
For estimates of the time it takes to charge a battery, refer to the following table.
Percent of charge
in battery 7 5 % 5 0 % 2 5 % 0 %
at 2 amp rate 7 HRS 14 HRS NR* N R *
at 4 amp rate 3.5 HRS 7 HRS 10.5 HRS 14 HRS
at 6 amp rate 2.5 HRS 4.7 HRS 7 HRS 9.2 HRS
*NR = Not recommended at 2 amps — use a higher charge rate.
The times shown in the table above are approximate and refer to a 50 A h
automotive battery. For example, a 50 Ah (12 volt) battery is discharged (50%). How
long should it be charged at the 6 amp rate? See the chart above under “50%” and
“at 6 amp rate.”
In most cases, battery charging times will vary depending on the size, age and
condition of the battery. Smaller batteries should be charged at a lower rate
( 2 amps) and an extra hour added to charge tim
e.
CARE AND MAINTENANCE
With proper care and minimal maintenance, the
6 Amp / 4 Amp / 2 Amp Smart
Battery Charger
will provide years of dependable service. For maximum
performance, manufacturer recommends:
• After each use, clean the battery charger clamps — be sure to remove any battery
fluid that will cause corrosion of the copper clamps.
• Clean the outside case of the charger with a soft cloth and, if necessary, mild soap
s o l u t i o n .
• Do not allow liquid to enter the charger. Do not operate when charger is wet.
• Keep the charger cords loosely coiled during storage to prevent damage to the
c o r d s .
WA R N I N G S
• There are no user-serviceable parts in this unit.
• Do not open the unit.
In the event
of malfunction,
it
must
be returned to
manufacturer for professional testing and repair. OPENING THE UNIT WILL
VOID THE
MANUFACTURER’S WA R R A N T Y.
