TROUBLESHOOTING
Fault LED Lit
The following conditions may light the FAULT LED:
• Poor connection to battery (or frame).
• Charging too fast — decrease charge rate by pressing the Charge Rate Selector
2A/4A/6A 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.
Try charging another battery, if the FAULT LED does not light, then one of the above
problems exists with the initial battery. Charger will not charge and the fan will not
operate if there is a fault. Call Technical Support toll free: (800) 618-5178.
Reverse Polarity LED Lit
• Incorrect polarity — follow the steps outlined in “Important Safety Instructions” at
the front of this manual.
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
slow. The rate of charge will increase as the battery warms. NEVER attempt to charge
a frozen battery.

APPROXIMATE 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.

*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 Ah 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 time.
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 clamps.
• Clean the outside case of the charger with a soft cloth and, if necessary, mild soap
solution.
• 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
cords.
WARNINGS
• Do not use charger if cords or clamps have been damaged in any
way — call Technical Support toll-free at (800) 618-5178.
• 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 WARRANTY.
