TROUBLESHOOTING
• FOR 6V BATTERIES
If you are trying to charge a 6V battery that is below 2.0VDC, you will need to
jump start the battery or connect the battery to a power supply to increase
the battery voltage above 2.0VDC to begin the charge cycle.

CHARGE LED(S) IMMEDIATELY ILLUMINATE TO 100%
If the battery charger’s CHARGE LED(S) immediately illuminate to 100%
when the AC power is applied to the battery charger, the battery is either
already fully charged or the battery is in extremely poor condition as a result
of sulfation or damage. If the battery is new, the battery is likely already fully
charged. If the battery is relatively old and has not been used for a long
period of time, the battery is probably so severely damaged that the battery
cannot accept any current.
BATTERY CHARGER MAKING A CLICKING SOUND
If the battery charger is making a “clicking” sound and will not go into
a charge mode, it is probably the result of a battery in extremely poor
condition as a result of sulfation or damage. The “clicking” noise you hear
does not signify a battery charger failure. The “clicking” noise is the battery
charger attempting to enter into a charge mode, but when current is applied
to the battery, the battery voltage rises too quickly, and the battery charger
shuts off. Once the current is removed from the battery, the battery voltage
rapidly decreases, and the battery charger again tries to enter into a charge
mode. The “clicking” sound and this ERROR loop condition will continue
until the poor battery is removed.
LOW VOLTAGE BATTERY
If the battery voltage is below 2.0VDC (6V) or 7.0VDC (12V), the ERROR LED
(Orange) and the CHARGE LEDs (25%, 50%, 75%, and 100%) will blink,
indicating the battery is out of range for the battery charger. In this situation,
the battery charger has determined that the battery voltage is too low to
begin a normal charge mode. In order to increase the battery voltage to
allow the battery charger to begin charging, follow these steps:

• FOR 12V BATTERIES (1.2-14Ah)
If you are trying to charge a 12V battery that is below 7.0VDC, switch the
battery charger into 6V mode to begin charging a low voltage 12V battery.
Choose either 6V SMALL NORM mode for Wet Cell, MF, or Gel Cell batteries
or 6V SMALL COLD/AGM mode for AGM batteries. When the 100%
CHARGE LED turns to a solid (not blinking) Green, the battery voltage
will be above 7.0VDC and you can return the battery charger back to the
appropriate 12V SMALL charge mode, depending on the chemistry of your
battery, to begin the charge cycle.
• FOR 12V BATTERIES (14-120Ah)
If you are trying to charge a 12V battery that is below 7.0VDC, switch the
battery charger into 6V mode to begin charging a low voltage 12V battery.
Depending on the chemistry of your battery, choose 6V NORM mode for Wet
Cell or Gel Cell batteries or 6V COLD/AGM mode for AGM batteries. When
the 100% CHARGE LED turns to a solid (not blinking) Green, the battery
voltage will be above 7.0VDC and you can return the battery charger back
to the appropriate 12V charge mode, depending on the chemistry of your
battery, to begin the charge cycle.
WICKED SMART TIP
If you have a severely discharged battery, a battery that is below
4.5VDC (6V) or 9.0VDC (12V), it could be the result of a defective
battery. Batteries that have been severely discharged as a result of an
accidental load should respond quickly when current is applied to the
battery, resulting in a sharp increase in battery voltage.
Now That’s Smart, Wicked Smart.™
TESTING TO SEE IF CHARGER IS CHARGING
Before applying AC power to the charger, measure the battery with a digital
volt meter and write the value down. Then plug the charger in making sure
that within 5 seconds the charger is indicating that the charging process has
begun (See WICKED SMART FEATURE: INITIALIZATION). Wait 30 seconds
and measure the battery again with the digital volt meter. The battery voltage
should be higher and slowly moving up.
