TROUBLESHOOTING
• FOR 12V BATTERIES
If you are trying to charge a 12V battery that is below 7.0VDC, you
will need to select the 13.6V SUPPLY mode. The 13.6V SUPPLY
mode is for 12V batteries ONLY. In this mode, the battery charger
does not use battery voltage as a restriction to begin applying current.
Before selecting the 13.6V SUPPLY mode, make sure you understand how
to use this charge mode by reading “USING 13.6V SUPPLY MODE.”

CHARGE LEDs IMMEDIATELY ILLUMINATE TO 100%
If the battery charger’s CHARGE LEDs 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” sound you hear
does not signify a battery charger failure. The “clicking” sound 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 7.0VDC (12V) or 14.0VDC (24V), 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:
TROUBLESHOOTING
As a standard matter of practice, allow the battery charger to charge
the battery in this mode for at least sixty (60) minutes. After the
elapsed time, the battery voltage should be above 7.0VDC. Press
the MODE button one (1) time to exit the 13.6V SUPPLY mode and
return the battery charger to STANDBY mode. Return the battery
charger back to the appropriate 12V charge mode, depending on
the chemistry of your battery, to begin the charge cycle.
• FOR 24V BATTERIES
If you are trying to charge a 24V battery that is below 14.0VDC you
will need to select the 13.6V SUPPLY mode. The 13.6V SUPPLY
mode is for 12V batteries ONLY. If your battery system is comprised
of two (2) 12V batteries in series, you can follow the instructions given above
in the ‘For 12V Batteries’ section and charge each individual 12V battery
independently until the combined battery voltage exceeds 14.0VDC. Return
the battery charger back to the appropriate 24V charge mode, depending on
the chemistry of your battery, to begin the charge cycle. IF YOUR 24V
BATTERY SYSTEM IS COMPRISED OF SOMETHING OTHER THAN TWO (2)
12V BATTERIES, THEN YOU WILL NEED TO JUMP START THE BATTERY.
WICKED SMART TIP
If you have a severely discharged battery, a battery that is below
9.0VDC (12V) or 18.0VDC (24V), 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.
