12. CALCULATING CHARGE TIME

Use the following table to more accurately
determine the time it will take to bring a
battery to full charge.
CCA = Cold Cranking Amps
RC = Reserve Capacity
Ah = Amp Hour
NR = Not Recommended
MO = Maintain Only
BATTERY SIZE/RATING

13. MAINTENANCE AND CARE

A minimal amount of care can keep your
battery charger working properly for years.
• Clean the clamps each time you are
finished charging. Wipe off any battery
fluid that may have come in contact with
the clamps to prevent corrosion.
• Occasionally cleaning the case of the
charger with a soft cloth will keep the
finish shiny and help prevent corrosion.

14. TROUBLESHOOTING/ERROR CODES

Error Codes
ERROR CODE
The battery voltage is still
under 10V (for a 12V battery)
F01
or 5V (for a 6V battery) after
2 hours of charging.
The charger cannot desulfate
F02
the battery.
The battery was unable to
reach the "full charge" voltage.
F03
The connections to the battery
F04
are reversed.
The charger was unable to
keep the battery fully charged
F05
in maintain mode.
The charger detected that the
F06
battery may be getting too hot
(thermal runaway).
If you get an error code, check the connections and settings and/or replace the battery.

DESCRIPTION
Find your battery's rating on the chart
below, and note the charge time given
for each charger setting. The times given
are for batteries with a 50% charge prior
to recharging. Add more time for severely
discharged batteries.

• Coil the input and output cords neatly
when storing the charger. This will help
prevent accidental damage to the cords
and charger.
• Store the charger unplugged from the AC
power outlet, in an upright position.
• Store inside, in a cool, dry place. Do not
store the clamps clipped together, clipped
to the handle, on or around metal, or
clipped to the cables.
The battery could be bad. Have it checked or
replaced.
The battery could not be desulfated; have it
checked or replaced.
May be caused by trying to charge a large battery
or bank of batteries on too low of a current setting.
Try again with a higher current setting or have the
battery checked or replaced.
The battery is connected backwards. Unplug the
charger and reverse the connections to the battery.
The battery won't hold a charge. May be caused
by a drain on the battery or the battery could be
bad. Make sure there are no loads on the battery.
If there are remove them. If there are none, have
the battery checked or replaced.
The charger automatically shuts the current off if
it detects the battery may be getting too hot. Have
the battery checked or replaced.
