DESULFATION MODE
Desulfation could take 8 to 10 hours. If
desulfation fails, charging will abort and the
CHARGING (yellow) LED will flash.
COMPLETION OF CHARGE
Charge completion is indicated by the
FULL
(green)
LED. When pulsing, the charger has
switched to the maintain mode of operation.
MAINTAIN MODE
(FLOAT-MODE MONITORING)
When the FULL
(green) LED is pulsing, the charger has
started maintain mode. In this mode, the
charger keeps the battery fully charged by
delivering a small current when necessary.
If the charger has to provide its maximum
maintain current for a continuous 12 hour
period, it will go into abort mode (see
Aborted Charge section). This is usually
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.
MAINTAINING A BATTERY
The KTB-BC1801 charge and maintain
both6 and 12volt batteries.
The KTB-BC1806 charge and maintain
both6,12 and 24volt batteries.
NOTE: The maintain mode technology
allows you to safely charge and maintain a
healthy battery for extended periods of time.
However, problems with the battery, electrical
problems in the vehicle, improper
connections or other unanticipated conditions
could cause excessive current draws. As
such, occasionally monitoring your battery
and the charging process is required.
USING THE BATTERY VOLTAGE TESTER
1.
With the charger unplugged from the
AC outlet, connect the charger to the
battery following the instructions given in
previous sections.
2.
Plug the charger AC power cord into the
AC outlet.
3.
If necessary, press the SWITCH button
until the correct type is indicated.
4.
Read the voltage on the digital display.
Keep in mind that this reading is only a
battery voltage reading; a false surface
charge may mislead you. Compare the
reading to the chart below.

POWER-UP IDLE TIME LIMIT
If no button is pressed within 5 minutes
after the battery charger is first powered up,
the charger will automatically switch from
tester to charger if a battery is connected.
In that case, the charger will be set to charge
at the 2A rate
TESTING AFTER CHARGING
After the unit has been changed from tester
to charger (by selecting a charge rate), it
remains a charger. To change the battery
charger back to a tester, press the
SWITCH button until all charge rate LEDs
are off.
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.
• 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, on or
around metal, or clipped to the cables.
