DESULFATION MODE
Desulfation could take 8 to 10 hours. If
desulfation fails, charging will abort and
the Bad Battery (red) LED will light.
COMPLETION OF CHARGE
Charge completion is indicated by the
Charged/Maintaining (green) LED.
When lit, the charger has switched to the
maintain mode of operation.
MAINTAIN MODE
(FLOAT MODE MONITORING)
When the Charged/Maintaining (green)
LED is lit, 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 an excessive 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.
MAINTAINING A BATTERY
This unit charges and maintains 12V
batteries, keeping them at full charge.
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 ENGINE START FEATURE
Your battery charger can be used to jump
start your car if the battery is low. Follow
all safety instructions and precautions for
charging your battery. Wear complete eye
protection and protective clothing.
WARNING: Using the Engine Start feature
WITHOUT a battery installed in the vehicle
could cause damage to the vehicle’s
electrical system.
NOTE: If you have charged the battery and
it still will not start your car, do not use the
Engine Start feature, or it could damage
the vehicle’s electrical system. Have the
battery checked.
1. With the charger unplugged from the
AC outlet, connect the charger to the
battery following the instructions given
in Follow These Steps When Battery
is Installed in Vehicle.
2. Connect the charger to a live grounded
120V AC outlet.
3. With the charger plugged in and
connected to the battery and chassis,
press the Rate Selection button until
the Engine Start LED is lit, and then
press the START button.
4. Crank the engine until it starts or 7
seconds pass. If the engine does not
start, repeat. Do not crank during the
cool down period (see below). This
allows the charger and battery to cool
down. NOTE: During extremely cold
weather, or if the battery is under 2
volts, charge the battery for 5 minutes
before cranking the engine.
5. If the engine fails to start, charge the
battery for 5 more minutes before
attempting to crank the engine again.
6. After the engine starts, unplug the AC
power cord before disconnecting the
battery clamps from the vehicle.
7. Clean and store the charger in a dry
location.
NOTE: If the engine does turn over but
never starts, there is not a problem with
the starting system; there is a problem
somewhere else with the vehicle. STOP
cranking the engine until the other problem
has been diagnosed and corrected.
ENGINE STARTING NOTES
During the starting sequence listed above,
the charger is set to one of four states:
• Wait for ready – The charger charges
the battery for 2 minutes before the Wait
for Cranking state. While waiting for
ready, the engine can be cranked. For
severely discharged batteries, it is not
recommended to crank during this time.
• Wait for cranking – The charger waits
until the engine is actually being cranked
before delivering the amps for engine start.
• Cranking – When cranking is detected,
the charger will automatically deliver up
to its maximum output as required by the
starting system for up to 7 seconds.
• Cool Down – After repeated cranking
during a 3-minute ready period, the
charger enters a mandatory 3 minute (180
second) cool down state. After 2 hours of
Engine Starting, the unit will automatically
exit from the charging mode, just as if the
STOP button had been pressed; the ON
LED will not be lit.
