MAINTAIN MODE
(FLOAT MODE MONITORING)
When the FULL CHARGE (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 battery
voltage drops below a preset level, the
charger will go back into charge mode
until the battery voltage returns to the full
charge level, at which point the charger
will return to maintain mode. The voltage
is maintained at a level determined by the
battery type selected.
MAINTAINING A BATTERY
An automatic charger charges and
maintains 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 SETTING
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 clothing protection.
WARNING: Using the ENGINE START
setting WITHOUT a battery installed in

12. CALCULATING CHARGE TIME

Use the following table to more accurately
determine the time it will take to bring a
battery to full charge. First, identify where
your battery fits into the chart.

RC = Reserve Capacity
Ah = Amp Hour
NR = Not Recommended

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 setting, 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 the CHARGING A BATTERY IN
THE VEHICLE section.
2. With the charger plugged in and
connected to the battery of the vehicle,
set the charge rate to the Engine Start
position.
3. Crank the engine until it starts or 5
seconds pass. If the engine does not
start, wait 3 minutes before cranking
again. NOTE: During extremely cold
weather, or if the battery is under 2
volts, charge the battery for 5 minutes
before cranking the engine.
4. If the engine fails to start, charge the
battery for 5 more minutes before
attempting to crank the engine again.
5. After the engine starts, unplug the AC
power cord before disconnecting the
battery clamps from the vehicle.
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.
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.
