• Cold Batteries – Start charging at a
low rate of charge and as the battery
warms up while charging, the charging
rate will increase. After this happens, the
battery will charge up and the meter will
decrease normally.
• Shorted Batteries (battery has shorted
circuit in one or more cells) – The meter
will usually “peg” at the high amp end of
the scale. If after 5-10 minutes of charging
and the needle has not started to move
down scale, stop charging and have the
battery checked. One way to check the
battery, would be to measure the voltage
at the battery terminals. If the voltage is
below 12 volts on a 12 volt battery, (under
6 on a 6 volt battery), plug the charger
back in and resume charging for about 15
more minutes. If the meter has failed to
move towards a lower scale reading, the
battery needs to be serviced or replaced.
• Lead-Calcium batteries – When this
type battery is deeply discharged, it may
require an activation period before it will
accept a measurable charge. (This may
take as much as 6 hours before normal
charging begins). You should suspect
this condition if the meter indicates at or
near zero, but you have determined the
battery is very deeply discharged. Simply
continue to charge the battery until the
battery becomes activated(keep an eye
on the charge every 20 minutes or so) you
will see the meter indicating a higher rate
of charge. This will be when the recharge
of the battery commences. The battery is
charged when the meter indicates about
1/2 of the selected charge rate (about 4-5
amps on the 10 amp setting, and about
10-15 amps on the 30 amp setting).
This charger is also equipped with a
Dual self reset Circuit Breaker System.
The rst breaker is designed to interrupt
a high ow of current normally developed
while cranking the engine. This is the same
breaker that will open when the output
leads are accidentally shorted together
or connected to a battery in reverse. The
second breaker will open if prolonged
cranking persists or for any other condition
in which the output current is much greater
than the 30 amp continuous rating.
11. OPERATING INSTRUCTIONS
WARNING: A spark near the battery may
cause an explosion.
CHARGING A BATTERY
IN THE VEHICLE
1. Turn off all the vehicle’s accessories.
2. Keep the hood open.
3. Clean the battery terminals.
4. Set the volt/amp selector switch to the
OFF position.
5. Lay the AC/DC cables away from any
fan blades, belts, pulleys and other
moving parts that can cause injury.
6. Connect the battery, following the
precautions listed in sections 6 and 7.
7. Connect the charger to an electrical
outlet.
8. Select the desired charge rate.
9. MONITOR THE CHARGER AND
THE BATTERY.
10. When disconnecting the charger, set
the volt/amp selector switch to the OFF
position, disconnect the charger from
the AC power, remove the clamp from
the vehicle chassis, and then remove
the clamp from the battery terminal.
CHARGING A BATTERY
OUTSIDE OF THE VEHICLE
1. Place battery in a well-ventilated area.
2. Clean the battery terminals.
3. Set the volt/amp selector switch to the
OFF position.
4. Connect the battery, following the
precautions listed in sections 6 and 7.
5. Connect the charger to the electrical
outlet.
6. Select the desired charge rate.
7. MONITOR THE CHARGER AND
THE BATTERY.
8. When disconnecting the charger, set
the volt/amp selector switch to the OFF
position, disconnect the charger from
the AC power, disconnect the negative
clamp, and nally the positive clamp.
9. A marine (boat) battery must be
removed and charged on shore.
MANUAL CHARGING MODE
When manual mode is performed, the
charger will continue to charge and will not
shut off. Monitor the charging process and
stop when the battery is fully charged. Not
doing so may damage your battery and
result in property damage or personal injury.
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.
