NOTE:
During charging, the display will
go into sleep mode and will not show the
percentage of charge or voltage of the
battery. To turn the display back on, press
the Display button.
DISPLAY BUTTON
Use this button to set the function of the
digital display to one of the following:
• Battery % –
The digital display shows
an estimated charge percentage of
the battery connected to the charger’s
battery clamps, when charging.
• Alternator % (12V only) –
The digital
display shows an estimated output
percentage of the vehicle’s charging
system connected to the charger’s
battery clamps, compared to a properly
functioning system. The alternator percent
range is from 0% to 100%. Readings
below 0% (13.2 volts) will read
LO
and
readings above 100% (14.6 volts) will
read
HI
. If you get a
HI
or
LO
reading,
have the electrical system checked by a
qualified technician.
• Voltage –
The Digital Display shows the
voltage at the charger battery clamps, in
DC volts.
RATE SELECTION BUTTON
Use this button to select one of the
following:
• 6<>2A CHARGE/MAINTAIN –
For
charging small and large batteries. Not
recommended for industrial applications.
• 50A BOOST –
This setting should only
be used to provide a quick boost to a
severely discharged battery, prior to
using the Engine Start function. Do not
use this setting to charge your battery.
• 250A ENGINE START –
Provides 250
amps for cranking an engine with a
weak or run-down battery. Always use in
combination with a battery.
LED INDICATORS
CLAMPS REVERSED (red) LED
flashing:
The connections are reversed.
CHARGING (yellow/orange) LED lit:
The charger is charging the battery.
CHARGING (yellow/orange) LED
flashing:
The charger is in abort mode.
CHARGED/MAINTAINING (green) LED
pulsing:
The battery is fully charged and
the charger is in maintain mode.
NOTE:
See the Operating Instructions
section for a complete description of the
charger modes.
BATTERY TYPE BUTTON
Use this button to select the type of battery.
• STANDARD
– Used in cars, trucks and
motorcycles, these batteries have vent caps
and are often marked “low maintenance” or
“maintenance-free”. This type of battery is
designed to deliver quick bursts of energy
(such as starting engines) and has a
greater plate count. The plates are thinner
and have somewhat different material
composition. Standard batteries should not
be used for deep-cycle applications.
• AGM
– The Absorbed Glass Mat
construction allows the electrolyte to
be suspended in close proximity with
the plate’s active material. In theory,
this enhances both the discharge and
recharge efficiency. The AGM batteries
are a variant of Sealed VRLA (valve
regulated lead-acid) batteries. Popular
uses include high-performance engine
starting, power sports, deep-cycle, solar
and storage batteries.
• GEL –
The electrolyte in a GEL cell has
a silica additive that causes it to set up or
stiffen. The recharge voltages on this type of
cell are lower than those for other styles of
lead-acid battery. This is probably the most
sensitive cell in terms of adverse reactions
to overvoltage charging. Gel batteries are
best used in VERY DEEP cycle application
and may last a bit longer in hot weather
applications. If the wrong battery charger is
used on a gel cell battery, poor performance
and premature failure will result.
11. OPERATING INSTRUCTIONS
WARNING:
A spark near the battery may
a cause battery 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 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.
