RATE SELECTION
Press this button until the desired charge
rate is selected.
• 3A MAINTAIN – Used to keep stored
lead-acid batteries charged. Charges and
maintains small batteries. Maintains large
batteries that are already fully charged.
• 5A CHARGE – For charging small batteries,
such as those commonly used in garden
tractors, snowmobiles and motorcycles.
Also used to completely charge deep-cycle
batteries.
• 20 A or 30A FAST CHARGE – For charging
automotive, marine and light truck batteries.
Not intended for industrial applications.
• 75 A or 100A ENGINE START – Provides
high amperage for cranking an engine with
a weak or run-down battery. Always use in
combination with a battery.
NOTE: Once the charger has started
charging the battery; if you press the Rate
Selection button once, the output current is
shut off and the display will show OFF, and
then the battery voltage. If you press the
Rate Selection button again, the current will
go back on at the same setting it was when
it was turned off.
LED INDICATORS
CONNECTED (red) LED lit: The
charger is properly connected to the battery
CHARGING (yellow/orange) LED lit:
The charger has detected a battery and is
charging it.
CHARGING (yellow/orange) LED
flashing: The charger is in abort mode.
CHARGED (green) LED lit: The
battery is fully charged and the charger is in
maintain mode.
11. OPERATING INSTRUCTIONS
WARNING: A spark near battery may cause
a battery explosion.
IMPORTANT: Do not start the vehicle with
the charger connected to the AC outlet, or it
could result in damage to the charger
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. Place the charger on a dry, non-
flammable surface.
5. Lay the AC/DC cables away from any
fan blades, belts, pulleys and other
moving parts.
6. Connect the battery, following the
precautions listed in sections 6 and 7.
NOTE: See the Operating Instructions
section for a complete description of the
charger modes.
BATTERY TYPE BUTTON
Use this button to set the type of battery
to charge.
– 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.
Regular batteries should not be used for
deep-cycle applications.
– 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.
– 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.
7. Connect the charger to an electrical outlet.
8. Select the battery type and charge rate.
9. When charging is complete, disconnect
the charger from the AC power, remove
the clamps from the vehicle's 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. Connect the battery, following the
precautions listed in sections 6 and 7.
4. Connect the charger to the electrical outlet.
5. Select the battery type and charge rate.
