OPERATING INSTRUCTIONS

12.

Automatic Voltage Detection

When the charger is connected to a battery, it will automatically determine

whether the connected battery is a 6 Volt battery or a 12 Volt battery. This

eliminates the possibility of using the wrong voltage setting.
Automatic Temperature Compensation

The charger adjusts the maximum charge voltage and maximum maintain

voltage based on the ambient air temperature. This permits optimum charging

and safety.
Thermal Runaway

Automatically stops charging to prevent battery from overheating.
Charging

Ensure that all of the charger components are in place and in good

working condition, including the plastic boots on the battery clips.
Connect the battery following the connection instructions described in

Using the Quick-Disconnect Cable Connectors section.
Connect the AC power following the precautions listed in Section 8.

If you’ve connected everything correctly, the CHARGING

(yellow)

LED should be lit indicating that the charger is charging. If the CHARG-
ING

(yellow) LED does not light, check the connections or have

the battery checked/replaced.

Using the Quick-Connect Cable Connectors

Connect either of the two output cable assemblies to the charger in seconds.

Make sure to place the charger on a dry, non-flammable surface like metal or

concrete.
BATTERY CLIPS: Connect the battery clip cable assembly to the charger.

Follow the safety instructions in sections 6 or 7 to connect the output clips to

the battery.
RING TERMINALS: The ring connectors permanently attach the battery provid-

ing easy access to quickly charge your battery. This application is appropri-

ate for motorcycles, lawn tractors, ATV’s and snowmobiles. To permanently

attach it to a battery, loosen and remove each nut from the bolts at the battery

terminals. Connect the red positive ring connector ring to the positive (POS,

P, +) battery terminal. Connect the black negative ring connector ring to the

negative (NEG, N, -) battery terminal. Replace and tighten the nuts to secure it.

Take care to keep both wires and plug away from metal and the engine hood.

Connect the ring connector cable assembly to the charger.
Aborted Charge

If charging can not be completed normally, charging will abort. When charging
aborts, the charger’s output is shut off, and the CHARGING

(yellow) LED

will blink. To reset after an aborted charge, either disconnect the battery or

unplug the charger.
Desulfation Mode

If the battery is left discharged for an extended period of time, it could become

sulfated and not accept a normal charge. If the charger detects a sulfated bat-

tery, the charger will switch to a special mode of operation designed for such

batteries.
Completion of Charge

Charge completion is indicated by the CHARGED

(green) LED. When

lit, the charger has stopped charging and switched to the Maintain Mode of

operation.
Maintain Mode

When the CHARGED

(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.
NOTE: The charger automatically switches between Charge Mode and
Maintain Mode as necessary. The CHARGED

(green) LED may cycle on

when the battery is at full charge and off when the voltage drops below a preset

level and the charger goes into Charge Mode. This cycle will continue, and the
CHARGED

(green) LED will stay on for longer periods of time as the bat-

tery becomes more fully charged.

CALCULATING CHARGE TIME

13.

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.
Find your battery’s rating on the chart below, and note the charge time given.

The times given are for batteries with a 50% charge prior to recharging. Add

more time for severely discharged batteries.

MAINTENANCE INSTRUCTIONS

14.

Before performing maintenance, unplug and disconnect the battery charger

14.1

(see Sections 6, 7 and 8).
After use, unplug the charger and use a dry cloth to wipe all battery corro-

14.2

sion and other dirt or oil from the terminals, cords, and the charger case.
Ensure that all of the charger components are in place and in good working

14.3

condition, including the plastic boots on the battery clips.
Servicing does not require opening the unit, as there are no user-service-

14.4

able parts.

STORAGE INSTRUCTIONS

15.

Store the charger unplugged, in an upright position. The cord will still con-

15.1

duct electricity until it is unplugged from the outlet.
Store inside, in a cool, dry place (unless you’re using an on-board Marine

15.2

Charger).
Do not store the clips on the handle, clipped together, on or around metal, or

15.3

clipped to cables.

TROUBLESHOOTING

16.

PROBLEM

POSSIBLE CAUSE

REASON/SOLUTION

Charger will not turn on

when properly con-

nected.

AC outlet is dead.

Poor electrical connec-

tion.

Severely discharged, but

otherwise good, battery.

Clips are not making a

good connection to the

battery.

Battery is defective.

Reverse connections at

battery.

Check for an open fuse or

circuit breaker supplying

the AC outlet.

Check the power cord

and extension cord for as

loose fitting plug.

The battery may not want

to accept a charge due to

a run-down state. Allow

the charging to continue

until the battery has had

a chance to recover suf-

ficiently enough to take a

charge. If more than 20

minutes, stop charging

and have the battery

checked.

Check for poor connec-

tion to battery and frame.

Make sure connection

points are clean. Rock

clips back and forth for a

better connection.

Have the battery checked.

Unplug the charger and

correct the lead connec-

tions.

Charger makes a loud

buzz or hum.

Transformer laminations

vibrate (buzz).

Shorted Diode Assembly

or Output Rectifier As-

sembly (hum).

No problem, this is a

normal condition.

Have charger checked by

a qualified technician.

CHARGING

(yel-

low) LED is flashing.

Indicates the charger is in

abort mode.

See “Aborted Charge”

in the OPERATING IN-

STRUCTIONS Section.

BEFORE RETURNING FOR REPAIRS

17.

When a charging problem arises, make certain that the battery is capable of

17.1

accepting a normal charge. Use a good battery to double check all connec-

tions, the AC outlet for a full 120-volts, the charger clips for correct polarity

and the quality of the connections from the cables to the clips and from the

clips to the battery system. The clips must be clean.
