12.OPERATING INSTRUCTIONS

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

1.Ensure that all of the charger components are in place and in good working condition, including the plastic boots on the battery clips.

2.Connect the battery following the connection instructions described in Using the Quick-Disconnect Cable Connectors section.

3.Connect the AC power following the precautions listed in Section 8.

4. 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.

13.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.

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.

BATTERY SIZE/RATING			CHARGING TIME
SMALL	Motorcycle,	6 - 12 AH	2 ½ - 4 hrs
BATTERIES	garden

	550 - 1000 CCA	80 - 190 RC	24 ½ - 46 ¼ hrs
MARINE/DEEP CYCLE		80 RC	23 ½ hrs
		140 RC	36 ¼ hrs
		160 RC	40 hrs
		180 RC	44 ¼ hrs

14.MAINTENANCE INSTRUCTIONS

14.1Before performing maintenance, unplug and disconnect the battery charger

(see Sections 6, 7 and 8).

14.2After use, unplug the charger and use a dry cloth to wipe all battery corro- sion and other dirt or oil from the terminals, cords, and the charger case.

14.3Ensure that all of the charger components are in place and in good working condition, including the plastic boots on the battery clips.

14.4Servicing does not require opening the unit, as there are no user-service- able parts.

15.STORAGE INSTRUCTIONS

15.1Store the charger unplugged, in an upright position. The cord will still con- duct electricity until it is unplugged from the outlet.

15.2Store inside, in a cool, dry place (unless you’re using an on-board Marine Charger).

15.3Do not store the clips on the handle, clipped together, on or around metal, or clipped to cables.

17.BEFORE RETURNING FOR REPAIRS

17.1When a charging problem arises, make certain that the battery is capable of 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.
