5.2Attach the clips to the battery and chassis, as indicated in sections 6 and 7.

6.FOLLOW THESE STEPS WHEN BATTERY IS INSTALLED IN VEHICLE

A SPARK NEAR THE BATTERY MAY CAUSE A

BATTERY EXPLOSION. TO REDUCE THE RISK OF A SPARK NEAR THE BATTERY:

6.1 Position the AC and DC cables to reduce the risk of damage by the hood, door and moving or hot engine parts. NOTE: If it is necessary to close the

hood during the charging process, ensure that the hood does not touch the metal part of the battery clips or cut the insulation of the cables.

6.2Stay clear of fan blades, belts, pulleys and other parts that can cause injury.

6.3Check the polarity of the battery posts. The POSITIVE (POS, P, +) battery post usually has a larger diameter than the NEGATIVE (NEG, N, -) post.

6.4Determine which post of the battery is grounded (connected) to the chassis. If the negative post is grounded to the chassis (as in most vehicles), see step 6.5. If the positive post is grounded to the chassis, see step 6.6.

6.5For a negative-grounded vehicle, connect the POSITIVE (RED) clip from the battery charger to the POSITIVE (POS, P, +) ungrounded post of the battery. Connect the NEGATIVE (BLACK) clip to the vehicle chassis or engine block away from the battery.

Do not connect the clip to the carburetor, fuel lines or sheet-metal body parts. Connect to a heavy gauge metal part of the frame or engine block.

6.6For a positive-grounded vehicle, connect the NEGATIVE (BLACK) clip from the battery charger to the NEGATIVE (NEG, N, -) ungrounded post of the battery. Connect the POSITIVE (RED) clip to the vehicle chassis or engine block away from the battery. Do not connect the clip to the carburetor, fuel lines or sheet-metal body parts. Connect to a heavy gauge metal part of the frame or engine block.

6.7Connect charger AC supply cord to electrical outlet.

6.8When disconnecting the charger, turn all switches to off, disconnect the AC cord, remove the clip from the vehicle chassis and then remove the clip from the battery terminal.

6.9See CALCULATING CHARGE TIME for length of charge information.

7.FOLLOW THESE STEPS WHEN BATTERY IS OUTSIDE VEHICLE

A SPARK NEAR THE BATTERY MAY CAUSE A BATTERY EXPLOSION. TO REDUCE THE RISK OF A SPARK NEAR THE BATTERY:

7.1 Check the polarity of the battery posts. The

POSITIVE (POS, P, +) battery post usually has a larger diameter than the NEGATIVE (NEG, N, -) post.

7.2Attach at least a 24-inch (61 cm) long 6-gauge (AWG) insulated battery cable to the NEGATIVE (NEG, N, -) battery post.

7.3Connect the POSITIVE (RED) charger clip to the POSITIVE (POS, P, +) post of the battery.

11.CONTROL PANEL Timer

•Timer Setting: The timer allows you to set a specified time for charging. After the timer expires, the charger stops charging your battery. The main function of the timer is to prevent over charging while allowing a battery time to obtain a satisfactory charge. To properly set the timer, you must know the size of the battery in ampere hours or reserve capacity in minutes and the state of charge. It is important that you determine the appropriate state of charge of your battery as specified in Section 13 and set the timer accordingly.

•Hold: This position defeats the timer function, allowing for continuous operation.

•Automatic Modes: Put the timer in the HOLD position when using the battery charger in one of the Automatic Modes (4, 20 or 70 amp), otherwise the timer will stop the charging process when the time expires regardless of whether

it is complete or not. The CHARGED (green) LED will light when charging is complete and the charger goes into Maintain Mode. The charger will not shut off.

•Manual Modes: Put the timer in the HOLD position when using the battery charger in the Manual Mode (40 amp) and when you want to charge more than 2¼ hours. Be sure to monitor the charging progress and stop it when the battery is charged. Not doing so may cause damage to your battery or may cause other personal property damage or personal injury.

Ammeter

The Ammeter indicates the amount of current, measured in amps, that is being drawn by the battery. As a battery takes on a charge, it draws less current from the charger. Correspondingly, the meter will show less current being drawn by the battery. When the current stops decreasing, the battery is charged. The 4 amp charge rate may indicate some activity on the meter, although the meter does not have the resolution to display this low rate.

Voltmeter

The voltmeter indicates the voltage at the battery terminals. The charger need not be plugged into an AC outlet. The timer should be in the OFF position. Then connect the charger following the instructions in Sections 6 and 7. Observe the meter indication.

Keep in mind that this reading is only a battery voltage reading, a false surface charge may mislead you. We suggest that you turn on the headlights for a couple of minutes before you read the meter. Read it a couple of minutes after you have shut the headlights off. If the reading is less than 10.5-volts, the battery may be bad or the connection at the charger may be poor. If the reading is 10.5-volts to 12.8-volts, the battery is low – recharge it. If the reading is above 12.8-volts, the battery is charged.

Charge Rate Selector Switch

Use the Charge Rate selector switch to select the charge rate or engine starting setting you require.

•4A Slow Charge Rate – Intended for charging small batteries such as those commonly used in garden tractors, snow mobiles and motorcycles.

•20A and 40A Fast and 70A Rapid Charge Rate – Use for charging automotive, marine and deep-cycle batteries. Not intended for industrial applications.

•300A Engine Start – Provides 300 amps for cranking an engine with a weak or run down battery. Always use in combination with a battery.

12.OPERATING INSTRUCTIONS

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

The charger automatically reduces the current if it detects the battery may be getting too hot. This is a safety precaution.

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. Make sure the electrolyte

(battery liquid) in each cell is at the correct level.

2.Set the charge rate switch and the timer to the OFF position.

•7 •

3.Connect the battery following the precautions listed in Sections 6 and 7.

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

5.Select the desired charge rate. NOTE: The 40 amp Manual rate is a manual mode and will overcharge a battery if permitted to operate for extended periods of time. Monitor the charging process often.

6.Turn the timer to HOLD or the selected charge time if using the 40 amp Manual Mode.

7.To disconnect the charger, reverse the procedure.

NOTE: This charger is equipped with a safe start feature. In the Automatic 4, 20 and 70 amp charge rates it will not supply current to the battery clips until a battery is properly connected. Unlike traditional chargers, the clips will not spark if touched together. In the Manual 40 amp charge rate, the clips will spark if accidently touched together.

Automatic Charging Mode

When an Automatic Charge is performed, the charger switches to the Maintain Mode

(see below) automatically after the battery is charged. For a battery with a starting voltage under 1 volt, use the Manual Mode (see Manual Charging section) first to pre-charge the battery for five minutes to get additional voltage into the battery for the charger to analyze.

Manual Charging Mode

When you select the 40 Amp Manual Mode charge rate, you will be charging in manual mode. You must set the timer to the proper time (see Timer section). Be sure to monitor the charging procedure and stop it when the battery is charged. Not doing so may cause damage to your battery or result in other property damage or personal injury.

Aborted Charge

If charging can not be completed normally, charging will abort. When charging aborts, the charger’s output is shut off. 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 battery, the charger will switch to a special mode of operation designed for such batteries. If successful, normal charging will resume after the battery is desulfated. Desulfation could take 8 to

10 hours. If desulfation fails, charging will abort (see Aborted Charge section).

Completion of Charge

Charge completion is indicated by the CHARGED (green) LED. When lit, the charger has switched to the Maintain Mode of operation.

Maintain Mode (Float-Mode Monitoring)

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 will 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 battery becomes more fully charged.

Using the Engine Start feature

Your battery charger can be used to jumpstart your car if the battery is low. Follow these instructions on how to use the ENGINE START feature.

Follow all safety instructions and precautions for charging your battery. Wear complete eye protection and clothing protection. Charge your battery in a wellventilated area.

Using the ENGINE START feature WITHOUT a battery installed in the vehicle could cause damage to the vehicle’s electrical system. NOTE: If you have charged the battery and it still will not start your car, do not use the engine start feature, or it could damage the vehicle’s electrical system.

• 8 •

1.Set the charge rate switch and the timer to the OFF position.

2.With the charger unplugged from the AC outlet, connect the charger to the battery following the instructions given in Section 6 (FOLLOW THESE STEPS WHEN THE BATTERY IS INSTALLED IN A VEHICLE).

3.Plug the charger AC power cord into the AC outlet, and then move the timer switch from OFF to the HOLD position.

4.With the charger plugged in and connected to the battery of the vehicle, set the charge rate selector switch to the engine start position.

5.Crank the engine until it starts or 3 seconds pass. If the engine does not start, wait 3 minutes before cranking again. This allows the charger and battery to cool down.

NOTE: During extremely cold weather, or if the battery is under 2 volts, charge the battery for 5 minutes before cranking the engine.

6.If the engine fails to start, charge the battery for 5 more minutes before attempting to crank the engine again.

7.After the engine starts, move the charge rate selector switch to the OFF position and unplug the AC power cord before disconnecting the battery clips from the vehicle.

8.Clean and store the charger in a dry location.

NOTE: If the engine does turn over but never starts, there is not a problem with the starting system; there is a problem somewhere else with the vehicle. STOP cranking the engine until the other problem has been diagnosed and corrected.

Using the Battery Voltage Tester

Overview

This battery charger has a built-in voltmeter to test your battery’s state of charge. The charger does not have a built in load tester. As such, a recently charged battery could have a temporarily high voltage due to what is known as “surface charge”. The voltage of such a battery will gradually drop during the period immediately after the charging system is disengaged. Consequently, the tester could display inconsistent values for such a battery. For a more accurate reading, the surface charge should be removed by temporarily creating a load on the battery, such as by turning on lights or other accessories for a couple of minutes before you read the display. Read it a couple of minutes after you have shut the headlights off.

Testing Sequence: There are four basic steps required to test the battery state of charge:

1.With the charger unplugged from the AC outlet, connect the charger to the battery following the instructions given in Sections 6 and 7.

2.Set the charge rate switch and the timer to the OFF position.

3.Plug the charger AC power cord into the AC outlet, following the instructions given in Section 8.

4.Read the voltage on the voltmeter.

Using the Alternator Performance Tester

Overview

This battery charger has a built-in alternator tester that displays an estimate of the alternator’s relative output compared to normal alternators. The alternator % values displayed should be taken as a general reference, not a precise diagnosis. The alternator tester functions the same as the built-in battery voltage tester (see previous section for details) with a few differences.

Testing Sequence: There are four basic steps required to operate this unit as an alternator tester:

1.With the charger unplugged from the AC outlet, connect the charger to the battery following the instructions given in Sections 6 and 7.

2.Set the charge rate switch and the timer to the OFF position.

3.Plug the charger AC power cord into the AC outlet, following the instructions given in Section 8.

4.Start the vehicle and turn on the vehicle’s headlights. Read the voltage on the voltmeter.

•9 •

General Charging Notes

Fan: The charger is designed to control its cooling fan for efficient operation.

Consequentially, it is normal for the fan to start and stop when maintaining a fully charged battery. Keep the area near the charger clear of obstructions to allow the fan to operate efficiently.

Voltage: The voltage displayed during charging is the charging voltage and is usually higher than the battery’s resting voltage.

13. CALCULATING CHARGE TIME

The Hydrometer or Electronic Method

To find the time needed to fully charge your battery, determine the battery’s charge level with a hydrometer or electronic Percent-of-Charge Tester. The following table will help you convert hydrometer readings to percent of charge values.

	SPECIFIC GRAVITY	PERCENT OF CHARGE	PERCENT OF CHARGE
			NEEDED
	1.265	100%	0%
	1.225	75%	25%
	1.155	25%	75%
	1.120	0%	100%

When you know the percent of charge and the Amp Hour (AH) rating of your battery, you can calculate the approximate time needed to bring your battery to a full charge.

To convert Reserve Capacity to Amp Hours, divide Reserve Capacity by 2, and add 16:

Example:

Amp Hour Rating = Reserve Capacity + 16 2

NOTE: The Reserve Capacity can be obtained from the battery specification sheet or the owner’s manual.

To calculate the time needed for a charge:

1.Find the percent of charge needed. (A battery at 50 percent charge that will be charged to 100 percent needs another 50 percent (.50)).

2.Multiply the Amp Hour Rating by the charge needed (.50) and divide by the charge rate.

3.Multiply the results by 1.25 and you will have the total time needed, in hours, to bring the battery to full charge.

4.Add an additional hour for a deep-cycle battery.

Example:

Amp Hour Rating x % of charge needed x 1.25 = hours of charge Charger Setting

100 (AH Rating) x .50 (charge needed) x 1.25 = 3.125 hours 20 (Charger Setting)

100 x .50 x 1.25 = 3.125

20

You would need to charge your 100-Ampere Hour Battery for a little more than 3 hours at the 20-Amp charge rate using the above example.

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 connections, 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.

17.2When a battery is very cold, partially charged or sulfated, it will not draw the full rated amperes from the charger. It is both dangerous and damaging to a battery to force higher amperage into it than it can effectively use in recharging.

17.3When an UNKNOWN OPERATING PROBLEM arises, please read the complete manual and call the customer service number for information. This will usually eliminate the need for return.

If the above solutions do not eliminate the problem or for information about troubleshooting or replacement parts, call toll-free from anywhere in the U.S.A.
