Do not operate the charger if it has a damaged power cord or plug. Have the cord replaced.

• Wear complete eye and clothing protection when working with leadacid batteries.

• Make sure that someone is within range of your voice to come to your aid if needed while you work with or are near a lead-acid battery.

• Have plenty of fresh water and soap nearby for use in case battery acid contacts your eyes, skin, or clothing. If this happens, wash immediately with soap and water. Then get medical attention.

• Avoid touching your eyes while working with a battery. Acid particles (corrosion) may get into your eyes. If this occurs, flush eyes immediately with running cold water for at least 10 minutes. Then immediately get medical attention.

• Never charge a frozen battery.

• Remove all personal metal items

from your body such as rings, bracelets, necklaces and watches, while working with a lead-acid battery. A battery can produce a short circuit current high enough to weld a ring (or the like) to metal, causing a severe burn.

• Take care not to drop any metal tool

or metal object onto the battery. This may result in a spark or short circuit across the battery or another electrical device that may cause an explosion.

• Always operate the battery charger in

an open, well-ventilated area.

• Never smoke or allow a spark or

flame in the vicinity of the battery or engine. Batteries generate explosive gases.

• Neutralize any acid spills thoroughly

with baking soda before attempting to clean up.

BEFORE USING YOUR BATTERY CHARGER

It is important to understand the charger’s requirements. This section explains the charger’s electrical requirements and how to prepare a battery for charging.

PLUGGING IT IN

Your charger requires a 120V AC receptacle installed according to all local codes and ordinances.

extension cord, please make sure that you follow these guidelines:

• Make sure that pins on plug of extension cord are the same number, size, and shape as those of plug on charger.

PREPARING YOUR BATTERY TO BE CHARGED

It is important that you read and follow these guidelines while you are preparing to charge the battery.

• Make sure that you have a 12 volt lead-acid battery. Determine voltage of battery by referring to vehicle owner’s manual. Charge battery initially at charger’s lowest rate.

• Clean the battery terminals. Be careful to keep corrosion from getting in or around your eyes.

• Wear safety glasses. See additional “Personal Safety Precautions” on page 4.

• For batteries with removable vent caps, if required, add distilled water to each cell until the battery acid reaches the level recommended by the manufacturer. This will help purge excessive gases from the cells. Be careful not to overfill. If you have a sealed battery with non-removable vent caps, no action is necessary.

• Take time to read all of the battery manufacturer’s specific precautions, such as removing or not removing vent caps while charging, and recommended rates of charge.

• Be sure that the area around the battery is well ventilated while it is being charged. Gas can be forcefully blown away by using a piece of cardboard or other nonmetallic material as a fan.

• If it is necessary to remove the battery from the vehicle to charge it, always remove the grounded terminal from the battery first. Turn off all vehicle accessories to avoid sparks from occurring.

• NOTE: A marine (boat) battery installed in a boat must be removed and charged on shore.

USING THE BUILT-IN BATTERY TESTER

OVERVIEW

The charger has a built-in battery tester that displays either an accurate battery voltage or an estimate of the battery’s relative charge based on the battery voltage and a scale set by the Battery Council International.

TESTING SEQUENCE

There are four basic steps required to use the charger as a battery tester.

1. Connect the charger battery clamps to the battery. Be sure to follow all of the precautions listed under “OPERATING INSTRUCTIONS”.

2. Connect the charger power cord to a 120 VAC outlet. Again, be sure to follow all of the precautions listed under “OPERATING INSTRUCTIONS”.

3. If necessary, press the Battery Type button until the correct type is indicated.

4. Read the voltage on the digital LED or press the display mode button to set the tester to “Battery %” and read the battery percent.

TESTER AND CHARGER

When first turned on, the charger operates only as a tester, not as a charger. To continue to use it as only a tester, avoid pressing the CHARGE RATE switch button. Selecting a charge rate activates the battery charger and deactivates the tester.

POWER-UP IDLE TIME LIMIT

If no switch button is pressed within ten minutes after the unit is first powered up, the unit will automatically switch from tester to charger, if a battery is connected. In that case, the unit will be set for the 2A charge rate and REGULAR battery type.

TESTER WITHOUT TIME LIMIT

If either the DISPLAY MODE or BATTERY TYPE button is pressed within the first ten minutes after the unit is powered up, the unit will remain a tester (not a charger) indefinitely, unless a charge rate is selected.

TESTING AFTER CHARGING

After the unit has been changed from tester to charger (by selecting a charge rate), it remains a charger as long as it has power. Disconnect and reconnect the power to change the unit back to a tester.

TESTER STATUS LEDs

When the charger is operating as a battery tester, the status LEDs light under the following conditions.

• The CHARGED (green) LED will light if a fully charged battery is tested.

• The CHARGING (yellow) LED does not light in the battery test mode.

• The CHECK (red) LED will light if a battery is not properly connected.

• When the tester display mode is set to voltage, none of the Status LEDs light as long as a voltage greater than one volt is detected.

INITIAL PERCENT CALCULATION

When a battery % is calculated for the first time after connecting a battery, the digital LED will show two dashes (“--”) for several seconds while the tester analyzes the battery.

NOTES FOR TESTING BATTERY %

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.

The battery % ranges from 0 to 100. The battery tester is only designed to

test 12V batteries. Testing a device with a rapidly changing voltage could yield unexpected or inaccurate results.
