HELP US HELP YOU--

Remember:

???Place charger as far away from the battery being charged as the charger cables will permit.

???Do not expose charger to rain or

snow.

???Never charge a frozen battery. If battery fluid (electrolyte) becomes frozen, bring battery into a warm area to thaw before you begin charging.

???Never allow battery acid to drip on charger when reading specific gravity or filling battery.

???Never set a battery on top of the charger.

???Never place charger directly above battery being charged. The gases from the battery will corrode and damage the charger.

???Never use charger for charging dry- cell batteries that are commonly used with home appliances like radios, stereos, remote controls, etc. These batteries may burst and cause personal injury.

???Never touch the battery clamps together when the charger is on. You could cause a spark.

???Never operate charger if it has received a hard blow, been dropped, or otherwise damaged. Take it to a qualified professional for inspection and repair.

???Be sure to position the charger power cord to prevent it from being stepped on, tripped over, or damaged.

???Never pull out the plug by the cord when unplugging the charger. Pulling on the cord may cause damage to the cord or the plug.

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

For your own personal safety, please follow the following precautions:

???Wear complete eye and clothing protection when working with lead- acid batteries,

???Be 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.

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 spark or short circuit the battery or another electrical device that may cause an explosion.

???Always operate your 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.

It is important that you read and follow these charge your battery.

???Make sure that you have a 6 volt or 12 volt lead-acid battery.

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

???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 battery manufacturer's specific precautions, such as removing or not removing

guidelines while you are preparing to

vent caps while charging, and recommended rates of charge.

???Wear safety glasses. See additional "Personal Safety Precautions" on page 4.

???Be sure that the area around the battery is well ventilated while it is being charged.

???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 battery installed in a boat must be removed and charged on shore.

Read the following pages before using your charger. The tips below serve only as a guide for specific situations.

If your vehicle won't start: You don't need to fully charge a battery to start your vehicle. If the charger won't start your vehicle using the 75 Amp Start rate, try charging the battery using the 12 Amp rate for f0 or 15 minutes. That should charge the battery enough to allow the 75A Start rate to start the vehicle. If the vehicle will then be operated continuously for an extended period (such as a long drive), the

vehicle could charge the battery back to normal during that period. If the vehicle will only be operated for a short period (short drive), the battery might need to

be charged again before it could start the vehicle.

Reviving your battery: If you only

wish to charge your battery enough to

operate your vehicle, you don't need to wait for the entire charging process to be completed. When the charger displays three Battery Status LEDs (see pages 8, 9, and 12), the battery has been charged as much as by most chargers. The vehicle should then start and operate normally.

Completing an interrupted charge: If the charging process has been inter- rupted and restarted after three Battery Status LEDs were lit, the charger will go straight to Maintain Mode (see pages 7 & 9). However, if the original charge was started using 12 Amps, the charge can often be completed using 2 Amps.

For best results from your battery charger, learn to use to set the controls and how to charge a battery in and

it properly. This section tells how out of a vehicle.

2 Amp charge rate: Intended for charging of small batteries such as those commonly used in garden tractors, snowmobiles and motorcycles. It is not to be used as a trickle charger for larger batteries.

12 Amp charge rate: Use for charging automotive batteries, marine starter batteries and deep cycle batteries. Not intended for industrial applications and very large batteries where 20 amp and greater charge rates are required.

75 Amp engine start: Provides 75 amps for cranking an engine with a weak or run down battery. Always use in combination with a battery.

Charging: Both the 2 and 12 amp

charge rates perform an automatic

charge function. During the first few seconds of operation, an analytical check of the battery is performed. If the charger does not detect a properly connected battery, the red "check" LED will light continuously until such a " battery is detected. If a battery will not accept a normal charge, the charger will switch to a special mode of operation designed for such batteries.

Indication of this special mode is the flashing of the first amber LED in the charge status display. If successful, normal charging will resume. If not, a red LED will blink indicating that charging has been aborted. When the amber LED is on but not flashing, normal charging is in progress. Charge completion is indicated by a green LED; at this point the charger has switched to the Maintain Mode of operation.

Maintain Mode: When the green LED is lit, the charger has started Maintain

Mode. This mode of operation is also known as Float-Mode Monitoring. In this mode, the charger keeps the battery fully charged by delivering a small current, when necessary.

Battery types: The charger offers a se- lection of three different types of batteries:

???12 Volt TYPE 1 for most 12 volt Low- Maintenance, AGM, and Gel Cell batteries;

???12 Volt TYPE 2 for 12 volt Deep

Cycle and Maintenance-Free batteries;

???6 Volt for 6 volt batteries.

7

NOTE: The charger defaults to Type 1 when first plugged in or when discon- nected from a battery. The 6 VOLT button must then be pressed before charging a 6 volt battery.

With the exception of AGM and gel cell batteries, all other battery types may or may not have vent caps. Vent caps are located on top of the battery and provide a means to add distilled water when needed. Batteries should be marked

with their type. If charging a battery that is not marked, check the manual of the item that uses the battery. If the battery type is unknown, use the Type 1 position. Make sure the battery complies with the safety instructions on page 3.

Engine cranking: When the 75A Start rate is selected, the charger waits until the engine is actually being cranked before delivering 75 amps for engine start. Note: The charger delivers a charge of 3 to 7 amps while waiting for the engine to be cranked and will reset if the engine is not cranked within 15 minutes. Cranking is allowed for up to 3 seconds, then the charger shuts down for a 4 minute cool down period. During the cool down period the Start LED will blink. After 4 minutes, the Start LED will light continuously, indicating that another crank cycle can be performed.

Battery Status LEDs: The status of the battery is indicated by a row of six LED's.The first LED is red; it will light under the following conditions:

1.The charger is not connected to a bat- tery. Red LED lights continuously.

2.The charger is reverse-connected to a battery. Red LED lights continuously.

3.The charge cycle was not completed within 24 hours. Red LED blinks.

4.The battery could not be charged in a normal manner. This could be due to a battery with a partially shorted or open cell, sulfated battery plates or electro- lyte out of balance. Red LED blinks.

The next four LED's are amber. First, only the leftmost amber LED will light. Then two, then three, and eventually all four amber LED's will light. Refer to "Estimating Charge Time" on page 12 for more information.

The sixth LED is green and lights to indi- cate that charging is complete. When the green LED lights, the amber LED'swill turn oft and the charger starts Maintain Mode.

See the Control Panel table on the next

page.

Setup and Operating: Follow all safety and connecting procedures in this manual Located above each button on the control pad is an amber LED that lights to indicate that the selection is active.

When plugged in, the charger will automatically default to the 2 AMP /

TYPE 1 position. You may then select the charge rate and battery type. For example, if you'recharging a large 12-volt deep cycle battery, press the 12 AMP 6 & 12V button and the 12 VOLT TYPE 2 button. Note: If you press a charge rate or battery type button after charging has started, the charger will restart the charging process. Refer to "Estimating Charge Time" on page 12 for more information.

When selecting the Start position, you do not have to select a battery type. All indicator lights will turn off except for the light above the Start button. The red LED will also light if a properly con- nected battery has not been detected. The start position can only be used for 12-volt systems, not 6-volt systems.

X indicates panel lights that continuously glow. B indicates panel lights that blink on and off.

This charger adjusts the charging time in order to charge the battery completely, efficiently, and safely. The microprocessor automatically makes all necessary calculations. However, this section includes guidelines that can be used to estimate charging time.

The duration of the charging process de- pends on each of three factors.

1.Battery state: A battery that has only been slightly discharged could be charged in only a few hours. How- ever, the same battery could take 24 hours to charge if it is very weak. Battery state can be estimated by using a voltmeter to measure the battery voltage or by using a State- of-Charge Tester. The lower the reading, the longer the charging process will take.

2.Battery rating: A higher rated battery will take much longer to charge than a lower rated battery under the same conditions. A battery's rating may be indicated in Ampere hours (Ah), Reserve Capacity (RC), or Cold Cranking Amps (CCA). The lower the rating, the quicker the charging will be completed. For example, a very small battery might be rated for 6 Ah and charge in 4 hours, but a very large battery might be rated for 100 Ah and require 24 hours to charge completely.

3.Charge rate: The charge rate is measured in amps. This charger provides charge rates of 2 Amps and 12 Amps. Note: the 75 Amp rate is intended for Engine Start only, NOT continuous charging. A higher

charge rate results in a faster charge. Note: The 2 Amp rate might be too low to charge a higher rated baftery within the 24 hour time limit the

charger allows. However, some smaller batteries, such as motor- cycle and tractor batteries, have a maximum recommended charge rate much less than 12 Amps. Such batteries should be charged using the 2 Amp setting.

This charger starts charging at the selected rate (2 or 12 Amps) and eventually reduces the charge rate in a precisely controlled manner. After the charging process has started, the Battery Status LEDs can be used to estimate the charge time as explained below.

???Fled LED: Checking for properly connected battery, not charging (no output).

???1 Amber LED: Battery detected, charging started, 3 to 10 seconds from start.

2 Amber LEDs: Charging roughly

20% to 25% complete, 1 to 6 hours from start.

???3 Amber LEDs: Charging roughly

35% to 50% complete, 3 to 8 hours from start. Battery charged enough for use in vehicle. Note: If charging is restarted after this point, the charger may go straight to Maintain Mode (Green LED).

???4 Amber LEDs: One hour left, battery virtually "good as new", 5 to 15 hours from start.

Green LED: Charge complete,

battery at maximum charge state, 6 to 16 hours from start.

12

A minimal amount of care can keep your battery charger working properly for years.

1.Clean the clamps each time you are finished charging. Wipe off any battery fluid that may have come in contact with the clamps to prevent corrosion.

2.Coil the input and output cords neatly when storing the charger. This will help prevent accidental damage to the cords and charger.

3.Occasional cleaning of the case of the charger with a soft cloth will keep

the finish shiny and help prevent corrosion.
