IMPORTANT SAFETY INSTRUCTIONS

• Do not expose the charger to rain or snow.1.1
• Use only recommended attachments. Use of an attachment not recommended 1.2 or sold by Schumacher® Electric Corporation may result in a risk of fire, electric shock, injury to persons, or damage to property.
• To reduce the risk of damage to the electric plug or cord, pull by the plug rather 1.3 than the cord when disconnecting the charger.
• An extension cord should not be used unless absolutely necessary. Use of an 1.4 improper extension cord could result in a risk of fire and electric shock. If an extension cord must be used, make sure:
• That the pins on the plug of the extension cord are the same number, size, and shape as those of the plug on the charger.
• That the extension cord is properly wired and in good electrical condition.
• That the wire size is large enough for the AC ampere rating of the charger as specified in the table in Section 8.
• To reduce the risk of electric shock, unplug the charger from the outlet before 1.5 attempting any maintenance or cleaning. Simply turning off the controls will not reduce this risk.
• Remove personal metal items such as rings, bracelets, necklaces, and watches 1.6 when working with a lead-acid battery. A lead-acid battery can produce a short-circuit current high enough to weld a ring or the like to metal, causing a severe burn.
• Do not operate the charger with a damaged cord or plug; take it to a qualified 1.7 service person. (Call customer service at 1-800-621-5485.)
• Do not operate the charger if it has received a sharp blow, been dropped, or 1.8 otherwise damaged in any way; take it to a qualified service person. (Call customer service at 1-800-621-5485.)
• Do not disassemble the charger; take it to a qualified service person when 1.9 service or repair is required. Incorrect reassembly may result in a risk of fire or electric shock. (Call customer service at 1-800-621-5485.)

PERSONAL PRECAUTIONS

• Working in the vicinity of a lead-acid battery is dangerous. Batteries generate explosive gases during normal battery operation. For this reason, it is of utmost importance that you follow the instructions each time you use the charger.
• To reduce the risk of a battery explosion, follow these instructions and those published by the battery manufacturer and the manufacturer of any equipment you intend to use in the vicinity of the battery.
• Review the cautionary markings on these products and on the engine.
• This charger employs parts, such as switches and circuit breakers, that tend to produce arcs and sparks. If used in a garage, locate this charger 18 inches or more above floor level.
• NEVER smoke or allow a spark or flame in the vicinity of a battery or engine.
• Be extra cautious to reduce the risk of dropping a metal tool onto the battery. It might spark or short-circuit the battery or other electrical parts which may cause an explosion.
• Use this charger for charging LEAD-ACID batteries only. It is not intended to supply power to a low-voltage electrical system other than in a starter-motor application.
• Do not use this battery charger for charging dry-cell batteries that are commonly used with home appliances. These batteries may burst and cause injury to persons and damage to property.
• NEVER charge a frozen battery.
• NEVER overcharge a battery.

PREPARING TO CHARGE

• Risk of contact with battery acid. Battery acid is a highly corrosive sulfuric acid.
• Consider having someone close enough by to come to your aid when you work near a lead-acid battery.
• Have plenty of fresh water and soap nearby in case battery acid contacts your skin, clothing, or eyes.
• Wear complete eye and body protection, including safety goggles and protective clothing. Avoid touching your eyes while working near the battery.
• If battery acid contacts your skin or clothing, immediately wash the area with soap and water. If acid enters your eye, immediately flood the eye with cold running water for at least 10 minutes and get medical attention right away.
• If it is necessary to remove the battery from the vehicle to charge it, always remove the grounded terminal first. Make sure all of the accessories in the vehicle are off to prevent arcing.
• Be sure the area around the battery is well-ventilated while the battery is being 3.6 charged.
• Clean the battery terminals before charging the battery. During cleaning, keep 3.7 airborne corrosion from coming into contact with your eyes, nose, and mouth. Use baking soda and water to neutralize the battery acid and help eliminate airborne corrosion.
• Do not touch your eyes, nose, or mouth.
• Add distilled water to each cell until the battery acid reaches the level specified 3.8 by the battery manufacturer. Do not overfill. For a battery without removable cell caps, such as valve-regulated lead acid batteries (VRLA), carefully follow the manufacturer’s recharging instructions.
• Read, understand, and follow all instructions for the charger, battery, vehicle 3.9, and any equipment used near the battery and charger. Study all of the battery manufacturer’s specific precautions while charging and recommended rates of charge.
• Determine the voltage of the battery by referring to the vehicle owner’s manual 3.10 and make sure that the output voltage selector switch is set to the correct voltage. If the charger has an adjustable charge rate, charge the battery at the lowest rate first.
• Make sure that the charger cable clips make tight connections.

CHARGER LOCATION

• Locate the charger as far away from the battery as the DC cables permit.4.1
• Never place the charger directly above the battery being charged; gases from 4.2 the battery will corrode and damage the charger.
• Do not set the battery on top of the charger.4.3
• Never allow battery acid to drip onto the charger when reading the electrolyte 4.4 specific gravity or filling the battery.
• Do not operate the charger in a closed-in area or restrict the ventilation in any 4.5 way.

DC CONNECTION PRECAUTIONS

• Connect and disconnect the DC output clips only after setting all of the charger 5.1 switches to the “off” position and removing the AC plug from the electrical outlet. Never allow the clips to touch each other.
• Attach the clips to the battery and chassis, as indicated in steps 6.5, 6.6, 7.2, 5.2 7.3, and 7.4.

FOLLOW THESE STEPS WHEN THE BATTERY IS INSTALLED IN THE VEHICLE

• A spark near the battery may cause a battery explosion. To reduce the risk of a spark near the battery:
• Position the AC and DC cables to reduce the risk of damage by the hood, door 6.1, 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.
• Stay clear of fan blades, belts, pulleys, and other parts that can cause injury.6.2
• Check the polarity of the battery posts. The POSITIVE (POS, P, +) battery post 6.3 usually has a larger diameter than the NEGATIVE (NEG, N, -) post.
• Determine which post of the battery is grounded (connected) to the chassis. 6.4 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.
• For a negative-grounded vehicle, connect the POSITIVE (RED) clip from the 6.5 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.
• For a positive-grounded vehicle, connect the NEGATIVE (BLACK) clip from the 6.6 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.
• When disconnecting the charger, turn all switches off, disconnect the AC 6.7 cord, remove the clip from the vehicle chassis, and then remove the clip from the battery terminal.
• See CALCULATING CHARGE TIME for length of charge information

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:
• Check the polarity of the battery posts. The POSITIVE (POS, P, +) battery post 7.1 usually has a larger diameter than the NEGATIVE (NEG, N, -) post.
• Attach at least a 24-inch (61 cm) long 6-gauge (AWG) insulated battery cable 7.2 to the NEGATIVE (NEG, N, -) battery post.
• Connect the POSITIVE (RED) charger clip to the POSITIVE (POS, P, +) post 7.3 of the battery.
• Position yourself and the free end of the cable you previously attached to the 7.4 NEGATIVE (NEG, N, -) battery post as far away from the battery as possible – then connect the NEGATIVE (BLACK) charger clip to the free end of the cable.
• Do not face the battery when making the final connection.7.5
• When disconnecting the charger, always do so in the reverse order of the 7.6 connecting procedure and break the first connection while as far away from the battery as practical.
• A marine (boat) battery must be removed and charged on shore. To charge it 7.7 onboard requires equipment specially designed for marine use.

BATTERY CHARGING – AC CONNECTIONS

• This battery charger is for use on a nominal 120-volt circuit and has a grounded plug that looks like the plug illustrated. The charger must be grounded to reduce the risk of electric shock. The plug must be plugged into an outlet that is properly installed and grounded in accordance with all local codes and ordinances. The plug pins must fit the receptacle (outlet). Do not use an ungrounded system.
• 8.2 Never alter the AC cord or plug provided – if it does not fit the outlet, have a properly grounded outlet installed by a qualified electrician.
• An improper connection can result in a risk of an electric shock or electrocution. NOTE: The use of an adapter plug is not recommended.

*If the input rating of a charger is given in watts rather than in amperes, the corresponding ampere rating is to be determined by dividing the wattage rating by the voltage rating – for example:

1200 watts/120 volts = 10 amperes

If the input rating of a charger is given in watts rather than in amperes, the corresponding ampere rating is to be determined by dividing the wattage rating by the voltage rating – for example 1200 watts/120 volts = 10 amperes

ASSEMBLY INSTRUCTIONS
No assembly required

CONTROL PANEL
NOTE: Not all switches and LEDs are available on all models.

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 start area of the meter indicates a high rate of current being drawn from the charger. When cranking an engine, the meter needle will be at the extreme right side of the start area. The 2 amp charge rate may indicate some activity on the meter, although the meter does not have the resolution to display this low rate. For the 2 amp charge rate, a triangle has been provided. Its accuracy has been calibrated for use with small batteries.

Percent of Charge
The percent of charge scale is intended as a visual aid to help simplify reading the state of charge. It is scaled for use with the 6, 10, 12, 15 or 30 amp charge rate only. For the 2 amp charge rate, use the triangle. The percent of charge is based on the current drawn by the battery. For this reason, accuracy will vary with the size and battery type. Typically a 28 ampere-hour gel cell battery will draw less current at the end of the charge cycle than a 140 ampere-hour wet cell battery. This means that the indication for a fully charged large battery may be slightly less than 100%.

Battery Type Switch
Use this switch to set the type of battery to be charged.

• SLI – These initials stand for Starting, Lighting, and Ignition, which are the three basic functions that a battery has to perform on all normal vehicles. This battery type is usually used in cars, trucks, and motorcycles. These batteries have vent caps and are often marked “Low Maintenance” or “Maintenance-free”.
• This type of battery is designed to deliver quick bursts of energy (such as starting engines) and have a greater plate count.
• The plates will also be thinner and have somewhat different material compositions. Most Maintenance Free Batteries are SLI, otherwise known as Flooded, Regular or Standard Batteries. Regular batteries should not be used for deep-cycle applications.
• Deep-Cycle – Deep-cycle batteries are usually marked as “Deep-Cycle” or “Marine”. Deep-cycle batteries are usually larger than the other types. This type of battery has less instant energy but somewhat greater long-term energy delivery than regular batteries.
• Deep cycle batteries have thicker plates and can survive a number of discharge cycles.
• AGM – The Absorbed Glass Mat construction allows the electrolyte to be suspended in close proximity to the plate’s active material. In theory, this enhances both the discharge and recharge efficiency. Actually, the AGM batteries are a variant of Sealed VRLA (valve-regulated lead acid) batteries. Popular uses include high-performance engine starting, power sports, deep cycle, solar and storage battery.
• AGM batteries are typically good deep cycle batteries, and they deliver the best life performance if recharged before the battery drops below a 50 percent charge. If these AGM batteries are completely discharged, the cycle life will be around 300 cycles. This is true of most AGM batteries rated as deep cycle batteries.
• GEL – The Gel Cell is similar to the AGM style because the electrolyte is suspended, but different because technically the AGM battery is still considered to be a wet cell. The electrolyte in a GEL cell has a silica additive that causes it to set up or stiffen. The recharge voltages on this type of cell are lower than the other styles of lead acid battery.
• This is probably the most sensitive cell in terms of adverse reactions to over-voltage charging. Gel Batteries are best used in VERY DEEP cycle applications and may last a bit longer in hot weather applications. If the incorrect battery charger is used on a Gel Cell battery, poor performance, and premature failure are certain.

When antimony is known to be one of the materials used in the battery’s construction, that battery is a conventional/low-maintenance type. Some low- maintenance batteries have a relatively smooth top without any apparent battery filler caps. If, however, the battery manufacturer/distributor recommends periodic checking of the electrolyte level and provides access to the battery for water additions, the battery is probably a conventional/low- maintenance type.

Charge Rate Selector Switch (Voltage/Amp Selector)
Use this switch to set the maximum charge rate to one of the following.

• 2A Slow Charge Rate – Intended for charging small batteries such as those commonly used in garden tractors, snowmobiles, and motorcycles. The 2A rate can be used to warm or trickle-charge larger batteries.

• 6A, 10A, 12A, 15A Fast, and 30A Rapid Charge Rate – Use for charging automotive, marine, and deep-cycle batteries. Not intended for industrial applications.

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

• Voltage Selector Switch

• Use this switch to set the charger to charge a 6-volt, 12-volt, or 24-volt battery.
  NOTE : These chargers are not recommended for 8 or 16-volt systems.
  LED Indicators

• Full Charge – When lit, this LED indicates that the battery is fully charged and the charger has stopped charging and switched to the Maintain Mode of operation (Automatic chargers only).

• Power On – When lit, this LED indicates that there is AC power supplied to the battery charger.

• Check Battery – When lit, this LED indicates there is something wrong with the battery. Check the DC connections for an improper connection; otherwise, the battery may be bad.

OPERATING INSTRUCTIONS
Overview

1. Connect the battery following the precautions listed in Sections 6 and 7.
2. Select the appropriate settings for your battery.
3. Connect the AC power following the precautions listed in Section 8.

Automatic Charging
If the charger has an Automatic Charge Mode, it can perform an automatic charge. 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 first to pre- charge the battery for five minutes to get additional voltage into the battery for the charger to analyze.

Manual Charging
If the charger does not have an Automatic Charge Mode, you will be charging in Manual Mode. A manual charger will continue to charge and will not shut off. You must keep a visual check on the ammeter to determine when the battery is charged. Be sure to monitor the charging process 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.

Completion of Charge (Automatic Chargers Only)
When the FULL CHARGE (green) LED is lit, the charger has stopped charging and switched to the Maintain Mode of operation. If the 12V DEEP CYCLE battery type was selected, the CHARGED (green) LED comes on when the battery is charged enough for normal use.

Maintain Mode (Automatic Chargers Only)
When the FULL CHARGE (green) LED is lit, the charger has started to 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. The voltage is maintained at a level determined by the BATTERY TYPE selected.
NOTE: An Automatic charger automatically switches between Charge Mode and Maintain Mode as necessary. The FULL CHARGE (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 FULL CHARGE (green) LED will stay on for longer periods of time as the battery becomes more fully charged. This is not applicable to manual chargers.

Using the Engine Start feature (If equipped)
Your battery charger can be used to jump-start 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 well- ventilated area. Using the ENGINE START feature WITHOUT a battery installed in the vehicle could cause damage to the vehicle’s electrical system.

1. Set the charge rate switch and the timer (if equipped) 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 following the precautions described in Section 8.

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 5 seconds pass. If the engine does not start, wait 4 minutes before cranking again. This allows the battery and the charger 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 amp 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.

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 in the chart. NR means that the charger setting is NOT RECOMMENDED. Find your battery’s rating on the chart below and note the charge time given for each charger setting. The times given are for batteries with a 50% charge prior to recharging. Add more time for severely discharged batteries.

BEFORE RETURNING FOR REPAIRS
When a charging problem arises, make certain that the battery is capable 16.1 of accepting a normal charge. Use a good battery to double-check all connections, an AC outlet for a full 120 volts, 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. When a battery is very cold, partially charged, or sulfated, it will not draw 16.2 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. When an UNKNOWN OPERATING PROBLEM arises, please read the 16.3 complete manuals and call the customer service number for information that will usually eliminate the need for a 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. 1-800-621-54857:00 am to 5:00 pm Central Time Monday thru Friday
