Before Using Your Battery Charger
It is important to understand your charger's requirements. This section will tell you about your charger's electrical requirements and how to prepare a battery for charging.
Plugging
it in
Your charger should be grounded to reduce the risk of electrical shock. Your charger is equipped with an electrical cord that has an equipment grounding conductor and a grounding plug designed to be used on a 120 volt circuit. The plug must be plugged into an outlet that has been propedy installed and grounded in accordance with all local codes and ordinances. A TEMPORARY adapter may be used to connect the charger to a two-pole outlet if a properly grounded outlet is not available. Use the adapter ONLY until a properly grounded outlet can be installed by a qualified electrician.
A
WARNING: Improper adapter con-
nection can result in electrical shock.
Before using an adapter as illustrated, be certain that the center screw of the outlet plate is grounded. The green colored grounding clip of the adapter must be attached by a metal screw to a properly grounded outlet. If unsure whether outlet is properly grounded, contact a professional electrician. If necessary, replace the original outlet cover screw with a longer one that will secure the grounding clip to the outlet cover and make a ground connection to the grounded outlet.

Preparing
your battery
to be charged
It is important that you read and follow these guidelines while you are preparing to charge your battery. ˇ Make sure that you have a 12 volt leed-acid battery. ˇ Clean the battery terminals. Be careful to keep corrosion from getting in or around your eyes. ˇ If you have a battery with removable cell caps, if required, add distilled water to each cell until the battery acid reaches the level indicated by the manufacturer. This will help purge excessive gases from the calls. Be careful not to overfill. If you have a sealed battery without cell caps, no action is necessary. Continue to the next step listed below. ˇ Take time to read all battery manufacturer's specific precautions, such as removing or not removing cell caps while charging, and recommended rates of charge. ˇ Wear safety glasses. Sea additional "Personal Safety Precautions" on page 2. ˇ Be sure that the area around the battery is well ventilated while it is being charged. If ventilation is poor, gas can be manually blown away by using a piece of cardboard or other non-metallic matedal as a fan. ˇ If it is necessary to remove the battery from the vehicle to charge it, always remove the grounded terminal from the battery first. A spark may be caused if all accessories in the vehicle are not completely tumed off. NOTE: A marine battery installed in a boat must be removed and charged on shore.
Using Your Battery Charger
For best results from your battery charger, learn to use it properly. This section tells how to set the controls and how to charge a battery in and out of the vehicle.
Setting
the controls
All the controls for your charger are located on the front of the charger. Follow these instructions to obtain the correct charge level for your battery. SELECTOR SWITCHES
ID
2A 10A
I
50A ENGINE START
Two switches are used to select the type and rate of charge. ˇ Use the right switch to select the 2-amp, the 10amp charge rate or the 50-amp Engine Start feature. ˇ Use the left switch to select the type of battery: conventional/low maintenance or maintenance free/deep-cycle. ˇ Use the 2-amp setting to chCrge small batteries and the 10-amp setting for larger batteries. AMMETER The ammeter indicates the measured amount of amperes being drawn by the battery. When you first start charging a battery, the reading will be high, with the needle near 10 amps using the 10 amp charging rate. As the battery charges, the needle will begin to fall toward 0. When the battery is fully charged, the needle will point to 0 and the FULL CHARGE green LED will glow. The percent of charge scale is intended as a visual aid to simplify reading the state of charge of the battery. The meter is scaled for use with the 10 amp charge rate. For the 2 amp charge rate, use the red tdangle as your reference. When charging for 2 amps, the needle will begin close to the "R" on RATE and will drop to 0 when finished. The percent of charge is based on current drawn by the battery. For this reason, accuracy will vary with the size and battery type.

Arrange the power cord and charging leads carefully in order to avoid damage that could be caused by the hood, door, or moving engine parts. Keep clear of the fan blades, belts, pulleys, and other parts that can cause injury. Check the polarity of the battery posts as indicated on the battery case: POSITIVE (POS, P, or +) and NEGATIVE (NEG. N or -). NOTE: The positive post on top-post batteries is usually larger than the negative post. Identify which battery post is ground or connected to the chassis. THE NEGATIVE POST IS NORMALLY THE ONE THAT IS GROUNDED. To charge a negative grounded post system: Connect the red (POSITIVE) battery charger clamp to the ungrounded POSITIVE (POS, P, +) post of the battery. Then connect the black (NEGATIVE) clamp to a heavy, unpainted metal part of the chassis or engine block, away from the battery. Do not connect clamp to carburetor, fuel lines, or sheet metal parts. To charge a positive grounded post system: Connect the black (NEGATIVE) battery charger clamp to the NEGATIVE (NEG, N, -) ungrounded post of the battery. Then connect the red (POSITIVE) clamp to a heavy, unpainted metal part of the chassis or engine block. Do not connect clamp to carburetor, fuel lines, or sheet metal parts. IMPORTANT: Wear safety glasses and face away from the battery while making connections. Connect the clamp to the battery post and twist or rock back and forth to make a solid connection. This will help keep the clamps from slipping off the posts and causing sparks. Select the type and rate of charge with the Selector switch. Rug the power cord into a grounded AC outlet to begin charging. When the battery is fully charged, unplug the charger power cord before attempting to disconnect charger clamps. Standing away from the battery, remove the charger clamps in this order: (1) from the chassis connection and, (2) from the battery pest or terminal. Clean and store the battery charger in a dry location.

your battery outside the vehicle: Remove the battery from vehicle, making sure to disconnect grounded terminal first with all accessories and lights turned off in the vehicle. 2. Check the polarity of the battery posts as indicated on the battery case: POSITIVE (POS, P, +) and NEGATIVE (NEG, N, -). NOTE: On top-post batteries, the positive battery terminal usually has a larger diameter than the negative one. 3. Connect the red (POSITIVE) charger clamp to the POSITIVE post of the battery. Be sure to rock the clip back and forth to make a solid connection. 4. Attach a 6-gauge (AWG) or a 4-gauge (SAE) insulated battery cable of at least 24-inches in length to the NEGATIVE battery post. This cable will provide a safer connection because arcing and sparking will not occur directly over the battery. (The battery cable is not provided with the charger, but may be purchased at most automotive accessory outlets.) 5. Take the other end of the 6-gauge (AWG) or a 4gauge (SAE) insulated 24-inch cable and, standing as far away from the battery as possible, connect the black (NEGATIVE) lead of the charger to the free end of the cable. Rock the clamp to make a solid connection. IMPORTANT: Wear safety glasses and face away from the battery while making this final connection. 6. Select the type and rate of charge with the Selector Switch. 7. Plug the power cord into a grounded AC outlet to begin charging. 8. When the battery is fully charged, unplug the charger power cord before attempting to disconnect charger clamps. 9. Stand away from the battery and remove the charger leads from the NEGATIVE connection first, then from the POSITIVE battery post. 10. Clean and store the battery charger in a dry location.

Calculating
The Chart Method
charge times
ˇ Marine, or deep-cycle batteries are usually rated in Reserve Capacity (RC). ˇ 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-percent charge. Add more time for totally discharged batteries.
Use the following table to more accurately determine the time it will take to bdng a battery to full charge. First, identify where your battery fits into the chart. ˇ Small batteries -- motorcycles, garden tractors, etc. -- are usually rated in Ampere Hours (AH). For example: 6 to 12 AH, or 12 to 32 AH. ˇ Batteries in cars and smaller trucks are usually rated in Reserve Capacity (RC), Cold-Cranking Amps (CCA), or both.

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 Pement-of-Charge Tester. The following table will help you convert hydrometer readings to percent of charge values.
To calculate time needed for a charge: ˇ Find the percent of charge needed. (A battery at 50 percent charge that will be charged to 100 percent needs another 50 percent (.50). ˇ Multiply the Amp Hour rating by the charge needed (.50) and divide by the charger setting (2 or 10 amps). ˇ Multiply the result by 1.25 and you'll have the approximate time needed, in hours, to bring the battery to full charge.
1.265 1.225 1.155 1.120
100% 75% 25% 0%
0% 25% 75% t00%
ˇ Add one additional hour for a deep-cycle battery.
Example: Amo Hour Ratino x % of charoe needed x 1.25 -- hours Charger Setting of charge 100 (AH Ratlno) x .50 (˘haroe needed) x 1.25 = 6.25 10 (Charger Setting) hours l_0_0.J_-_.-- 5 x 1.25 = 6.25 10 You would need to charge your 100-Ampere Hour Battery for approximately 61/_hours at the 10-Amp charge rate using the above example.
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: Amp Hours = Reserve Caoacity + 16 2
Using the engine start feature
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. 1. Connect the charger to the battery. (Follow connecting instructions given in =Charging Your Battery in the vehicle" on page 7. 2. Select the Selector Switch on ENGINE START. 3. Crank the engine for no more than 10 seconds. If it does not start, wait at least four minutes before cranking again. In extreme cold, or if the battery is severely discharged, charge the battery for about 5 minutes in the 10 amp position before cranking the engine. 4. After the engine starts, unplug the charger power cord from the AC outlet. Then disconnect the charger from the battery. IMPORTANT: Do not try to start the engine without a battery in it. You could cause damage to the electrical system. If the engine does turn over, but never starts up, there is not a problem with the starting system, there is a problem somewhere else in the engine. STOP cranking the engine until the other problem has been identified and corrected.
Maintenance
and care
A minimal amount of care can keep your battery charger working propedy 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. Occasional cleaning of the case of the charger with a soft cloth will keep the finish shiny and help prevent corrosion.

Troubleshooting
Performance problems often result from little things that you can fix yourself. Please read through this table for a possible solution if a problem occurs. PROBLEM No ammeter reading. POSSIBLE CAUSE Clamps not making good connection. 2-amp charge rate. No AC power reaching charger. Circuit breaker in charger cycles on and off with a clicking sound, Shorted battery clamps. SOLUTION/REASONS Check for poor connection at battery. Make sure clamps and posts are clean. Ammeter needle will indicate little activity at the 2-amp charge rate. Check AC outlet and extension cords for loose fitting plug. Check for open fuse or circuit breaker supplying AC outlet. Separate the clamps. Circuit breaker cycles when current draw is too high. Check for worn cables and replace if needed. Have a Sears Service Center test the battery. Correct connections.
Shorted battery. Charger leads reversed on battery. Ammeter reads less than selected charge rate when charging. Extension cord too long or gauge too small. Battery has weak cell or sulfated plate. Battery is partially charged. Charger makes a loud buzz or hum. Transformer laminations vibrate (buzz). Shorted diode (hum). Short start cycle when when cranking engine. Drawing more than 50 amps for a period equal to or less than 10 seconds. Failure to wait for 4 minutes (240 seconds) between cranks.
Use shorter or heavier extension cord.
Sulfated battery will eventually take a normal charge if left connected. If the battery will not take a charge, have it tested by a Sears Service Center. Continue charging battery.
Continue charging. Buzz is not abnormal. Have charger tested by a Sears Service Center. Crank time varies with the amount of current drawn from the charger. If cranking draws more than 50 amps, crank time may be less than 10 seconds. Wait 4 minutes before next crank.
