B. PERSONAL SAFETY PRECAUTIONS
1.WARNING: Wear complete eye protection and clothing protection, when working with lead-acid batteries.
2.Make sure someone is within range of your voice or close enough to come to your aid when you work with or near a lead-acid battery.
3.Have plenty of fresh water and soap nearby for use if battery acid contacts skin, clothing, or eyes. If battery acid contacts skin or clothing, wash immediately with soap and water.
4.Avoid touching your eyes while working with a battery. Acid particles (corrosion) may get into your eyes! If acid enters your eye, immediately flood eye with running cold water for at least
10 minutes. Get medical attention immediately.
C. Plugging it in
WARNING: Electrical Shock Hazard. Be sure that power cord fits properly into outlet. If not, have a qualified technician install a proper outlet. Never alter the AC cord or plug provided. Improper connection can result in electrical shock.
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 properly installed and grounded in accordance with all local codes and ordinances.
5.Remove all personal metal items such as rings, bracelets, necklaces, and watches 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.
6.Take care not to drop a metal tool or other metal onto the battery. Metal may cause sparking or short circuit the battery or another electrical device. Sparking may cause an explosion.
7.Always operate battery charger in an open well ventilated area.
8.NEVER smoke or allow a spark or flame in the vicinity of the battery or engine. Batteries generate explosive gases!
9.Neutralize any acid spills thoroughly with baking soda before attempting to clean up.
FIGURE 1 – PLUGGING IT IN
DANGER: Never alter the AC cord or plug provided. If it will not fit outlet, have a proper outlet installed by a qualified electrician. Improper connection can result in a risk of an electrical shock. DANGER: Before using an adapter, as illustrated, be certain that the center screw of the outlet plate is grounded. The green-colored rigid ear or lug extending from the adapter must be connected to a properly grounded outlet. Make certain it is grounded. If necessary, replace original outlet cover plate screw with a longer screw that will secure adapter ear or lug to outlet cover plate and make ground connection to grounded outlet.
D. PREPARING TO CHARGE
It is important that you read and follow these guidelines while you are preparing to charge your battery.
•Make sure that you have a 12 volt lead-acid battery.
•Clean the battery terminals. Be careful to keep corrosion from getting in or around your eyes or on your hands.
•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 cells. 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.
•Taketimetoreadallbatterymanufacturer’sspecificprecautions, such as removing or not removing cell caps while charging, and recommended rates of charge.
•Wear safety glasses. See additional "Personal Safety Precautions" on page 2.
•Be sure that the area around the battery is well ventilated while it is being charged. If ventilation is poor, any gases emitted from the battery can be manually blown away by using a piece of cardboard or other non-metallic 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.
A spark may be caused if all accessories in the vehicle are not completely turned off.
E. OPERATING INSTRUCTIONS: CHARGING BATTERY IN VEHICLE
NOTE: A marine (boat) boat battery must be removed and charged on shore. To charge it on board requires equipment specially designed for marine use.
When charging battery in the vehicle, take care to determine the battery type and which post is grounded. To reduce risk of a spark near battery, follow these steps when battery is installed in vehicle. WARNING: A spark near battery may cause battery explosion.
1.Arrange the power cord and charging cords carefully in order to avoid damage that could be caused by the hood, door, or moving engine parts.
2.Keep hands, hair, clothing and jewelry clear of the fan blades, belts, pulleys, and other parts that can cause injury.
3.Check the polarity of the battery posts using the identification marks on the battery case: POSITIVE (POS,P, +) and NEGATIVE (NEG,N, –).
4.Identify which post of the battery is grounded or connected to the chassis. The negative post is normally the one that is grounded.
5.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 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, away from the battery. 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.

select CHARGE RATE
The SELECT CHARGE RATE allows you to select the correct battery voltage and amp draw rate to match your charging needs. Read the following operating instructions for making the proper settings for charging a battery.
Whenyoufirststartchargingabattery,theampreadingwillbehigh.
As the battery becomes charged, the reading will decrease. To determine the amount of amps being drawn by the battery:
1.Press the Select Display Mode button until the AMPS LED lights.
a.When the 55A setting is used, the charger switches between 55A boost mode and 10A mode. You should use a lower charge setting if the voltage reading is “OL” or is reading higher than 14.2 Volts for more than 3 minutes.
b.When charging at 20 amps, the display should show 15 amps for a discharged battery and 7-8 amps for a fully charged battery. You should stop charging the battery at this time.
c.At the 2 amp charge rate, little or no display change will occur.
Note: The digital display will read OL or Overload if more than 55 amps are supplied to the battery. Overload means too high a charging rate. Lower the charging rate to continue.
To determine an accurate reading of your battery’s voltage before you charge:
1.Plug the power cord into a 3-prong electrical wall outlet.
2.Press the select Display Mode button so the VOLTAGE LED lights.
3.Connect the battery charger as outlined in “Charging Your Battery” on page 3. The voltage will be displayed.
Note: If a battery has recently been charged or in a vehicle that has been run recently, turn on the vehicle’s headlights for a few minutes before reading the meter to avoid getting a false reading from a surface charge.
4.Turn off vehicle’s headlights and read the digital display.
5.To turn OFF the charger, unplug the power cord from the AC wall outlet.
6.Disconnect the battery charging clamps as outlined in
“Charging Your Battery” on page 3.
H. ENGINE START

5.After the engine starts, unplug the charger power cord from the wall outlet.
6.Disconnect the output clamps from the battery.
7.Clean and store the charger in a dry location.
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, 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.
I.CHARGE PERIOD
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.

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:
Ampere 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 time needed for a charge:
•Find the percent of charge needed. (A battery at 50 percent charge that will be charged to 100 percent needs another 50 percent (.50).
•Multiply the Amp Hour rating by the charge needed (.50) and divide by the charger setting (2/20/55 amps).
•Multiply the result by 1.25 and you’ll have the time needed, in
hours, to bring the battery to full charge.
• Add one additional hour for a deep-cycle battery. Example:
Amp Hour Rating x % of charge needed x 1.25 |

The Chart Method
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 into the chart.
•Small batteries — motorcycles, garden tractors, etc. — are usually rated in Ampere Hours (AH). For example: 6 to 12 AH, or 12 to 32 AH.
•Batteries in cars and smaller trucks are usually rated in Reserve
Capacity (RC), Cold-Cranking Amps (CCA), or both.
•Marine, or deep-cycle batteries are usually rated in Reserve
Capacity (RC).
•NR means that the charger setting is NOT RECOMMENDED.
Find your battery’s rating on the chart on page 6 and note the charge time given for each charger setting. The times given are for batteries with a 50-percent charge prior to recharging. Add more time for severely discharged batteries.
