WARNING – RISK OF EXPLOSIVE GASES

1. 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 EACH TIME BEFORE USING YOUR CHARGER, YOU READ THIS MANUAL AND FOLLOW THE INSTRUCTIONS EXACTLY.
2. To reduce the risk of battery explosion, follow these instructions and those published by battery manufacturers and manufacturers of any equipment you intend to use in the vicinity of the battery. Review cautionary markings on these products and on the engine.

PERSONAL PRECAUTIONS

1. Someone should be within range of your voice or close enough to come to your aid when you work near a lead-acid battery.
2. Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing or eyes.
3. Wear complete eye protection and clothing protection. Avoid touching your eyes while working near the battery.
4. If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters eye, immediately flood eye with running cold water for at least 10 minutes and get medical attention immediately.
5. NEVER smoke or allow a spark or flame in the vicinity of the battery or engine.
6. Be extra cautious to reduce the risk of dropping a metal tool onto the battery. It might spark or short-circuit the battery or another electrical part may cause an explosion.
7. Remove 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 severe bum. Use a charger for charging a LEAD-ACID battery only.
8. It is not intended to supply power to a low-voltage electrical system other than in an automotive application. Do not use a 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.
9. NEVER charge a frozen battery

PREPARING TO CHARGE

1. If necessary to remove the battery from the vehicle to charge, always remove the grounded terminal from the battery first. Make sure all accessories in the vehicle are off, so as not to cause an arc.
2. Be sure the area around the battery is well-ventilated while the battery is being charged. Gas can be forcefully blown away by using a piece of cardboard or other nonmetallic material as a fan.
3. Clean battery terminals. Be careful to keep corrosion from coming in contact with eyes.
4. Add distilled water in each cell until battery acid reaches level specified by the battery manufacturer. This helps purge excessive gas from cells. Do not overfill. For a battery without cell caps, carefully follow the manufacturer’s recharging instructions.
5. Study all battery manufacturer’s specific precautions such as removing or not removing cell caps while charging and recommended rates or charge.
6. Determine the voltage of the battery by referring to the car owner’s manual and make sure that the output voltage selector switch is set as the correct voltage. If the charger has an adjustable charge rate, charge the battery initially at the lowest rate.

CHARGER LOCATION

1. Locate the charger as far away from the battery as DC cables permit.
2. Never place the charger directly above the battery being charged; gases from the battery will corrode and damage the charger.
3. Never allow battery acid to drip on the charger when reading gravity or filling the battery.
4. ventilation in any way.
5. Do not set a battery on top of the charger.
6. Do not expose the charger to rain or snow.
7. Do have proper ventilation. Air needs to flow around the entire charger.

READING METER/LECTURA DEL MEDIDOR

DC CONNECTION PRECAUTIONS

1. Connect and disconnect DC output clips only after setting any charger switches to the 2 AMP position and then removing the AC cord from the electric outlet. Never allow clips to touch each other.
2. Attach clips to battery posts and twist or rock back and forth several times to make good connections This tends to keep clips from slipping off terminals and helps to reduce the risk of sparking.

FOLLOW THESE STEPS WHEN THE BATTERY IS INSTALLED IN THE VEHICLE IF A SPARK NEAR THE BATTERY MAY CAUSE A BATTERY EXPLOSION TO REDUCE RISK OF SPARK NEAR BATTERY:

1. Position AC and DC cords to reduce the risk of damage by hood, door, or moving engine part.
2. Stay clear of fan blades, belts, pulleys, and other parts that can cause injury to persons.
3. Check the polarity of battery posts. POSITIVE (POS, P,+) battery post usually has a larger diameter than NEGATIVE (NEG, N, -) post.
4. Determine which post of the battery is grounded (connected to the chassis). If the negative post is grounded to the chassis (as in most vehicles), see No.5 If the positive post is grounded to the chassis, see No. 6.
5. For a negative-grounded vehicle, connect the POSITIVE (RED) clip from the battery charger to the POSITIVE (POS, P,+) ungrounded post of the battery. Connect a 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.
6.  For a positive-grounded vehicle, connect the NEGATIVE (BLACK) clip from the battery charger to the NEGATIVE (NEG, N, -) ungrounded post of the battery. Connect a POSITIVE (RED) clip to the vehicle chassis or engine block away from the battery. Do not connect clips to the carburetor, fuel lines, or sheet metal body parts. Connect to a heavy gauge metal part of the frame or engine block.
7. When disconnecting the charger, disconnect the AC cord,\ Remove the clip from the vehicle chassis, and then remove the clip from the battery terminal, in that order.
8. See charge period for length of charge information.

AC POWER CORD CONNECTION INSTRUCTIONS

DANGER – Never alter the AC cord or plug provided – if it will not fit the outlet, have a proper outlet installed by a qualified electrician. Improper connection can result in a risk of an electric shock. This battery charger is for use on a nominal 120-volt 60 HZ circuit

OPERATION INSTRUCTIONS

1. These battery chargers are equipped with a self-resetting circuit breaker. This device protects the charger from temporary overloads. In the event of an overload, the circuit breaker will trip open and after a short cooling-off period will reset automatically. this process is known as cycling and can be recognized by an audible clicking sound
2. These battery chargers are equipped with an electronic control circuit that automatically governs the charge rate to your battery. The charger will satisfactorily charge Maintenance and Conventional batteries

OUTPUT VOLTAGE
These chargers are for use with 12-volt lead-acid batteries only.

CHARGE RATE SWITCH
For smaller batteries, 30 AH (ampere hour) or less, use a 2 AMP setting. Small batteries may not be able to accept the potential of the 10 or 12-AMP setting. Unconverted energy will result in excess heat which the battery may not be able to dissipate, thus resulting in damage to the battery. For larger batteries either setting may be used

INDICATION OF PROPER OPERATION TO A DISCHARGED
BATTERY BUT OTHERWISE IN GOOD CONDITION

12 AMP setting: The initial charge current should be 12 AMPs gradually taper throughout the charge cycle to 5 Amps. Though not indicated, the battery voltage will gradually rise to approximately 15 volts, then hold constant throughout the remainder of the charge cycle. When the battery reaches 15 volts and the charge current drops to 5 AMPs the charger will turn off. Initially, the battery voltage will drop from its 15-volt level fairly quickly When 13 volts is reached, the charger will again turn on, until the 15 volt, 5 AMP condition is met. As this action continues, ON time will decrease to a few seconds while OFF time increases to a range of several minutes to an hour. ON/OFF times vary with the size, type, and condition of the battery. 2. 2 AMP setting ON/OFF action is a function of the battery voltage only, otherwise identical to the 12 AMP setting.

CHARGE PERIOD
The approximate required time to bring a battery to full charge state depends upon the number of ampere-hours (AH) depleted from the battery. AHs are determined by multiplying the number of hours by the number of AMPS supplied to a load. For example – If a load was connected to a battery, which drew 7 AMPS for a period of 5 hours, the battery will have supplied 35 AH. The approximate recharge time would then be calculated by dividing the 35 AH depleted from the battery, by the ampere charge rate of the charger. To allow for tapering off of the charge rate, add 25 percent to the charge time. Indications of a fully charged battery are:

1. When the meter indicates an intermittent current flow to the battery.

2. A hydrometer reading of the specific gravity of the electrolyte (fluid) of a battery in good condition should be between 1.250 and 1.285.

3. When a battery reaches 80-85% of full charge, bubbles will appear on the surface of the fluid. As the battery nears full charge, bubbling will become more noticeably active.

4. The time required to charge two 6-volt batteries connected in series will be the same as for one 12-volt battery of equivalent size.
   NOTE: This charger will shut off when the battery is fully charged and will turn back on automatically when the battery needs to be charged again.

5. Do not charge two 12-volt batteries in parallel.

STORAGE

Store the battery charger in a dry area.
