WARNING – RISK OF EXPLOSIVE GASES.
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.
• 1 •
TO REDUCE THE RISK OF 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.
PERSONAL PRECAUTIONS2.
Consider having someone close enough by to come to your aid when you 2.1
work near a lead-acid battery.
Have plenty of fresh water and soap nearby in case battery acid contacts 2.2
your skin, clothing or eyes.
Wear complete eye protection and clothing protection. Avoid touching your 2.3
eyes while working near the battery.
If battery acid contacts your skin or clothing, wash immediately with soap 2.4
and water. If acid enters your eye, immediately ood the eye with cold running water for at least 10 minutes and get medical attention immediately.
NEVER smoke or allow a spark or ame in the vicinity of a battery or 2.5
engine.
Be extra cautious to reduce the risk of dropping a metal tool onto the bat-2.6
tery. It might spark or short-circuit the battery or other electrical part that
may cause an explosion.
Remove personal metal items such as rings, bracelets, necklaces and 2.7
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.
Use this charger for charging a LEAD-ACID battery only. It is not intended 2.8
to supply power to a low voltage electrical system other than in a startermotor 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.2.9
NEVER overcharge a battery.2.10
PREPARING TO CHARGE3.
If it is necessary to remove the battery from the vehicle to charge it, al-3.1
ways remove the grounded terminal from the battery rst. Make sure all of
the accessories in the vehicle are off, so as not to cause an arc.
Be sure the area around the battery is well ventilated while the battery is 3.2
being charged.
• 2 •
Clean the battery terminals before charging the battery. During cleaning, 3.3
keep 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 3.4
specied by the battery manufacturer. Do not overll. For a battery without
removable cell caps, such as valve regulated lead-acid batteries, carefully
follow the manufacturer’s recharging instructions.
Study all of the battery manufacturer’s specic precautions while charging 3.5
and recommended rates of charge.
Determine the voltage of the battery by referring to the vehicle owner’s 3.6
manual 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 rst.
CHARGER LOCATION4.
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 4.2
from the battery will corrode and damage the charger.
Never allow battery acid to drip onto the charger when reading the electro-4.3
lyte specic gravity or lling the battery.
Do not operate the charger in a closed-in area or restrict the ventilation in 4.4
any way.
Do not set a battery on top of the charger.4.5
DC CONNECTION PRECAUTIONS5.
Connect and disconnect the DC output clips only after setting all of the 5.1
charger 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, 5.2
and 7.2 thru 7.4.
FOLLOW THESE STEPS WHEN BATTERY IS INSTALLED IN 6.
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, 6.1
door, or moving engine parts.
Stay clear of fan blades, belts, pulleys and other parts that can cause 6.2
injury.
Check the polarity of the battery posts. The POSITIVE (POS, P, +) battery 6.3
post usually has a larger diameter than the NEGATIVE (NEG, N, -) post.
• 3 •
Determine which post of the battery is grounded (connected) to the chas-6.4
sis. 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 6.5
the 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 6.6
from the 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 to off, disconnect the 6.7
AC cord, remove the clip from the vehicle chassis, and then remove the
clip from the battery terminal.
See OPERATING INSTRUCTIONS for length of charge information.6.8
FOLLOW THESE STEPS WHEN BATTERY IS OUTSIDE VEHICLE. 7.
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 7.1
post usually has a larger diameter than the NEGATIVE (NEG, N, -) post.
Attach at least a 24-inch-long 6-gauge (AWG) insulated battery cable to 7.2
the NEGATIVE (NEG, N, -) battery post.
Connect the POSITIVE (RED) charger clip to the POSITIVE (POS, P, +) 7.3
post of the battery.
Position yourself and the free end of the cable you previously attached to 7.4
the 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 nal connection.7.5
When disconnecting the charger, always do so in reverse sequence of 7.6
the connecting procedure and break the rst connection while as far away
from the battery as practical.
A marine (boat) battery must be removed and charged on shore. To 7.7
charge it onboard requires equipment specially designed for marine use.

DIGITAL DISPLAY BUTTON 10.1
Use this button to set the function of the digital display to one of the following:
BATTERY %:• The digital display shows an estimate of the percent of
charge of the battery connected to the charger battery clamps.
VOLTAGE: • The digital display shows the voltage at the charger battery
clamps in DC volts.
BATTERY TYPE BUTTON 10.2
Use this button to set the type of battery to be charged to one of the following:
Regular• – Set button to STANDARD. 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 composition. Regular batteries should
not be used for deep cycle applications
Deep-Cycle• – Set button to STANDARD. Deep-cycle batteries are usu-
ally 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• – Set button to STANDARD. The Absorbed Glass Matt construction
allows the electrolyte to be suspended in close proximity with the plate’s
active material. In theory, this enhances both the discharge and recharge
efciency. Actually, the AGM batteries are a variant of Sealed VRLA batteries. Popular usage high performance engine starting, power sports,
deep cycle, solar and storage battery. AGM batteries are typically good
• 6 •
deep cycle batteries and they deliver best life performance if recharged
before the battery drops below the 50 percent discharge rate. If these
AGM batteries are discharged to a rate of 100 percent the cycle life will
be 300 plus cycles and this is true of most AGM batteries rated as deep
cycle batteries.
GEL• – Set button to GEL CELL. 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 application 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 is certain.
Gel Cell and some AGM batteries may require a special charging rate.
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.
