It might spark or short circuit the battery or other electrical part that may
cause an explosion.
2.7 Before working with a lead acid battery, remove personal metal items
such as rings, bracelets, necklaces, watches, etc. A lead acid battery can
produce a short circuit current high enough to weld such items, causing a
severe burn.
3. PREPARING TO CHARGE BATTERY
3.1 If necessary to remove the battery from the vehicle to charge, always
remove the grounded terminal from battery rst. Make sure all accessories
in the vehicle are off to prevent a possible arc.
3.2 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.
3.3 Clean the battery terminals. Be careful to keep corrosion from coming into
contact with your eyes.
3.4 Add distilled water in each cell until the battery electrolyte reaches the
level specied by manufacturer. This helps purge excessive gas from
cells. Do not overll. For a battery without caps, carefully follow the
manufacturer’s recharging instructions.
3.5 Study all battery manufacturer’s specic precautions, such as removing or
not removing cell caps while charging, and recommended rates of charge.
3.6 Determine voltage of the battery by referring to the vehicle owner’s
manual, and make sure that the output voltage selector switch is set at the
correct voltage. If the charger has an adjustable charge rate, charge the
battery initially at lowest rate. If the charger has only one voltage, verify
that the battery voltage matches the voltage of charger. For a charger
not having an output voltage selector switch, determine the voltage of
the battery by referring to the vehicle owner’s manual and make sure it
matches the output rating of the battery charger.

disconnected from the electrical outlet before you connect and disconnect
the charger clamps. Never allow the clamps to touch each other.
6.2 Attach clamps to battery posts and twist or rock back and forth several
times to make a good connection. This will tend to prevent the clamps
from slipping off terminals, avoid dangerous sparking, and assure safer
and more efcient charging. Keep the clamps clean.
CAUTION: SETTING SWITCHES TO OFF (O) DOES NOT ALWAYS
DISCONNECT THE CHARGER ELECTRICAL CIRCUIT FROM THE AC
POWER CORD OR DC CHARGER CLAMPS.
7. CHARGING BATTERY IN VEHICLE OR EQUIPMENT, OR CONNECTED
TO ENGINE
7.1 Before working on the vehicle, rmly apply the emergency brake and place
the gearshift to NEUTRAL. Shift an automatic transmission to PARK.
7.2 Locate the charger as far away from the battery as the charger cords
permit, and position the AC and DC cords to avoid stepping on or tripping
over them and to prevent damage by hood, doors, or moving engine parts.
7.3 Stay clear of fan blades, belts, pulleys, and any other parts that can cause
physical injury.
7.4 Turn OFF all vehicle loads, including door lights, and correct any defects
in vehicle’s electrical system that may have caused low battery.
7.5 Check the polarity of battery posts. The POSITIVE (POS., P, +) post
usually has larger diameter than NEGATIVE (NEG., N,–) post.
7.6 Determine which post of the battery is grounded (connected) to the
chassis. If the negative post is grounded (as in most vehicles), see
paragraph 7.7. If the positive post is grounded, see paragraph 7.8.
7.7 For a negative-grounded vehicle, rst connect the POSITIVE (red)
clamp from the charger to the POSITIVE (POS., P, +) ungrounded post
of battery. Then connect the NEGATIVE (BLACK) clamp to vehicle
chassis or engine block away from battery. Do not connect the clamp to
the carburetor, fuel lines, or sheet-metal body parts. Connect to a heavygauge metal part of the frame or engine block. When disconnecting the
charger, turn the switch to OFF (O), disconnect the AC cord, remove the
clamp from the vehicle chassis, and then remove the clamp from the
battery terminal.
7.8 For a positive-grounded vehicle, connect the NEGATIVE (BLACK) clamp
from the charger to the NEGATIVE (NEG., N, –) ungrounded post of the
battery. Then connect the POSITIVE (RED) clamp to the vehicle chassis
or engine block away from the battery. Do not connect the clamp to the
carburetor, fuel lines, or sheet-metal body parts. Connect to a heavygauge metal part of the frame or engine block.
• 6 •
When disconnecting the charger, turn the switch to OFF (O), disconnect
the AC cord, remove the clamp from the vehicle chassis, and then remove
the clamp from the battery terminal.
CAUTION: WHEN THE POSITIVE (+) POST OF THE VEHICLE
BATTERY IS GROUNDED, DOUBLE-CHECK POLARITY.
8. CHARGING BATTERY OUTSIDE VEHICLE OR EQUIPMENT–NOT
CONNECTED TO ENGINE
If necessary to remove the battery from the vehicle or equipment, always
remove the grounded terminal from the battery rst.
WARNING: MAKE SURE ALL VEHICLE LOADS ARE OFF TO PREVENT
A POSSIBLE ARC.
FOLLOW THESE STEPS WHEN THE BATTERY IS OUTSIDE THE
VEHICLE. A SPARK NEAR BATTERY MAY CAUSE AN EXPLOSION. TO
REDUCE RISK:
8.1 Check the polarity of the battery posts. The POSITIVE (POS., P, +) post
usually has a larger diameter than the NEGATIVE (NEG., N, –) post.
8.2 Attach an insulated battery cable that is at least a 24-inch, 6-gauge to the
NEGATIVE (NEG., N, –) battery post.
8.3 Connect the POSITIVE (RED) charger clamp to the POSITIVE (POS.,
P, +) post of the battery.
8.4 Position yourself and the free end of cable as far away from the battery as
possible. Do not face the battery when making the nal connection. Then
connect the NEGATIVE (BLACK) charger clamp to the free end of the
cable.
8.5 When disconnecting the charger, always do so in the reverse sequence of
the connecting procedure. Break the rst connection while staying as far
away from the battery as practical.
8.6. A marine (boat) battery must be removed and charged on shore. To
charge it on board requires equipment specially designed for marine use.
• 7 •
9. ELECTRICAL CONDITION OF BATTERY
9.1 The state of charge of rellable-top batteries can be checked by using
a hydrometer. A hydrometer is a bulb-type syringe which is used to
extract a small quantity of the electrolyte from each battery cell. Types
are calibrated in terms of specic gravity (a common scale being 1.120
to 1.265) or the type which uses four colored balls to indicate the state of
charge. A oat in the hydrometer barrel indicates the specic gravity of
the electrolyte. This specic gravity reading indicates the battery’s state of
charge at a given temperature, as shown in the table below:
State of Charge of
Battery at 80°F (27°C)
100% 1.280 1.265 1.225 4
75% 1.240 1.225 1.185 3

9.2 The state of charge of sealed-top (maintenance-free and recombinationtype) batteries must be checked with a high resolution voltage tester.
9.3 If uncertain about type of battery you will be charging, or the correct
procedure for checking the battery’s state of charge, contact the seller or
manufacturer of the battery.
9.4 The temperature of the battery and the equipment the battery is used
with has a dramatic effect on battery efciency and system power
requirements. For example, at 0°F (–18°C ), a battery is operating at 40%
of its rated efciency, while the engine it is attempting to start requires
over twice as much power as would be necessary at 80°F (27°C).

10. BATTERY CHARGING
10.1 This charger adjusts the charging time in order to charge the battery
completely, efciently and safely. However, this section includes
guidelines that can be used to estimate charging times.
10.2 The amount of time required to fully charge a weak battery is dependant
on a number of factors. In addition to the degree of discharge, these
factors include the type and rated capacity, temperature, age of the
battery, and amperage rating of the charger. At 70°F (22°C) the average
discharged battery will be recharged as follows.

Charging times will vary with battery type and condition.
•
10.3 Battery State – If a battery has only been slightly discharged, it can be
charged in less than a few hours. The same battery could take up to 10
hours if very weak. The battery state can be estimated by using the built-in
tester. The lower the reading the longer charging will take.
10.4. Battery rating – A higher rated battery will take longer to charge than
a lower rated battery under the same conditions. A battery is rated in
ampere-hours (AH), reserve capacity (RC) and cold cranking amps (CCA).
The lower the rating the quicker the battery will be charged.
• 9 •
10.5 CAUTION - Do not leave Manual chargers unattended.
10.6 CAUTION: If at any time the battery gets hot (above 125°F (52°C)) or acid
comes out of vent caps, STOP charging.
10.7 To maximize battery life - Let automatic chargers complete charging.
11. MULTIPLE BATTERY CHARGING
Batteries of the same voltage may be connected in parallel for
maintenance charging. Charge time increases in proportion to the number
of batteries. Rate of charge decreases in the same proportion.
Example: Charging 2 batteries in parallel will take 2 times longer; each
battery receives 1/2 the amount of charge showing on the ammeter. Thus,
if the ammeter shows a 30-amp charge, each battery will get a 15-amp
charge (when batteries have the same rating, same state of charge, etc.).
12. CHARGER FEATURES AND CONTROLS
12.1 BATTERY SIZE SWITCH
Use this switch button to set the battery size to one of the following:
2A SMALL: Intended for charging small batteries such as those
commonly used in garden tractors, snow mobiles and motorcycles. The
2A rate is not intended to be used as a trickle charger for larger batteries.
6A MEDIUM or 10A LARGE: Use for charging automotive batteries,
marine batteries, and deep cycle batteries. Not intended for industrial
applications.
12.2 BATTERY TYPE SWITCH
Use this switch button to set the type of battery to be charged to one of
the following.
• 10 •
STANDARD: Use on typical lead-acid batteries (starting and deep
•
cycle). This type of battery is usually used in boats, cars, trucks, and
motorcycles. These batteries have vent caps and are often marked “low
maintenance” or “maintenance-free”.
AGM: Use on batteries marked AGM (starting or deep cycle). AGM
•
batteries have sealed cases without vent caps.
GEL CELL: Use on batteries marked GEL CELL (starting or deep
•
cycle). Safe to use on “ALL” batteries.
With the exception of AGM and GEL CELL batteries, all other battery
types may or may not have vent caps. Ventcapsarelocatedontopofthe
batteryandprovideameanstoadddistilledwaterwhenneeded. 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. If the battery type is
unknown, use the GEL CELL setting.
12.3 OVERVIEW
Using the battery charger is very simple. First, connect the battery
and AC power following the precautions listed under “OPERATING
INSTRUCTIONS”. Then select the appropriate BATTERY TYPE and
BATTERY SIZE for your battery. The Charger will then do everything
automatically. This section explains a few details.
12.4 CHARGING
If the charger does not detect a properly connected battery, the
✓BATTERY will light continuously until a battery is detected. Charging
will not begin while the ✓BATTERY light is on. When charging begins, the
“CHARGING” LED will be lit.
12.5 AUTOMATIC SHUT OFF
When the 2A, 6A, or 10A battery type is selected, the charger is set to
perform an automatic charge, stops charging after the battery is fully
charged.
12.6 ABORTED CHARGE
If charging can’t be completed normally, charging will be aborted.
When charging is aborted, the charger’s output is shut off and the red
✓ BATTERY LED blinks on and off. In that state, the charger ignores
all buttons. To reset the charger from after an aborted charge, either
disconnect the battery or unplug the charger.
12.7 DESULFATION MODE
If a battery is left discharged for an extended period, it could become
sulfated and not accept a normal charge. If the charger detects a sulfated
battery, the charger will switch to a special mode of operation designed for
such batteries. Activation of the special desulfation mode is indicated by
blinking the CHARGING LED. If successful, normal charging will resume
after the battery is desulfated. The CHARGING LED will then stop blinking
and light continuously. Desulfation could take up to 10 hours. If desulfation
fails, charging will be aborted and the ✓BATTERY will blink.
• 11 •
12.8 COMPLETION OF CHARGING
Charge completion is indicated by the CHARGED (green) LED; when lit,
the charger has stopped charging and switched to the Maintain Mode of
operation.
12.9 MAINTAIN MODE
When the CHARGED (green) LED is lit, the charger has started Maintain
Mode. This mode of operation is also known as Float-Mode Monitoring.
In this mode, the charger keeps the battery fully charged by delivering
