Remember:
•Place charger as far away from battery being
charged as the charger cables will permit.
•Do not expose charger to rain or snow.
•Never charge a frozen battery. If battery fluid
(electrolyte) becomes frozen, bring battery into a
warm area to thaw before you begin charging.
•Never allow battery acid to drip on charger when
reading specific gravity or filling battery.
•Never set a battery on top of the charger.
•Never place charger directly above battery being
charged. The gases from the battery will corrode
and damage the charger.
•Never use charger for charging dry-cell batteries
that are commonly used with home appliances.
These batteries may burst and cause personal
injury.
• Do not disassemble charger. Take it to a
qualified service professional if service or
repair is required. Incorrect assembly may
result in fire or electrical shock.
• To reduce risk of electrical shock, unplug
the charger from the outlet before attempting
any maintenance or cleaning.
• Always charge battery in a well ventilated
area.
•Never touch the battery clamps together when the
charger is energized.
•Never operate charger if it has received a hard blow,
been dropped, or otherwise damaged. Take it to a
qualified professional for inspection and repair.
•Be sure to position the charger power cord to
prevent it from being stepped on, tripped over, or
damaged.
•Never pull out the plug by the cord when unplug-
ging the charger. Pulling on the cord may cause
damage to the cord or the plug.
•Do not operate the charger if it has a damaged
power cord or plug. Have the cord replaced.
Personal Safety Precautions
For your own personal safety, please follow the
following precautions:
•Wear complete eye and clothing protection when
working with lead-acid batteries.
•Be sure that someone is within range of your
voice
to come to your aid if needed while you work
with or are near a lead-acid battery.
•Have plenty of fresh water and soap nearby for
use in case battery acid contacts your eyes, skin,
or cloth-ing. If this happens, wash immediately
with soap and water. Then get medical attention.
•Avoid touching your eyes while working with a
battery. Acid particles (corrosion) may get into
your eyes. If this occurs, flush eyes immediately
with running cold water for at least 10 minutes.
Then immediately get medical attention.
Sears 210 - Sch 50911/13/95
•Remove all personal metal items from your body,
such as rings, bracelets, necklaces, and watches
while working with a lead-acid battery. A battery can
produce a short circuit current high enough to weld
a ring (or the like) to metal, causing a severe burn.
•Take care not to drop any metal tool or metal object
onto the battery. This may spark or short circuit the
battery or another electrical device that may cause
an explosion.
•Always operate your battery charger in an open, well
ventilated area.
•Never smoke or allow a spark or flame in the vicinity
of the battery or engine. Batteries generate explosive
gases.
•Neutralize any acid spills thoroughly with baking
soda before attempting to clean up.

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
L! 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.
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.
DANGER: 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 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.
Using an extension cord
The use of an extension cord is not recommended. If
you must use an extension cord, please make sure
that you follow these guidelines:
•Make sure the pins on the plug of the extension cord
are the same number, size, and shape as those of the
plug on the charger.
•Use only 3-conductor (grounded) extension cord
when necessary.
•Check that the extension cord is properly wired and
in good electrical condition.
•Make sure that the wire size is large enough for its
length and for the AC ampere rating as specified in
the accompanying chart.

Preparing your battery to be charged
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.
• If you have a battery with removable cell caps, if
required, add distilled water to each cell until the
battery acid reaches the level recommended 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.
• 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.
• 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, gas 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.
NOTE: A marine battery installed in a boat must be
removed and charged on shore.

Setting the Controls
SELECTOR SWITCHES:
A 2-way switch is used to select the 2-AMP or the
10-AMP charge rate.
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 using
the 10 amp charging rate. As the battery charges, the needle
will fall to about 4 or 5 amps, indicating a charged battery.
At the 2 amp charging rate, as the battery charges the
needle will fall to about 3/4 to 1 amp indicating a charged
battery.
The percent of charge scale is intended as a visual aid to
help simplify reading the state of charge of the battery. The
meter is scaled for use with the 10 amp charge rate only.
For the 2 amp charge rate use the red triangle. The percent
of charge is based on current drawn by the battery. For this
reason accuracy will vary with the size and battery type.

10 AMP 2 AMP
Charging Your Battery
Charging a battery in the vehicle:
1. Arrange the power cord and charging leads carefully
to avoid damage that could be caused by the hood,
door, or moving engine parts.
2. Keep clear of fan blades, belts, pulleys, and other
parts that can cause injury.
3. 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.
4. Identify which battery post is ground 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, 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.

6. 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.
7. Select the charge rate with the Selector Switch then
plug the power cord into a grounded AC outlet to
begin charging.
8. The charger will not stop when the battery is fully
charged. For this reason it is important to check
charging progress frequently. Overcharging can
damage a battery, you must monitor and unplug
charger when battery is fully charged.
9. When the battery is fully charged, the AMMETER
pointer will fall to about half the charge rate selected.
For specific positions, refer to the "Ammeter" section
in “Using your battery charger" on page 6.
10. When the battery is fully charged, unplug the charger
power cord before attempting to disconnect charger
clamps.
11. Standing away from the battery, remove the charger
clamps in this order: (1) from the chassis
connection and, (2) from the battery post or terminal.
12. Clean and store the battery charger in a dry location.
Charging your battery outside the vehicle:
1. 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 post 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
occur away from 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 4-gauge
(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 rate of charge with the Selector Switch
then plug the power cord into a grounded AC outlet
to begin charging.
7. The charger will not stop when the battery is fully
charged. For this reason it is important to check
charging progress frequently. Overcharging can
damage a battery, you must monitor and unplug
charger when battery is fully charged.

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
RECOMMENED.
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 prior to recharging. Add more time for severely
discharged batteries.

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 or 10 amps).
• Multiply the result by 1.25 and you’ll have the
approximate 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 charge needed x 1.25 = hours

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 Capacity + 16

You would need to charge your 100-Ampere Hour Battery for approximately 6¼ hours at the 10-Amp charge
rate using the above example.
