OWNER’S MANUAL

IMPORTANT SAFETY INSTRUCTIONS - READ THESE FIRST

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 eyes while working near 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 vicinity of
battery or engine.

6. Be extra cautious to reduce risk of dropping a metal
tool onto battery. It might spark or short-circuit battery
or other electrical part that may cause 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 a severe burn.

8. Use charger for charging LEAD-ACID battery only. It
is not intended to supply power to a low voltage
electrical system other than in a starter-motor
application. Do not use 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.

1. If necessary to remove battery from vehicle to charge,
always remove grounded terminal from battery first.
Make sure all accessories in the vehicle are off, so as
not to cause an arc.

2. Be sure area around battery is well ventilated while
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 battery manufacturer. This
helps purge excessive gas from cells. Do not overfill.
For a battery without cell caps, carefully follow
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 of charge.

6. Determine voltage of battery by referring to car
owner’s manual and make sure that output voltage
selector switch is set at correct voltage.

1 Locate charger as far away from battery as dc cables

permit.

2. Never place charger directly above battery being
charged; gases from battery will corrode and damage
charger.

3. Never allow battery acid to drip on charger when
reading gravity or filling battery.

4. Do not operate charger in a closed area or restrict
ventilation in any way.

5. Do not set a battery on top of charger.

6. Locate charger at least 18” above the floor.

1. CAUTION: Connect and disconnect dc output

clips only after setting any switches with an “off”
position to off and removing AC cord from electric
outlet. Never allow clips to touch each other.

2. When hooking up charger, attach one clip to battery
and the other to a point away from battery (see
sections “G” & “H”). Do not hook up charger until
reading sections A-J.

To reduce explosion risk, never connect both clips
directly to the battery. When making each connection,

twist or rock clip back and forth several times to make a
good connection and to reduce the risk of a clip slipping
off and creating a spark. Do not twist or rock clip on

the battery after the second clip connection is made.

When in the one of the automatic shut-off modes, the

charger‘s output will shut off when the proper voltage is

reached. You should monitor the charging process at least

daily to ensure that the battery’s electrolyte level is proper

and that the battery does not over charge. When the

charger’s output does shut off, the green “Charge

Complete” light comes on. The transformer of the charger

is still on so it is normal to hear a humming or buzzing

noise as the charger continues to monitor the battery
charge level. If the green “Charge Complete” light does
not come on at least once in a day’s charging, set the
“Select Setting” switch to “Start” (“Activate” on 87122). If
the green “Charge Complete” light does not come on
within 30 minutes, discontinue charging and read section

READING THE METER & TIME TO CHARGE

L

The ammeter built into this charger indicates the
amperage that the battery is drawing from the charger.
The meter will read the maximum output rating of the
charge setting selected only if the battery being charged is
fully discharged.

The “Battery” area in red at the top of the meter gives an
approximation of the battery’s state of charge. The needle
will move from right to left as the battery approaches full
charge (12 volt only).

When set to an Automatic Shut-off position (the “Select
Function” switch is in the “Charge” position and the “Select
Setting” switch is in one of the 12 volt positions), the
battery charger will automatically shut off when the battery
has been fully charged.

The 6 volt setting is a constant current setting and the
needle will not move from right to left (not applicable to the

CHARGER CARE & MAINTENANCE

CAUTION - Make sure charger is unplugged from AC
outlet before performing any maintenance.

A minimum amount of care can keep your battery charger
working and looking good for years.

1. Clean the clamps after each use. Wipe off any battery
fluid that may have come in contact with the clamps to
prevent corrosion. Battery fluid may be neutralized
with a solution of water and baking soda.

2. Coil the input and output cables neatly around the
cable wrap/handle, on the top of the charger after

each use. This will help prevent damage to the cables
and the charger.

3. If needed, the case may be wiped clean with a soft
cloth.

Any other service to this battery charger must be done by
a qualified repair facility. There are no user-serviceable
parts inside.
