Congratulations on purchasing the finest new charger on
the market today. We wish to acknowledge UL for their
contribution of the following important safety precautions.
Please read and retain these instructions for the continued
safe use of your new charger.
1. SAVE THESE INSTRUCTIONS – This manual contains
important safety and operating instructions for models
87102, 87104, 87105, 87106, 87120, 87121, 87122,
87128, 87150, 87151, & 87302.
6. Do not operate charger with damaged cord or plug.
Replace the cord or plug immediately.
7. Do not operate charger if it has received a sharp blow,
been dropped, or otherwise damaged in any way; take it
to a qualified service center. Call (866) 236-0044 and ask
for the location of a service center near you.
2. Intended for indoor use only.
Do not expose to rain or snow.
3. Use of an attachment not recommended or sold by Lin-
coln Electric may result in a risk of fire, electric shock,
or injury to persons.
4. To reduce risk of damage to electric plug and cord, pull
by plug rather than cord when disconnecting charger.
5. An extension cord should not be used unless
absolutely necessary. Use of improper extension cord
could result in a risk of fire and electric shock. If exten-
sion cord must be used, make sure:
a. That pins on plug of extension cord are the same
number, size, and shape as those of plug on char-
ger,
b. That extension cord is properly wired and in good
electrical condition; and
c. That the wire size is large enough for the length of
cord as specified below.
Length of cord in feet: 25 50 100 150
AWG size of cord: 18 18 16 14
8. Do not disassemble charger; take it to a qualified service
center when service or repair is required. Incorrect reas-
sembly may result in a risk of electric shock or fire.
9. To reduce risk of electric shock, unplug the charger from
outlet before attempting any maintenance or cleaning.
Turning off controls will not reduce this risk.
10. Monitor battery charger daily when using it to maintain
battery for extended periods (automatic models only).
11. WARNING – RISK OF EXPLOSIVE GASES.
a. Working in vicinity of a lead-acid battery is
dangerous. Batteries generate explosive gases dur-
ing 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 instruc-
tions exactly.
b. To reduce 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 vicinity of the battery. Review
cautionary marking on these products and in the
engine compartment.
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 bat-
tery 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 other jewelry 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 bat-
teries may burst and cause injury to persons and dam-
age to property.
9. NEVER charge a frozen battery.
1 Form No. 842-240-000 Rev. C 6/08
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 with a mixture of baking soda
and hot water. 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 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 specific gravity or filling the battery.
4. Do not operate the charger in a closed area or restrict
ventilation in any way.
5. Do not set a battery on top of the charger.
6. Locate the charger at least 18" above the floor.
7. Do not place the charger where rain, snow, or other
moisture could drip on it.
1. CAUTION: Connect and disconnect dc output clips
only after setting any switches with an OFF
position to off and removing ac power 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.
Charger should be grounded to reduce risk of electric
shock. Charger is equipped with an electric cord having an
equipment-grounding conductor and grounding plug. The
plug must be plugged into an outlet that is properly
installed and grounded in accordance with all local codes
and ordinances.
DANGER – Never alter ac cord or plug provided – if it
will not fit outlet, have proper outlet installed by a
qualified electrician. Improper connection can result in
a risk of an electric shock.
CAUTION: A MARINE (BOAT) BATTERY MUST BE
REMOVED AND CHARGED ON SHORE. TO CHARGE
IT ON BOARD REQUIRES EQUIPMENT SPECIALLY
DESIGNED FOR MARINE USE.
CAUTION: A SPARK NEAR BATTERY MAY CAUSE
BATTERY EXPLOSION. TO REDUCE RISK OF A
SPARK NEAR BATTERY:
1. Position ac and dc cords to reduce 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 polarity of battery posts. POSITIVE
(POS, P, +) battery post usually has larger diameter
than NEGATIVE (NEG, N, –) post.

The ammeter built into this charger indicates the
amperage that the battery is drawing from the charger.
The meter will read 15 amps if the battery is discharged
and the charger is set on the 12 volt 10, 12, or 15 amp
setting. As the battery charges, the meter will taper back to
around 7 amps. A charger with AUTO ON-OFF
TECHNOLOGY will drop to zero amps and the CHARGE
COMPLETE light will come on when the battery is fully
charged. On the 12 volt 2 amp setting the meter will read
5 amps for a discharged battery and taper back to about ό
amp as it charges.
The 6 volt setting is a constant current setting and the
needle will not move from right to left (not applicable to the
87122).
The BATTERY area in red at the top of the meter should
not be used as a precise measurement of the battery’s
percent of charge. There are differences between charger
models and from battery to battery that prevent it from
accurately representing the actual percent of charge.
Chargers with AUTO ON-OFF TECHNOLOGY will show
100% when fully charged.

Manual battery chargers need to be disconnected from a
battery when the battery is fully charged. If this is not
done, the battery will overcharge, resulting in possible
battery damage.
A large automotive battery (65 amp hours or 100 minutes
of reserve capacity) that is completely discharged (lights
will not come on at all) should never take longer than 8
hours to charge on the 12 volt 10 amp setting. Batteries
with a partial charge, smaller batteries, and chargers with
a higher amperage output such as 12 or 15 amps will take
even less time to charge. If the meter shows that the
battery is drawing amperage (from 7–15 amps) and after
charging for up to eight hours, the battery still isn’t fully
charged, have the battery professionally tested or
replaced. On battery chargers equipped with AUTO ON-
OFF TECHNOLOGY, if the meter shows zero amps, then
preactivation of the battery may be required.
The following instructions will allow you to determine how
long it will take to bring a specific battery to full charge. If
the charger is so equipped, a green light on the charger
will indicate the battery has become fully charged.
CAUTION
Batteries that have 25% charge or less can easily freeze
and should be charged at once, but DO NOT CHARGE A
BATTERY THAT IS ALREADY FROZEN.
1. Determine the present level of charge in the battery
with a hydrometer or electronic percent-of-charge
tester.
2. Determine the size of the battery in AMP HOURS or
RESERVE CAPACITY. If these ratings are not printed
on the battery, contact your local battery dealer for this
information. These are the only ratings that can be
used to determine length of charging time. Then use
the formula in step 3 for the charging rate capabilities
of your charger.
3. Use the battery rating, the charge level of the battery,
and the amp setting to be used on the charger, in the
formula provided below.
NOTE: If the battery is rated in RESERVE CAPACITY,
use the following formula to convert reserve capacity to
amp-hours.
