A. IMPORTANT SAFETY INSTRUCTIONS
1. SAVE THESE INSTRUCTIONS - This manual contains important safety
and operating instructions for battery charger models.
MODELS: SE-40MAP, SE-50MA-2 and SE-3004
A BATTERY CHARGER RECEIVES AC POWER FROM THE ELECTRIC OUTLET AND
DELIVERS DC CURRENT TO THE BATTERY.
2. Before using battery charger, read all instructions and cautionary markings on (1) battery
charger, (2) battery and (3) product using battery.
3. CAUTION - To reduce risk of injury, charge only lead acid type rechargeable batteries.
Other types of batteries may burst causing personal injury and damage.
4. Use of an attachment not recommended or sold by the battery charger manufacturer may
result in a risk of fire, electric shock, or injury to persons.
5. To reduce risk of damage to electric plug and cord, pull by plug rather than cord when
disconnecting charger.
6. Make sure cord is located so that it will not be stepped on, tripped over, or otherwise
subjected to damage or stress.
7. 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 extension 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 charger.
(b) That extension cord is properly wired and in good electrical condition; and
(c) That wire size is large enough for AC ampere rating of charger as specified below:
AC INPUT RATING, AMPERES AWG SIZE OF CORD
Equal to or but less than Length of Cord, Feet
Greater than
0 2 18 18 18 16
2 3 18 18 16 14
3 4 18 18 16 14
8. Do not operate charger with damaged cord or plug - replace them immediately.
9. 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 man.
10. Do not disassemble charger; take it to a qualified serviceman when service or repair is
required. Incorrect reassembly may result in a risk of electric shock or fire.
11. To reduce risk of electric shock, unplug charger from outlet before attempting any maintenance or cleaning. Turning off controls will not reduce this risk.
B. WARNING - RISK OF EXPLOSIVE GASES
1. WORKING IN 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 EACH TIME BEFORE USING YOUR
CHARGER, YOU READ THIS MANUAL AND FOLLOW THE INSTRUCTION EXACTLY.
2. To reduce risk of battery explosion, follow these instructions and those published by
battery manufacturer and manufacturer of any equipment you intend to use in vicinity of
battery. Review cautionary marking on these products and on engine.
C. 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.
Call Customer Service if you have questions: 1-800-621-5485
25 50 100 150
00-99-000161/0103
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 metal tool onto battery. It might spark or shortcircuit 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 a LEAD-ACID battery only. It is not intended to supply power to
a low-voltage electrical system other than in an automotive 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.
10. WARNING: Handling the cord on this product or cords associated with accessories
sold with this product, will expose you to lead, a chemical known to the State of California to
cause cancer and birth defects or other reproductive harm.
D. PREPARING TO CHARGE
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 non-metallic 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
of charger is the same. If charger has adjustable charge rate, charge battery initially at
lowest rate.
E. CHARGER LOCATION
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 specific gravity or filling battery.
4. Do not operate charger in a closed-in area or restrict ventilation in any way.
5. Do not set a battery on top of charger.
6. Do not expose charger to rain or snow.
F. DC CONNECTION PRECAUTIONS
1. Connect and disconnect DC output clips only after seeing any charger switches to off
position and removing AC cord from electric outlet.
2. Attach clips to battery posts and twist or rock back and forth several times to make a good
connection. This tends to keep clips from slipping off terminals and helps to reduce risk of
sparking.
G. FOLLOW THESE STEPS WHEN BATTERY IS INSTALLED IN VEHICLE. A SPARK NEAR
BATTERY MAY CAUSE BATTERY EXPLOSION. TO REDUCE RISK OF SPARK
NEAR BATTERY:
1. Position AC and DC cords to reduce risk of damage by hood, door, or moving engine
parts.
Wash hands after handling.
2
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.
4. Determine which post of battery is grounded (connected) to the chassis. If negative post
is grounded to chassis (as in most vehicles), see #5. If positive post is grounded to the
chassis, see #6.
5. For negative-grounded vehicle, connect POSITIVE (RED) clip from battery charger to
POSITIVE (POS, P. +) ungrounded post of battery. Connect NEGATIVE (BLACK) clip to
vehicle chassis or engine block away from battery. Do not connect clip to carburetor, fuel
lines, or sheet-metal body parts. Connect to a heavy gage metal part of the frame or engine
block.
6. For positive-grounded vehicle connect NEGATIVE (BLACK) clip from battery charger to
NEGATIVE (NEG, N. -) ungrounded post of banery. Connect POSITIVE (RED) clip to
vehicle chassis or engine block away from battery. Do not connect clip to carburetor, fuel
lines, or sheet-metal body parts. Connect to a heavy gage metal part of the frame
or engine block.
7. When disconnecting charger, turn switches to off, disconnect AC cord, remove clip from
vehicle chassis, and then remove clip from battery terminal, in that order.
8. See operating instructions for length of charge information.
H. FOLLOW THESE STEPS WHEN BATTERY IS OUTSIDE VEHICLE. A SPARK NEAR
THE BATTERY MAY CAUSE BATTERY EXPLOSION. TO REDUCE RISK OF A SPARK
NEAR BATTERY:
1. Check polarity of battery posts. POSITIVE (POS, P. +) battery post usually has a larger
diameter than NEGATIVE (NEG, N. -) post.
2. attach at least a 24 inch-long 6-gauge (AWG) insulated battery cable to NEGATIVE
(NEG, N. -) battery post.
3. Connect POSITIVE (RED) charger clip to POSITIVE (POS, P. +) post of battery.
4. Position yourself and free end of cable as far away from battery as possible - then connect NEGATIVE (BLACK) charger clip to free end of cable.
5. Do not face battery when making final connection.
6. When disconnecting charger, always do so in reverse sequence of connecting procedure and break first connection while as far away from battery as practical.
7. A marine (boat) battery must be removed and charged on shore. To charge it on board
requires equipment specially designed for marine use.
I. GROUNDING AND AC POWER CORD CONNECTION INSTRUCTIONS
Charger should be grounded to reduce risk of electric shock. Charger is equipped with an
electric cord having an equipment-grounding conductor and a 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. This battery charger is for use on a nominal 120-volt circuit and has a grounding
plug that looks like the plug illustrated in sketch A in figure 1. A temporary adapter, which
looks like the adapter illustrated in sketches B and C, may be used to connect this plug to a
two-pole receptacle as shown in sketch B if a properly grounded outlet is not available. The
temporary adapter should be used only until a properly grounded outlet can be installed by
a qualified electrician.
DANGER - Before using adapter as illustrated, be certain that center screw of outlet plate
is grounded. The green colored rigid ear or lug extending from adapter must be connected
to a properly grounded outlet - make certain it is grounded. If necessary, replace original
outlet cover plate screw with a longer screw that will secure adapter ear or lug to outlet cover
plate and make ground connection to grounded outlet.
Use of an adapter is not allowed in Canada. If a grounding type receptacle is not available,
do not use this appliance until the proper outlet is installed by a qualified electrician.
