BATTERY CHARGER & MAINTAINER 12VOLT  
Read rules  
for safe  
operation  
and  
instructions  
carefully.  
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 INSTRUCTIONS EXACTLY.  
GENERAL BATTERY SAFETY  
1. Before you use your battery charger, be sure to read all  
10. Do not use an extension cord unless absolutely necessary.  
instructions and cautions printed on:  
• Battery Charger  
Use of an improper extension cord could result in fire or electric  
shock. If an extension cord must be used, make sure that:  
• Battery  
• Vehicle or unit using battery  
• Pins on plug of extension cord are the same number, size, and  
shape as those of plug on charger.  
• Extension cord is properly wired and in good electrical  
condition.  
• Wire size is large enough for AC ampere rating of charger, as  
specified below:  
2. Use battery charger on LEAD ACID type rechargeable batteries  
only, such as used in autos, trucks, tractors, airplanes, vans, RV's  
trolling motors, etc. Charger is not intended to supply power to  
low-voltage electrical system other than in an automotive  
application.  
Length of cord (feet): 25 50 100 150  
WARNING: Do no use battery charger for charging drycell  
batteries that are commonly used with home appliances. These  
batteries may burst and cause injury to persons and damage to  
property.  
AWG size of cord:  
18 18 18  
16  
11. Always charge battery in a well ventilated area.  
NEVER operate in a closed-in or restricted area without adequate  
ventilation.  
WARNING: Risk of explosive gas.  
12. Locate charger as far away from battery as DC charger  
cables permit.  
13. Do not expose charger to rain or snow.  
14. NEVER charge a frozen battery. If battery fluid (electrolyte)  
is frozen, bring into a warm area to thaw before charging. 15.  
NEVER allow battery acid to drip on charger when reading  
specific gravity or filling battery.  
16. NEVER set a battery on top of charger.  
17. NEVER place charger directly above battery being charged.  
Gases from battery will corrode and damage charger.  
18. NEVER touch the battery clips together when the charger  
is energized.  
3. Use only attachments recommended or sold by manufacturer. Use  
of non-recommended attachments may result in fire, electric  
shock, or injury.  
4. When disconnecting the battery charger, pull by the plug not by  
the cord. Pulling on the cord may cause damage to cord or plug.  
5.  
Locate battery power cord so it cannot be stepped on,  
tripped over, or subjected to damage or stress.  
Do not operate charger with damaged cord or plug. Have  
cord replaced immediately.  
6.  
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  
professional for inspection and repair.  
8. Do not disassemble charger. Take it to a qualified professional  
when service or repair is required. Incorrect reassembly may  
result in electric shock or fire.  
19. NEVER crank engine with charger attached to battery, and  
120 volt line.  
9.  
To reduce risk of electric shock, unplug charger from outlet  
before attempting any maintenance or cleaning.

MOUNTING INSTRUCTION  
Figure 1 illustrates the charger mounting brackets.  
Figure 2 illustrates surface mounting of the charger to the  
Fender well. If using the nut and bolt provided, drill two holes between  
3/16" and 1/4" in diameter. (For alignment of holes use one of  
the brackets as a template.) If the backside of the mounting  
surface is hard to reach, you may consider using two 1/2" sheet  
metal screws instead of nut bolt, drill a pilot hole if required, drill  
holes between 1/8" and 5/32". CAUTION: Do not drill or puncture  
battery.  
Electrical installations - Route and secure supply cord and output wiring  
away from gas line, carburetor or other hot, sharp or moving and pinch  
parts to avoid damage to the insulation. Secure the AC cord and plug to  
a cable or from using a self locking cable tie or equivalent.  
Figure No. 3 illustrates mounting of the charger alongside the battery of  
your automobile. If convenient place the charger to the side of the  
battery away from the engine and fan blades, assemble the brackets as  
shown in figure No. 4. Loosen the battery retaining hardware enough  
that you can insert the longer portion of bracket "C" between the bottom  
of the battery and the battery mounting tray. Align the charger to freely  
stand without restrictions, then tighten all hardware.  
ELECTRICAL CONNECTION  
The output leads of the charger are terminated with 3/8 inch ring  
lugs. Remove the bolts from the battery post connector, insert the bolt  
through the ring lug then place the bolt back in the battery connector  
and tighten. Connect the red lead to the positive (+) battery post and  
the black lead to the negative (-) post.  
If you have difficulty connecting the output leads, consult your  
local auto supply store, they may assist you in finding a connecting  
device for, your application.

OPERATING INSTRUCTIONS  
3. Check polarity of battery posts.  
Model SE 112S ystems only. The  
POSITIVE (+) battery post usually  
charger contains afeguards against  
has a larger diameter than the  
overcharging the b
NEGATIVE (-) post.  
4. Determine which post of battery  
is grounded (connected to the  
After reading and
ery in vehicle" or  
chassis). If negative post is

The on/off cycle of the red light will continue, the red light will stay on for longer  
periods of time as the battery becomes more fully charged. Your charger has  
been designed NOT to spark if the ring lugs on the leads accidentally touch one  
another, or if the leads are connected in reverse.  
The battery must measure at least 2 volts to start the charging of the battery. The  
green light will be on even if the charging is not taking place. You can verify  
charging by measuring the battery voltage and noting an increase in volts.  
This charger is ideally suited for maintaining the battery charge level for the  
following applications.  
1. Storage of a battery during non-seasonal use.  
2. For vehicles seldom used or placed in storage.  
3. For improved battery performance during cold weather.  
Smaller batteries such as those used on motorcycles and garden tractors can be  
charged overnight.  
For large automotive or marine battery which are deeply discharged, it is  
recommended to recharge first with a larger charger (such as a 10 amp) then  
use the SE 112S to maintain the charge level of the battery.  
If the battery is used in automobile or other application which has its own means  
of charging a battery, the above time maybe greatly reduced by partially  
charging the battery before applying the charger.  
CHARGING BATTERY IN VEHICLE  
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 parts.  
2. Stay clear of fan blades, belts, pulleys and other parts that can  
cause injury.
