CHARGER LOCATION PRECAUTION
Never place charger directly above battery being charged;
gases from battery could damage charger.
Never allow battery acid to drip on charger when reading
specific gravity or filling battery.
Do not operate charger in a closed-in area or restrict
ventilation in any way.
Do not set battery on top of charger.
NOTE: The temporary adapter should be used only until a properly grounded outlet can be installed by a qualified electrician.
DANGER: NEVER alter the 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. DANGER: Before using an 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.
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.
Keep the battery terminals clean and tight. Use terminal
protectors to prevent corrosion.
4. If battery has removable filler vents, check periodically to
make sure battery electrolyte (liquid) covers the plates. If
liquid is down, add water to bring level up. This also helps
purge excessive gas from the cells.
NOTE: DO NOT OVERFILL (OVERFILLING COULD RESULT
IN DAMAGE).

Model SE 112S is intended for use with 12 volt battery systems only. The
charger contains an electronic control circuit which safeguards against
overcharging the battery.
After reading and following the directions "Charging battery in vehicle" or
"Charging battery out of vehicle, " you may observe the following conditions:
Light color on/off Condition
Green off Check wall receptacle for 120
volts or check lead connec
tions, may be reversed.
Green on AC Power is present.
Red on Battery charger voltage is
approximately 14 volts and
charging has stopped.
Red off Battery voltage has dropped
one volt and the charging has
resumed.
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.
