WARNING -- RISK OF EXPLOSIVE GASES
1. WORKING IN THE 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 SCM54E, YOU READ THIS MANUAL
AND FOLLOW THE INSTRUCTIONS EXACTLY.
2. To reduce risk of battery explosion, follow these instructions and
those published by the battery manufacturer and manufacturer of any
equipment you intend to use in the vicinity of the battery. Observe
cautionary markings on these items.
PERSONAL SAFETY 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 protective clothing.
4. Avoid touching eyes while working near battery.
5. If battery acid contacts skin or clothing, wash immediately with soap
- GB.3-V1 -

and water. If acid enters eye, immediately flood eye with running
cold water for at least ten minutes and get medical attention
immediately.
6. NEVER smoke or allow a spark or flame in vicinity of battery or
engine.
7. Be extra cautious to reduce risk of dropping a metal tool onto the
battery. It could spark or short-circuit the battery or other electrical
parts and could cause an explosion.
8. Remove personal metal items such as rings, bracelets, necklaces and
watches when working with a lead acid battery. It can produce a
short circuit current high enough to weld a ring or the like to metal
causing a severe burn.
PREPARING TO CHARGE：
1. 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.
2. Clean battery terminals. Be careful to keep corrosion from coming in
contact with eyes.
3. Inspect the battery for cracked or broken case of cover. If battery is
damaged, do not use charger.
4. If the battery is not sealed maintenance free, add distilled water in
each cell until battery acid reaches level specified by the
manufacturer. This helps purge excessive gas from cells. Do not
overfill. For a battery without cell caps, carefully follow
manufacturer’s recharging instructions.
5. If necessary to remove battery from vehicle to charge, always
remove ground terminal from battery first. Make sure all accessories
in the vehicle are off to ensure you do not cause any arcing.
6. Study all battery manufacturer’s specific precautions such as
removing or not removing cell caps while charging and
recommended rates of charge.
7. Determine voltage of battery by referring to car owner’s manual and
make sure it matches output rating of battery charger.
8. If the battery and terminals have a white or bluish crust on them, the
charging system may be having problem. These problems should be
- GB.4-V1 -

corrected before the battery is replaced after charging.
CHARGER/MAINTAINER 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 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.
SETTING UP & OPERATIONS:
1. Make sure the room has plenty of ventilation.
2. Mount SCM54E away from any vehicle repair or service. Make sure
never to start or run an engine near the batteries being charged.
3. Be sure the total amperage used by SCM54E should not exceed the
amperage capacity of the supply source. If you do not know how to
determine this, have a qualified electrician determine the capacity
for you.
4. Connect and disconnect DC output clips only after removing AC
cord from electric outlet. Never allow clips to touch each other.
5. Make sure the battery terminals are clean. Wire brush them if
necessary. Clamp the black lead to the negative battery terminal.
Clamp the red lead to the positive battery terminal.
6. Connect SCM54E to a grounded power receptacle that is wired in
compliance with local electrical codes.
※Side mounted batteries will require the insertion of a lead post
adapter. Plain bolts are not safe. They will not allow for accurate
reading and should not be used.

8. When SCM54E is being used, it will show LED lights as follows:
Green and red LED light both off: NO AC Power
There is no AC power applied.
Green light flashing only: Standby for charging batteries
Before using, please check following:
a. Are clamps properly connected to batteries?
b. Is the battery voltage below 1 voltage?
c. Is there any battery under charge?
Green light on & red light flashing: Charging batteries
SCM54E is charging the batteries.
Red light on only: Defective battery or deeply discharged
battery
Please make sure again the battery posts and clamps are all clean.
If the red light continues:
a. Check if the batteries are 12V battery or not.
b. If yes, the battery does not hold a charge. It should be
replaced immediately.
c. Or it needs more time to charge deeply discharged battery.
If the red light still lightens after 20 hours charging, please
replace the battery.
Green light & red light both on : 75% Charged
The battery is at least 75% charged and is ready to load test or can
be returned to serve. Continued charging will get the battery to be
fully charged.
※Some battery will pass and accept a charge, but will not be able to
pass a load test. All batteries should be load tested after charging.
Green light on only : Batteries is fully charged and is under
maintaining
It will automatically adjust the voltage/current relationship to
maintain the battery at a full charge. The battery is ready for a load
test or return to serve. If the battery voltage drops below 12.8 volts,
SCM54E shifts automatically into charging mode and recharges to
an OCV of 14.8 volt.

1st Stage: Desulfation:
Focused on deeply discharged or lightly sulfated batteries, which show
low voltage and are hard to activate. The SCM54E Charger will start the
charge pulse to charge the battery until the voltage recovers & reaches
expected rechargeable level. The purpose of this stage is to save an
over-discharged or a lightly sulfated battery for recovery.
2nd Stage: Fast Charge:
When the voltage of the battery is above the set level. The SCM54E
Charger carries a high current to charge the battery quickly until the
battery is returned to 75% of the charge. The purpose of this stage is to
charge battery in the fastest and most efficient manner.
3rd Stage: Equalization & Analysis:
When the voltage reaches a maximum safe (pre-determined) voltage,
The SCM54E will discontinue the Fast Charge automatically & start a
charge pulse with a smaller steam current to charge the battery. The
purpose of this stage is to fully charge the battery in safe manner.
4th Stage: Top-Off Charge:
Under this stage, the SCM54E Charger will shut off automatically when
the battery is 100% charged. The charger will monitor the battery
voltage continually to decide whether a new charge pulse should come.
The purpose of this stage is to fully charge the battery without
overcharging the battery.
5th Stage: Maintain Floating:
If the voltage drops below the pre-set level by battery self-discharge, the
SCM54E Charger starts a charge pulse with a small current to maintain
the battery in full-charge status. The cycle is repeated as long as the
charger is in “Maintain Floating” mode.
