RISK OF EXPLOSIVE GASES.

WORKING IN THE VICINITY OF A LEAD-ACID BATTERY 1.10
IS DANGEROUS. BATTERIES GENERATE EXPLOSIVE
GASES DURING NORMAL BATTERY OPERATION. FOR
THIS REASON, IT IS OF UTMOST IMPORTANCE THAT YOU
FOLLOW THE INSTRUCTIONS EACH TIME YOU USE THE
CHARGER.

To reduce the risk of a battery explosion, follow these instructions 1.11
and those published by the battery manufacturer and the
manufacturer of any equipment you intend to use in the vicinity
of the battery. Review the cautionary markings on these products
and on the engine.

PERSONAL PRECAUTIONS2.

RISK OF EXPLOSIVE GASES.

NEVER smoke or allow a spark or ame in the vicinity of a battery 2.1

or engine.
Remove personal metal items such as rings, bracelets, necklaces 2.2

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.

Be extra cautious to reduce the risk of dropping a metal tool onto 2.3
the battery. It might spark or short-circuit the battery or other
electrical part that may cause an explosion.

• 3 •

Use this charger for charging LEAD-ACID batteries only. It is not 2.4
intended to supply power to a low voltage electrical system other
than in a starter-motor application. Do not use this 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.

NEVER charge a frozen battery.2.5
NEVER overcharge a battery.2.6
Consider having someone close enough by to come to your aid 2.7

when you work near a lead-acid battery.
Have plenty of fresh water and soap nearby in case battery acid 2.8

contacts your skin, clothing or eyes.
Wear complete eye and body protection, including safety goggles 2.9

and protective clothing. Avoid touching your eyes while working
near the battery.

If battery acid contacts your skin or clothing, immediately wash 2.10
the area with soap and water. If acid enters your eye, immediately

ood the eye with cold running water for at least 10 minutes and

get medical attention right away.
If battery acid is accidentally swallowed, drink milk, the whites of 2.11

eggs or water. DO NOT induce vomiting. Seek medical attention
immediately.

PREPARING TO CHARGE3.

RISK OF CONTACT WITH BATTERY
ACID. BATTERY ACID IS A HIGHLY
CORROSIVE SULFURIC ACID.

If it is necessary to remove the battery from the vehicle to charge 3.1

it, always remove the grounded terminal rst. Make sure all of the

accessories in the vehicle are off to prevent arcing.
Be sure the area around the battery is well ventilated while the 3.2

battery is being charged.

• 4 •

Clean the battery terminals before charging the battery. During 3.3
cleaning, keep airborne corrosion from coming into contact
with your eyes, nose and mouth. Use baking soda and water to
neutralize the battery acid and help eliminate airborne corrosion.
Do not touch your eyes, nose or mouth.

Add distilled water to each cell until the battery acid reaches the 3.4

level specied by the battery manufacturer. Do not overll. For

a battery without removable cell caps, such as valve regulated
lead acid batteries (VRLA), carefully follow the manufacturer’s
recharging instructions.

Read, understand and follow all instructions for the charger, 3.5
battery, vehicle and any equipment used near the battery

and charger. Study all of the battery manufacturer’s specic

precautions while charging and recommended rates of charge.
Determine the voltage of the battery by referring to the vehicle 3.6

owner’s manual and make sure that the battery voltage matches
the charger output voltage (12V).

Make sure that the charger cable ring terminal connections are 3.7
attached to the battery and ground securely.

CHARGER LOCATION4.

RISK OF EXPLOSION
AND CONTACT WITH
BATTERY ACID.

When mounting the charger to the fender well, locate the charger 4.1
as far away from the battery as the DC cables permit.

Never place the charger directly above the battery being charged; 4.2
gases from the battery will corrode and damage the charger.

With the exception of the charger mounting bracket, do not set the 4.3
battery on top of the charger.

Never allow battery acid to drip onto the charger when reading the 4.4

electrolyte specic gravity or lling the battery.

OPERATING INSTRUCTIONS12.

This battery charger must be properly assembled in

accordance with the assembly instructions before it is used.
The charger does not have an ON/OFF switch. The On and Off

commands are controlled by plugging the charger into a 120V AC
electrical wall outlet only after the battery connections have been
made.

Charging

Ensure that all of the charger components are in place and in 1.
good working condition.

Connect the battery following the precautions listed in sections 6 2.
and 7.

Connect the AC power following the precautions listed in 3.
section 8.

The POWER ON (green) LED will light when the AC cord is 4.
properly connected. When the battery is charged the CHARGED
(red) LED will light.

To disconnect, reverse the procedure. 5.

NOTE: This charger is equipped with an auto-start feature. Current
will not be supplied to the ring terminals until a battery is properly
connected. Meaning, the clips will not spark if touched together.

AutomaticChargingMode
When an Automatic Charge is performed, the charger switches to the
Maintain Mode (see below) automatically after the battery is charged.
For a battery with a starting voltage under 1 volt, use a manual

charger to pre-charge the battery for ve minutes to get additional

voltage into the battery.

• 11 •

CompletionofCharge
Charge completion is indicated by the CHARGED LED. When lit, the
charger has switched to the Maintain Mode of operation.

MaintainMode(Float-ModeMonitoring)
When the CHARGED LED is lit, the charger has started Maintain
Mode. In this mode, the charger keeps the battery fully charged by
delivering a small current when necessary. If the battery voltage drops
below a preset level, the charger will go back into Charge Mode until
the battery voltage returns to the full charge level, at which point the
charger will return to Maintain Mode.

NOTE: The charger automatically switches between Charge Mode
and Maintain Mode as necessary. The CHARGED LED will cycle
on when the battery is at full charge and off when the voltage drops
below a preset level and the charger goes into Charge Mode. This
cycle will continue, and the CHARGED LED will stay on for longer
periods of time as the battery becomes more fully charged.

Maintaining a Battery

The Schumacher SE-1-12S and SF-1-12S are battery maintainers
that maintain 12 volt batteries, keeping them at full charge. It can
charge small batteries and maintain both small and large batteries.
If you are maintaining a fully charged large battery, you will be
properly utilizing the battery charger. However, if you were to use
this battery charger to charge a large battery, such as a marine deep
cycle battery, that was not fully charged, you may lose some of the
battery’s capacity. This would cause the large battery to be unable to
hold a charge and become useless. Therefore, we do not recommend
charging a large battery with this unit.

NOTE: The maintain mode technology utilized in Schumacher
maintainers allows you to safely charge and maintain a healthy
battery for extended periods of time. However, problems with the
battery, electrical problems in the vehicle, improper connections or
other unanticipated conditions could cause excessive current draws.
As such, occasionally monitoring your battery and the charging
process is recommended.

• 12 •

MAINTENANCE INSTRUCTIONS13.

After use and before performing maintenance, unplug and 13.1
disconnect the battery charger (see sections 6, 7 and 8).

Use a dry cloth to wipe all battery corrosion and other dirt or oil 13.2
from the battery terminals, cords, and the charger case.

Ensure that all of the charger components are in place and in 13.3
good working condition.

Servicing does not require opening the unit, as there are no user-13.4
serviceable parts.

All other servicing should be performed by qualied service 13.5

personnel.
