INTRODUCTION

HOW BATTERIES CHARGE

A charger DOES NOT FORCE current into a battery - it makes a

limited amount of current available and the battery draws as much

of it as it needs, up to or slightly greater than the OUTPUT AMP

rating of the charger.

The closer a battery is to zero-charge ("dead"), the more charging

current it will want to draw. When charging begins on a "dead"

battery, a charger!s ammeter (if so equipped) will register toward

the high amps end of the scale and fall toward the zero end as the

battery becomes more fully charged. KEEP IN MIND: the

ammeter registers the amount of amperage being drawn from the

charger by the battery, not what the charger is capable of

delivering.

One would expect a battery to draw zero amps when it reaches

100% of charge. But at 100% of charge, the battery will continue

to draw a low level of current and convert it into heat within the

battery. If left connected to a MANUAL charger after reaching

100% of charge, the battery acid will begin to boil, resulting in

overcharging and possible battery damage.

But the Sears #71614 battery charger is FULLY-AUTOMATIC.

When full charge is reached, it will completely shut off the

charging current to the battery. If the battery were to discharge for

some reason, the charger will automatically resume charging the

battery until full charge is reached again.

SPARK PREVENTION

MAKE SURE NO SPARKS OR FLAMES OCCUR NEAR THE

BATTERY, especially during charging. It takes very little to ignite

the explosive gasses produced by a lead-acid battery. Read,

understand, and follow the SAFETY INSTRUCTIONS section of

this manual before attempting to work with or near a lead-acid

battery,

IMPORTANT SAFETY INSTRUCTIONS

control(s) to their "OFF" position(s) alone will not remove all

electricity from the charger.

EXPLOSION HAZARDS

WARNING! - RISK OF EXPLOSIVE GASSES!

Working Jnthe vicinity of a lead-acid battery is dangerous.

Batteries generate explosive gasses during normal operations

and, at an even higher level, during charging. If anything is

allowed to ignite these gasses, the battery may explode, sending

pieces of the battery and extremely caustic battery acid out in all

directions and with extreme force. Since just the slightest spark is

sufficient to ignite these gasses, it is of UTMOST IMPORTANCE

that you read this manual and follow the instructions exactly,

before using your battery charger each time.

BATTERY EXPLOSION CAN KILL, INJURE, AND

CAUSE PROPERTY DAMAGE! To reduce the risk of battery

explosion, read, understand, and follow these instructions,those

published by the battery manufacturer, and those of the

manufacturerof any equipment you intendto use near the battery.

Review cautionary markings on these productsand on the engine.

If unable to determine the battery manufacturerer's requirements

for charging,always charge the battery withthe cell caps in place.

In addition,make certain that anyone else that uses this

equipment, or is a bystander in the vicinityof a charging battery,

understand and follow these safety instructionsas well.

NEVER smoke or allow a spark or flame in the vicinity of the

battery or engine.

NEVER operate the battery charger in a closed-in area or restrict

ventilation in any way.

NEVER charge a frozen battery as battery explosion can result.

NEVER connect BOTH battery charger clamps DIRECTLY to the

twoposts of the same battery. SEE OPERATING

INSTRUCTIONS FOR PROPER CONNECTION PROCEDURES.

NEVER charge batteries other than a LEAD-ACID type.

Especially, DO NOT use for charging dry-cell batteries that are

IMPORTANT SAFETY INSTRUCTIONS

commonly used with toys and home appliances. These batteries

may burst and cause injury to persons or damage property.

NEVER allow the DC output clamps to touch each other.

ALWAYS be extra cautious to reduce the risk of dropping a metal

object, such as a too!, onto or near the battery. Doing so could

produce a spark or short circuit the battery or other electrical part

that could cause an explosion.

ALWAYS make sure the area around a battery is well ventilated

while it is being charged. Gas can be forcefully blown away by

using a piece of cardboard or other non-metalic material as a fan.

ALWAYS make sure that theAC _wercord is unplugged from the

AC outlet or extension cord BEFORE connecting or disconnecting

the battery charger clamps to the battery to prevent arcing or burning.

ALWAYS locate the batter){, charger as far away from the battery

as the DC output cables w_l! permit.

ALWAYS twist or rock charger clamps back and forth several times

on the battery post and the 6ther point of connection at the time of

initial connection. This helps keep the clamps from slipping off their

points of connection which helps reduce the risk of sparking.

NOTE: DO NOT rock the clamp connected to the battery post

AFTER the second connection (at apoint away from the battery)

is made or sparking may occur at the battery post.

FIRE HAZARDS

FIRE CAN KILL, INJURE, AND CAUSE PROPERTY

DAMAGE! _

NEVER use an attachment not recommended or sold by the battery

charger manufacturer for use with your specific model charger.

NEVER dissassemble the battery charger; take it to qualified

service personnel when service or repair is needed.

IMPORTANT SAFETY INSTRUCTIONS

ALWAYS make sure that the AC powercord is unplugged from the

AC outlet or extension cord, BEFORE connecting or disconnecting

the battery charger clamps, to prevent arcing or burning.

BA'I-rERY ACID HAZARDS

BATTERY ACID CAN CAUSE SERIOUS INJURY AND

PROPERTY DAMAGE!

ALWAYS have someone within range of your voice and close

enough to quickly come to your aid when working near a lead-acid

battery.

ALWAYS have plenty of fresh water and soap nearby in case

battery acid contacts eyes, skin, Or clothing.

ALWAYS wear complete eye and clothing protection and avoid

touching eyes while working with a battery,

ALWAYS act QUICKLY if contact with battery acid is made. If

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.

SHORT CIRCUIT HAZARDS

ELECTRICAL SHORT CIRCUITS CAN INJURE!

ALWAYS remove personal metal items such as rings, bracelets,

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 orthe like to metal causing a severe burn.

IMPORTANT SAFETY INSTRUCTIONS

MOVING PARTS HAZARDS

MOVING ENGINE PARTS CAN INJURE!

NEVER connect or disconnect battery charger clamps to a vehicle

when the engine is running.

ALWAYS stay clear of fan blades, fan belts, pul!eys and other

moving engine parts when working near an engine. Moving

engine parts can cause severe personal injury including

dismemberment.

ALWAYS make sure that battery chargercables and clamps are

positionedso they will not come Jncontact with any moving engine parts.

IMPORTANT SAFETY INSTRUCTIONS

CHARGING TIME INSTRUCTIONS

1"2VOLT BATTERIES

The AUTOMATIC CHARGING CIRCUIT will prevent over

charging a 12 volt battery, so accurate calculation of length of

charging time is unnecessary. When full charge is reached, the

output of the charger will be turned off and the green CHARGE

COMPLETE INDICATOR will turn on. If the charger is left

connected to the battery, it will monitor the battery's state of

charge and turn the charger's output back on if the battery

discharges.

However, for an idea as to how long the charging process may

take, see the following CHARGING TIME CHART or CHARGING

TIME EQUATIONS.

6 VOLT BATTERIES

The 6 volt charging setting is a MANUAL operation. When the

battery reaches full charge, the charger must be promptly

unplugged from the AC outlet and disconnected from the battery.

If this is not done, overcharging can occur that could result in

damage to the battery.

Use the CHARGING TIME CHART or CHARGING TIME

EQUATIONS to determine how long to charge your 6 volt battery.

ALWAYS set a time-warning device, such as an alarm clock, to

remind you to discontinue charging.

DETERMINING TIME TO CHARGE

1. Determine the battery's present state of charge with a

hydrometer or electronic percent-of-charge tester.

2. Convert hydrometer readings to percent of charge.

NOTE: These times are for reference only. Actual times may vary

due to battery design and physical condition of the battery.

For a more accurate determination of length of charging time, use

Equation 1.

CHARGING TIME INSTRUCTIONS

First, determine percent-of-charge-NEEDED to bring the battery to

full charge. This is 100% minus the present percent of charge of

the battery (determined above). Then, to use it in the equation,

express the percent-of-charge-needed as a decimal.

EXAMPLE:

Battery,s Present State of Charge = 25%

Percent-Of-Charge-Needed: 100% - 25% = 75%

To express as a decimal, insert a decimal point two digits to the

left of the percent sign (%), then drop the percent sign: 75% = .75

Next, use this decimal in the equation below, along with the =

battery's amp-hour rating, and the charge rate (amp) setting

selected on the charger, to determine time to charge,

CHARGER CONTROLS AND FEATURES

AMP SELECTOR is to be set to the same voltage as the battery

to be charged: 6 or 12 volts. For 12 volt batteries, there are 2

charge rate settings to choose from: 10 amps or 2 amps. These

two settings are controlled by the AUTOMATIC CHARGING

CIRCUIT. The 6 volt setting is a 10 amp manual charge rate.

NOTE: The 2 amp setting should be selected to charge only

SMALL 12 volt batteries. If used to charge larger automotive or

deep-cycle batteries, full charge may never be fully reached.

When the switch is set to its right-most setting, 60 amps of engine

starting power is available. When this setting is used, the

FUNCTION SELECTOR must be set to the right or START

position. •

IMPORTANT! The 6 volt setting is NOT automatic. The charger

must be manually-disconnected when a 6 volt battery reaches full

charge to prevent overcharging and battery damage.

SMALL 12 VOLT BATTERIES, such as those used in

motorcycles, lawn tractors, and snowmobiles, have a maximum

charge rate limit. Unless otherwise stated on a particular battery,

always charge small 12 volt batteries on the 2 amp setting to

prevent battery damage.

FUNCTION SELECTOR has 2 positions: CHARGE and

START/ACTIVATE. It must be set in the CHARGE position when

ever 6 or 12 volt charging is desired. The only time it is moved to

START/ACTIVATE is for engine starting or pre-charge activation.

CHARGER CONTROLS AND FEATURES

IMPORTANT! If charging is attempted when the FUNCTION

SELECTOR is inthe START position,the automaticcircuitry will

be bypassed, causingall settings to be manual.

BATTERY TYPE SELECTOR must be set for the type of battery

beingcharged. Set to the left DEEP-CYCLE positionfor charging

deep-cycle batteries or any other battery with a built-inhydrometer

"eye", such as the Delco Freedom battery. Set all other battery

types to the right ALL OTHER position.

CAUTION - SET SWITCH CORRECTLY!

Charging a standard battery on the DEEP-CYCLE setting may

result in excessive gassing and possible overcharging.

Charging a deep-cycle battery on the ALL OTHERS setting will

result inan undercharged battery.

Charging a battery (such as a Delco Freedom) with a built-in

hydrometer "eye" on the ALL OTHERS setting will result in a fully

charged battery, but the "eye" may fail to change to indicate a

satisfactory charge level.

AUTOMATIC CHARGING CIRCUIT controls the two 12 volt

settings. It monitorsthe battery's state of charge and

automaticallyreduces the current to the battery as it nears full

charge. In some cases, it will taper to such a low rate that the

ammeter wilt appear to be on or near zero for some time. When

full charge is reached, the outputto the battery is completely shut

off and the green CHARGE COMPLETE indicatorcomes on. At

thispoint, the charger continuesto monitorthe battery's state of

charge. If the batterydischarges for any reason, the charger will

turnthe output back on until the battery reaches full charge once

again.

NOTE: The 2 amp setting should be selected to charge only

SMALL 12 volt batteries. If used to charge larger automotive or

deep-cycle batteries, full charge may never be fully reached.

The automatic charging circuit is temperature compensating.

will assure that a full charge is reached regardless of the

temperature at which it is being used.

This

REVERSE HOOK-UP PROTECTION CIRCUIT will not allow the

charger to begin charging and will light the red REVERSE

HOOK-UP indicator if the charger is connected to the battery in

reverse.

CHARGER CONTROL5 AND FEATURE,_5

CHARGE COMPLETE INDICATOR lightturns on when the

battery reaches full charge. This lightonly operates when the

charger is in one of the two 12 volt charging modes and the

FUNCTION SELECTOR is set to CHARGE. It will indicate

complete charge even if the charger is unplugged.

REVERSE HOOK-UP INDICATOR lightturns on when the

charger clamps are connected to a battery in reverse. This light

will turn on whenever a reverse hook-upoccurs,regardless of how

the three switchesare set.

AMMETER indicates the charging current being drawn from the

charger by the battery. As the batterybecomes more fully

charged, the charge rate lessens and the ammeter needle moves

toward the lower amp numbers on the meter.

CAUTION - DO NOT USE AMMETER TO DETERMINE WHEN

FULL CHARGE IS REACHED!

When charging small 12 volt batteries on the 2 amp setting, or

when any batter,.., nears full charge, the ammeter needle will be

•very close to zero. When_charging 12 volt batteries, the automatic

circuit is in control of the charging process. When full charge is

reached, the output shuts off and the green CHARGE

COMPLETE indicator lights up. But when_charging 6volt

batteries, overcharging can occur if the chargeris not

disconnected once full charge is reached. Therefore, it is

important to follow the CHARGING TIME INSTRUCTIONS, earlier

in this manual, when charging 6 volt batteries. When the charger

will be used for engine starting, the ammeter needle will move into

the "Start" range on the ammeter.

Several battery conditions can also cause the ammeter to appear

to indicate a battery near full charge, when in fact charging has

only begun.

m Cold Battery

Sulfated Battery

Deeply-Discharged Lead-Calcium Battery (many newer

automotive batteries)

COLD BATTERIES (temperatures lower than 32 degrees F or 0

degrees C) will begin charging at a low rate of charge. But as the

battery warms up through charging, the charge rate will increase.

Then, as the battery charges up, the charge rate will decrease

normally.

CHARGER CONTROLS AND FEATURES

SULFATED and DEEPLY-DISCHArGED LEAD-CALCIUM

BATTERIES require a special activation procedure. Refer to the

following PRE-CHARGE ACTIVATION instructions.

SHORTED BATTERIES -When the battery being charged has a

short circuit,the ammeter will "pin" tothe far right in the "Start"

range.'If after 5 to 10 minutes of charging,the needle has not

startedto movetoward lower amperages, unplugthe charger and

discontinuecharging. Ifavailable, use a voltmeter and read the

voltage of the battery, ifthe voltage is under 12.0 volts for a12

volt battery,or 6.0 volts for a 6 voltbattery, plug the charger back

in and resume charging. Ifafter another 15 to 20 minutes, the

ammeter has failed to move toward loweramperages, repeat the

voltmeter test. Ifthe voltage has not increased, the battery needs

to beserviced or replaced.

PRE-CHARGE BATTERY ACTIVATION (12 Volt Only)

PRE-CHARGE BATi"ERY ACTIVATION

The need for pre-charge activation is indicated when the ammeter

reads zero and neither the REVERSE HOOK-UP or CHARGE

COMPLETE indicators are lit, or if a battery is known to be dead

and the CHARGE COMPLETE light comes on after charging just

a few minutes. It should be needed only when charging sulfated

or deeply-discharged lead-calcium batteries (such as the Delco

Freedom and many newer automotive batteries).

Pre-charge activation is a two-step process:

CHARGER ACTIVATION - These types of batteries can be down

to such a low voltage (less than I volt) that they can "trick" the

automatic circuit into thinking that the charger is not connected to

a battery and will not allow charging to begin. The automatic

circuit must then be temporarily bypassed until the battery voltage

is raised to alevel that the charger can detect.

CAUTION -IF "CHARGE COMPLETE" INDICATOR IS LIT, DO

NOT ATTEMPT PRE-CHARGE ACTIVATION UNTIL VERIFYING

(WITH HYDROMETER OR ELECTRONIC PERCENT OF

CHARGE TESTER) THAT THE BATTERY iS DISCHARGED.

1. With the AMP SELECTOR set to the desired charge setting,

move the FUNCTION SELECTOR to ACTIVATE. The

charger's automatic circuit is now bypassed and the charger is

in a manual charge mode.

2. Allow the charger to charge for 10 minutes, then move the

FUNCTION SELECTOR back to CHARGE to return to

automatic charging.

The green light and ammeter needle will now be pulsing rapidly.

The pulsing will begin to s!ow and the ammeter needle will be

slightly off zero. When the needle reaches about 2 amps, the

green lightwill go off completely.

3. The charger is now in control of the charging process.

NOTE: if the green light goes out AND the ammeter falls back to

zero, repeat steps 1 and 2 above.

BATTERY ACTIVATION - After activating the charger, the

ammeter may continue to display very low amps until the sulfate

barrier, on the plates of the battery, is broken through. This can

take as long as 4 to 8 hours. After breaking through the sulfate

barrier, the ammeter will register higher amps. Charging will now

PRE-CHARGE BATTERY ACTIVATION (12 Volt Only)

progress normally and the ammeter Will decrease as the battery

takes a charge.

If you estimated the length of time to charge the battery, charging

time begins from the time the charger finally breaks through the

sulfate barrier.

It should be noted that battery activation time cannot be

shortened. Each_individual battery and its condition will determine

how long it takes to break through the sulfate barrier.

CAUTION -DO NOT LEAVE CHARGER UNATTENDED

DURING PRE-CHARG E ACTIVATION. OVERCHARGING

COULD OCCUR, RESULTING IN BATTERY DAMAGE OR

EXPLOSION. RETURN TO THE "CHARGE" FUNCTION

WITHIN 10TO 15 MINUTES.

CHARGING BATTERIES WITH BUILT-IN HYDROMETER "EYE"

CHARGING BATTERIES WITH BUILT-IN

HYDROMETER "EYE"

Often, maintenance free lead-calcium batteries are equipped with

a built-in hydrometer "eye" that indicates the battery's state of

charge (such as the Delco Freedom). Many deep-cycle batteries

are also equipped with this "eye". In order to make the "eye"

indicate properly at full charge, it is important to follow these

instructions.

1. Always charge these batteries with the BATTERY'TYPE

SELECTOR set to DEEP-CYCLE, regardless of battery type.

2. After the green CHARGE COMPLETE indicator comes on, it

may take more than 1 hour for the "eye" to indicate full charge.

.Always follow the battery manufacturer's instructions. Some

recommend tilting or lightly shaking the battery once an hour

during charging. This helps mix the acid that has stratified

during charging, with the stronger acid at the bottom of the

battery.

NOTE: Regardless of whether or not the "eye" indicates full

charge, if the green CHARGE COMPLETE indicator comes on,

the battery is at full charge.
