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,

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 markingson these productsand on the engine.
If unableto determine the battery manufacturerer's requirements
for charging,always charge the battery withthe cell caps in place.
Inaddition,make certain that anyone else that uses this
equipment, or is a bystander inthe vicinityof a chargingbattery,
understandand 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.

CHARGING TIME 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.
