3. Attach a battery or booster cable, AT LEAST 24 inches

long that is the same (or larger) wire gauge as the charg-

er cable, to the NEGATIVE terminal of the battery.

WARNING

BATTERY EXPLOSION CAN INJURE, AND CAUSE

PROPERTY DAMAGE!

To reduce the risk of battery explosion, NEVER CON-

NECT BOTH BATTERY CHARGER CLAMPS DIRECTLY

TO THE TWO POSTS OF A BATTERY.

4. Connect the POSITIVE (red) charger clamp to the POSI-

TIVE battery terminal.

5. Position yourself and the free end of the cable (attached

to the NEGATIVE battery terminal) as far away from the

battery as the cable will allow. Then, WHILE FACING

AWAY FROM THE BATTERY, connect the NEGATIVE

charger clamp to the free end of the cable.

CHARGING INSTRUCTIONS

1. Determine the length of time necessary to charge the

battery in CHARGING TIME INSTRUCTIONS, but do not

start the timer.

2. Set all switches and the timer to OFF and connect the

charger power cord into an appropriate ac outlet.

3. Set charging voltage, charging rate, and any other func-

tions according to CONTROL SETTING INSTRUC-

TIONS.

4. On models so equipped, set the TIMER for the desired

length of charge time.

WARNING

BATTERY EXPLOSION CAN INJURE, AND CAUSE

PROPERTY DAMAGE!

To reduce risk of battery explosion, do not overcharge a

lead-acid battery. Follow disconnection procedure

EXACTLY.

5. When charging is complete, turn all charger controls to

OFF. Then unplug the charger's ac power cord from the

ac power source.

6. Disconnect the charger clamp NOT attached directly to

the battery first and DO NOT allow the clamp to touch

anything. Then, disconnect the charger clamp attached

to the battery terminal.

READING AN AMMETER

The ammeter indicates the charging current being drawn

from the charger by the battery. As the battery becomes

more fully charged, the charge rate lessens and the amme-

ter needle moves toward the lower amp numbers on the

meter. During engine starting, the ammeter will usually peg

to the high-amperage end of the meter.

There is no clear-cut way to read an ammeter and deter-

mine exactly when charging is complete (if the charger is so

equipped, a green light on the charger indicates battery is

fully charged). At full charge, the ammeter will still register

some current draw (approximately 50% of the charger's out-

put rating). In many cases, overcharging can occur if the

charger is not disconnected when the battery reaches full

charge - or sooner. Therefore, it is very important that you

follow the CHARGING TIME INSTRUCTIONS provided in

this manual.

Several battery conditions can also cause the ammeter to

appear to indicate a battery near full charge, when in fact,

charging has only begun.

Cold Battery

Sulfated Battery

Deeply-Discharged, Lead-Calcium Battery (many

newer automotive batteries)

WARNING

BATTERY EXPLOSION CAN INJURE, AND CAUSE

PROPERTY DAMAGE!

To reduce risk of battery explosion, check to make sure a

cold battery is not frozen. Battery explosion can result

from attempting to charge a frozen battery.

COLD BATTERIES (temperatures lower than 32° F or

0° 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.

SULFATED or DEEPLY-DISCHARGED LEAD-CALCI-

UM BATTERIES - require a special activation proce-

dure. See DEEPLY DISCHARGED LEAD-CALCIUM

BATTERIES in CHARGING TIME INSTRUCTIONS.

SHORTED BATTERIES - When the battery being

charged has a short circuit, the ammeter will peg at the

high-amp end of the scale. If after 5 to 10 minutes of

charging, the needle has not started to move toward

lower amperages, unplug the charger and discontinue

charging.

If available, use a voltmeter and read the battery voltage. If

the voltage is LESS THAN 12.0 volts for a 12 volt battery or

LESS THAN 6.0 volts for a 6 volt battery, plug the charger

back in and resume charging. If after another 15 to 20 min-

utes, the ammeter has failed to move toward lower amper-

ages, repeat the voltmeter test. If the voltage has not

increased, the battery needs to be serviced or replaced.

CAUTION

DO NOT USE AMMETER to determine when full charge

is reached. Failure to comply with this caution could

cause the battery to be damaged from overcharging. The

battery could overheat and even explode.

CHARGING TIME INSTRUCTIONS

Manual battery chargers need to be disconnected from a

battery when the battery has reached 100% of charge OR

SOONER. If this is not done, the battery will overcharge,

resulting in possible battery damage.
