PERSONAL PRECAUTIONS:

a. Someone should be within range of your voice or close enough to come to your aid when you work

near a lead-acid battery.

b. Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.

c. Wear complete eye protection and clothing protection. Avoid touching eyes while working near

battery.

d. If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters an eye,

immediately flood eye with running cold water for at least 10 minutes and get medical attention

immediately.

e. NEVER smoke or allow a spark or flame in vicinity of battery or engine.

f. Be extra cautious to reduce risk of dropping a metal tool onto battery. It might spark or short-circuit

battery or other electrical part that may cause an explosion.

g. Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a

lead-acid battery. A lead-acid battery can produce a short-circuited current high enough to weld a

ring or like to metal, causing a severe burn.

h. It is not intended to supply power to a low-voltage electrical system or to charge dry-cell batteries.

Charging dry-cell batteries may cause them to burst and cause injury to persons and/or damage to

property.

i. NEVER charge a frozen battery.

PREPARING TO CHARGE

a. If it is necessary to remove battery from vehicle to charge it, always remove grounded terminal from

battery first. Make sure all accessories in the vehicle are off in order to prevent an arc.

b. Be sure area around battery is well ventilated while battery is being charged. Explosive gas can be

forcefully blown away by using a piece of cardboard or other nonmetallic material as a fan.

c. Clean battery terminals. Be careful to keep corrosion from coming in contact with eyes.

d. If battery is not sealed, add distilled water in each cell until battery acid reaches level specified by

battery manufacturer. This helps purge excessive gas from cells. Do not overfill. For a sealed battery

or a battery without cell caps, carefully follow manufacturers’ recharging instructions.

e. Study all battery manufacturers' specific precautions such as removing or not removing cell caps

while charging and recommended rates of charge.

f. Determine voltage of battery by referring to vehicle owner’s manual and make sure it matches

output rating of the battery charger.

LOCATE CHARGER

a. Locate the charger as far away from battery as the DC cables permit.

b. Never place the charger directly above or below the battery being charged. Gases or fluids from the

battery will corrode and damage the charger.

c. Never allow battery acid to drip on the charger when reading gravity or filling battery.

d. Do not operate charger in a closed-in area or restrict ventilation in any way.

e. Do not set a battery on top of charger.

CONNECTION PRECAUTIONS

Connect and disconnect DC output clips only after setting the charger switches to off position and removing

AC cord from the electric outlet. Never allow clips to touch each other.

1. Follow these steps when battery is installed in a vehicle. A spark near battery may cause a battery

explosion. To reduce risk of a spark near battery:

a. Position AC and DC cords to reduce risk of damage by hood, door or any moving engine parts.

b. Stay clear of fan blades, belts, pulleys, and other parts that can cause injury to persons.

c. Check polarity of battery posts. A positive (pos, +) battery post may have a larger diameter

than a negative (neg, -) post.

d. Determine which post of battery is grounded (connected) to the chassis. If negative post is

grounded to the chassis (as in most vehicles), see item (e). If positive post is grounded to the

chassis, see item (f).

e. For a negative-grounded vehicle, connect the positive (red) clip from the battery charger to

the positive (pos, +) post of battery first. Connect the negative (black) clip from the battery

charger to the vehicle chassis of engine block remote from the battery and fuel line. Do not

connect the clip to carburetor, fuel lines, or sheet-metal body parts. Connect to a heavy

gauge metal part of the frame or engine block.

f. For a positive-grounded vehicle, connect the negative (black) clip from the battery charger to

negative (neg, -) post of battery first. Connect the positive (red) clip from the battery charger

to the vehicle chassis or engine block remote from the battery and fuel line. Do not connect

clip to carburetor, fuel lines, or sheet-metal body parts. Connect to a heavy gauge metal part

of the frame or engine block.

g. If using permanently mounted eyelet lead SAE connector, simply connect to charger output

lead.

h. Connect charger AC supply cord to an electric outlet.

i. When disconnecting the charger, disconnect AC cord, remove clip from vehicle chassis, and

then remove clip from battery terminal.

j. See operating instructions for length of charge information.

2. Follow these steps when battery is outside the vehicle. A spark near the battery may cause a battery

explosion. To reduce risk of a spark near battery:

a. Check polarity of battery posts. A positive (pos, +) battery post may have a larger diameter

than a negative (neg, -) post.

b. Attach at least a 1.8m long 0.75mm’ insulated battery output cable of charger to the negative

(neg, -) battery post.

c. Connect the positive (red) clip from the battery charger to the positive (pos, +) post of

battery.

d. Position yourself and the free end of cable as far away from battery as possible, then connect

negative (black) clip from the battery charger to free end of cable.

e. Do not face battery when making final connection.

f. Connect charger AC supply cord to an electric outlet.

g. When disconnecting the charger, always do so in reverse sequence of connecting procedure

and break first connection while standing as far away from battery as practical.

h. A marine (boat) battery must be removed and charged on shore. To charge it on boat

requires equipment specially designed for marine use.

OPERATING INSTRUCTIONS:

AUTOMATIC MONITORING - Your new battery charger is completely automatic and can be left on whenever

input power is made available to the charger. The charger output depends on the condition of the battery it

is charging. When the battery is fully charged, the indicating light will turn green and the charger will switch

itself to a storage charge mode and will automatically monitor and maintain the battery at full charge.

CABLE CONNECTIONS: Your new battery charger is equipped with two output leads, a red positive (+) lead,

and a black negative (-) clip lead and a ring terminal cable. Always connect or disconnect the output leads

before plugging into AC power.

For all battery types: Connect the red positive (+) lead to the positive terminal of the battery. Connect the

black negative (-) lead to the negative terminal of the battery.

NOTE: If the charger is left connected to a lead acid battery for long periods of time, check water levels

periodically as directed by the battery manufacturer to ensure electrolyte is maintained at proper level.

ATTENTION: THE BATTERY CHARGER HAS A SPARK FREE, WRONG POLARITY & SHORT CIRCUIT PROTECTION

CIRCUITRY BUILT IN - BUT AS A GOOD PRACTICE, NEVER ALLOW THE TWO CLIPS TOUCH EACH OTHER.

The Battery Charger will not produce voltage (turn on) until it recognizes at least four volts from the battery.

The battery charger clips must be clipped to a battery in the correct polarity to initiate output voltage and

begin charging

If the charger is hooked up in reverse polarity, the “Reverse Polarity" light will flash indicating that the

connection has been made in reverse of the polarity of the battery and a charge has not been initiated. The

clips must be re-connected in the proper polarity to start the charger, Red to Positive (+ to +) and Black to

Negative (- to -).

NOTE: DO NOT TURN YOUR BATTERY CHARGER ON AND OFF REPEATEDLY (Plug and Unplug) WITHIN A

SHORT PERIOD. IF THIS HAPPENS, UNPLUG BATTERY CHARGER FROM AC POWER, WAIT FOR ONE MINUTE

AND THEN CONNECT THE CHARGER AGAIN TO RESTART CHARGING CYCLE.

FULLY DISCHARGED BATTERIES:

If your battery is totally discharged (below 4 volts), the BATTERY CHARGER circuitry will not start due to its

internal safety circuit. The internal safety circuit of the battery charger must sense more than 4 volts in the

battery before it will allow the charging circuit to turn on. Otherwise, the charger is inoperable. In this case

(battery voltage between 0.5V 4.0V), the Indicator Light will flash, which means charging has not been

initiated. If the battery voltage is less than 0.5V, the charger will be returning to STANDBY mode.

Note: Unless the battery was rapidly discharged (lights left on overnight) most 12-volt lead acid batteries

that are at a state of charge that is less than 9 volts are likely to be worn out or defective.

72-HOUR SAFETY FEATURE:

A 72-hour Safety Timer will commence anytime the charger is on. This feature is designed to protect

marginal batteries from over charging. If the battery voltage reaches the proper level within 72 hours, the

charger will automatically switch to maintenance mode. If your battery is marginal or defective, the Battery

Charger will stop all the charging processes in order to protect the marginal battery from over charging.

Please check battery condition as it could also indicate that a very large (high capacity) but good battery is

simply not yet fully charged. When this happens, the bad battery indicator will be flashing. If this is the case,

please contact your local dealer and have the battery tested.
