WARNING - RISK OF EXPLOSIVE GASES

WORKING IN VICINITY OF A LEAD-ACID BATTERY IS DANGEROUS. BAT-

TERIES GENERATE EXPLOSIVE GASES DURING NORMAL BATTERY

OPERATION. FOR THIS REASON, IT IS OF UTMOST IMPORTANCE THAT

EACH TIME BEFORE USING YOUR CHARGER, YOU READ THIS MANUAL

AND FOLLOW THE INSTRUCTIONS EXACTLY.

To reduce risk of battery explosion, follow these instructions and those published by

battery manufacturer and manufacturer of any equipment you intend to use in vicinity of

battery. Review cautionary markings on these products and on engine.

• WARNING: Handling the cord on this

product or cords associated with ac-

cessories sold with this product, may

expose you to lead, a chemical known

to the State of California to cause

cancer and birth defects or other

reproductive harm. Wash hands after

handling.

• Read all instructions and cautions

printed on the battery charger, battery,

and vehicle or equipment using bat-

tery.

• Use charger only on lead-acid type

rechargeable batteries, such as those

used in cars, trucks, tractors, air-

planes, vans, RVs, trolling motors, etc.

This charger is not intended to supply

power to a low voltage electrical

system other than in a starter-motor

application.

• Never use charger for charging dry

cell batteries that are commonly used

with home appliances like radios, ste-

reos, remote controls, etc. These bat-

teries may burst and cause personal

injury.

• Do not disassemble charger. Take it

to a qualified service professional if

service or repair is required. Incorrect

assembly may result in fire or electri-

cal shock.

• To reduce risk of electrical shock,

unplug the charger from the outlet

before attempting any maintenance

or cleaning.

• Always charge battery in a well-ven-

tilated area.

• WARNING: Battery chargers get

hot during operation and must have

proper ventilation. Air needs to flow

around entire charger. Do not set

charger on flammable materials like

carpeting, upholstery, paper, card-

board, etc. Charger may damage

leather and melt plastic and rubber.

HELP US HELP YOU --

Remember:

Place charger as far away from the

battery being charged as the charger

cables will permit.

Do not expose charger to rain or

snow,

Never charge a frozen battery. If battery

fluid (electrolyte) becomes frozen, bring

battery into a warm area to thaw before

you begin charging.

Never allow battery acid to drip on

charger when reading specific gravity

or filling battery.

Never set a battery on top of the char-

ger.

Never place charger directly above battery

being charged. The gases from the battery

will corrode and damage the charger.

Never touch the battery clamps together

when the charger is on. You could cause

a spark.

Never operate charger if it has received

a hard blow, been dropped, or otherwise

damaged. Take itto a qualified professional

for inspection and repair.

Be sure to position the charger power cord

to prevent it from being stepped on, tripped

over, or damaged.

Never pull out the plug by the cord when

unplugging the charger. Pulling on the

cord may cause damage to the cord or

the plug.

Do not operate the charger if it has a

damaged power cord or plug. Have the

cord replaced.

• Wear complete eye and clothing

protection when working with lead-

acid batteries.

• Make sure that someone is within

range of your voice to come to your

aid if needed while you work with or

are near a lead-acid battery.

• Have plenty of fresh water and soap

nearby for use in case battery acid

contacts your eyes, skin, or clothing. If

this happens, wash immediately with

soap and water. Then get medical at-

tention.

• Avoid touching your eyes while

working with a battery. Acid particles

(corrosion) may get into your eyes. If

this occurs, flush eyes immediately

with running cold water for at least 10

minutes. Then immediately get medi-

cal attention.

• Remove all personal metal items

from your body such as rings, brace-

lets, necklaces and watches, while

working with a lead-acid battery. A bat-

tery can produce a short circuit current

high enough to weld a ring (or the like)

to metal, causing a severe burn.

• Take care not to drop any metal tool

or metal object onto the battery. This

may spark or short circuit the battery

or another electrical device that may

cause an explosion.

• Always operate the battery charger in

an open, well-ventilated area.

• Never smoke or allow a spark or flame

in the vicinity of the battery or engine.

Batteries generate explosive gases.

• Neutralize any acid spills thoroughly

with baking soda before attempting to

clean up.

It is important that you read and follow these guidelines while you are preparing to charge

the battery.

• Make sure that you have a 6 or 12 volt

lead-acid battery. Determine voltage of

battery by referring to vehicle owner's

manual or the battery markings. Charge

battery initially at charger's lowest rate.

• Clean the battery terminals. Be careful to

keep corrosion from getting in or around

your eyes or on your hands.

• Wear safety glasses. See additional "Per-

sonal Safety Precautions" on page 4.

• If required, for batteries with removable

vent caps, add distilled water to each cell

until the battery acid reaches the level

recommended by the manufacturer. This

will help purge excessive gases from the

cells. Be careful notto overfill. If you have

a sealed battery with non-removable vent

caps, no action is necessary.

• Take time to read all of the battery

manufacturer's specific precautions,

such as removing or not removing vent

caps while charging, and recommended

rates of charge.

• Be sure that the area around the bat-

tery is well ventilated while it is being

charged. Gas can be forcefully blown

away by using a piece of cardboard or

other nonmetallic material as a fan.

• If it is necessary to remove the battery

from the vehicle to charge it, always

remove the grounded terminal from the

battery first. Turn off all vehicle acces-

sories to avoid sparks from occurring.

• NOTE: A marine (boat) battery installed

in a boat must be removed and charged

USING ENGINE START

Your battery charger can be used to jump

start your car if the battery is low. Fol-

low these instructions on how to use the

ENGINE START feature.

iMPORTANT: Follow all safety instructions

and precautions when charging your bat-

tery. Wear complete eye protection and

clothing protection. Charge your battery

in a well-ventilated area.

iMPORTANT: Using the ENGINE START

feature WITHOUT a battery installed in

the vehicle could cause damage to the

vehicle's electrical system.

1. For battery connections, see page 6

and follow instructions 1 - 6 of CHARG-

ING BATTERY IN THE VEHICLE. With

the charger plugged in and connected

to the battery of the vehicle, set the

CHARGE RATE to 80A START. Only the

80A START, CHARGING, and VOLT-

AGE LEDs should be lit, unless the 6V

REGULAR battery type has been se-

lected. In that case, the 6V REGULAR

LED will also be lit.

2. Crank the engine until it starts or 5 sec-

onds passes. If engine does not start,

wait 3 minutes before cranking again.

3. After the engine starts, unplug the power

cord before disconnecting the output

clamps from the battery.

4. Clean and store the charger in a dry

location.

NOTE: During the starting sequence listed

above, the charger is set to one of three

states.

1. Wait for cranking - The charger waits

until the engine is actually being cranked

before delivering 80 amps for engine

start. The charger delivers charge at a

rate of up to 12 amps while waiting and

will reset if the engine is not cranked

within 15 minutes. (If the charger resets,

it sets itself for a 2A charge and 12V

REGULAR battery.) While waiting for

cranking, the digital display shows

the battery voltage (it can't be set to

percent).

2. Cranking - When cranking is detected,

the charger will automatically deliver up

to its maximum output (at least 80A)

POWER-UP IDLE TIME LIMIT

If no switch button is pressed within 15

minutes after the battery is first powered

up, the charger will automatically switch

from tester to charger, if a battery is

connected. In that case, the battery will

be set for the 2A charge rate and 12V

REGULAR battery type.

TESTER WITHOUT TIME LIMIT

If either the DISPLAY MODE or BAT-

TERY TYPE button is pressed within

the first ten minutes after the battery is

powered up, the battery will remain a

tester (not a charger) indefinitely, unless

a charge rate is selected.

TESTING AFTER CHARGING

After the battery has been changed from

tester to charger (by selecting a charge

rate), it remains a charger. To change

the battery back to a tester, press the

CHARGE RATE switch until all charge

rate LEDs are off.

TESTER STATUS LEDs

When the 71225 is operating as a bat-

tery tester, the status LEDs light under

the following conditions:

• The CHARGED (green) LED will light if

a charged battery is tested.

• The CHARGING (yellow) LED does not

light in the battery test mode.

• The CHECK (red) LED lights unless a

properly connected battery is detected.

• When the tester display mode is set to

VOLTAGE, the CHARGED and CHARG-

ING LEDs won't light.

INITIAL PERCENT CALCULATION

When a battery % is calculated for the

first time after connecting a battery, the

digital display will show three dashes

("---") for a period as long as several

seconds while the tester analyzes the

battery.

NOTES FOR TESTING BATTERY %

A recently charged battery could have a

temporarily high voltage due to what is

known as "surface charge". The voltage

of such a battery will gradually drop during

the period immediately after the charging

system is disengaged. Consequently, the

tester could display inconsistent values

for such a battery. For a more accurate

reading, the surface charge should be

removed by temporarily creating a load on

the battery, such as by turning on lights or

other accessories.

The battery % ranges from 0 to 100.

The battery tester is only designed to test

batteries. Testing a device with a rapidly

changing voltage could yield unexpected

or inaccurate results.

Completinganinterrupted charge: if

the charging process has been interrupted

and restarted after the charger displays a

battery % of 85 or more, the charger could

go straight to Maintain Mode (see page

8). However, if the original charge was

started using 3OA, the charge can often

be completed using the 2A rate.

A minimal amount of care can keep your battery charger working properly for years.

1. Clean the clamps each time you are finished charging. Wipe off any battery fluid

that may have come in contact with the clamps to prevent corrosion.

2. Coil the input and output cords neatly when storing the charger. This will help pre-

vent accidental damage to the cords and charger.

3. Occasional cleaning of the case of the charger with a soft cloth will keep the finish

shiny.
