IMPORTANT SAFETY INSTRUCTIONS

WARNING – RISK OF EXPLOSIVE GASES

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

GENERATE EXPLOSIVE GASES DURING NORMAL OPERATION. FOR THIS REASON, 

IT IS IMPORTANT THAT YOU FOLLOW THESE INSTRUCTIONS EACH TIME YOU USE 

THE CHARGER.

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

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

of the battery. Review the cautionary markings on these products and on the engine.
WARNING:

 Pursuant to California Proposition 

65, this product contains chemicals known to 

the State of California to cause cancer and 

birth defects or other reproductive harm. 

Wash hands after handling.

Use the battery charger on LEAD-ACID and

AGM-type rechargeable batteries with

recommended rated capacities of 12Ah (6V)

and 22-59Ah (12V), as used in automobiles, 

trucks, tractors, airplanes, vans, RVs, trolling

motors, etc. This charger is not intended to 

supply power to low-voltage electrical

systems, other than in a motor-starting 

application.

WARNING:

 Do not use battery charger with

dry cell batteries that are commonly used with

home appliances. These batteries may burst

and cause injury or damage to property.

Use only attachments recommended or sold

by the battery charger’s manufacturer. Use

of non-recommended attachments may

result in a fire, electric shock or injury.

Locate the battery charger’s power cord so

it cannot be stepped on, tripped over, or

subjected to damage or stress.

Do not operate the charger if it has received

a sharp blow, been dropped, or otherwise

damaged in any way. Take it to a qualified

professional for inspection and repair.

Do not disassemble the charger. Take it to a

qualified professional when service or repair

is required.

Keep out of reach of children.

To reduce the risk of electric shock, unplug

the charger from the outlet before

attempting any maintenance or cleaning.

Do not use an extension cord.

Always charge the battery in a well-

ventilated area

Do not set the charger on flammable

materials, such as carpeting, upholstery,

paper, cardboard, etc.

WARNING: RISK OF EXPLOSIVE GAS.

Operate the charger as far away from the

battery as DC charger cables permit.

Do not expose the charger to rain or snow.

NEVER charge a frozen battery.

NEVER set a battery on top of the charger.

NEVER place the charger directly above a

battery being charged. Gases from the

battery will corrode and damage the charger.

NEVER touch the battery clamps together

when the charger is energized.

When disconnecting the battery charger, pull

by the plug, not by the cord. Pulling on the 

cord may cause damage to the cord or plug.

Do not operate the charger with damaged

cord or plug.

NEVER allow battery acid to drip onto the

charger.

NEVER overcharge a battery.

PERSONAL SAFETY PRECAUTIONS

Wear complete eye protection and

protective clothing when working near

lead-acid batteries. Always have someone

nearby for help.

Have plenty of fresh water, soap and baking

soda nearby for use, in case battery acid

contacts your eyes, skin, or clothing. Wash

immediately with soap and water and seek

medical attention.

If battery acid comes in contact with eyes,

flush eyes immediately for a minimum 10

minutes and get medical attention.

Neutralize any acid spills thoroughly with

baking soda before attempting to clean up.

Remove all personal metal items from your

body, such as rings, bracelets, necklaces

and watches. A battery can produce a short

circuit current high enough to weld a ring to

metal, causing a severe burn.

NEVER smoke or allow a spark or flame in

the vicinity of the battery or engine.

Do not drop a metal tool onto the battery.

If it is necessary to remove the battery from

the vehicle to charge it, always remove the

grounded terminal first.
