USE THE FOLLOWING PRECAUTIONS WHEN YOU WORK NEAR
LEAD-ACID BATTERIES:
• Someone should be within range of your voice or close enough to
come to your aid if you have an accident.
• Have plenty of fresh water and soap nearby in case battery acid
contacts skin, clothing, or eyes.
• Wear complete eye protection and protective clothing. Avoid touching
your eyes while working near a battery. If battery acid contacts your
skin or clothing, wash immediately with soap and water. If acid enters
an eye, immediately flood the eye with running cold water for at least
ten (10) minutes and seek medical attention as soon as possible.
• Be extra cautious when handling metal tools around a battery. If you
drop a metal tool near a battery it might spark or create a short circuit
between the battery terminals and some other metal part. Either event
may cause a dangerous electrical shock hazard, a fire, or even an
explosion, resulting in property damage, personal injury, or death.
• Never smoke or allow an open spark or flame in the vicinity of the
battery or engine.
• Remove all personal items made of metal, 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 metal ring or other piece of jewelry, causing a severe burn.
• This battery charger is for charging LEAD-ACID BATTERIES
ONLY. DO NOT USE THE BATTERY CHARGER FOR DRY-
CELL BATTERIES THAT ARE COMMONLY USED WITH HOME
APPLIANCES. THESE TYPES OF BATTERIES MAY BURST AND
MAY CAUSE PROPERTY DAMAGE, PERSONAL INJURY OR
DEATH.
•NEVER charge a frozen battery.
BEFORE CHARGING
• To avoid an electric arc (or spark), turn off or disconnect all of the
accessories in the boat or vehicle. Always remove the cable that is
connected to grounded terminal from battery first.
• Make sure the area around the battery is well-ventilated while the
battery is being charged. If necessary, use a non-metallic material to
fan away the gas in the area.
• If necessary, clean the battery terminals. Be careful to keep the
corrosion and other debris from coming in contact with your skin or
eyes.
• If the battery is not a sealed battery, add distilled water to each cell (if
necessary) until the battery acid solution reaches the level specified by
battery manufacturer. Do not overfill. For a battery without cell caps,
such as a valve regulated lead-acid battery (VRLA), carefully follow
the battery manufacturer’s charging instructions.
• Before charging, carefully read the battery manufacturer’s specific
precautions and recommended rates of charge.
• Determine the voltage of the battery by referring to the boat’s or
vehicle’s owner’s manual and make sure that the battery charger has
compatible voltages.
• If using an extension cord, always connect to the battery
charger first, before connecting to an electrical outlet. When
disconnecting, always disconnect from the electrical outlet first.
Make sure the electrical outlet is a 120VAC GFCI (Ground Fault
Circuit Interrupt) outlet.
LOCATING BATTERY CHARGER
• Locate the battery charger as far away from the battery as
possible.
• Never place the battery charger directly above the battery; gases
from battery will corrode and damage battery charger.
• When reading electrolyte specific gravity or filing battery, never
allow battery acid to come in contact with the battery charger.
• Do not operate the battery charger in a closed-in area or an area
with restricted ventilation.
• Do not set a battery on top of battery charger.
