NEVER charge a frozen, damaged or leaking battery.
Keep other persons, children and pets away from the batteries and your
charger during its operation to avoid serious injury, death, fire or explosion.
If necessary to remove a battery from a boat to charge, always remove the
grounded negative terminal from the battery first. Make sure all accessories
in the boat are off, as to avoid causing an arc.
Be sure the area around the charger and batteries is well ventilated while the
battery is being charged.
Neutralize with baking soda any electrolyte that spills on a vehicle or in the work
area. After neutralizing, rinse the contaminated area clean with water
Regularily clean the battery terminals. Be careful to keep corrosion from coming
in contact with eyes.
For flooded batteries with removable caps, ONLY ADD DISTILLED WATER in
each cell until electrolyte reaches levels specified by the battery manufacturer. Do
not over fill. For a maintenance free battery without removable caps, such as valve
regulated lead acid batteries, carefully follow manufacturer’s recharging instructions.
Study all battery manufacturers’ specific precautions; warnings and instructions
while charging and recommended rates of charge. Never charge a battery with
missing safety vent caps.
Do not overcharge batteries trying to charge non 12 volts flooded or AGM lead
acid batteries.
Place the charger as far away from the batteries as possible .
Never place the charger directly above a battery being charged; gases or fluids
from the battery will corrode and cause damage to the charger.
Do not operate the charger in an enclosed area or in an area with restricted
ventilation.
Never allow battery acid to drip on charger when reading electrolyte specifi
gravity or filling a battery.
Do not place a battery on top of the charger.
Do not install the charger on or over combustible surfaces.

Engine Start Battery
Installation
When connecting each jacketed battery charger cable, make sure it is connected
to only one 12 VDC battery and observe the polarity and color of all connections:
• Red Wire to the “+” (Positive) Battery connection
• Black Wire to the “-” (Negative) Battery connection
The black wire can never be connected to a terminal with red wires and vice
versa.
Important: The pair of red and black wires in 1 cable jacket MUST GO TO
THE SAME 12VDC battery.
