property. In case of skin contact, immediately rinse
with water. If redness, pain or irritation occurs seek
medical attention. In case of eye contact, rinse
immediately with clean water and seek immediate
medical attention.
• When disposing of batteries, follow the instructions
given in the section "Protecting the environment".
• Add distilled water in each cell until the battery
acid reaches the level specified by the battery
manufacturer. This helps to purge excess gas from
the cells. Do not overfill. For a battery without
cell caps (maintenance free), carefully follow the
manufacturer's charging instructions.
• Study all the battery manufacturer's specific
precautions, such as removing or not removing cell
caps while charging, and the recommended charging
• Make sure that the initial charging rate does not
exceed the battery manufacturer's requirement.
• Warning! Risk of explosive gas mixtures. Working
in the vicinity of a lead-acid battery is dangerous.
Batteries generate explosive gases during normal
battery operation. For this reason, it is of utmost
importance that each time, before using your
battery charger, you read this manual and follow the
instructions exactly.
• Use of an attachment not recommended or sold by
Black & Decker may result in a risk of fire, electric
shock, or injury to persons.
• An extension cord should not be used unless
absolutely necessary. Use of an improper extension
cord could result in a risk of fire and electric shock,
and will void the warranty.
Dc accessory plug safety
• Warning! NEVER connect this unit to a positive
grounded vehicle by the dc accessory plug.
• Make sure that the vehicle's accessory socket is
clean and free of debris before connecting the unit.
• Warning – risk of fire! If the vehicle accessory
socket fuse opens (blows) when plugging in this
battery charger, do not use this battery charger with
this vehicle accessory socket.
– Do not repeatedly replace the fuse.
– Do not replace the vehicle accessory socket fuse
with one of a higher amperage rating.
– Never attempt to patch the fuse with tin foil or wire.
Any of these actions may cause serious
electrical damage and/or a fire.
Specific safety instructions for using
the unit in wet environments
The housing of this unit is rated to IP67 dust-
proof and waterproof standards. However, it is
recommended that you observe the following:
• Never submerge the unit in water deeper than 1
meter, for time longer than 30 minutes and/or in
BC2WBDAU_Manual_091216.indd 4-5
temperatures other than between 5ºC and 40ºC, or
the unit could sustain permanent damage.
• Never submerge the unit in water unless the bushing
(insulation) of the mains or dc cord is intact.
• Do not allow plug or clamps to be exposed to
the elements for long periods of time; and never
submerge them.
Personal safety
Wear complete eye protection and suitable clothing to
give protection from contact with battery fluid.
Avoid touching the eyes while working with a battery.
Acid, acid particles or corrosion may get into the eyes.
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 circuit
current high enough to cause a severe burn.
Be extra cautious to reduce the risk of dropping a
metal object onto the battery. This might cause sparks
or short-circuit the battery or other electrical part,
which can cause an explosion.

Ensure that all installation and operating instructions
and safety precautions are understood and carefully
followed by anyone installing or using the battery
charger. Follow the steps outlined in the "Important
Safety Instructions" section of this manual.
Mounting the Unit Using the Magnetic
The magnetic discs in the bottom of the unit allow
you to position the battery charger on any flat, secure
metallic surface.
Mounting the Unit Using the Hanging
The hanging hook allows you to position the battery
charger for convenient, hands-free operation.
• When the charger is hung by the hanging hook or
attached using the magnetic discs, do not shake the
charger or object that it is hanging from or attached
to. Do not hang the charger from or attach the
charger to any electrical wires or anything that it is
not secure.
• Only use the hanging hook or magnet discs for
hanging or positioning the charger. The hanging
hook and magnetic discs are not intended to support
additional weight. Do not attach or hang anything
additional to the charger or risk of breakage may
The appliance must only be connected to a 12V
lead-acid battery. Before charging, confirm that
the voltage of the battery is 12V by referring to
the label on the battery or from the information
available relating to its application e.g. car user
Do not use the appliance for charging dry-cell batteries
that are commonly used with home appliances. These
batteries may burst and cause injury to persons and
damage to property.
Warning! Explosive gas may be vented from lead
acid batteries when charging. The battery must be
placed in a well-ventilated area and you must remove
any sources of ignition when conducting charging
• Never place the battery charger directly above the
battery; gases from the battery will corrode and
damage the battery charger.
• Never allow battery acid to drip on the battery
• Position the battery charger as far away from the
battery as the leads will allow. The battery charger
contains switches that may create a spark.
• Do not set a battery on top of the charger.
• Explosive gases may collect near the ground. Locate
the battery charger as high as possible above ground
• Do not use power tools in the charging area.
• Do not smoke or have a naked flame in the charging
• Follow the instructions for connecting and
disconnecting the battery charger leads or battery
Warning! A marine (boat) battery must be removed
and charged on shore. To charge it on board requires
equipment specially designed for marine use. This
appliance is NOT designed for such use.
Vehicles may have electrical and electronic systems
(e.g. engine management systems, mobile phones)
that may be damaged if subjected to high starting
voltages and voltage peaks. Before connecting the
appliance to the vehicle, read the vehicle's owner's
manual to confirm that external charging is allowed.
• Follow these instructions and those published by the
battery manufacturer and vehicle manufacturer.
• Only connect and disconnect the dc output clamps
or ring terminals after removing the supply cord
from the electric socket. Never allow clamps or ring
terminals to touch each other.
• Check the polarity of the vehicle battery terminals
before connecting the appliance. Always disconnect
the negative (black) cable first: followed by the
positive (red) cable.
When charging a battery installed in the circuit follow
the manufacturers instructions for accessing the
battery and the following:
• Do not charge the battery while the engine is
• Be aware that engine components e.g. the coolant
fan may start automatically. Keep hands and body
away from engine components and position the
battery charger and cables to prevent contact.
• Make sure that the battery charger and the cables
are located to prevent damage from closure of doors
and engine compartment covers.
• Make sure that the connections can be made without
touching the metal body or components adjacent to
the battery.
• When using this appliance in proximity to the
vehicle's battery and engine, stand the appliance on
a flat, stable surface and be sure to keep all clamps,
cords, clothing and body parts away from moving
parts of the vehicle.
• If it is necessary to remove the battery from the
vehicle to charge or to clean the terminals, make
sure that all accessories in the vehicle are switched
off, so as not to cause a spark.
• To reduce the risk of electric shock, disconnect the
appliance from any power source before attempting
maintenance or cleaning.
When all the preparations for charging and personal
safety have been completed, proceed as follows:
• For most automotive and similar applications the
battery charger may be connected to the battery
while it is connected to the dc circuit. Follow the
instructions given in "Charging a battery installed in
the circuit".
• If the battery must be disconnected from the circuit
before charging, follow the instructions given in
"Charging a battery disconnected from the circuit".
Warning! A marine (boat) battery must be removed
and charged on shore. To charge it on-board requires
equipment specially designed for marine use.
