You can fully charge up to eight AA or AAA, four C or D, or two
9 V batteries. Multiple-battery design accommodates NiMH and
NiCd batteries. This is an economical power solution for users of
portable devices with removable batteries.
The universal 100-240 V AC and 12-16 V DC inputs
are ideal for traveling and charging anywhere.

flash green and red to indicate that
power is connected.
(B) Battery Charging
Insert up to four pairs of AA or AAA
1
batteries or four individual C or D
batteries into the corresponding bays
as indicated by the labels and the
polarity symbols (+ and -) marked inside
each bay. Connect 9 V batteries to the
terminals in the center bay.
You can pair one AA with one AAA battery to
charge them as a pair in the same channel.

The LED charging indicators turn red
per channel when the batteries are
charging and green when the batteries
are fully charged.
Note: The LEDs flash red if you insert a disposable
battery such as an alkaline. If you see the LEDs
flashing red, remove the battery.

When charging is complete, unplug
the charger from the outlet, and then
remove the batteries from the charger.
To charge a single AA battery, insert it into
one of the C/D charger bays. However, to
charge a AAA you must pair it with a AAA or
AA battery

IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS
Be sure to observe the following important
precautions whenever using the charger and
adapter.
Never try to open the case of the charger
or attempt your own repairs. High-voltage
internal components present the risk of
electric shock when exposed.
Keep the charger and adapter away from
water and other liquids. Never let them get
wet. Moisture can cause fire and electric
shock.
Should you ever notice smoke or a strange
odor coming out of the charger, immediately
unplug the power adapter from the outlet.
Using the charger under these conditions
can cause fire and electric shock.
Unplug the power adapter from the outlet
and clean the area around the electrical
contacts of the plug when necessary. Dust
around the contacts can cause a fire.
Page 13
AC ADAPTER PRECAUTIONS
Never use an electrical outlet whose voltage
is outside the rating marked on the AC
adapter. Doing so can cause fire or electric
shock. Use only the supplied power adapters
for the chargers.
Be careful not to cut or otherwise damage
the power adapter cord, and do not place
heavy objects on it. A damaged adapter cord
can cause fire or electric shock.
Never try to modify the AC adapter power
cord, or subject it to severe bending, twisting
or pulling. Doing so can cause the risk of fire
and electric shock.
Never touch the AC adapter with wet hands.
Doing so can cause electric shock.
Do not overload extension cords or wall
outlets. Doing so can cause fire and electric
shock.
This product is for indoor use only. Do not
expose the charger to rain or snow.
To reduce the risk of damage to the electrical
Page 14
plug and cord, disconnect by pulling the plug,
not the cord.
Make sure the cord is located properly so
that it will not be stepped on, tripped over, or
subjected to damage.
To reduce the risk of electric shock, unplug
the charger from the outlet when not in use
and before attempting to clean it.
Do not use solvents to clean the unit. They
may damage the surface and the plastic
parts of the unit. Clean the unit gently with
only a soft dry cloth.
Keep this product away from children.
BATTERY HANDLING PRECAUTIONS
Incorrect handling or misuse of batteries can
cause them to leak or burst and damage your
charger. Be sure to note the following important
precautions to avoid problems with batteries.
Use only NiMH or NiCd dry cell batteries with
the charger. Do not charge any other kind of
batteries, including alkaline batteries, since
Page 15
they may burst and cause personal injury
and damage.
Always make sure that the plus (+) and
minus (-) terminals of the batteries are
facing correctly, corresponding to the
markings on the charger itself. Improper
loading of batteries creates the danger of
personal injury or damaging nearby objects.
Do not expose batteries to direct heat or
dispose of them by burning. Doing either can
cause an explosion.
Do not operate the charger in an
environment with temperatures higher than
104¾F (40¾C) due to the risk of electrolyte
leakage, overheating, and battery damage.
It is normal for batteries to become warm as
they charge or discharge.
If electrolyte material touches your eyes,
immediately wash your eyes with running
cold water, and seek medical attention.
Please recycle dead batteries, and preserve
our environment.
