6 | Charger Operation
You can charge up to 8 AA/AAA NiMH/NiCd batteries fully.
Multiple-battery design accommodates both AA and AAA NiMH
batteries. This is an economical power solution for high-tech
battery-operated devices.
RAPID CHARGER
OPERATION:
(A) Power Input
For indoor usage,
1Connect the supplied AC adapter's
barrel plug into the charger's rear
power input jack.
2Plug the AC adapter into a standard AC
outlet.
Or, for in-car usage,
1Plug the optional DC car cord into your
vehicle's cigarette lighter, without the
charger attached.
2Connect the charger to the connector
end of the DC car cord.

Charger Operation | 7
(B) Battery Charging
1Insert up to 8 AA/AAA batteries into
the battery chambers as indicated by
the polarity symbols (+ and -) marked
inside each chamber.
2When a battery is fully charged, its icon
will stop flashing, and an Fwill appear on
the fourth level.
(C) Discharge Your Batteries
Periodically discharge batteries to extend battery life.
1Press the white discharge button once
to discharge AA/AAA batteries. The
battery icon will shift up and down while
discharging.
2When batteries are fully discharged,
the battery icon stops shifting. It will
then display the battery capacity while
charging.
Note: If the discharge button is accidentally pressed,
unplug charging unit to stop the discharge process.
A flashing full-battery icon indicates an abnormality. The
charger will stop the charging process if it detects an issue.

*Actual charging time may vary depending on the cell's discharge
level, capacity, and condition. Longer charging time may occur
when the charger is used in temperatures above 95°F (35°C).

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 AC adapter
from the power outlet. Using the charger
under these conditions can cause fire and
electric shock.
Unplug the AC adapter from the power
outlet, and clean the area around the
prongs of the plug when necessary. Dust
around the prongs can cause fire.
Safety Instructions | 11

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 electic shock. Use only the supplied AC
adapter or DC car cord (optional) for the
charger.
Do not allow the AC adapter power
cord to be cut or damaged, and do not
place heavy objects on it. A damaged AC
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 while your
hands are wet. Doing so can cause electric
shock.
Do not overload extension cords or wall
outlets. Doing so can cause fire and
electric shock.
12 | Safety Instructions

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 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 before
attempting cleaning, or when not in use.
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 a soft dry, cloth only.
This product is not recommended for use
by 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
Safety Instructions | 13

with the charger. Do not charge any other
kind of batteries, as 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 objects
nearby.
Do not expose batteries to direct heat or
dispose of them by burning. Doing so can
cause an explosion.
Do not operate the charger in an
environment with temperatures over
104°F (40°C) due to the risk of electrolyte
leakage, overheating, and battery
damage.
The batteries normally become warm as
they discharge.
If electrolyte material touches your eyes,
immediately wash your eyes with running
cold water, and get medical attention.
