FEATURES
Your RadioShack AC Charger is perfect for charging remote-
controlled racing car batteries. It can fully charge a 4.8-volt,
6.0-volt, 7.2-volt, or 9.6-volt nickel-cadmium or nickel-metal
hydride battery pack in as little as one hour! (High-capacity
7.2-volt, 2000 mAh Ni-Cd and 9.6-volt, 1250 mAh Ni-MH bat-
tery packs require 11/2–2 hours to fully charge.)
Your Universal Charger’s features include:
Automatic Battery Type Selection — automatically selects
the battery type when you snap the battery into the charger’s
battery compartment, for foolproof charging.
Charge Indicator — lights when the battery pack is charging,
automatically turns off when the battery pack finishes charg-
ing, and flashes if battery pack fails to charge, indicating a
problem with the battery (the battery is not properly connect-
ed, needs to be replaced, or there is a short, for example).
Short Circuit Protection — prevents damage if the charging
jack is accidentally shorted.
Safety Guard Protection Timer — prevents overcharging
that can damage the battery pack.

IMPORTANT SAFETY
INSTRUCTIONS
SAVE THESE INSTRUCTIONS!
DANGER: TO REDUCE THE RISK OF FIRE OR ELECTRIC
SHOCK, CAREFULLY FOLLOW THESE INSTRUCTIONS.
This manual contains important safety and operating instruc-
tions for this battery charger. Before you use the battery
charger, read all the instructions and cautionary markings in
this manual and on the battery charger, the battery, and the
product that uses the battery.
Warnin
g
: To reduce the risk of injury:
• Charge only nickel-cadmium and nickel-metal hydride
rechargeable batteries. Other types of batteries could
burst, causing personal injury and damage.
• Unplug the charger from the outlet before attempting any
maintenance or cleaning.
• Do not disassemble the charger; take it to a qualified
service technician when service or repair is required. Im-
proper reassembly may result in a risk of electric shock
or fire.
• Do not use an attachment not recommended or sold by
RadioShack as this could result in a risk of fire, electric
shock, or injury to persons.
Caution: To reduce the risk of damage:
• Do not expose the charger to rain or excessive moisture.
• Do not operate the charger if it has been dropped or
damaged in any way. Take it to a qualified service techni-
cian for repair.
• Do not operate the charger with a damaged cord or plug
— replace them immediately. To reduce the risk of dam-
age to the electric plug and cord:
–Make sure the cord is not located where it will be stepped
on, tripped over, or otherwise subjected to damage or stress.
–Disconnect the charger by pulling the cord’s plug rather than
the cord.

OPERATION
Always use a battery pack until it can no longer provide the
necessary power, then recharge it.
Cautions:
• This charger works only with 4.8-volt, 6.0-volt, 7.2-volt
and 9.6-volt nickel-cadmium/nickel-metal hydride cord-
connected or cartridge battery packs. Charging another
type of battery pack could damage the battery pack or
the charger.
• Avoid charging fully-charged battery packs. Doing so
can damage the battery pack or cause it to lose some of
its storage capacity.
• Use the charger only in an area that is at room tempera-
ture (65–80×F). Charging battery packs in hot areas can
permanently reduce the battery pack’s power capacity.
• To protect battery packs, allow them to cool for 20 min-
utes before recharging them.
• Charge only one battery pack at a time.
CHARGING A CORD-CONNECTED
BATTERY PACK
Warnin
g
: Connect or disconnect the battery connector only
when the charger’s AC cord is disconnected. Otherwise, the
battery connector might arc and burn.
1. Insert the battery connector of the battery pack you want
to charge into CHARGING JACK.

Notes:
• If the connector does not fit, turn it over and try again.
Do not force it.
• To charge a 4.8-volt cord-connected battery pack,
plug the small end of the supplied adapter cord fully
into the battery pack’s connector. Then plug the adapt-
er cord’s large end fully into the CHARGING JACK.
2. Insert the battery pack into the charger’s large compart-
ment. Make sure that the battery pack makes contact
with the voltage selector sensor and the two latches at
the bottom of the compartment.
Note: Do not insert a cartridge battery pack while charg-
ing a cord-connected battery pack, otherwise, the cord-
connected battery pack will not charge.
3. Plug the charger’s cord into a standard AC outlet. After a
few seconds, the charger automatically selects the ap-
propriate charging current and charging begins.
Notes:
• The CHARGE indicator lights when the battery pack is
charging and automatically turns off when the battery
pack finishes charging, and flashes if the battery pack

fails to charge.
• If the battery pack you want to charge is a new one or
has not been used for more than 3 months, leave it in
the charger for 24 hours, even if the CHARGE indica-
tor turns off.
• If the CHARGE indicator flashes, check the battery
connection. If it still flashes, the battery pack might
need to be replaced or there might be a short in the
CHARGING JACK. Try charging a different battery
pack. If the charger still does not work, disconnect it
from power and take it to your local RadioShack for
assistance.
• The CHARGE indicator lights flash after five minutes if
a short to the CHARGING JACK is detected.
4. When the CHARGE indicator turns off, unplug the charg-
er’s AC cord from the outlet, then disconnect the battery
pack.

CARE AND MAINTENANCE
Your RadioShack AC Universal Charger is an example of su-
perior design and craftsmanship. The following suggestions
will help you care for your charger so you can enjoy it for
years.
Keep the charger dry. If it gets wet, wipe it dry im-
mediately. Liquids might contain minerals that
can corrode the electronic circuits.
Use and store the charger onlyin normal temper-
ature environments. Temperature extremes can
shorten the life of electronic devices, and distort
or melt plastic parts.
Keep the charger away from dust and dirt, which
can cause premature wear of parts.
Handle the charger gently and carefully. Drop-
ping it can damage circuit boards and cases and
can cause the charger to work improperly.
Wipe the charger with a damp cloth occasionally
to keep it looking new. Do not use harsh chemi-
cals, cleaning solvents, or strong detergents to
clean the charger.
Modifying or tampering with the charger’s internal compo-
nents can cause a malfunction and might invalidate its war-
ranty. If your charger is not performing as it should, take it to
your local RadioShack store for assistance.
