FEATURES
Your RadioShack 5-Hour/8-Hour AA/AAA Ni-
Cd/Ni-MH Battery Charger charges nickel-
cadmium (Ni-Cd) batteries in about 5 hours or
nickel-metal-hydride (Ni-MH) batteries in
about 8 hours. You can charge two or four AA
or AAA batteries of the same type and capac-
ity. Or you can charge one 9V battery with the
charger’s 9-volt battery terminals. Charging a
9V battery takes about 9 hours.
Your charger’s features include:

INSTRUCTIONS
This manual contains important safety and
operating instructions for your charger.
Before you use the battery charger, read all
instructions and cautionary markings on the
charger, the batteries to be charged, and the
products that use the batteries.
Warning: To reduce the risk of injury, charge
only Ni-Cd or Ni-MH batteries with this charg-
er. Other types of batteries might burst, caus-
ing personal injury and damage.
Safety Instructions
• Do not expose the charger to rain or
excessive moisture.
• Any attachments not intended for use
with this battery charger can result in a

risk of fire, electric shock, or personal
injury.
• Never operate the charger if it has
received a sharp blow, or been dropped
or damaged in any way. Take it to your
local RadioShack store for service.
• Do not disassemble the charger. Have it
serviced or repaired by qualified Ra-
dioShack service personnel only. Incor-
rect assembly can result in a risk of elec-
tric shock or fire.
• To reduce the risk of electric shock,
unplug the charger from the outlet before
routine maintenance or cleaning.
• Do not use an extension cord. Its use
could result in fire or electric shock.
• If the AC plug does not fit in the AC out-
let, have a qualified technician install the
proper outlet. Improper connection can
result in an electric shock.

• Never use the charger as a DC power
source for any electrical equipment.
OPERATION
General Charging Guidelines
• Completely discharge Ni-Cd batteries
before you charge them. Repeated par-
tial discharging and recharging can
shorten their useful life. This does not
apply to Ni-MH batteries.
• It is normal for batteries to become warm
while charging.
• Batteries in the charger at the same time
must be of the same type (Ni-Cd or Ni-
MH) and capacity (standard or high-
capacity).
• The charger has two channels. Both the
left and right channels have two positions
for AAA and two positions for AA batter-
23-335.fm Page 6 Monday, September 11, 2000 10:57 AM

ies. Each channel also has its own red
CHARGE indicator that lights when bat-
teries in that channel are charging.
• You cannot discharge/charge one 9V
battery and AA/AAA batteries at the
same time. However, you can discharge/
charge a pair of AA batteries in one
channel and a pair of AAA batteries of
the same type and capacity in the other
channel at the same time.
• You cannot discharge/charge only one
AA or AAA battery in each battery chan-
nel. You must always discharge/charge a
pair of batteries of the same size, type,
and capacity in one channel if the other
channel is empty.
Cautions:
• Never put a discharged battery and a
charged battery in the same channel.
• Do not attempt to charge any other

size or type battery than those for
which this charger was designed.
• Charge batteries where the ambient
temperature is between 32° and 113°F
(0° and 45°C). If charging conditions
are too cold, batteries do not fully
charge. If charging conditions are too
warm, the batteries can permanently
lose their rechargeable properties.
Discharging/Charging Batteries
Follow these steps to discharge and then
charge the batteries:
1. To open the cover, grasp the tabs on
both sides of the charger and lift up the
cover.
2. Place two AA or two AAA batteries in the
left channel according to the polarity
symbols (+ and –) marked inside the bat-
tery compartment. If you have more than

two batteries to be discharged/charged
at a time, place two AA or two AAA bat-
teries in the right channel next.
To charge a 9V battery, place it in the 9V
channel. Slide the battery's connectors
onto the terminals on the compartment’s
right side.
Caution: Before connecting the charger
to AC power, be sure all batteries are
correctly installed according to polarity.
Incorrectly installed batteries (polarity
reversed) will not charge and can be
damaged.
