FEATURES

Your RadioShack Universal Ni-Cd/Ni-MH Charger can ful­ly charge up to five different sizes of Ni-Cd (nickel-cadmi­um) and Ni-MH (nickel-Metal Hydride) batteries in only 14
or 18 hours. It can charge AAA, AA, C, D and 9V batteries.

Your charger's features include:
Multiple Charging Circuits — allow you to charge up to

four AAA, AA, C, or D Ni-Cd or Ni-MH batteries, and up to
two 9V batteries.

Automatic Charging Current Selection — selects the
best charging current for each battery size.

Reverse Polarity Protection — protects the charger and
batteries against incorrectly installed batteries.

Built-in Transformer — lets you connect the charger to
AC power.

Safety Timer Shut-Off — turns off the charger to prevent
overcharging AAA, AA, C, or D batteries.

Two Charging Indicators — light when the batteries are
charging (one for each chamber).

9V Battery Terminal — let you charge up to two 9V bat­teries at a time.

Ni-Cd/Ni-MH Switch — lets you set the charger for the
type of batteries you are charging.

IMPORTANT SAFETY
INSTRUCTIONS

SAVE THESE INSTRUCTIONS - This manual contains

important safety instructions for battery charger Cat. No.
23-334 .

A

1. Before using the battery charger, read all the instruc­tions and cautionary markings in this manual and on
the battery charger, on the batteries to be charged,
and on the products that use the batteries.

2. Warning: To reduce the risk of injury:

• Charge only Ni-Cd and Ni-MH batteries with this

charger. Other types of batteries might burst,
causing personal injury and damage.

• Unplug the charger from the AC outlet before

attempting any maintenance or cleaning.

• Do not disassemble the charger; take it to a quali-

fied service technician when service or repair is
required. Improper 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.

3. 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 received a

sharp blow, or been dropped or damaged in any
way. Take it to a qualified service technician for
repair.

4

• To reduce the risk of damage to the AC plug and
cord, disconnect the charger by pulling the plug
rather than the cord.

• Do not use an extension cord. Its use could result
in fire or electric shock.

• Do not operate the charger if the cord or plug is
damaged. Have the charger repaired. Never alter
the provided AC cord or plug. If it does not fit into
the AC outlet, have a qualified service 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 HINTS

• It is normal for the batteries to become warm while
charging.

• Charge batteries in an area between 32° and 113°F
(0° and 45°C). If the area is too warm, the batteries
can permanently lose their ability to charge.

• Do not try to charge batteries other than tho se listed
in this manual, or use procedures other than those
described in this manual.

3. To charge two AA, AAA, C, or D batteries of the
same type (Ni-Cd or Ni-MH), place them into the left
or the right chamber as indicated by the polarity sym­bols (+ and –) marked inside each chamber.

6

• You can charge two different sizes (AA and D, for
example) of batteries of the same type (Ni-Cd or
Ni-MH) in the left and right chambers, as long as
both batteries in each chamber are the same size.

• You can charge four AAA, AA, C or D batteries at
the same time while the 9V battery chambers are
empty.

4. To charge a 9V battery, insert it into one of the termi­nals inside either chamber. To charge a second 9V
battery at the same time, insert it into the remaining
terminal.

Note: You can charge a 9V battery in one chamber
and charge another size battery in the remaining
chamber at the same time.

5. Insert the plug of the charger into a standard AC out­let. CHARGE lights for each chamber containing a
battery.

When AAA, AA, C, or D batteries are fully charged,
CHARGE turns off. (This is the end of the charging
cycle.)

Note: The 9V charging channel has no automatic
turn off feature. Be sure you do not exceed the times
listed in “Charging Cycle Times” on Page 8, or the
batteries' capacity could be reduced.

6. When you finish, unplug the charger from the AC
outlet, then remove the batteries from the charger.

CARE AND MAINTENANCE

Your

RadioShack Universal Ni-Cd/Ni-MH Charger

example of superior 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 immediately. Liquids might contain
minerals that can corrode the electronic
circuits.

Use and store the charger only in normal
temperature environments. Temperature
extremes can shorten the life of electronic
devices, damage batteries, 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.
Dropping 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 chemicals, cleaning solvents, or
strong detergents to clean the charger.

Modifying or tampering with the charger’s internal com­ponents can cause a malfunction and might invalidate
its warranty. If your charger is not performing as it
should, take it to your local RadioShack store for assis­tance.
