rechargeable Ni-Cd or Ni-MH batteries in the
same charging bay.

Thank you for purchasing a RadioShack Fast Ni-Cd/Ni-MH Battery Charger. Your charger
charges three different sizes of nickel-cadmium (Ni-Cd) or nickel-metal hydride (Ni-MH)
batteries — AA and AAA within 2.5 hours, and 9V within 10.5 hours. You can charge up to
eight AA/AAA batteries of the same type, or two 9V batteries, in the charger’s four battery
bays at the same time.

Alkaline Batt ery Protection — prevents your
charger from charging alkaline batteries.

Delta V and Zero Slope Peak Voltage Full
Charge Detection — prevents overcharging a

fully charged AA or AAA battery. A back-up timer
provides additional overcharging protection.

General Charging Guidelines

• Never mix AA and AAA batteries in the
charger, or put a discharged battery and a
charged battery in the same bay.

• 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 60° and 85°F (16°
and 29°C). Batteries do not fully charge
when cold. If thecharging conditions are too
warm, the batteries can permanently lose
their rechargeable properties.

Charging Batteries

Before connecting thecharger 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.

right 9V bay and AA/AAA batteries in
the left bay.

• You cannot charge only one AA or AAA
battery in one battery bay. Y oumust
always charge a pair of the same size
and type batteries in one bay if the
other bays are empty.

CHARGING BATTERIES

The charger has 4 charging bays. Each bay
provides charging spaces for two AA and
two AAA batteries in alternating spaces. The
AA batteries fit between flat spring contacts
while the smaller AAA batteries fit between
flat spring contacts along the compartment’s
upper side and spring metal loops along the
lower edge of the compartment.

1. Lift the battery charger’s cover.

2. Place 2 AA or AAA batteries in BAY 1
according to the polarity symbols
(+ and –) marked inside the bay. If you
have more than 2 batteries to be
charged at a time, fill BAY 2 next, and
so on.

To charge 9V batteries, place the first
battery in the 9V channel across BAY 1
and BAY 2. Slide the battery’s connec­tors onto the terminals on the outside
wall of the channel. Place a second 9V
battery in the channel across BAY 3
and BAY 4.

3. Slide

BAY to select the number of bays

being used specifically for AA/AAA
batteries.

 Ô

4. Insert the AC adapter’s plug into a
standard AC outlet. The indicators on
top of the charger light showing that the
batteriesare charging. Ô

5. When the charging indicators turn off,
the batteries are fully charged. Unplug
the adapter from the AC outlet and

Ô NOTE Ô

• The indicators light steadily while batteries
are charging. If the indicators flash, at least
one of the batteries you are trying to
charge is defective.

• When you charge 9V batteries, the
position of BAY has no effect. The
charger’s built-in timer tracks the state of
charge.

• To charge one 9V battery, use the left
(BAY1 and BAY2) 9V battery channel.

• If the indicators do not light, try one or
more o f the following suggestions.

Check the battery positions in the bay, and
reverse any that are incorrect.

Remove the batteries and clean the
batteries’ and charger’s contacts.

One or more batteries might be defective.
Replace any defective batteries.
