Thank you for purchasing a RadioShack 

Universal Charger. It can quickly charge 

4.8V, 6V, 7.2V, and 9.6V Ni-Cd and Ni-MH 

cord-connected or cartridge battery packs. It 

also charges 9V rechargeable batteries.

 jack on the side of the 

charger. Then plug the adapter into a 

standard AC outlet. The POWER LED lights. 

If the POWER LED does not light, make 

sure the AC/DC adapter and the charger are

To charge a cord-connected battery pack, 

insert the battery connector of the battery 

pack into connector, and insert the battery 

pack into the charger’s large compartment. 

Make sure that the battery pack contacts 

with the voltage selector sensor and the two 

latches at the bottom of the compartment.

The CHARGING LEDs flash in turn.

If all the CHARGING LEDs flash at the same 

time, check the battery connection and re-

connect the battery pack to the charger. If 

the problem persists, the battery pack might 

need to be replaced or there might be a 

short in the Connector. 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.

If the connector does not fit, turn it over and 

try again. Do not force it.

To charge a standard cartridge battery 

(pack), simply place it into the battery 

compartment according to the 

corresponding symbols marked inside.

To charge a 4.8-volt cord-connected battery 

pack, fully plug the small end of the adapter 

cord (not supplied) into the battery pack’s 

connector. Then plug the adapter cord’s 

large end fully into Connector.

Although you can charge a 4.8V cord-

connected battery pack and a 9V 

rechargeable battery simultaneously, you 

cannot mix two different battery packs (cord-

connected or cartridge battery pack) for 

charging.

When the battery pack is fully charged, all 

CHARGING LEDs light steady. Unplug the 

charger and remove the battery pack.

POWER LED — 

indicates the 

charger is 

connected 

correctly to power.

Five Red CHARGING LEDs 

— indicate the status of the 

battery being charged.

Automatic Battery Type Selection — 

automatically selects the battery type when 

you place the battery into the charging 

compartment.

Bad Battery Detection – 

prevents the charger from 

charging bad batteries.

Short Circuit Protection – 

prevents the charger and 

batteries from damage.

Safety Timer Shut-Off – turns off 

the charger to prevent overcharging 

the battery.

Reverse Polarity Protection – protects the charger and 

batteries against incorrectly installed batteries.

• You must use a Class 2 power 

source that supplies 12V DC and 

delivers at least 1600 mA. Its center 

tip must be set to positive and its 

plug must fit the charger’s DC 12V 1600mA 

jack. The supplied adapter meets these 

specifications. Using an adapter that does 

not meet these specifications could damage 

the charger or the adapter.

• Always connect the AC adapter to the 

charger before you connect it to AC power. 

When you finish, disconnect the adapter 

from AC power before you disconnect it from 

the charger.

• Charge batteries/battery packs in an area 

between 32

°

 to 113

°

 F (0

°

 to 45

°

C). If the 

area is too cold, the batteries can 

permanently lose their ability to charge. If the 

area is too warm, the batteries will not be 

fully charged.

• It is normal for batteries/battery packs to 

become warm while charging.

• To protect batteries/battery packs, allow 

them to cool before recharging them.

• If you mix a 9V rechargeable battery with a 

4.8V cord-connected battery pack for 

charging, all CHARGING LEDs keep 

flashing even though the 4.8V cord-

connected battery pack is fully charged.
