Seven Hour • Eight Battery Universal Charger

Your RadioShack Seven Hour
Battery Universal Charger can charge
five different types of standard nickel­cadmium batteries — AAA, AA, and 9V
in 4–10 hours; C and D in 8–9 hours.
(High-capacity nickel-cadmium batter­ies take longer.) Y ou can insert a pai r
of batteries into each of the charger’s
four battery chambers, letting you
charge different types of batteries at
the same time.

Each chamber can c harge one pair of
AAA, AA, C, or D batteries. The con­nectors inside the charger let you also
charge one or two 9V batteries at a
time.

Your charger has these features:

OPERATION

General Charging Hints

• Completely discharge batteries
before you charge them. Repeat­edly charging batteries that are
not fully discharged can shorten
their useful life.

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

• If you are charging two 9V b atter­ies, you can also charge other
types of batteries (except D bat­teries) in the two other chambers.

• You ca nnot charge a single AAA,
AA, C, or D battery in a battery
chamber at a time. You
charge a pair of batteries in one
chamber while the other cham­bers are empty.

• Do not overcharge batteries. P ro­longed overcharging can shorten
the batteries’ useful life. See the
chart on Page 3.

Cautions:

• Never mix different-sized batteries
in the same chamber, or put a dis­charged battery in the same
chamber as a charged battery.

• Do not try to charge a battery of a
size other than those listed by
inserting it in the chamber or by
connecting the battery’s terminals
to the charging contacts with a
piece of metal.

• Charge batteries in an area
between 60 and 85°F. Batteries
do not fully cha rge when they a re
cold. If the area is too warm, the
batteries can permanently lose
their ability to charge.

To charge one or two 9V batteries,
push their terminals onto th e con­nectors inside the charger.

Note: If the indicators do not light,
be sure you installed the batteries
with the proper polarity (+ and –).
If you installed them correctly and
the indicators still do not light,
unplug the charger, remove the
batteries, and clean the batteries’
and charger’s contacts. Then rein­stall the batteries and plug in the
charger. If the problem persists,
one of the batteries you are trying
to charge might be faulty.

3. After the specified charging time
(see below), unplug the adapter
from the AC outlet and remove the
batteries.
