process).
ANALYZE.
2. Press
The charger displays the estimated
charge level, with
the
amount-ofcharge symbol and
the numeric characters showing the
voltage.
Notes:
• The amount-of-charge shown is
based on the normal discharging
curve of a fully charged battery. It
might be inaccurate if the battery
being checked was not fully
charged before it was last used.

23-410.fm Page 6 Friday, August 6, 1999 2:54 PM
• If the battery is unsuitable for
charging,
appears on the display. Do not attempt to charge a
bad battery. At the end of a nickelcadmium or nickel-metal hydride
battery’s useful life, it must be
recycled or disposed of properly.
Contact your local, county, or
state hazardous waste management authorities for information
on recycling or disposal programs
in your area. Some options that
might be available are: municipal
curbside
collection,
drop-off
boxes at retailers such as your
local RadioShack store (nickelcadmium only), recycling collection centers, and mail-back programs.
• The checking process drains current from batteries. Therefore,
repeatedly checking the same
batteries decreases their voltage.
3. To check another battery, repeat
Steps 1 and 2. To charge the battery, see “Charging AA/AAA/C/D
Batteries.”

23-410.fm Page 8 Friday, August 6, 1999 2:54 PM
Note: The charger can activate or revitalize some chemically dormant batteries. If you have new batteries (or
batteries that have not been used for a
long time) that cannot be fully charged
(charged to more than 60% of battery
capacity) singly, recharge them three or
four at a time, then discharge them completely through normal use. Repeat this
process five times. Then, if the batteries
will still not fully charge singly, this
means you will always have to charge
them three or four at a time.
CHARGING A 9V
BATTERY
Refer to the graph on Page 6 for charging times.
1. After connecting power to the
charger, simply push the terminals
of the 9V battery onto the connectors inside the charger, matching the
polarity symbols marked next to the
connectors. The charger begins
charging the battery and the 9V
charging indicator flashes.
Notes:
• The cover does not need to be
closed to charge the 9V battery.
• You can charge up to 4 AA or
AAA batteries, or 2 C or D batteries at the same time as you
charge a 9V battery.
2. When charging is complete, the 9V
charging indicator lights steadily.
Remove the battery.
Note: If other batteries are still
charging after the 9V battery is fully
charged, the 9V charging indicator
continues to flash until the other batteries are fully charged.
3. Unplug the adapter from the AC outlet.
Warning: To prevent damage to
your charger and risk of electric
shock, always unplug the AC
adapter from the AC outlet before
you unplug it from the charger.
Cautions:
• After you unplug the adapter from
the AC outlet, wait at least 3 seconds before you plug it into the
AC outlet again.
• Be sure to remove all batteries
before you unplug the adapter to
prevent battery leakage that will
damage the charger.
