• If the battery is unsuitable for
charging, appears on the dis-
play. Do not attempt to charge a
bad battery. At the end of a nickel-
cadmium or nickel-metal hydride
battery’s useful life, it must be
recycled or disposed of properly.
Contact your local, county, or
state hazardous waste manage-
ment 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 (nickel-
cadmium only), recycling collec-
tion centers, and mail-back pro-
grams.
• The checking process drains cur-
rent from batteries. Therefore,
repeatedly checking the same
batteries decreases their voltage.
3. To check another battery, repeat
Steps 1 and 2. To charge the bat-
tery, see “Charging AA/AAA/C/D
Batteries.”
CHARGING AA/AAA/C/D BATTERIES
This graph shows the estimated typical
fast-charging time for different sizes of
batteries. Note that charging times in-
crease when more than one battery is
charged.
Note: Charging times are typical; actual
charging times might vary. The built-in
Fuzzy Logic Control automatically deter-
mines the optimal charging current,
which in turn determines the charging
time.
1. After connecting power to the
charger, open the cover and place
up to four AAA, AA, C, or D batteries
in the charger, one battery per
chamber, as indicated by the polar-
ity symbols (+ and –) marked inside
the chambers.
