• Do not overcharge batteries. Pro-
longed 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 dis-
charged 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 charge when they are
cold. If the area is too warm, the
batteries can permanently lose
their ability to charge.
Charging Batteries
1. Place a pair of AAA, AA, C, or D
batteries in one or more of the
battery chambers, as indicated by
the polarity symbols (+ and –)
marked inside each chamber.
Caution: Before connecting the
charger to AC power, be sure all
batteries are installed with correct
polarity. If you install batteries with
incorrect polarity (+ and –
reversed), they might not charge,
and the batteries and charger
could be damaged.
To charge one or two 9V batteries,
push their terminals onto the con-
nectors inside the charger.
2. Plug the supplied adapter’s phone
plug into the
AC12V 0.6A
jack on
the left side of the charger. Then
plug the other end of the adapter
into a standard AC outlet.
The green indicators on top of the
charger light to show that the bat-
teries are charging.
