FEATURES

Your RadioShack Ni-Cd and Nickel Met-
al Hydride Rechargeable Battery Pulse
Charger lets you quickly charge five dif-
ferent sizes of standard nickel-cadmium
(Ni-Cd) or nickel-metal hydride (Ni-MH)
batteries.

The charger’s four battery chambers let
you charge up to four batteries of the
same size and type — AAA, AA, C, or D
— at the same time, while the connector
inside the charger lets you also charge
one 9V battery. 

Your charger has these features:

Intelligent Discharge System (IDS) —
automatically discharges and conditions
cells to a suitable level before recharg-
ing, to ensure maximum charging ca-
pacity.

Microprocessor Controlled Charging
— automatically detects the battery type
and monitors the charging process to
ensure the right amount of current is
supplied.

Soft-Start Charging — gradually in-
creases charging current when batteries
start charging to avoid heat build-up that
can reduce battery life. 

Fuzzy Logic Intelligent Charging Cur-
rent Control
 — automatically senses
when a battery is fully charged and
switches first to top-off, then trickle-
charge, to prevent overcharging.

Red LED Indicator — shows 9V battery
charging status.

Liquid Crystal Display — shows AAA,
AA, C, or D-size battery charging status.
