INTRODUCTION
This unit is a two stage, constant current
battery charger for charging nickel-metal-
hydride type rechargeable batteries. The
charge termination is by a 14 hours timer at
which time it will switch from the charge
current to a low rate current. A 6 feet long
output cable with a barrel plug is provided.
There are two indicators on the front panel.
The orange light indicates that the charger is
in the charging mode. The green light
indicates that the battery is fully charged.
ASSEMBLY INSTRUCTIONS
Loosen the screws on the charger output terminal
strip. Identify the polarity of the terminal strip ant
the output connector; both the charger housing
and the output cable are marked with “+” & “-”
symbols. Insert the two spade terminals under the
terminal strip screws and tighten. To prevent
accidental shorting, cover the exposed terminals
with the molded press-on terminal cover.
If using loose wires, insert stripped ends under washers. A cable having a shield may be
grounded to the bottom hole using a number 6-32 x ¼” machine screw.
OPERATING INSTRUCTIONS
Before using this battery charger, make sure it is compatible with your battery. Refer to
the ratings on the battery charger, the specifications in this manual, and your battery
documentation. Charge only nickel-metal-hydride
type rechargeable batteries; attempting to charge
other types of batteries may result in battery damage.
This unit is provided with a polarized barrel plug
connector. Make sure your battery connector is
wired to match the output connector.
CAUTION:
This unit is not reverse battery protected except by use of the polarized
connector. Make sure your battery connector is wired to match the charger connector or
damage to the battery and charger may result when power is applied. While in a reversed
condition the charger will indicate that it is in the charging mode. However, it may
actually be discharging the battery until either the battery or charger is damaged.
