GENERAL DESCRIPTION
This unit is a two stage, constant current battery charger for charging nickel cadmium type
rechargeable batteries. The charge termination is by timer (13 to 15 hours standard) at
which time it will switch from the charge current into a float charge mode at a reduced
current. An output cable, 6 feet long, 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 and
the output connector; both the charger housing
and the output cable are marked with "+" & "-"
symbols. Attach the two spade terminals to the
terminal strip and tighten the screws. To prevent
accidental shorting, cover the exposed terminals
with the molded press-on terminal cover.
Loosen the screws on the charger output terminal
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 cadmium and 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 will actually
be discharging the battery at the rated charge current until either the battery or charger is
damaged.
CAUTION!
This unit is not short circuit protected - it will deliver the full rated current into a
short. If the short is not removed, the charger may overheat and be damaged. While in a
shorted condition the charger will indicate that it is in the charging mode. If the charging
light is on while not connected to a battery then there is probably a short in the output
cable or connector. Remove the output cable to see if the charge light goes out. If the light
stays on without an output cable connected then there is a problem with the charger.
Plug the battery charger into a properly grounded (3-prong) wall outlet which supplies the
correct input power as marked on the unit. The indicators should be dark until a battery is
attached.
Attach the output connector to the battery connector. The charger should now be on and
charging the battery. The orange CHARGING light should be on. If the green READY light is
on instead, then the battery voltage is probably too high (too many cells). The battery must
be a 1.2 to 14.4 volts (1 to 12 cells) battery.
The orange CHARGING light indicates that the charger is on and in the charging mode. The
charger will deliver a constant current (rated output current) to the battery for 13 to 15
hours. After this time, the unit will switch into the float charge mode - the orange
