- Page 3 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.
- Page 4 CHARGING light will darken and the green READY light will come on. At this point the battery is fully charged. When the charger is in the float charge mode a constant current (1/4 that of the rated output current) is delivered to the battery to keep it fully charged. Most nickel cadmium batteries may be left connected to the charger in the READY (float) mode, indefinitely, without a danger of overcharging.
- Page 5 CHARGER STARTS UP IN READY MODE -If the charger READY light comes on when you first attach the battery (or in less than 13 hours) then the battery is probably more than 14.4 volts (12 cells). The charger resets into float mode when it detects a voltage over 21 volts.
