APPLICATION NOTE NUMBER 10

INITIAL COMMISSIONING CHARGE FOR NICKEL CADMIUM BATTERIES USING NRG CHARGER

Some nickel cadmium (NiCd) batteries require a high voltage commissioning charge upon installation. Some battery manufacturers, for instance, recommend a commissioning charge of 1.55 volts per cell for 48 hours or 1.65 volts per cell for 24 hours. This required voltage is higher than the normal “boost charge” voltage of the NRG charger, and must be maintained regardless of current demand. This application note describes how to manually set the NRG charger to achieve the high voltages required for NiCd commissioning, how to override the NRG’s automatic release from boost charge voltage, and how to readjust the charger back to factory settings once commissioning is complete.
