KPH TYPE (High Discharge Rate Cells)
KPH Series high rate nickel cadmium battery is made of pocket plates. It has the characteristics of thin plates, high porosity, and low internal resistance. The battery is particularly suitable for high discharge rate applications such as UPS, switchgear tripping and closing, etc.
Applications:
engine starting, UPS (up to 30mins),operation and control of DC motor, water treatment plants,etc.
Charge:
The most common type of charging for stationary batteries is modified constant voltage, usually with current limitation of 0.2ItA or 0.1ItA (C/5 or C/10). The battery is connected to the charger directly which applies a constant voltage across the battery terminals.
Recommanded single cell charging voltage:
Float charge: 1.41+0.01
Equalizing charge: 1.60
Initial charging
The whole charge should be carried out preferably at constant current. The charging time is inversely proportional to the current which is set by the current limit of the charging equipment. Recommened rates and time for the first charging:
0.21tA for 10 hours
0.1 ItA for 20 hours
