APPLICATION NOTE
8
1. Use the Volume and Weight parameters for NICD cells only to simulate a discharge rate grater than
approximately 5C and when the temperature profile of the cell is needed.
2. Although real NICD C and D cells can be purchased, most consumer C and D batteries are actually SUB C
cells in a big empty can.
Example Circuit of NICD AA and N Cell Discharge Test
To demonstrate the use of a cell in an actual circuit a real AA NICD cell is discharged into a constant resistance
of 2Ohms.
Then the circuit shown in Figure 4 is used with PSpice to simulate the 2Ohm and 5Ohm discharge. Running this
circuit with the capacity of the NICD model normalized to the actual capacity of the measured cell, shows results
which compare very favorably with the real behavior.
