Repeat for the NiCd Standard Charge action but use these parameters:
•
Charge Current: 0.1 C (this is a slow C/10 charge that equalizes the cells without overcharging).
•
Write to results every: 30 seconds (saving the results more often than this gives no additional useful
information).
•
Capacity (fraction): 0.3 (at the C/10 charge rate this gives about 3 hours of charge).
Click OK to save these changes.
Now click on the NiCd Discharge action and fill in the fields as show below:

The UBA Let's Get Started Guide
Load:
Select Relative.
Enter “0.2” for the Discharge Current.
This is the IEC standard and will
discharge the battery in approximately
five hours.
Enter “30” for the sample time. Since it
will take five hours to discharge the
battery it's not necessary to save the
voltage and current more often then this.
Enter “10” (mV/cell) for the
Peak Charge finish criteria. Thus
when the cell voltage drops 10mV
below its peak value, charging
stops.
Enter “0.05” for the
Minimum Charge so that during
the first 5% of the charging any
voltage peaks are ignored. This
skips false peaks that can occur
at the beginning.
