9.4.2 Program 321: Capacity Test NiCd battery HAWKER
Name according to manual: Capacity Check for HAWKER with C

21: NiCd battery HAWKER
select Batteryprocessing:
P3: Capacity Test
Refer also program 421 Maintenance.
While the program P3: Capacity Test requires a fully charged battery, the program maintenance can
treat partially charged batteries. After the program maintenance you get a fully charged battery. After
the program P3: Capacity Test the battery is discharged. After a waiting period of at least 8 hours,
the battery can be recharged.
Enter:
Number of cells
Rated capacity
Query, when the cell test measurement should be taken
(80 - 100% or 48 - 60 minutes)
Step 1:
Discharging with C
1
until battery voltage has reached 1 V × number of cells.
In case no automatic cell tester is connected:
After 48 minutes a signal requests the measurement of single cell voltages.
Otherwise: The actual discharge time will be registered automaticly when one of the cells is dis-
charged below 1.0 V.
After that continue discharging with C
1
until the battery voltage has reached 1 V × number of cells.
WARNING NOTE: „Battery discharged“
End of program
In case an automatic cell tester is connected:
Displayed is the capacity which was measured during discharging until the moment when the first cell
has decreased below 1 V.
Example:
Connected is a 24 V battery with 40 Ah. The battery will be discharged with 40 A to 20 V.
Time monitoring:
Discharging maximum 90 minutes.
