Enter:
Nominal voltage
Rated capacity
Step 1:
Discharging with C
1
until the voltage of 1.67 V for each cell is reached (20 V at 24 V nominal voltage).
After 48 minutes a record is printed (80 %).
After that continue with discharging C
1
until the complete time of 54 minutes (90 %) or until the volt-
age of 1.67 V for each cell is reached.
Step 2:
Charging with C
2
and 2.33 V for each cell for 7 hours.
End of program
Displayed is the capacity measured during discharging:
Example:
Connected is a 24 V battery with 40 Ah.
The battery is discharged with 40 A to 20 V.
After that it is charged with 20 A to 28 V.
