Schritt 5:
Discharging with C
1
to 1 V for each cell.
In case no automatic cell tester is connected:
After 48 minutes a signal requests for measurement of single cells voltages.
Otherwise:
Cell measurement is performed automatically once a cell has fallen below 1.0V.
Thereafter further discharge C1 to the voltage of 1 V per cell is reached.
The determined capacity in this step is used at the end for the battery rating.
Step 6:
8 hours break.
The message is displayed:
„wait 8 hours.
skip waiting time possible: press .“
Step 7:
I-Charge with C
1
until charging voltage of 1.55 V × number of cells is reached.
Step 8:
Topping charge with C
5
for 2 hours.
In case no automatic cell tester is connected:
15 minutes before the end of the topping charge a signal requests for measurement of single cells
voltages and to control the electrolyte level.
Otherwise:
Cell measurement is performed automatically und you are asked to control the electrolyte level.
End of program.
In case an automatic cell tester is connected:
The capacity which was measured during the discharge until the time will be displayed, until the first
cell has fallen below 1.0V.
Excample:
Connected is a 24 V battery with 40 Ah. The battery is discharged with 40 A to 20 V.
Waiting time 8 hours.
After that the battery will be charged with 40 A to 31 V. Furthermore the battery will be charged for
another 2 hours with 8 A. The battery is discharged a second time with 40 A at 20 V.
Waiting time 8 hours.
After that the battery will be charged with 40 A to 31 V. Furthermore the battery will be charged for
another 2 hours with 8 A.
