9.3.11 Program 224: Charging NiCd battery MARATHON
Name according to manual:
Charge (Constant Current) for MARATHON with main charge current
24: NiCd battery MARATHON
select Batteryprocessing:
P2: Charge
Enter:
Number of cells
Rated capacity
Charging current main-charge
Step 1:
Charging with charging current main-charge until a charging voltage of 1.55
V × number of cells is
reached.
After that a signal requests the measurement of the single cells voltages. In case the voltage is below
1.55
V charging continues for 5 minutes and again a cell voltage measurement is requested.
Otherwise step 2 follows.
In case the number of measured cells does not conform to the number of cells for example a cell has
been measured twice the device is not able to decide how to continue and the user is asked if all cells
are > 1.55
V. Enter: 1=YES 0=NO.
Step 2:
Topping charge with 0.4 × charging current main-charge for 1 hour.
15 minutes before the end of the topping charge a signal requests to control the electrolyte level.
In case no automatic cell tester is connected:
Before the end of the topping charge a signal requests the measurement of single cells voltages.
End of program
Voltage monitoring:
Monitoring minus ΔU > 30mV/cell during charging, error message:
minus delta U detected
