Program 721: Reconditioning NiCd battery MARATHON
Name according to Manual: Reconditioning
24: NiCd battery MARATHON
select Batteryprocessing:
P7: Reconditioning
Enter:
Number of cells
Rated capacity
Charging current main-charge
Waiting after program step “Deep Discharge”? (see step 4)
Step 1:
Discharging with C
1
until voltage of 1 V for each cell is reached.
Step 2:
Afterwards discharging with C
10
until a voltage of 0.5 V for each cell is reached.
Step 3:
Deep discharging with device integrated 1 Ohm resistor over each cell for 12 hours.
Step 4:
D
epending on settings the device might wait after executing Step 4. This will prevent, that e.g. in the
night the request to control the electrolyte level might occur.
Charging with charging current main-charge until the charging voltage of 1.55 V × number of cells is
reached minimum duration 150 minutes.
In case the voltage is under 1.55 V the charging continues for further 5 minutes and a new
measurement takes place.
Step 5:
Topping charge 0.4 × charging current main-charge for 2 hours.
15 minutes before the end of the topping charge you are asked to control the electrolyte level.
End of program
Time monitoring:
Discharging with C
1
maximum duration 90 minutes, discharging with C
10
maximum 180 minutes.
