NiCd conditioning program
INC
This program is designed to optimise the capacity of a battery,
and balance the state of its component cells.At top right you
can set use the INC or DEC buttons to determine whether the
conditioning program is to start with a charge or discharge
cycle. After this you set the number of cycles from 1 to 5 (e.g.,
if you set three cycles, the pack will be charged and discharged
three times). The program discharges the battery using the set
discharge current stated on the right of the screen (0.1 ... 5.0
A), and then recharges it using the charge current (0.1 ...10.0
A) shown on the left of the screen. The
charge
process is ter-
minated automatically in accordance with the values already
set for „Ni-Cd Delta Peak cut-off voltage“. The
discharge
cut-off
voltage is set in the Ni-Cd discharge program. The method of
reading out the values for the actual cycle is described in the
section „Screen displays“.

The discharge balancing program does discharge and balance
up to 8 cells of a battery pack.
The fi nal discharge voltage for the balancer can be set within
the range 1.20 … 1.30 V using the INC or DEC button.
The individual cells in a battery should be balanced before
the pack is charged, to avoid the possibility of individual cells
being overcharged during the charge process. A battery should
always be balanced before being charged if it has been stored
for a considerable period;
connect the balancer plug to the charger to carry this out.
It is also essential that the voltage of each cell in the pack should
be higher than the set balancer fi nal discharge voltage.
If you wish to obtain maximum battery capacity, the individual
cells should be discharged to 1.20 V a few hours - but no longer
than two hours - before the next charge process. If the voltage
falls below 1.20 V, the battery cells lose capacity, so the pack
must be charged to around 60% capacity before being stored
for a protracted period.
The program discharges the battery pack at a rate of 0.1 A
… 5.0 A. Cells with a higher cell voltage are discharged at an
additional current of around 100 mA (balancing current). The
charger terminates the discharge balance process once all
the cells have reached the balancer fi nal discharge voltage
(+0.01 V).
