Nickel-Cadmium (Ni-Cd) Charge Programs - GRAUPNER ULTRA TRIO PLUS 16 Operating Manual

NiCd
MODE
AUTOMATIC-
program
A set of convenient charge programs for recharging Nickel-Cadmium batteries, as commonly used for
modelling purposes. When the charge / discharge program is fi nished, the screen displays the name
of the charge program alternating with the message „END", together with the charge time, the last
(dis-) charge current, the charged-in (discharged) capacity and the battery voltage, and continues to
do so until you disconnect the battery. This information can often give you a useful indication about the
Ni-Cd pack's charge characteristics and capacity, or warn you if the charger has incorrectly assessed
the pack as being „full".

program
Ni-Cd automatic program
In this program the charger detects the type of Ni-Cd battery
connected to it, and adjusts the charge current accordingly
to avoid overcharging the pack.
The maximum charge current can be set before you con-
2 sec.
nect the battery to be charged. This is done using the INC
< 2 . 5 A
/ DEC buttons; the range available is 0.1 A to 10 A, or no
restriction. The charge process is terminated auto-matically
in accordance with the values already set for „Ni-Cd Delta
Peak cut-off voltage".

Ni-Cd discharge program
The typical purpose of this program is to determine the
residual capacity of a transmitter, receiver or drive battery,
or to discharge the pack to a defi ned level.
2 sec.
In this program the charger discharges the pack using the
4 . 8 V
set discharge current (0.1 ... 5.0 A, left of screen) until its
voltage falls to the set fi nal discharge voltage (0.1 ... 16.8 V,
right of screen).The set fi nal discharge voltage should be a
+ -
value of around 0.9 ... 1,1 V per cell, in order to avoid the
INC DEC
pack becoming deep-discharged. Deep-discharging a pack
runs the risk of reversing individual cells, i.e. they exhibit
reversed polarity.
NiCd
MODE
discharge
program
Select this program when you simply wish to recharge a
battery using the set charge current.
You can adjust the charge current using the INC / DEC
buttons, but only before you connect the pack for charging.
The range available is 0.1 A to 10 A.
The charge process is terminated automatically in accor-
dance with the values already set for „Ni-Cd Delta Peak
cut-off voltage".
