Nickel-Cadmium (Ni-Cd) Charge Programs - GRAUPNER ULTRAMAT 16 Operating Manual

program
A set of convenient charge programs for recharging Nickel-Cadmium batteries, as commonly
used for modelling purposes. When the charge / discharge program is finished, 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".

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
connect the battery to be charged. This is done using the
INC / DEC buttons; the range available is 0.1 A to 8 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 manual 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 8 A.
The charge process is terminated automatically 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 defined level.
4 . 8 V
In this program the charger discharges the pack using the
+ -
set discharge current (0.10 ... 5.00 A, left of screen) until
INC DEC
its voltage falls to the set final discharge voltage (0.1 ...
16.8 V, right of screen).The set final discharge voltage
should be a value of around 0.9 ... 1,1 V per cell, in order
to avoid the pack becoming deep-discharged. Deep-
discharging a pack runs the risk of reversing individual
cells, i.e. they exhibit reversed polarity.
