Charge And Discharge Programs; Program Flowchart; Selecting The Charge Program Group; Using The Charger For The First Time - GRAUPNER ULTRAMAT 12 Operating Manual

6. Charge and discharge programs

The various facilities of the charger are divided up into four program groups which you can select by
holding the MODE button pressed in for two seconds. The sequence is shown in the flow chart
below.
Ni-Cd battery programs: charging, conditioning, discharging to determine capacity or residual
capacity, or to select cells.
Ni-MH battery programs: charging, conditioning, discharging to determine capacity or residual
capacity, or to select cells.
Li-Po / Li-Io battery programs: charging, discharging to determine capacity or residual capacity, or to
select cells.
Lead-acid battery programs: charging, discharging to determine capacity or residual capacity, trickle
charge for stand-by operation.

When the ULTRAMAT 12 is initially connected to a 12 V car battery, the unit runs through the
information routine which provides you with a brief summary of the essential user settings. The
charger's screen displays the following information in sequence:

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".

9. Using the charger for the first time

The charger is now ready for use.
For charging / discharging, or conditioning a pack, select
the desired program as described below, and then set
suitable values.
Hold the START button pressed in for about two seconds,
and the charger will measure and assess the battery.
You can interrupt the charge process at any time with another

Note: if you interrupt the charge process by pressing
the START button, all display parameters are
irretrievably erased.
